Hey Scotty!
I drive a GMC Jimmy 2000, my AC is slowly spinning this same way---how much do you think that'd cost to replace?
Scotty Kilmer many times ask questions but you didn’t reply 😐
I want to remove Hyundai Sonata compressor how to close the gas from going to the air ?
How do I know if it's the compressor and not the pressure switch? Is that something I have to get a mechanic to diagnose? My 07 outlander will blow cold at first, but then quit after a while.. and then I can re-set a while after that... but living in South FL doesn't help the situation
excuse me you have a link for the other items but i cant seem to find a place to buy number 8.

It’s nice to see someone who knows how to make a “how to” video. 4 minutes is all it took. I can’t stand when people make a 30 minute video filled with useless talking and over explaining and all the story telling. Drives me nuts
Yeah well he's been on TV etc for over 20 years so it comes with experience. I totally agree.
useless talking and story telling is what gets me.......
the man knows his audience!
Usual videos:
"Ok so first I'm gonna reach under the dash and pull the hood release. Theres a cable running to the hood latch and when I pull it the latch opens. Now I'm going to open the hood and use this handy hood prop to prop it up so it don't fall on my head....Now this right here is what I call a wrench, its used to turn bolts..."
Amen I hate trying to get a quick tip and searching through long videos to find the 10 sec I needed.
Scotty's video editing make things look soo easy but in reality it's pain in the ass to get the job done.
Murphys law loves to hang out with cars lol.
I'll take a pain in the ass over paying someone $400.00 or more to install it for me.
Word Unheard I'd pay 400 easy. Shop quoted me 1300 for this job.
I agree wrenched on cars until I turned 40 sold all my old cars now all I have is new cars I replace them every 5 years no more wrenching let the dealer wrench on it.
Blastman8888, then wrenching wasn't in your blood. I'm 62 and enjoy wrenching on my ole Nissan. Keeps the mind and body active.
Scotty, I run to you whenever I hear, see, smell or feel something's wrong. Thank you. I like knowing before going to a mechanic. You are a true friend in my head.
W
Now THESE are the Scotty Kilmer videos I liked!
Thank you for showing me why it was a good move to take my car to the mechanic.
Its always easiest to take it to the mechanic,once you learn if u want to learn u will put the money in the pocket and its not rocket science
@@KN-mi7mh But you need the tools. One of the biggest reasons why people don't like fixing their own cars is that they'll run into a problem that wasn't expected, and they get stuck.
@@znhait true u right
@@znhait Yeah this all looks like something i could do if it weren't for the step of purging the refigerent before starting anything else. I can get a vaccuum pump and gages for 100 bucks, but a machine to remove refrigerant? That's another ballgame.
@@jackburton2680 except you can always take it to a mech to purge the refrigerant out, and do the rest yourself, saves money in the long run… but I know money isn’t a problem for many
I enjoy working on my cars so going to a mech for the purging is all I would do
scotty you literally have the best auto tutorials online. quick and to the point. thank you
You have to vacuum the system any time it's opened to the air, as air in the system will wreck the pressure whether it has moisture in it or not.
This is hands down, the best DIY AC compressor replacement video on RUclips!
compressor clutches only need positive power to run, and negative ground to ground the clutch so it works. Other wires are sensor wires, you can normally just bypass them. Or, if you don't want to do that, get the correctly made replacement one, you got a cheaply built one, see that a lot with the chinese made ones.
depends on what was wrong originally. Of course replacing all the parts will always work, but that may be wasting money. I'd try the compressor, the drier, and the expansion valve myself.
Hi scotty I just want to let you know watching your videos has help me with more than one repair on my truck and I am now a fan and appreciate what you do...
