4:21 Ray, that's a captured washer. It's a bolt with an integrated washer. 4:32 Would it not have been easier to place the bolt head on a bench vice to remove the washer? Would it?
I'm 80 yrs old and I'm very happy to see a young man that cared about the customers. I wish you were around here. I'm proud of you and I'm sure your parents are also. I'll say (thank you) for all of the customers that didn't I wish you well and a happy life.
You know there's plenty of other mechanics who care about their costumers, it's just that they don't film for clout and can therefore work much faster and not get fired from their job, lol
I own a shop and I can’t tell you how bad I’d love to have guys be this happy at work and to like what they do. Good help is hard to find even when they even get paid well!
Does he even have a right arm, that is amazing. I cuss like a sailor and blast ACDC while working on cars... definitely would be fired on my first day.
@Steve Ross *BINGO, honest mistakes which are learning moments and being admitted to show an honorable person.* Especially considering he was just 18 years old, too bad he quit that job!
A tip for stuck crush washers I learned at my dealership, grab the washer with some pliers and ratchet the bolt off in the loosening direction. It threads off the washer like it would out of the pan.
But sometimes you got a head engineer because they make it so hard to do a simple job my Jeep there were three different ways to have the air filter set up they did two of them
Changing the biscuits in my van's glovebox (chunky little cabin filters on a GM minivan) made about a ten degree difference last summer (2020) when I charged it after it sat for 2 years unused, and I didn't have to touch it this summer other than verify pressures with the gauge set. Next AC project for me is figure out why my wife's Explorer is bipolar on the passenger side. She'll get cold air out the driver vents and the passenger front vents will cycle hot, cold, hot, cold, with clunky "oh no my servo is worn out" noises to match. Really not looking forward to maybe pulling the entire dashboard. And then I need a heater core in the Town Car and that's another whole dash coming out I don't want to do.
@@robertreed1817 I have two Jeeps and changing the internal air filters is a PITA. I have to remove a bunch of stuff like the glove box to even get to the filters.
My second job at 18 I was convinced I could run the backhoe.... Remembering the large tail of the backhoe was an issue for me that resulted in my hitting the company office roof with it turning the backhoe.... my career as a backhoe operator at that company was short-lived.
i ran an excavator into the garage door at my job thinking i could fit through without having to get out and open the door all the way. knocked the whole garage door off. everyone laughed including my boss. spent the entire next day replacing the door and didn’t get in any trouble for it. was told that’s how we learn and get better. thankful i had a cool boss. i know too many people who get fired for far less
@@ethanclark9001 yep reminds me of this very tall reach forklift, we had several dock doors, many of them are regular tractor trailer height. he was supposed to enter thru "crane access" doors which rose all way up 50+' up he drove through one of shorter one, smacked top two forklift posts against the wall above the door and spring assembly for door just went *pffft* crunch inwards into wall. he stopped and ran away because, he knew the spring tension on those door is super dangerous. he got his manager and they both stared at the door. the senior manager laughed his ass off " someone else would do this.. AGAIN" the guy asked him " what happened to that guy? " " that guy IS ME" he did exact same thing in 1989 hes still there. so yeah we had to repair the wall, dock door, spring assembly, door guides, this time we painted top of walls in BRIGHT yellow with hazard stripe across it , with height marking, the GM of the warehouse wasn't too happy though but no one got fired. just a overhaul on doors and painting from that point on.
Gonna be honest, a shop that leaves the ‘still in high school 18 year old’ alone in the shop on his first job, that’s on the shop. They’re gonna mess up no matter who they are.
Literally, it's not even about competence in that regard, it's about experience. Obviously someone that young that's most likely new to all of this is probably gonna make a few mistakes if left to do the work alone. 100% on that shop.
I have once had a job as a youngster in a home improvement store where I was left on my own without any training on the job. A job where I had to use a large vertical saw to cut wood for costumers, without ever showing me how to use it and handle it safely and correct. Since I wasn't fed up with my hands, I walked away from the job the next day. Proper training and on the job and personal coaching by a senior is essential for ever job and newbie landing that job.
@@HarrieWorst hell, sometimes proper training by a tech school teacher won’t be adequate. Once had a teacher tell me to adjust the on-car brake lathe arms by hand rather than the adjusters. I basically told him to fuck off, I wasn’t gonna lose my fingers to his bullshit.
I've been a network engineer for 25 years, I've always had my car serviced by others. These video's are awesome. I have so much more respect for your profession now. Easily as complicated and requiring problem solving as any IT job. Good Job, I wish you could service my car down here in the AU, and I wish I could find IT people with your skills. Pay grade difference is not fair.
You think the paygrade difference isn't fair? Where I live (Germany) mechanics earn between 60-120€/hour, which is more than what you make with an IT job, even considering the down time when there's no customers.
@@StephenFasciani Absolutely, Learn from others in REAL life, not from uni. You'll encounter problems require YOU to use skills not trained. Basics first. Problem solve second, education third.
@@AlpayYi 9/10 the tech aint making that rate, thats what the shop is charging for their labor rate, thats generally not what the techs are paid. Most dealer techs ive known have been in the 30-50 range as their actual payrate.
A piece of advice I learned in my 35 years of doing ac work is always put oil on any o-rings on the the lines, sensors, Schrader valves, etc. I almost never had a leak from the o-rings. Always put oil on the o-rings before you put it back together it will save you time in the long run and it only costs you a few seconds.
Indeed.. oil on o rings help prevent pinch. Oil on all helps also have gaskets, o rings, and schraders swell and is better when pulling vacuums. Micron guages.
G'day Ray everyone makes mistakes especially when we are young and learning but it takes a real person to admit it and move on, it also shows good character. Well done regards John
I applaud you for admitting a mistake was made and not an excuse. You make me proud to be subscribed to your excellent channel. Kids now days just lie and blame everything but themselves for the mistakes they make it seems. It’s refreshing to watch an honest man doing honest work.
In auto tech school I found the instructors were weak on AC knowledge, I took intro to commercial HVAC and got the real scoop, the exact science of it, it helped me understand tremendously! At idle and no air moving over the front the AC system will at best maintain what you have, or bring it down a few if the inside is scorching hot, it will not cool the inside as it should, the comp is designed to work best at ~ 2000 RPMs, while the vehicle is in motion. But that machine measures the exact amount of freon so if you evac and recharge you should be good, just remember vent temps are not gonna be as good in that shop at idle with no air flow, go for a drive then you will see. And some vehicles have pressure activated fans, they turn on too late to do any good IMO. If you have a chance, with gauges hooked up, wet the cond down with water, watch how much your pressures drop, lower pressure at full charge = colder human. TXVs rarely if ever gives problems, especially with 134A, now the old R12 would turn your system into an acid nightmare with just a small amount of moisture, thank god you don't have to deal with R12 in Florida with all that moisture.
Ray - you hit the nail right on the head when you were looking at the temp and pressure chart. Nobody ever figures in the humidity. I am in commercial A/C and the Dewpoint temperature is so important yet nobody talks about that either. That is a real big deal for you in Florida.
Hmmmm, not with respect to just refrigerant pressures. I agree the humidity saps capacity from your system because it is pulling moisture out of the air stream but the refrigerant just "sees" dry bulb temp because its a closed system. Humidity is never on the refrigerant pressure charts.
Noobie question. When you read refrigeration temp charts, how do you account for the way the readings shift as the compressor starts and stops? Do you record cut-in and cut-out readings for both the high and the low side, and compare those four readings to the four readings shown in the graph for the ambient temp?
Oh man I once skipped few steps and almost ruined a robotic arm on assembly line worth about 50k. Luckily for me nothing broke, nothing bent, nothing stretched and all I had to do was recalibrate it. Nobody knows, only me and all of you but boy sweat was pouring down my back until I was done with what had to be done and it turned out OK :D
I put the end of one through a fence. partly. 'yeah, that dent's always been there'. taught it home, hammered the fence flatish, and never complained about keeping the robot at 5% speed when teaching again.
Just a note, as a Kia technician, at the connectors from the evaporator to the expansion valve through the firewall on the newer vehicles with 1234yf. We find corrosion a lot of times causing a leak so it’s a good idea to pull the expansion valve to see if the evaporators leaking. However I’ve not found it very often on these older optimas with 134
I'm retired but worked on a school fleet in Phoenix when I was a young man and air conditioning was R12. We never evacuated, simply took out the valves and let the freon blast out. R12 was cheap. We just did the repair and filled it a bit and started the vehicle up and kept filling until the pressures looked about right. Those big bottles of R12 were about 30 bucks.
Thanks for sharing that "screw up" story.. Love listening to them, for some reason... lol Thank goodness it didn't bend any valves on ya! One I can remember was back in '99 or '00 when I was 19, at my first shop. I was doing an oil change on one of those mid 90's Lincolns (with the air suspension switch in the trunk, that you're supposed to shut off before lifting the vehicle).... Well, of course I was in a rush that day and forgot to turn the switch off while doing an EOS. I drained the oil, changed the filter, etc and then realized after letting it back down, the car looked like a lowrider in the back (I'm sure anyone who's dealt with those knows exactly what I'm talking about!). So, I immediately panicked (and prayed I didn't damage the air bags) and fired the engine up to see if it was alright... It was fine. BUT after about 45 seconds to a minute of watching the thing pump back up, I remembered I didn't put any oil back in it!! I RAN and shut it down, and filled it with oil, and WHEW!! It was ok... That scared the crap out of me though. LoL
Have to admit I'm HIGHLY impressed with the serviceability of the Optima/Sonata late models. Why pull whole service covers when you can have a hand sized hole? The AC components are all within reach. The air filter box isn't buried into the fenderwell. Things are where you'd EXPECT them to be?!! Did they hire a mechanic to be an engineer QA consultant over there? Good on them!
A lot of Hyundais are pretty good with that. There are some exceptions but typically those are more reserved for higher end vehicles like the entire Genesis line Equus/Azera's. Newer cars generally still have some of a splash shield but you only need to take off a couple bolts and a few plastic tabs.
@@AmazingFlyingSquid More chance for someone to lose the bolts. Or have tabs broken. I much prefer this design. Heck, even have a service hatch or cover of sorts would be good. I know some cars have covers to access fog light at the wheel well.
I felt that until it was Sorento/ Optima(k5)/ telluride, day on the final gen of the optimal, and any Sorento after '15 it seems. The undercovers are brutal especially if you're unprepared, or your impact died. 15 10mm screws in the Sorento and about 8 give or take 10mm in the optima's
@@AmazingFlyingSquid the Azera is no problem. The drain bolt is exposed via an opening in the skid plates and the filter is mounted topside. Can be changed in the driveway. The Genesis however baffles the hell out of me. There IS an access hole for the drain bolt, buuut not the underside mounted filter. And because the skid plate is so encompassing there is no frame access for a standard jack so it requires a lift or recessed bay. The Genesis plate also requires the removal of 17 bolts to remove the plate. Ive owned both 2016 Azera and 2013 Genesis. Ive actually considered cutting a fold away panel so I can access the filter on the Genesis.
@@2010ngojo my 2001 Firebird has plastic covers where you access the fog lights. Prior owner cut flaps in the plastic for fast access. I am just fine with that.
@22:51 - keep in mind, you have the driver side window (and door, if app.) open. So hot air is getting inside the car from the bay. I would close the door and window and let it run for a minute or so for a better reading on the inside temperature.
The gauge is measuring the temp of the air blown in via the center vents, and the specs did say use outside temps to measure against, not recirculated air inside.
I have often seen that the excellent techs in a shop will always be the ones to freely admit their biggest screw-up. Your Volvo story told me you are one of the good ones. We all have them, and we learned from them. Me personally, to this day, when I do a tire rotation, I do not stop the procedure (no matter what happens around me) until I have rotated all four tires and TIGHTENED all lug nuts on all four wheels (it is either 20 or 25 of them every time).
First, good idea to do the tires all in one process. It's easy to forget when you stop for something else. Second, how can there be 25 lug nuts on a vehicle with 4 tires? Maybe you meant 24?
I had a customer come in for an oil change (that's it) and they came back later that day saying I didn't tighten their lug nuts. bring the car back and the lug nuts are literally stripped half way down the studs. Service manager tried to burry me as the scape goat until I mentioned to him the vehicle history showed brakes were done like 5k miles ago so I didn't even bother to check them and they didn't request a tire rotation so why would I bother taking them off? Furthermore, I explained that the lug nuts were stripped half way down the studs (the threads close to the wheel were gone, almost like the nuts were pulled off the stud, shearing the threads off) and 1, I had no clue how that could have happened, and 2, the vehicle was driving fine. when I pulled it around to give HIM the repair order. That service manager had the mentality that the customer could do no wrong and regardless what their complaint was, they were right and it was always the technicians fault. we had the highest customer service scores in the area, but the lowest shop morale when he was the manager.
Yep, same here. Basic rotation and oil change and tire work gets done first. Doesn't end till I have wheels torqued. Then I do the oil change. That way when it's on the ground it's on the ground.
Totally different setting, but as a climber I stop talking when I tie in to the rope on the ground. I force myself to finish the procedure before doing or even thinking anything else. I got to witness countless human mistakes as an instructor. The most common scenario was people getting distracted during a critical step ('oh wait let me get my shoes') and then forgetting to pick up where they left off and automatically going into the next step. When they also missed it during the final check I intervened by saying 'hey, you might want to check again'. It usually scared the shit out of them, and there was absolutely no need to for me to patronise. So if you ask me, it doesn't make sense to fire people for making mistakes. Humans make mistakes. The good news is that we learn from them. I'm a big fan of creating an environment where mistakes are shared, analysed and learned from rather than punished. I know a guy who's a programmer, and his boss put up a board to record mistakes, and when it reached a certain number he would buy the whole team cake.