Thank you for your video. I wasn't sure if I should add the oil to the compressor before or after it was vacuumed out. I installed one incorrectly 3 years ago and am hoping to do it the right way this time
Hey Scotty. Thanks so much for your AC videos. My compressor was leaking oil and I did the replacement last weekend all by myself. Since it's an old car, I replaced the receiver drier and all the o-ring seals on the lines to make sure nothing else goes wrong in the near future. I used those 12 oz cans of refrigerant instead of that big tank you have, and a small digital kitchen scale for measurement.
you can use them on orifice tube systems as most american cars have, but they tend to clog up expansion valve systems
Great video, Scotty. I just had my ac compressor burn out. There was smoke coming from the engine on the passenger side and through the air vents. Took it to firestone. The original compressor had a lot of charred stuff coming out from the sides and the pulley wouldn't turn. They put in a new one. They did everything you mentioned that needed to be repaired or replaced to make it functional again. A friend suggested a pulley kit to attach to the alternator and crank shaft. Decided to repair it all at once. I would've eventually had to add that ac compressor back, summer is a coming. Took over 4 hours. All good. Cost just under $1000. Drove car, 1996 toyota camry LE with a v6 engine, home. That was about a one hundred mile trip. Worked great. Wish I was closer to home to try to get help from a neighbor to replace it.
you use pag oil, and put in maybe 4 or 5 ounces, depending upon the vehicle. See your maker's suggestion at ac oil amount and use that
@StephanieP3 many things can go wrong, try hot wiring the compressor directly from the battery with a jumper, if it doesn't work then, could be a bad compressor. Scotty
THANK YOU SO MUCH! I LIVE IN SOUTH TEXAS AND YOU SHOWED ME HOW TO FIX IT MYSELF!!!!
Scott. I am a hug fan of your videos. You are the man. Thanks.
i wish you were my neighbor... 😢
+Ivan Chavez Me too; he would get fat around me. I would be feeding him so many homemade pastries that he would wobble when he walked. His neighbors are blessed; having a know all guy next door.
He'd be revving stuff up, yelling IM SCOTTY KILMER every other day and there would be tons of cars parked on the street.
Raylan Givens lmfaoooo
LOL I love Scotty he's the real McCoy!
@@MrPavePaws 😂😂😂 ✌️✌️✌️
Scotty, You are the coolest Mechanic I know!!! Thank you for all the vids, you are teaching great mechanics!
I just love how hes yelling all that info into my ear.
if it won't spin when power goes to it, compressor clutch is shot. we mechanics only replace entire compressors though, cause when clutches go out the compressor itself is generally pretty well shot too
often a bad blower motor resistor assembly, try that first. If you like my car help, be sure to watch my live car talk show every saturday morning at 10 AM CST on google events.

pag oil, all auto parts stores sell em. But prices vary widely from 60 to 250 bucks plus parts for that work, call around in your area.

Thanks Scotty this video helped me alot.You can rent the vacume pump at most Autozones as a loaner tool for the job.
I'm a single mom of 4. So paying someone to replace my compressor would have put a big dent in my budget. Thanks to this video I was able to do it myself
@kd25510 cause the inside drives the compressor, the outside only is driven by the pulley. the inside only works when it gets electrical power. Scotty
Got to tell you Scotty, you're one of the best! :-)

@@scottykilmer do you poor the oil in the low side or high side?
your video just saved me $900. the mechanic wanted 600 for the compressor, $100/lb for R12 (my car takes 3lbs 4oz). plus labor and checking for leaks. i found a remanufactured compressor for 200, no cost for R12 bc my uncle had it, and it was $100 for tools (manifold gauges, etc). all together every thing cost me about $300. If i am ever down by you in Houston, i owe you a drink
Scotty is the Yoda of Mechanics makes it look really easy 👍😎
Edmund Herrera but it's not that easy,
@MisterrJOVI tons of things can do that, low refrigerant, bad ac clutch coil, ac electrical problems. So try hot wiring the clutch to see if it works first.
depends on how fast you are. i could do it in less than an hour
depends on many things, temp, humidity, but at idle with a fan blowing in front of the car, low shold be 35 or so and high around 200
My ac is blowing hot air. I was hoping it was something minor, but unfortunately i need a new compressor. but luckily i still have warranty on my car... so carmax is ordering my part and fixing it for me.. with a $250 deductible. 😰 you make it look easy!
ash G - People who are doing what they love doing always will.
I watched these videos and got an idea what I was in for. Today I changed my compressor and charged the system. 41 degrees! Thanks, Scotty
How the hell did you get that much info across in a video less than 4 minutes?
Scotty, thank you because of this video i got my ac fixed and saved me a lot.
Scotty Kilmer is awesome. I've learned a lot from this guy.
@PVoyager change the belt first, if it still does it, see if it's the tensioner slipping, Or a bad clutch. But me, I never change ac clutches anymore, just the whole compressor as they are normally badly worn with the clutch and changing just the clutch is a band aid waste over time. Scotty
@scottykilmer harder then the chevy below, but not that bad once you access the bolts to remove it, I often do it from below after jacking it up. Scotty
Hey there Scotty! I recently had to replace the AC Compressor and Drier in my '02 Avalanche (It gets a bit hot here in Oklahoma during the summer) and without your videos and advice, I would have been stuck paying some mechanic shop easily triple what it put into the job - and I get to keep the tools for future use! I got the compressor from a place on ebay for about $150, orifice tube, drier, high pressure valve for about $50 online, vacuum pump and gauges at Harbor Freight (some people complain, but I haven't had a tool break from there yet) for $150, and r134 from Autozone for $20. I learned a lot in the process - a buddy of mine does home AC so he recovered the old refrigerant for a case of beer!
Anyway, just wanted to give you a big THANKS for the advice and instruction. AIRBORNE!!!!

an internal restriction in the system often does that, like a bad expansion valve or clogged condenser
@MyCoolAimName1 I used to on CBS, but they ran out of money. I now do it here, and am much happier. I can tell the total truth here. Scotty
Just replaced the compressor and accumulator/Dryer in my wife's 2006 Saturn Vue with your expert advice! It's now blowing ICE COLD again, and my wife isn't yelling at me anymore that she's HOT! Saved a ton of money, thanks for the great video Scotty, you are the man!
it will do that itself when you startt it up, but many guys will rotate it a few times before starting it up
@aftoyboy your guess is as good as mine. You need a dealer level diagram of those hoses, try to get a dealer parts department to print you one out. I don't even have such info in my data base.
depends on the car, and what the mechanic decides to charge. Price around, as it varies widely from car to car, and place to place.
not sure why anyone would give a thumbs down-- this is a very informative 'overview' video to gain the understanding required to do the job!
@killshotnation yes, they hide them everywhere. BUT they are all on the low side hose, so go to the compressor, follow the thicker low side hose back to the firewall, and somewhere there will be the low pressure switch. BUT, you may really mean the high pressure switch, which is on the high pressure line, so follow the thin line for that. Scotty
@jessisherriff you can try seals, but it's one hell of a job, most guys change the whole compressor. And anyway, if the seals are worn, so is the rest of the compressor.. Scotty
@BAWLS2894 they all used to, and most still do. But some really fancy new ones don't use clutches and run all the time. Scotty
Hey Scotty! I have a 2012 Scion xB with over 168,000 miles on it. I bought a new A/C Compressor Kit from AutoZone for around $430.00 because my current compressor is blowing hot air and no longer works after getting 2 opinions one from the original dealer that I bought the car from and at a Firestone Complete Auto Care shop. I have already gotten taken to the cleaners once at the Firestone Complete Auto Care near my home. I had the radiator cooling fans replaced for a bill of over $1,200!!! I asked the Firestone place what they would charge for the labor if I bought the AC Compressor Kit from Autozone and if I provide the parts. Firestone said that they would allow me to provide the kit for them to install. They said I have to buy the compressor from them. Firestone would have charged me over $2,000!!! for the parts and labor. I tried to lookup these mobile mechanic websites online to see if they provide reasonable rates if I provided the parts. But they wold have charged me over $1,000 labor even with parts. I called a local independent repair shop not too far away from the same Firestone place that charged me over $1,200 for the new radiator cooling fans and quoted me over $2,000 to replace the ac compressor. I called this place. They called me back and they quoted me an estimate over $1,400 for labor with me providing the parts!!!!!! I am so frustrated because I have already gotten ripped off once with the radiator cooling fans. I do not want to get ripped off now with my ac compressor problem. I am not an auto mechanic and I am not an expert on cars. I just want to know how I can find a good auto mechanic or shop that doesn't overcharge for labor and overhead and everything! I have seen a couple of your videos on how to avoid getting ripped off by certain chains and pop-and-son's auto shops, But I cannot seem to find a mechanic that offers reasonable rates just to install a new ac compressor that I bought new to provide for them. I don't know who I can turn to. Help!!!! Sincerely, Daniel Willis from Homestead, Florida. Thanks Scotty.