I was surprised how much you knew about air air conditioning. I do air conditioning for a living.but just a tip before you do anything with evaluating a charge make sure there are no air flow issues. Eg: cabin filter, blocked condensed, dirty evaporator coil etc. you can solve a lot of problems mostly I checking superheat a lot of people don't do that A superheat reading will tell you so much about the system. Also if you're in the shop block off the condenser make the high side go up and see if the txv adjusts accordingly. Keep up the good job. You have a good channel.
Most auto AC guys know nothing about superheat. Knowing superheat, and watching it as load on the evaporator changes, will usually diagnose a sticking TXV or broken power elrment line in a minute. I too worked commercial/I industrial refrigeration for many years, everything from package units with tin can compressors to 150 ton chillers, factory trained by Carrier back when Syracuse waa still the HQ. Carrier went downhill as soon as UTC bought them out in the '80s to use it as a cash cow.
I have almost zero skills with engines etc... but I really enjoy your videos. and I am learning a lot of stuff! Still going to let a pro work on my car.
What brand is the ratcheting box wrench you used on the expansion valve, Snap on? Also, the oil change story is a good lesson for young techs. Admitting your failures and not making excuses, that's how you become a good technician.
Well done for owning up ! Only a guy who knows he has much more going for him will find that possible. 6 months ago I started my lawn tractor engine with one screw holding the fan guard down. It turned into a steel discus and slashed the top of the engine cover, ripped out the choke cable and cut a long gash in the battery, spewing acid into me and the concrete..which gassed me.. It finally hit me 1 inch away from crown jewels and cut a gash in my jeans a big graze in my leg.... The cover was folded up and mangled. Lesson learned.. If something isn't FULLY bolted down when you start up, it will blind you and eunuch you and bankrupt you and kill you !
I really love these videos, I love the simple video style with a couple of cuts and images edited in and how its not all flashy with high production value like every single other youtuber out there. Keep up the good work!
I agree. I hate it when other RUclipsrs start with loud music intros and codas. Just get to the show already! I've got many, many channels on a mental list that I refuse to watch any of their videos because of the level of stupid flashy intros and loud music. Then once you do finally get to the show, one minute in, you're met with a pair of commercials, the first one you can't click past it at all, then you have to watch the second commercial for five seconds before you can dismiss it, and again, this is just within the first minute of the video.
I'm a retired tech rep and you sir are the kind of tech I used to enjoy working with. It was a pleasure watching you work and hearing your thought process as you went through the diagnostics.
I been working on cars my entire life I only torque engine parts, and important parts there’s a lot of stuff that you can generally torque and it will be fine but some thing like anything in the engine has the be in spec and I’ve never had problems with this method
I'm a newer viewer, first time to leave a comment. I'm enjoying your content. You do a great job with video and walking thru step by step. I'm a commercial HVAC installer, service and repair tech. I like to make sure all vents are open and the filter is on the cleaner side when I'm looking at a service call. Then I like to run the a/c for 10-15 mins at normal outdoor temps. Then I look at the pressures and delta on the system, before I add or leak check system. I gone out on jobs that are over charged because the Tech didn't take the steps on trouble shooting a system. I learn things everyday, It doesn't mater how long your in the trade. We learn how to resource, to get the job done. Anyways enough of me talking. Again I like how you trouble shoot, document with video and notes! It makes it much easier to show a customer to help understand or to protect your Shop and your self Need more guys like you in these shops, doing what they love and taking care of the customers. Keep up the great videos and job!
A tip that i have when taking those washers off of honda/hyundai/kia vehicles is to use a set of vise grips to grab the washer and then use your wrench/ratchet to unscrew the drain plug from the washer.
The really expensive mistakes are the ones that really, REALLY, stick with you. I had a similar mishap in 1985 with a $23,000+ Circuit board in an Air Data Computer. A supervisor came up while I was working with the unit, wanting to talk, ask questions and generally shoot the breeze while I was working. I was distracted by the conversation and inadvertently swapped a power supply card with an Arithmetic/Logic Unit. All of the connectors were the same, with just a diagonal line on the tops of the cards (I think it was 14 cards in sequence) to differentiate locations. Being distracted, I did not notice my mistake before powering up the unit and watched the card as it smoked in less than 3 seconds. The ALU could not handle the input voltages intended for the power supply card. I wasn't reprimanded or made to pay for it, the supervisor knew that it was his fault for the distraction, but I sweated having to pay for that circuit card for weeks, on an E-3's pay. To this day, if someone comes up while I'm working, no matter what I'm working on, Cars, small engines, sewing machines, computers, cooking or whatever, I stop all work, wait for them to finish flapping their gums (which it seems is all they ever really want to do), and make sure of where I was at and what I was doing before the interruption while getting back to work. I've gotten to where I can barely tolerate anyone even watching me while I work and will stop until they get a clue and go away. Sometimes I even have to provide the "Clues" or I'd never get anything done. "Valuable" lessons last a lifetime. Thanks for sharing yours.
But that was on the bus not you we had a similar thing happened with one of our machines that went out to Vegas to a show and they had a throw this thing in a day and it was supposed to say the company one of the things we said was the battery terminal should be different so they cannot cross them they told us just get it to work okay fine not only did it work but it looked awesome 1 of 1 the entire company depends upon its success day two they hooked up the batteries backwards buzz buzz puffs they call us at home on a Sunday to ask how long would it take to build another one you said a day and a half maybe two but we don't have the parts that company is no more but we went into work and took everything all our tools everything before Monday even hit we knew that they were done so we got a ton of stuff out of there fiddled around Monday through Thursday Friday we will call to have a meeting companies closing don't come in Monday here are you a checks then he said go cash him now so they'll clear didn't understand we built the stuff we went and smacked engineers and said that won't work naked so it will repeat up the quality control guy because you took a magic marker and made lines and dots all over the place because the blueprints said if needed but it wouldn't go there physically in the real world that's why it was wired the way it was wired but it was permanent marker that was a different unit going to a customer I brought it to a friend that did airbrushing for cars the coven the lines and dots I had him charge them $5,000 for 1/2 hours work
Always double check the steps. Sometimes someone who's been working on cars for over 20 years could forget to put the drain plug in and attempt to refill the oil. The guys in the shop will never let me forget that day.
Just happened a few weeks ago, put the drain plug in by hand, got distracted by a customer telling me how to do my job, forgot to use a tool so of course "I wonder where that drip is coming from." Talk about embarrassment. Thankfully we double check every time to look for any potential leaks, hence how I found my mistake, so we didn't send it out the door, but it's not a good feeling when the customer sees the mistake in real time, that's for sure
@@bullypopful I hated that at a shop I used to work at, the customers would be over with you, not every one ofcourse but the odd one that never shut up the whole time. It’s OK to be friendly but hey, I am trying to concentrate on my job. Bad practice, customers should only be in the bay when you are letting them see something. To avoid the drain plug problem. I made myself a routine where I would never leave a drain plug hand tight, if it was going in it got tightened with the wrench. In and tight or not in at all.
I worked the pit at a quick lube many years ago, we had a kid working topside that started dumping blue water down the oil fill while I had the drain plug out of one we had in the bay
Most air conditioning on vehicles is designed for while driving conditions not parked. I am a refrigeration technician and I believe you just had leaky shrader valves.
Tip. Air over condenser makes a large difference. Put a large fan in front of the vehicle to move air over the condenser. Vehicle condensers become heat soaked with engine heat and don't allow from proper expansion.
i'm betting the good humor and bubbly personality allows for everyday struggles to be handled with more ease and less stress. this man seems like he handles himself well, handles the job well and can roll with the punches.
After watching a few of Ray's videos I find myself singng "doodle, oodle, oodle" every time I hear a phone ring! I "click" every time I tighten a bolt, too! Ray, you're creating monsters! ☺
I've turned wrenches off and on my entire life, my Dad used to race stock car, blah blah blah. That said, none of us were ever certified (ASE, etc) but listening to you, not just talk, but hold on a lengthy, one-sided conversation with rigs you work on, made me realize something. Now, since most us have held a conversation and ARGUED with a vehicle, I realize, speaking only for myself, that I must actually be a professional, knuckle-dragging mechanic!!! What solidified my thought when you stated that it became personal. Thanks for the videos, learnin and laughing are always fun.
@@RainmanRaysRepairs Try mouthing the word "I can't hear you" without actually saying anything and see how they react. I worked with a guy who was hard of hearing and I would start talking to him and slowly stop making a sound but would keep moving my mouth. His reaction was hilarious.
good job, really like that you just didnt replace the valve and let the customer see if its alright now. just in case they already have a diagnose from you in the future if the problem keeps coming back. greetings from Germany!
Every good mechanic has that one repair mistake that will give them nightmares for the rest of their life. If they say they've never made a mistake, they're lying.
Hello Ray. Next time you're trying to get the gasket off the drain plug, use channel locks & the ratchet/wrench you used. Grab the gasket with the channel locks, and just unscrew the gasket. Grip hard and should be good to go ~
I figured that was the obvious route, but hey, sometimes you do it for the show I guess. I don't do anything without a set of vice grips nearby. It's only detrimental, or a bad idea for those who don't use their brains while using them.
You got to understand that his a general mechanic, nothing special here. He's not fixing BMW's or other German cars that require special techniques and tools and brainstorming to repair them stunning pieces of machinery! lol
My first job was at the corner gas station. On the weekend after mechanics went home for the day. Some time we took in tire jobs and oil changes. Will this guy in a Corvette came in for an oil change. I turned him away said he need to come back when the mechanics were here. It was so low and we had center post lifts it just barely cleared. Well this guy I was working with heard me turn him down. He said I can do it. Well I was pissed and left him to it. At the time gm used two oil filters types / sizes. One had the gasket near the center and one toward the out side. I told him to put the right filter on. He said he knew what to do. This kid was a grandson of the owners best friend. Well he put the wrong filter on filled the oil ran it rechecked the oil and sent the guy on his way. I'm out side pumping gas as this guy backs out and heads to the exit. Soon as he put it in drive and gave it gas oil started pouring out the bottom. I dropped the pump handle and ran him down yelling to turn it off. I hand pushed it back in put the right filter on and refilled it. Saving the motor the station owner money. I told the owner what happened that night but that kid kept working but never changed oil or tires the rest of the time he worked there.
Great story. Everybody screws up and too bad this couldn’t have been a learning experience instead of not letting the guy learn and keep working. Unless he had a bad attitude of course. I worked at a shop, not sure how many years I worked there at the time but I used to order my own parts. I wasn’t just an oil change jockey, I was doing my apprenticeship and all kinds of work. One day I did a basic service but turned into some kind of extra problems, anyway at the end of it all I forgot to mark down an air filter on my work order sheet and the customer never paid for it. I realized it and told the boss right away, and before they found the mistake. After that I was no longer allowed to order my own parts. It really hurt and I always thought I would have rathered him warn me and say “next time it will come off your pay”, or I would have had no problem paying for the filter that time. People make mistakes - make them accountable but allow them to learn and go forward.
@@peterl2017 Completely agree! Good employees and bad make mistakes. The difference is what they do next. The good ones learn, the bad ones don't...or worse, they lie to cover themselves. That shop should have just let you be a good employee. Instead, it sounds like the only thing the boss would accept was a cover-up. I hope you quickly found a place worthy of you.
Just started watching your videos, pretty entertaining and I wish every mechanic would video their work because customers already assume they are going to get scammed before they even go in, this way its all right there. Do you show the customers your video?
When it's affresh washer there is no requirement to crush it any more than you would at the standard torque spec. That's precisely how the last one got so smashed. Remember, all it has to do is keep the oil in the oil pan. It doesn't have to support the weight of the car.
To be honest....on my vehicles I've never changed the washer /gasket if it isn't cracked. I put a thin coat of silicone sealant on it. Hasn't failed in 20 + years.
Awesome video and dead on suspecting a TXV issue till you noticed the system might be slightly low on refrigerant, 134A is very critical to proper charge to maintain best performance possible. The old r-12 systems were very forgiving on being a little low or a little high. I did find it strange you spent so much time checking and even replaced the core valves but didn't show inspecting or replacing the caps. The cap has a flat seal and are made of thick durable plastic, also the tops of the connections are machined flat and smooth to ensure proper sealing. The cap is the primary seal and the core valve is the secondary. you said you heard a whoosh when you took one of the caps off. This meant it was doing its job and providing a positive seal, core valves are not meant to be a 100% positive seal, they are mainly there to make the system serviceable easily. The main sealing is done with the caps and their rubber seals. Same with a tire valve, the core is secondary seal and the cap is the primary. That is why you should never not replace the caps with ones that are in good condition and have good seals in them. Hope this helps in the future. I always replaced caps and cores in sets to make sure both were in top notch condition.
I remember my worst screw up. I was still pretty green, doing fluid changes and entry level stuff. A customer brought in a 2002 Ford Explorer, yes I remember the exact year of the vehicle, my paycheck went to repairing my screw up. Lube, oil, filter with a trans drain and fill. Someone had stripped the torx drain/fill plug in the trans pan so I had to ease the pan down full. It ended up all over me. Cleaned myself up, cleaned the pan up, new filter, gasket and drain/fill plug, slapped it together and sent it on its way, they made it about three miles and it was towed back. Trans was bone dry. I did get to learn how to pull a trans on a 2002 Ford Explorer the next day. I was lucky enough to not get fired, I made right on the repair with the customer and continued to work and learn at that shop for three more years.

Back when I worked at Grease Monkey one of the things I always did was turned peoples high beams and fog lights off. It was nice to see someone else do that as well.
@@Billo-07 It seems like more and more people are driving around with their high beams on. It is kind of dangerous to drive at night now with how bright oncoming headlights are now.
You reminded me of my first car.. 58 Alfa Gulia Sprint GT. Dad changed out the original racing engine for the smaller one, but somehow or other we ended up with the wrong pan. After that, every time you checked the oil the stick would come up DRY because the pan that was on didn't have oil where the stick was.. I used to freak out gas station guys who would check the oil (1970's!) and kinda panic at the dry stick. I knew that if the oil pressure dipped on a hard turn I needed a quart. That car almost killed me though, it turns out that the smaller and lighter engine took the car from slightly nose down to slightly nose up. I was surprised one day when I went to change lanes and nothing happened, as if I had no steering. Bad thing at 75 MPH. Dad did teach me not to panic, and I just put the wheel back to center and backed off the throttle a bit, and was rewarded with my front wheels touching the pavement again! The front end was flying! Loved that car though, I wish I still had it. 5 speed synchro mesh, once rolling I never needed a clutch. :)
I remember reading a comment not too long ago basically stating "never roll down a customer's window." Thank you, Kia for showing everyone WHY we roll down the windows of our customer's vehicles
I'm retired now, but I ALWAYS rolled down a customer's window. I had 2 cars, early in my career, that I heard the dressed "chunk!" Of the power locks engaged when I shut the door, then waiting on a lock smith to come to the shop I worked at to unlock the door. I have a set of door opening tools, but the shop wanted a bonded locksmith to do it in case of damage, it'd be his problem, not ours
Polish guy called the dealer where he just bought a new car and asked, "What is the cheapest window on this car to break?" Dealer asked the guy why wanted to break a window on his brand new ride, and the Polish guy replied that he locked the keys inside the car. The dealer informed his customer that there was no need to break a window, he'd send a lot boy with a duplicate key. The Polish guy said, "OK, but hurry up. It's going to rain and I want to put the top up."
Yup. I always roll down a window in every car I pull in. I had one up on jackstands, in Drive, to check front wheel bearings. I got out to go listen at the wheels and the door shut behind me. When the wheels got to 9mphi heard the doors lock. Uh oh...had to call the customer for their spare key. After that every car gets the window rolled down. I'll risk having to repair a window once in a while as opposed to having keys locked inside again.
back in trade school, AC diag was by far my weakest class. I just couldn't wrap my head around the pressures and what the readings indicated what was wrong. The only thing I did store in memory was if both sides read low, the most likely issue was a low charge and since its a closed loop system, there had to be a leak. Somehow, when watching this video I saw the readings and immediately knew they were low but couldn't for the life of me remember what it should have been reading XD
High side should be about 2.2x ambient temp. Low side 20-40ish. If the low is high and the high is low @ idle then gets better if revved the compressor is weak. Pumps better @ faster speed.
Oil should always be added to the new filter when replaced. It even has pictures on the side of the filters of some manufacturers. It helps lessen the time the engine bearings will be spinning with no oil pressure.(this is important). If you feel uncomfortable adding new oil to the filter in the large center hole, mount the filter upright on the bench and add it to the outer holes so it will be prefiltered. It will take a little longer but it also takes time to drain the oil. Because I have weak arms( Muscular Dystrophy) I cheat by only half filling the Class 8 Diesel filters, but I prefill the filters. My Dad was a licensed old school mechanic born in 1902...and he added oil to his filters. Like your work Ray and I think you do a great job of filming your work Thank You
That looks like a 2011 or newer Kia Optima? I'm pretty sure that compressor has no clutch but, instead, has the solenoid valve in the back of it that likes to stick. The PCM regulates the compressor with by pulse width modulating that solenoid. I've seen them stick many times. Do a tappy tap tap on the compressor near that valve and see if it improves. That will also cause the intermittent issue they complain of and the pressures you noted.
@@TheGuruStud I just had a 2015 Corolla come in with this very problem. AC was intermittent. I finally got it to fail and while it wasn't working I tapped on the compressor near the solenoid. It immediately started working. Replaced the compressor. Nobody likes an expensive repair but they were very happy it was fixed. All these style compressors with the control valve instead of a clutch are prone to this type of failure. If the solenoid valve is sold separately you can just replace it. In most cases, it's not sold separately and you have to buy a compressor.
I have a 2014 Sonata that had a/c issues. Ice cold going down the road but come to a stop and idle it would barely blow cool at times. I replaced the solenoid in the compressor after about a year of owning the vehicle ( bought used in 2019). It ran a LOT better at idle but still not like I thought it should. I finally got around to replacing the TXR / Expansion valve about 2 / 3 weeks ago. Now it will get cold at idle without having to ramp up the RPM's and even colder going down the road than I thought possible. I know of a couple of other people that have the same vehicle with same issues and it's one of the other that has fixed it. No need for a new compressor which some shops will try to get you on.
A long long time ago, it was an automatic "lick" from the paddle if the old shop teacher found a loose drain plug. Either leave it out or tighten it, never leave it loose, that was his rule and he didn't kid around when he swung the paddle.
@@doji_town_adventures and that's the problem with the world today. Some people just need a kick in the ass to get things right. The problem is, it's illegal to give them that kick in the ass. If they want to do a certain job, they are going to learn how to do it. But they don't learn by being brought to the side and talked to nicely. That's just not how humans learn. If there are no consequences then you didn't do anything wrong. A paddling is a little of the chart, but if someone really wants to do their job properly they will accept it. Because in a few hours when that engine blows up because it doesn't have any oil, guess who doesn't have a job anymore.
@@mattevans1643 yeah you sound like someone who got beat into thinking it's normal. knowing you did something wrong should be a well enough lesson. if you need pain to learn your lesson you should probably be looking at a different profession because you don't seem to have the mental cut for it.
I remember changing oil on my dad's car, left the old oil filter gasket on and double gasketed the filter. He got towed to a garage where they fixed it. I was destroyed, he was pretty cool about it. The car was a new 1974 Datsun B-210.
Only did this twice in 50 years. Had gushers coming out of the flange of the filter housing. Mess was nasty. But no damage - other than to my pride. 2nd time I thought I checked - did not check well enough. Have not done it a 3rd time - yet.
Pretty cool of you to recount your mistakes. Nobody is perfect. Do you have a good relationship with other people at your shop? I'm curious about the environment of an auto shop. Also, I love the way you diagnose problems.
I left a breaker bar on the crank bolt by getting rushed and turned the engine over and broke the timing chain on a customers car once. Lesson learned, dont let people rush you.
When my service writers rush me I tell them "it will be done when im finished, if you want it done faster then it's not my fault and I better get paid if it cones back."
You have to be so careful in your job Ray one distraction and the shit hits the fan and so many mistakes can happen when you loose concentration, Been there done that. Keep up the great work Ray
I used to do auto AC work...mostly when R-12 was still the 'main coolant' in use. Most-all cars had the identical diagnosis...low-high, high-low readings, you'd replace the TXV, vacuum and recharge. Still a problem? You'd replace the dryer...going with the idea that 'it was plugged' (and that the TXV was now 'good', regardless). Blockages caused the 'opposite readings', in most-cases...but that was when compressors were either working, or they weren't...no real middle ground back then. Good thing was, it was fairly expected to get 35-38-F vent temps, on a good system, too. (I've seen frost blow out of vents in the summer, on Cadillacs back then)