@214truema generally not enough room to do it, If you can remove it and the hoses give you enough room to access the clutch bolts and clips, yes, but it's iffy on that honda. Scotty
Thanks for all the wonderful videos. Had my 97 Hyundai Tiberon in the fam since 32 miles. I have had it the past 11 years and reached 192,000 miles. Just got quoted $1200 for a new compressor. After dropping 2gs the past 2 months this has me scratching my head if I want to continue my love affair with this car 😂😂. Called around and got a $775 price on one so may have to invest one last pricey part. I'm gonna keep watching your vids so one day I have the balls to actually fix something myself lol. Keep putting these awsome vids out. Thanks again✌🏾
@BAWLS2894 you got it, make sure the belt isn't loose though, that can make weird noises too. But if it's tight, comps going out. Scotty
That was the quickest and easiest a.c. compressor change I've ever seen.So easy.lol
Final question (hopefully), as it's not making any noise and it does have lube in the system, do you think it's safe to run it for a bit and see if it does "loosen" up?
I have to say although I'm in the UK & you're in the USA I'm so glad of your help, you're so quick to answer! God bless, Bill. It's a great site!
worth a try.
you have to find the exact leak point, use soapy water and it will buggle from the leak area. see if it's the hose, the gasket, or the compressor, could be any
find if it's radiator coolant or ac refrigerant coolant. Fix whatever is leaking, and if it's coolant, it's obvious as the radiator will be empty when you take the cap off
You are in the top 10 percent mechanics worldwide online, I have ever seen.
you can add oil to a noisy compressor and pray. if a compressor comes with oil, it needs no more. And you can turn the compressor after it's put on the car
small knocks like that are often worn transmission or motor mounts, check that first. As for ac, tons of things can do that, start by checking the refrigerant level and PRAY it's just low on gas.
either blower motor is wearing out, or kleenxes or stuff are jammed into the intake slowing speed
to get a correct hose, they have to be described to the seller. They are all Ac hoses, and you say "the ac hose from the compressor to the condenser" if it's that hose. Or the drier to the evaporator hose. Wherever the hose goes, you describe it.
Thanks Scotty. I must say you are the most helpful person on RUclips. I have one last question. I'm changing out my compressor in a 2006 Saturn Ion. The Drier is on the Condenser and cannot be removed. Should I replace the Condenser? The manual only talks about replacing the refrigerant filter when changing out a major component.
A fellow Screaming Eagle, I knew there was a reason I liked ya.
This Guy he always know His stuf. Hey Scotty, i think ALL mechanics hate you for teaching people how to do the work and save $$$$. Great video.....AGAIN
@lowlow643 Electrical problems can be cows to fix. Me, I'd just hot wire the compressor, and it that works, I'd do it permanently with a toggle switch and wire from the battery positive to the ac clutch. Scotty
it may fit, look at the numbers on the compressor, clean off the grease, if they are the same model it would work.
@MrVincent026 they use various models, they all have numbers and letters on them though. Read them off your old one. Scotty
@ampecsu yes, but I don't advise junk yard compressors, big gambl.e
@RastaMan699 sure, try hot wiring it direct from the battery to see. If so, fix it, or run a toggle switch from the dash to it to run it on manually., Scotty
there are certain amounts of oil to put in ac compressors, and that information should be obtained before putting a new compressor on. but the process is exactly as I show to change one out > ONLY if the old one blew and threw metal inside the system, you would have to flush it out, change the expansion valve, the drier, and the condenser to make sure it would not break again.