Always check the cabin air filter. I have had several cars in the shop with the exact same symptoms (pressures) and the cabin air filter fixed it.
But sometimes you got a head engineer because they make it so hard to do a simple job my Jeep there were three different ways to have the air filter set up they did two of them
This was the exact issue I had once. The filter change made it better.
@@Daniel-wl7rl I have seen several models with a/c recirc filters. Most of the time it does not have one but I have seen it.
Changing the biscuits in my van's glovebox (chunky little cabin filters on a GM minivan) made about a ten degree difference last summer (2020) when I charged it after it sat for 2 years unused, and I didn't have to touch it this summer other than verify pressures with the gauge set. Next AC project for me is figure out why my wife's Explorer is bipolar on the passenger side. She'll get cold air out the driver vents and the passenger front vents will cycle hot, cold, hot, cold, with clunky "oh no my servo is worn out" noises to match.

@@ethanclark9001 yep reminds me of this very tall reach forklift, we had several dock doors, many of them are regular tractor trailer height. he was supposed to enter thru "crane access" doors which rose all way up 50+' up he drove through one of shorter one, smacked top two forklift posts against the wall above the door and spring assembly for door just went *pffft* crunch inwards into wall. he stopped and ran away because, he knew the spring tension on those door is super dangerous. he got his manager and they both stared at the door. the senior manager laughed his ass off " someone else would do this.. AGAIN" the guy asked him " what happened to that guy? " " that guy IS ME" he did exact same thing in 1989 hes still there. so yeah we had to repair the wall, dock door, spring assembly, door guides, this time we painted top of walls in BRIGHT yellow with hazard stripe across it , with height marking, the GM of the warehouse wasn't too happy though but no one got fired. just a overhaul on doors and painting from that point on.

Gonna be honest, a shop that leaves the ‘still in high school 18 year old’ alone in the shop on his first job, that’s on the shop. They’re gonna mess up no matter who they are.
Literally, it's not even about competence in that regard, it's about experience. Obviously someone that young that's most likely new to all of this is probably gonna make a few mistakes if left to do the work alone. 100% on that shop.
I completely agree. The shop f'ked up. You get the employees you train.
I have once had a job as a youngster in a home improvement store where I was left on my own without any training on the job. A job where I had to use a large vertical saw to cut wood for costumers, without ever showing me how to use it and handle it safely and correct. Since I wasn't fed up with my hands, I walked away from the job the next day. Proper training and on the job and personal coaching by a senior is essential for ever job and newbie landing that job.

A piece of advice I learned in my 35 years of doing ac work is always put oil on any o-rings on the the lines, sensors, Schrader valves, etc. I almost never had a leak from the o-rings. Always put oil on the o-rings before you put it back together it will save you time in the long run and it only costs you a few seconds.
i have always used a drop of air tool oil in every shrader valve i put in tires
@@mattcat231 ac oil on the ac system will save you a lot of problems
Good tip.
@@allanbarr5186 yeah, i don't get into AC work, i send that to my brother
Indeed.. oil on o rings help prevent pinch. Oil on all helps also have gaskets, o rings, and schraders swell and is better when pulling vacuums. Micron guages.
If we don't screw up we never learn. Its learning to not screw up again that is the art.

It’s refreshing to watch an honest man doing honest work.
In auto tech school I found the instructors were weak on AC knowledge, I took intro to commercial HVAC and got the real scoop, the exact science of it, it helped me understand tremendously! At idle and no air moving over the front the AC system will at best maintain what you have, or bring it down a few if the inside is scorching hot, it will not cool the inside as it should, the comp is designed to work best at ~ 2000 RPMs, while the vehicle is in motion. But that machine measures the exact amount of freon so if you evac and recharge you should be good, just remember vent temps are not gonna be as good in that shop at idle with no air flow, go for a drive then you will see. And some vehicles have pressure activated fans, they turn on too late to do any good IMO. If you have a chance, with gauges hooked up, wet the cond down with water, watch how much your pressures drop, lower pressure at full charge = colder human. TXVs rarely if ever gives problems, especially with 134A, now the old R12 would turn your system into an acid nightmare with just a small amount of moisture, thank god you don't have to deal with R12 in Florida with all that moisture.
Excellent information 👊🏻👍🏻
Ray - you hit the nail right on the head when you were looking at the temp and pressure chart. Nobody ever figures in the humidity. I am in commercial A/C and the Dewpoint temperature is so important yet nobody talks about that either. That is a real big deal for you in Florida.
Hmmmm, not with respect to just refrigerant pressures. I agree the humidity saps capacity from your system because it is pulling moisture out of the air stream but the refrigerant just "sees" dry bulb temp because its a closed system. Humidity is never on the refrigerant pressure charts.
Noobie question. When you read refrigeration temp charts, how do you account for the way the readings shift as the compressor starts and stops? Do you record cut-in and cut-out readings for both the high and the low side, and compare those four readings to the four readings shown in the graph for the ambient temp?

Just a note, as a Kia technician, at the connectors from the evaporator to the expansion valve through the firewall on the newer vehicles with 1234yf. We find corrosion a lot of times causing a leak so it’s a good idea to pull the expansion valve to see if the evaporators leaking. However I’ve not found it very often on these older optimas with 134
I'm retired but worked on a school fleet in Phoenix when I was a young man and air conditioning was R12. We never evacuated, simply took out the valves and let the freon blast out. R12 was cheap. We just did the repair and filled it a bit and started the vehicle up and kept filling until the pressures looked about right. Those big bottles of R12 were about 30 bucks.

One I can remember was back in '99 or '00 when I was 19, at my first shop. I was doing an oil change on one of those mid 90's Lincolns (with the air suspension switch in the trunk, that you're supposed to shut off before lifting the vehicle).... Well, of course I was in a rush that day and forgot to turn the switch off while doing an EOS. I drained the oil, changed the filter, etc and then realized after letting it back down, the car looked like a lowrider in the back (I'm sure anyone who's dealt with those knows exactly what I'm talking about!).
So, I immediately panicked (and prayed I didn't damage the air bags) and fired the engine up to see if it was alright... It was fine. BUT after about 45 seconds to a minute of watching the thing pump back up, I remembered I didn't put any oil back in it!! I RAN and shut it down, and filled it with oil, and WHEW!! It was ok... That scared the crap out of me though. LoL

Have to admit I'm HIGHLY impressed with the serviceability of the Optima/Sonata late models. Why pull whole service covers when you can have a hand sized hole? The AC components are all within reach. The air filter box isn't buried into the fenderwell. Things are where you'd EXPECT them to be?!! Did they hire a mechanic to be an engineer QA consultant over there? Good on them!
A lot of Hyundais are pretty good with that. There are some exceptions but typically those are more reserved for higher end vehicles like the entire Genesis line Equus/Azera's. Newer cars generally still have some of a splash shield but you only need to take off a couple bolts and a few plastic tabs.
@@AmazingFlyingSquid
More chance for someone to lose the bolts. Or have tabs broken. I much prefer this design. Heck, even have a service hatch or cover of sorts would be good. I know some cars have covers to access fog light at the wheel well.
I felt that until it was Sorento/ Optima(k5)/ telluride, day on the final gen of the optimal, and any Sorento after '15 it seems. The undercovers are brutal especially if you're unprepared, or your impact died. 15 10mm screws in the Sorento and about 8 give or take 10mm in the optima's
@@AmazingFlyingSquid the Azera is no problem. The drain bolt is exposed via an opening in the skid plates and the filter is mounted topside. Can be changed in the driveway. The Genesis however baffles the hell out of me. There IS an access hole for the drain bolt, buuut not the underside mounted filter. And because the skid plate is so encompassing there is no frame access for a standard jack so it requires a lift or recessed bay. The Genesis plate also requires the removal of 17 bolts to remove the plate. Ive owned both 2016 Azera and 2013 Genesis.
Ive actually considered cutting a fold away panel so I can access the filter on the Genesis.