@Outdatedcrab1 yes, no one really fixes em, as that's just a band aid and the whole thing's breaking down anyway. Scotty
Thanks for making this easier to understand! My Saturn Vue -03 a/c stopped blowing cold 3 weeks ago. I toughed it out, then mother nature heated things up. Took it to a shop, was told the uv dye shows compressor leaking - they can't add Freon - ozone layer contamination, etc. They say replace compressor - what do u think? My money tree is suffering from heat exhaustion n $800 bucks seems pricey
@imabichover9000 could be a leaking evaporator hiding back there. YOu can't see it, so have a mechanic use his sniffer machine and a little refrigerant in the system to see if the leak's there. Scotty
back expansion valve may be bad, opening and closing AC systems can break them in older vehicles
This men is a Legend!!!
Haha, you make it look easy and fun. You're like the Steve Irwin of car repair. I love the little refrigerant scale in a suitcase.
Sounds like Charlie Day is instructing me in replacing my compressor. Excellent video.
Scotty,
2006 Chrysler 300 3.5 RWD.
Filled coolant last year.
Now blows hot.
Added AC Pro and it's now cold again but hear no audible leak although I don't think I filled it to max with refrigerant so the pressure might not be strong enough.
Any advice on locating-diagnosing leak?
Thank you in advance.
Your videos are priceless and you present in a clear and charismatic manner that is greatly appreciated
Never stop being awesome!
johnnymac1975 put UV leak dye into the system and check for the green leaks. OR, buy a 100 dollar sniffing machine that smells out AC leaks, you can get em online easily
i love all the AutoZone oil you have in the background
well, that MG relay is what you're looking for, and it should be in that spot. On all the ones I ever worked on it was under the hood in the main fuse and relay box
@jhep1985 It's the law in most places, the tank is just the storage tank for the recovery machine. all mechanics have to own them by law if they work on Ac systems. Scotty
often a wearing out compressor does that, but check the system for low refrigerant and a loose or worn Ac belt and PRAY it's that.
Thank you Mr. Kilmer. I appreciate that. In the desert and the ac was just serviced, and now its either blown compressor? Or clutch bearing seized? But no doubt sloppy workmanship, as ac worked great for 22 plus years....Thanks again
Scotty , hey first off thanks for the videos they are truly helpful.
My car started blowing hot air while driving to work then a real funky smell started to come through the vents. Like a burnt rubber type of smell. I took it to a mechanic for a visual check and my fan clutch was not kicking on. He told me I need a new compressor. Any input would be helpful. Thanks
@jessisherriff when the seals go bad on the compressor, it spews out and needs replacing. Scotty
We just replace the radiator on our 02 Venture. It ran fine for about two days, then when we started it, it said "POOM" and started spewing coolant. We aren't car pros by any means, but are trying to do as much as possible to save money. It's spewing from an area on the lower passenger side of the engine, on what I believe is the compressor? It's a brass piece that looks a bit like a hex bolt with a hole in the top. Maybe an air pressure issue?
saturns have high priced compressors, just the way it is. But heck, get an add kit at auto zone or somewhere, and add it yourself, each can is like 8 bucks.

you must evacuate the system first, then fill it up with a factory load of refrigerant.Start there, but it it won't take refrigerant . try hot wiring the compressor clutch with power from the battery to get it start sucking
simple job, no video yet though. You loosen the bolts on the adjuster and swing it down to get the belt off. Most have an adjuster with a screw assembly that loosens and tightens the belt
often a restriction in the system will do that. Hook up AC gauges to low and high side, e mail me the readings
stopping and going is often just being low in refrigerant. Check that first.
hondas have pretty weak compressors that often just go bad. Pray it's just that and not something else like a bad condenser
@Tynlinz if it runs fine and cools fine, why not just run a toggle switch from the battery to the compressor with a 20 amps inline fuse? makes it easier than finding shorts.
could mean lots of things, but check the refrigerant level first and pray it's just that.