@22:51 - keep in mind, you have the driver side window (and door, if app.) open. So hot air is getting inside the car from the bay. I would close the door and window and let it run for a minute or so for a better reading on the inside temperature.
The gauge is measuring the temp of the air blown in via the center vents, and the specs did say use outside temps to measure against, not recirculated air inside.

I like this. Look how clean is the engine space. No dust, no mud, nothing.
I have often seen that the excellent techs in a shop will always be the ones to freely admit their biggest screw-up. Your Volvo story told me you are one of the good ones. We all have them, and we learned from them. Me personally, to this day, when I do a tire rotation, I do not stop the procedure (no matter what happens around me) until I have rotated all four tires and TIGHTENED all lug nuts on all four wheels (it is either 20 or 25 of them every time).
First, good idea to do the tires all in one process. It's easy to forget when you stop for something else. Second, how can there be 25 lug nuts on a vehicle with 4 tires? Maybe you meant 24?
@@61rampy65 maybe full size spare being rotated in on a 5 lug car?
I had a customer come in for an oil change (that's it) and they came back later that day saying I didn't tighten their lug nuts. bring the car back and the lug nuts are literally stripped half way down the studs. Service manager tried to burry me as the scape goat until I mentioned to him the vehicle history showed brakes were done like 5k miles ago so I didn't even bother to check them and they didn't request a tire rotation so why would I bother taking them off? Furthermore, I explained that the lug nuts were stripped half way down the studs (the threads close to the wheel were gone, almost like the nuts were pulled off the stud, shearing the threads off) and 1, I had no clue how that could have happened, and 2, the vehicle was driving fine. when I pulled it around to give HIM the repair order.
That service manager had the mentality that the customer could do no wrong and regardless what their complaint was, they were right and it was always the technicians fault. we had the highest customer service scores in the area, but the lowest shop morale when he was the manager.
Yep, same here. Basic rotation and oil change and tire work gets done first. Doesn't end till I have wheels torqued. Then I do the oil change. That way when it's on the ground it's on the ground.
Totally different setting, but as a climber I stop talking when I tie in to the rope on the ground. I force myself to finish the procedure before doing or even thinking anything else. I got to witness countless human mistakes as an instructor. The most common scenario was people getting distracted during a critical step ('oh wait let me get my shoes') and then forgetting to pick up where they left off and automatically going into the next step. When they also missed it during the final check I intervened by saying 'hey, you might want to check again'. It usually scared the shit out of them, and there was absolutely no need to for me to patronise. So if you ask me, it doesn't make sense to fire people for making mistakes. Humans make mistakes. The good news is that we learn from them. I'm a big fan of creating an environment where mistakes are shared, analysed and learned from rather than punished. I know a guy who's a programmer, and his boss put up a board to record mistakes, and when it reached a certain number he would buy the whole team cake.
Hey Ray thank you for owning it, world needs more of that. Cheers
I was surprised how much you knew about air air conditioning. I do air conditioning for a living.but just a tip before you do anything with evaluating a charge make sure there are no air flow issues. Eg: cabin filter, blocked condensed, dirty evaporator coil etc. you can solve a lot of problems mostly I checking superheat a lot of people don't do that A superheat reading will tell you so much about the system. Also if you're in the shop block off the condenser make the high side go up and see if the txv adjusts accordingly. Keep up the good job. You have a good channel.
Most auto AC guys know nothing about superheat. Knowing superheat, and watching it as load on the evaporator changes, will usually diagnose a sticking TXV or broken power elrment line in a minute. I too worked commercial/I industrial refrigeration for many years, everything from package units with tin can compressors to 150 ton chillers, factory trained by Carrier back when Syracuse waa still the HQ. Carrier went downhill as soon as UTC bought them out in the '80s to use it as a cash cow.
I'd check the cabin air filter, sometimes there's a restriction of just the fan can do a world of difference for the customer
I have almost zero skills with engines etc... but I really enjoy your videos. and I am learning a lot of stuff! Still going to let a pro work on my car.
What brand is the ratcheting box wrench you used on the expansion valve, Snap on?
Also, the oil change story is a good lesson for young techs. Admitting your failures and not making excuses, that's how you become a good technician.
I’ve asked about those same wrenches on a few of his videos. Still wondering.

@@RainmanRaysRepairs Thanks!
@@RainmanRaysRepairs Did you delete my comments identifying the wrenches? Why?
Well done for owning up ! Only a guy who knows he has much more going for him will find that possible. 6 months ago I started my lawn tractor engine with one screw holding the fan guard down. It turned into a steel discus and slashed the top of the engine cover, ripped out the choke cable and cut a long gash in the battery, spewing acid into me and the concrete..which gassed me.. It finally hit me 1 inch away from crown jewels and cut a gash in my jeans a big graze in my leg.... The cover was folded up and mangled. Lesson learned.. If something isn't FULLY bolted down when you start up, it will blind you and eunuch you and bankrupt you and kill you !
I really love these videos, I love the simple video style with a couple of cuts and images edited in and how its not all flashy with high production value like every single other youtuber out there. Keep up the good work!
I agree. I hate it when other RUclipsrs start with loud music intros and codas. Just get to the show already! I've got many, many channels on a mental list that I refuse to watch any of their videos because of the level of stupid flashy intros and loud music. Then once you do finally get to the show, one minute in, you're met with a pair of commercials, the first one you can't click past it at all, then you have to watch the second commercial for five seconds before you can dismiss it, and again, this is just within the first minute of the video.
I'm a retired tech rep and you sir are the kind of tech I used to enjoy working with. It was a pleasure watching you work and hearing your thought process as you went through the diagnostics.

Thank you for not over-torquing the oil drain plug with an impact! This is very relieving to see lol.
Who TF does that? I have NEVER seen that....EVER.
Mark of a true professional: uses a torque wrench on EVERYTHING... "Click".
it helps with mental exhaustion, actually. eyeballing stuff is torture for a thoughtful person.
Really? I didn't notice that. 🤔

I'm a commercial HVAC installer, service and repair tech.
I like to make sure all vents are open and the filter is on the cleaner side when I'm looking at a service call. Then I like to run the a/c for 10-15 mins at normal outdoor temps. Then I look at the pressures and delta on the system, before I add or leak check system.

A tip that i have when taking those washers off of honda/hyundai/kia vehicles is to use a set of vise grips to grab the washer and then use your wrench/ratchet to unscrew the drain plug from the washer.
Yes, break out the angry pliers.
Yep as a kia tech I do that shit every day
Since 1990, every vehicle I've owned has a Oil Pan Valve installed at the first oil change. Nothing more than common sense and $ 30.
@@walldogger1 I like those valves, too. I use a length of clear vinyl hose to direct the flow from the frame and reduce wind spray.
I lightly clamp the head of the plug in a bench vice then use channel locks to slowly screw off the washer.
I drove a semi for 24yrs, when something or someone distracts you from your normal routine that’s when shit happens.
Kia did a good job protecting the under belly on that model.
The really expensive mistakes are the ones that really, REALLY, stick with you. I had a similar mishap in 1985 with a $23,000+ Circuit board in an Air Data Computer. A supervisor came up while I was working with the unit, wanting to talk, ask questions and generally shoot the breeze while I was working. I was distracted by the conversation and inadvertently swapped a power supply card with an Arithmetic/Logic Unit. All of the connectors were the same, with just a diagonal line on the tops of the cards (I think it was 14 cards in sequence) to differentiate locations. Being distracted, I did not notice my mistake before powering up the unit and watched the card as it smoked in less than 3 seconds. The ALU could not handle the input voltages intended for the power supply card. I wasn't reprimanded or made to pay for it, the supervisor knew that it was his fault for the distraction, but I sweated having to pay for that circuit card for weeks, on an E-3's pay.
To this day, if someone comes up while I'm working, no matter what I'm working on, Cars, small engines, sewing machines, computers, cooking or whatever, I stop all work, wait for them to finish flapping their gums (which it seems is all they ever really want to do), and make sure of where I was at and what I was doing before the interruption while getting back to work. I've gotten to where I can barely tolerate anyone even watching me while I work and will stop until they get a clue and go away. Sometimes I even have to provide the "Clues" or I'd never get anything done.
"Valuable" lessons last a lifetime. Thanks for sharing yours.
But that was on the bus not you we had a similar thing happened with one of our machines that went out to Vegas to a show and they had a throw this thing in a day and it was supposed to say the company one of the things we said was the battery terminal should be different so they cannot cross them they told us just get it to work okay fine not only did it work but it looked awesome 1 of 1 the entire company depends upon its success day two they hooked up the batteries backwards buzz buzz puffs they call us at home on a Sunday to ask how long would it take to build another one you said a day and a half maybe two but we don't have the parts that company is no more but we went into work and took everything all our tools everything before Monday even hit we knew that they were done so we got a ton of stuff out of there fiddled around Monday through Thursday Friday we will call to have a meeting companies closing don't come in Monday here are you a checks then he said go cash him now so they'll clear didn't understand we built the stuff we went and smacked engineers and said that won't work naked so it will repeat up the quality control guy because you took a magic marker and made lines and dots all over the place because the blueprints said if needed but it wouldn't go there physically in the real world that's why it was wired the way it was wired but it was permanent marker that was a different unit going to a customer I brought it to a friend that did airbrushing for cars the coven the lines and dots I had him charge them $5,000 for 1/2 hours work
Some years I learnt to fly gliders. Early lesson was if you get interrupted while doing safety checks you start over.
This is quickly becoming my favorite you tube channel, even if I don’t learn anything new he is definitely entertaining.
Always double check the steps. Sometimes someone who's been working on cars for over 20 years could forget to put the drain plug in and attempt to refill the oil. The guys in the shop will never let me forget that day.
lol done that before
Just happened a few weeks ago, put the drain plug in by hand, got distracted by a customer telling me how to do my job, forgot to use a tool so of course "I wonder where that drip is coming from." Talk about embarrassment. Thankfully we double check every time to look for any potential leaks, hence how I found my mistake, so we didn't send it out the door, but it's not a good feeling when the customer sees the mistake in real time, that's for sure
@@bullypopful I hated that at a shop I used to work at, the customers would be over with you, not every one ofcourse but the odd one that never shut up the whole time. It’s OK to be friendly but hey, I am trying to concentrate on my job. Bad practice, customers should only be in the bay when you are letting them see something.
To avoid the drain plug problem. I made myself a routine where I would never leave a drain plug hand tight, if it was going in it got tightened with the wrench. In and tight or not in at all.
I worked the pit at a quick lube many years ago, we had a kid working topside that started dumping blue water down the oil fill while I had the drain plug out of one we had in the bay

Most air conditioning on vehicles is designed for while driving conditions not parked. I am a refrigeration technician and I believe you just had leaky shrader valves.
Yeah I noticed even in my newer 2018 Camry SE that the heating starts to work well after driving it on the highway.
Love the screw up story.
Sometimes you win, sometimes you learn.
Never lose. 👍🏽😬
Tip. Air over condenser makes a large difference. Put a large fan in front of the vehicle to move air over the condenser. Vehicle condensers become heat soaked with engine heat and don't allow from proper expansion.
When condensers are too hot, or the fans are inop, the high side pressure goes to the moon, if I start to see 250-400 psi I’ll bust out a shop fan
i'm betting the good humor and bubbly personality allows for everyday struggles to be handled with more ease and less stress. this man seems like he handles himself well, handles the job well and can roll with the punches.

I've turned wrenches off and on my entire life, my Dad used to race stock car, blah blah blah. That said, none of us were ever certified (ASE, etc) but listening to you, not just talk, but hold on a lengthy, one-sided conversation with rigs you work on, made me realize something. Now, since most us have held a conversation and ARGUED with a vehicle, I realize, speaking only for myself, that I must actually be a professional, knuckle-dragging mechanic!!! What solidified my thought when you stated that it became personal. Thanks for the videos, learnin and laughing are always fun.
HAHA indeed. I've often talked to parts and vehicles, or referred to something that was uncooperative as "you little bi+ch".
A lot of pros aren't ASE certified either.
I totally ignore people who start yelling at me from a distance. If they want to speak with me, walk up and act like you've got some sense.

I reply with “ I can’t hear you” every time, until they walk up to me to make proper conversation. The person still doesn’t learn.
@@RainmanRaysRepairs Try mouthing the word "I can't hear you" without actually saying anything and see how they react. I worked with a guy who was hard of hearing and I would start talking to him and slowly stop making a sound but would keep moving my mouth. His reaction was hilarious.
good job, really like that you just didnt replace the valve and let the customer see if its alright now. just in case they already have a diagnose from you in the future if the problem keeps coming back. greetings from Germany!
Every good mechanic has that one repair mistake that will give them nightmares for the rest of their life. If they say they've never made a mistake, they're lying.
Hello Ray. Next time you're trying to get the gasket off the drain plug, use channel locks & the ratchet/wrench you used. Grab the gasket with the channel locks, and just unscrew the gasket. Grip hard and should be good to go ~
Was going to mention the same thing. It was painful to watch.
I figured that was the obvious route, but hey, sometimes you do it for the show I guess. I don't do anything without a set of vice grips nearby. It's only detrimental, or a bad idea for those who don't use their brains while using them.
You got to understand that his a general mechanic, nothing special here. He's not fixing BMW's or other German cars that require special techniques and tools and brainstorming to repair them stunning pieces of machinery! lol
My first job was at the corner gas station. On the weekend after mechanics went home for the day. Some time we took in tire jobs and oil changes. Will this guy in a Corvette came in for an oil change. I turned him away said he need to come back when the mechanics were here. It was so low and we had center post lifts it just barely cleared. Well this guy I was working with heard me turn him down. He said I can do it. Well I was pissed and left him to it. At the time gm used two oil filters types / sizes. One had the gasket near the center and one toward the out side. I told him to put the right filter on. He said he knew what to do. This kid was a grandson of the owners best friend. Well he put the wrong filter on filled the oil ran it rechecked the oil and sent the guy on his way. I'm out side pumping gas as this guy backs out and heads to the exit. Soon as he put it in drive and gave it gas oil started pouring out the bottom. I dropped the pump handle and ran him down yelling to turn it off. I hand pushed it back in put the right filter on and refilled it. Saving the motor the station owner money. I told the owner what happened that night but that kid kept working but never changed oil or tires the rest of the time he worked there.
Great story. Everybody screws up and too bad this couldn’t have been a learning experience instead of not letting the guy learn and keep working. Unless he had a bad attitude of course.
I worked at a shop, not sure how many years I worked there at the time but I used to order my own parts. I wasn’t just an oil change jockey, I was doing my apprenticeship and all kinds of work. One day I did a basic service but turned into some kind of extra problems, anyway at the end of it all I forgot to mark down an air filter on my work order sheet and the customer never paid for it. I realized it and told the boss right away, and before they found the mistake. After that I was no longer allowed to order my own parts. It really hurt and I always thought I would have rathered him warn me and say “next time it will come off your pay”, or I would have had no problem paying for the filter that time. People make mistakes - make them accountable but allow them to learn and go forward.
@@peterl2017 Completely agree! Good employees and bad make mistakes. The difference is what they do next. The good ones learn, the bad ones don't...or worse, they lie to cover themselves.
That shop should have just let you be a good employee. Instead, it sounds like the only thing the boss would accept was a cover-up.
I hope you quickly found a place worthy of you.
Just started watching your videos, pretty entertaining and I wish every mechanic would video their work because customers already assume they are going to get scammed before they even go in, this way its all right there. Do you show the customers your video?

When it's affresh washer there is no requirement to crush it any more than you would at the standard torque spec. That's precisely how the last one got so smashed.
Remember, all it has to do is keep the oil in the oil pan. It doesn't have to support the weight of the car.
I dont want no leaks, thats why I make sure its really tight so it wont come off... lol
To be honest....on my vehicles I've never changed the washer /gasket if it isn't cracked. I put a thin coat of silicone sealant on it. Hasn't failed in 20 + years.
Exactly! That torque spec is only 30 ft lbs. It's not a lug nut!
those gaskets also get that crushed when they weren't replaced the last oil change.

Awesome video and dead on suspecting a TXV issue till you noticed the system might be slightly low on refrigerant, 134A is very critical to proper charge to maintain best performance possible. The old r-12 systems were very forgiving on being a little low or a little high. I did find it strange you spent so much time checking and even replaced the core valves but didn't show inspecting or replacing the caps. The cap has a flat seal and are made of thick durable plastic, also the tops of the connections are machined flat and smooth to ensure proper sealing. The cap is the primary seal and the core valve is the secondary. you said you heard a whoosh when you took one of the caps off. This meant it was doing its job and providing a positive seal, core valves are not meant to be a 100% positive seal, they are mainly there to make the system serviceable easily. The main sealing is done with the caps and their rubber seals. Same with a tire valve, the core is secondary seal and the cap is the primary. That is why you should never not replace the caps with ones that are in good condition and have good seals in them. Hope this helps in the future. I always replaced caps and cores in sets to make sure both were in top notch condition.
I remember my worst screw up. I was still pretty green, doing fluid changes and entry level stuff. A customer brought in a 2002 Ford Explorer, yes I remember the exact year of the vehicle, my paycheck went to repairing my screw up. Lube, oil, filter with a trans drain and fill. Someone had stripped the torx drain/fill plug in the trans pan so I had to ease the pan down full. It ended up all over me. Cleaned myself up, cleaned the pan up, new filter, gasket and drain/fill plug, slapped it together and sent it on its way, they made it about three miles and it was towed back. Trans was bone dry. I did get to learn how to pull a trans on a 2002 Ford Explorer the next day. I was lucky enough to not get fired, I made right on the repair with the customer and continued to work and learn at that shop for three more years.

Good work! Glad you put the oil drain plug in the vise.
You reminded me of my first car.. 58 Alfa Gulia Sprint GT. Dad changed out the original racing engine for the smaller one, but somehow or other we ended up with the wrong pan. After that, every time you checked the oil the stick would come up DRY because the pan that was on didn't have oil where the stick was.. I used to freak out gas station guys who would check the oil (1970's!) and kinda panic at the dry stick. I knew that if the oil pressure dipped on a hard turn I needed a quart.
That car almost killed me though, it turns out that the smaller and lighter engine took the car from slightly nose down to slightly nose up. I was surprised one day when I went to change lanes and nothing happened, as if I had no steering. Bad thing at 75 MPH. Dad did teach me not to panic, and I just put the wheel back to center and backed off the throttle a bit, and was rewarded with my front wheels touching the pavement again! The front end was flying!
Loved that car though, I wish I still had it. 5 speed synchro mesh, once rolling I never needed a clutch. :)
I remember reading a comment not too long ago basically stating "never roll down a customer's window."
Thank you, Kia for showing everyone WHY we roll down the windows of our customer's vehicles
I'm retired now, but I ALWAYS rolled down a customer's window. I had 2 cars, early in my career, that I heard the dressed "chunk!" Of the power locks engaged when I shut the door, then waiting on a lock smith to come to the shop I worked at to unlock the door. I have a set of door opening tools, but the shop wanted a bonded locksmith to do it in case of damage, it'd be his problem, not ours
Polish guy called the dealer where he just bought a new car and asked, "What is the cheapest window on this car to break?" Dealer asked the guy why wanted to break a window on his brand new ride, and the Polish guy replied that he locked the keys inside the car. The dealer informed his customer that there was no need to break a window, he'd send a lot boy with a duplicate key. The Polish guy said, "OK, but hurry up. It's going to rain and I want to put the top up."
Yup. I always roll down a window in every car I pull in. I had one up on jackstands, in Drive, to check front wheel bearings. I got out to go listen at the wheels and the door shut behind me. When the wheels got to 9mphi heard the doors lock. Uh oh...had to call the customer for their spare key. After that every car gets the window rolled down. I'll risk having to repair a window once in a while as opposed to having keys locked inside again.
Have you ever been blamed if the window wouldn't roll back up?
@@henrydillard6217 Nope. Not yet. When/if that happens will deal with it.
back in trade school, AC diag was by far my weakest class. I just couldn't wrap my head around the pressures and what the readings indicated what was wrong. The only thing I did store in memory was if both sides read low, the most likely issue was a low charge and since its a closed loop system, there had to be a leak. Somehow, when watching this video I saw the readings and immediately knew they were low but couldn't for the life of me remember what it should have been reading XD
High side should be about 2.2x ambient temp. Low side 20-40ish. If the low is high and the high is low @ idle then gets better if revved the compressor is weak. Pumps better @ faster speed.
Really interesting to see what a modern mechanic has to deal with these days, warts n all.
Oil should always be added to the new filter when replaced. It even has pictures on the side of the filters of some manufacturers. It helps lessen the time the engine bearings will be spinning with no oil pressure.(this is important). If you feel uncomfortable adding new oil to the filter in the large center hole, mount the filter upright on the bench and add it to the outer holes so it will be prefiltered. It will take a little longer but it also takes time to drain the oil.
Because I have weak arms( Muscular Dystrophy) I cheat by only half filling the Class 8 Diesel filters, but I prefill the filters.
My Dad was a licensed old school mechanic born in 1902...and he added oil to his filters.
Like your work Ray and I think you do a great job of filming your work

I do all my own mechanical work. But if this guy was my local mech6, I'd take it to him.
Trustworthy guy
That looks like a 2011 or newer Kia Optima? I'm pretty sure that compressor has no clutch but, instead, has the solenoid valve in the back of it that likes to stick. The PCM regulates the compressor with by pulse width modulating that solenoid. I've seen them stick many times. Do a tappy tap tap on the compressor near that valve and see if it improves. That will also cause the intermittent issue they complain of and the pressures you noted.
typical fixing shit that aint broke actually breaks it
@@TheGuruStud I just had a 2015 Corolla come in with this very problem. AC was intermittent. I finally got it to fail and while it wasn't working I tapped on the compressor near the solenoid. It immediately started working. Replaced the compressor. Nobody likes an expensive repair but they were very happy it was fixed. All these style compressors with the control valve instead of a clutch are prone to this type of failure. If the solenoid valve is sold separately you can just replace it. In most cases, it's not sold separately and you have to buy a compressor.
No newer than ‘14 based on the engine bay
I’ve had several of these optimas have this issue, all because of the compressor.
I have a 2014 Sonata that had a/c issues. Ice cold going down the road but come to a stop and idle it would barely blow cool at times. I replaced the solenoid in the compressor after about a year of owning the vehicle ( bought used in 2019). It ran a LOT better at idle but still not like I thought it should. I finally got around to replacing the TXR / Expansion valve about 2 / 3 weeks ago. Now it will get cold at idle without having to ramp up the RPM's and even colder going down the road than I thought possible. I know of a couple of other people that have the same vehicle with same issues and it's one of the other that has fixed it. No need for a new compressor which some shops will try to get you on.
A long long time ago, it was an automatic "lick" from the paddle if the old shop teacher found a loose drain plug. Either leave it out or tighten it, never leave it loose, that was his rule and he didn't kid around when he swung the paddle.

@@doji_town_adventures and that's the problem with the world today. Some people just need a kick in the ass to get things right. The problem is, it's illegal to give them that kick in the ass.

If there are no consequences then you didn't do anything wrong.
A paddling is a little of the chart, but if someone really wants to do their job properly they will accept it. Because in a few hours when that engine blows up because it doesn't have any oil, guess who doesn't have a job anymore.

Only did this twice in 50 years. Had gushers coming out of the flange of the filter housing. Mess was nasty. But no damage - other than to my pride. 2nd time I thought I checked - did not check well enough. Have not done it a 3rd time - yet.
Pretty cool of you to recount your mistakes. Nobody is perfect.
Do you have a good relationship with other people at your shop? I'm curious about the environment of an auto shop.

I left a breaker bar on the crank bolt by getting rushed and turned the engine over and broke the timing chain on a customers car once. Lesson learned, dont let people rush you.

I got lucky, the wrench came of by itself on the impact.
When my service writers rush me I tell them "it will be done when im finished, if you want it done faster then it's not my fault and I better get paid if it cones back."
It's a good thing your learning experience involved a non-interference engine. Otherwise it would have been much much worse lol

quick tip i've found with stuck crush washers, just use some side cutters and cut it in either one or two places and it'll come right off
Owwww, I hit my head when you dropped me, Reeeeeeee!
I grab the washer with plier and spin the drain plug off
yeah, that works well sometimes.
I love how you torque those bolts down with a verbal “CLICK”
Doodle ooddle ooh
I used to do auto AC work...mostly when R-12 was still the 'main coolant' in use. Most-all cars had the identical diagnosis...low-high, high-low readings, you'd replace the TXV, vacuum and recharge. Still a problem? You'd replace the dryer...going with the idea that 'it was plugged' (and that the TXV was now 'good', regardless). Blockages caused the 'opposite readings', in most-cases...but that was when compressors were either working, or they weren't...no real middle ground back then. Good thing was, it was fairly expected to get 35-38-F vent temps, on a good system, too. (I've seen frost blow out of vents in the summer, on Cadillacs back then)
