I've spun wrenches on and off over the past 60 years and here I am, 75, snowed in, and I find your channel. I've been watching every day and I have to say I really enjoy your work, your fine attitude, your skills and integrity! My wife cannot for the life of her get why I can sit and watch you work for hours. It takes me back to a better time. Best of luck to you!!!
Unless our wives work with us on our projects, there isn't any way they'd understand! I too enjoy every video and have learned to work more methodically! I do 97.3% of our own work on our vehicles. My newest vehicle is a 2003 Subaru Forester just nearing 200,000 miles. Just replaced the head gaskets because I got tired of smelling oil burning on the exhaust!
That kind of reminds me of my grandpa, my dad and his 3 brothers. It's just my dad and his oldest brother left now and my dad will be 60 next year. My grandpa collected cars for most of his life and worked on them as a hobby and my dad and uncles all grew up fiddling with them. He still had hundreds of cars still up there when he passed (it was extremely sad when he started to give up working on them - he quit playing guitar around the same time - too shaky and weak for both) - but the cars ranged from maybe the early 30's to the mid 70's - my dad inherited them all. The auto mechanic gene about halfway skipped me (my dad and I have about equal patience levels so even though we'd watch and help him, he's the "I'll do it myself" type and can't stand to just watch someone else work - plus I was scared to death to dig into a car and mess it up - even though he could have easily fixed it - I did get a 64 1/2 Mustang from my grandpa and that's where I learned what I _do_ know) - but I'm pretty mechanically inclined in pretty much everything else and I could get a vehicle going but it's like my dad is a brain surgeon and I'm just trained in first aid. Sorry for such a long comment but anything about cars/mechanic work, guitars, semi trucks, logging or farming and I immediately think about my dad, my grandpa and my family. And my grandpa just passed back in September so that wound is barely scabbed over. He definitely had a young man's heart and mind in an old man's body.
Well done Ray! Most of us would have fired parts cannons at the misfires and the EVAP purge solenoid. But we would have been disappointed. You sir are a master troubleshooter!
I have a 2000 Silverado and replaced the ECM about 4 months ago. I ordered it online and gave them my VIN. It showed up a few days later already programmed. All I had to do is do a key relearn which is done with the truck, no computer. Works great.
I am impressed with your knowledge. I don't know how many years you have been working on cars or what educational opportunities you have availed yourself of. That said, it seems to me that your knowledge is incredibly diverse, covering so many different cars. Very impressive. I am a 79 year old man who started his mechanical career back around 1958 or so by opening up a flat head ford and doing some simple fixing. I have done a lot of car repair and I am impressed with your knowledge. Well done!
@@juanawashington9940 That's why the scan tool has become the mechanic's best friend. if used well, it makes even today's repairs so much more straightforward.
@@martinaudet7687 I had just bought a 3rd new scan tool, INNOVA 5610 which is a great tool..... then I bought an '02 Ford 7.3L diesel Excursion, and find that it does not read every thing that it should ..... darn it. needs a special protocol for Ford diesel engines
Replacing parts isn't the gem of auto repair work. It's the ability to troubleshoot the problem and replace the correct part(s). Troubleshooting should be the main focus in teaching auto repair.

You show things I didn't get to do with my Fluke meter. It would have been nice, back In the day, to even get authorized for the first hour of diagnosis according to state guidelines. Things took longer and they would try to speculate. The real right testing would occur, but after the guess was tried. Manuals were problematic also. You're lucky. Count your blessings, my friend. You show real qualities that are to be aspired to.
Hey Rainman my name is Brandon, im a young student in Missouri and im in a auto-mechanics class. Your videos are really inspiring and show me what its like to be in the shop and also give great tips i have watched a lot of your videos and there actually humorous i just want to thank you for the great content and keep up the great work!
I know I have posted before how much I appreciate you be a diagnostichian! Love that you check and confirm failure of components rather than the " parts cannon" good job Ray.
Amazing! You work efficiently while recording--edit and put out videos daily--have a family (I believe)--watch other mechanics' videos--and read comments too. "I'll have what your having" (quote from an old movie)

11:38 They aren't always identical there's quite a few parts for my K2500 where the AC and GM part numbers are significantly different. Maybe they've changed that in the past 22 years but since they still sell OEM parts from that era they keep the two line label. Great video!
and people wonder why some of these issues are so difficult to figure out....just because you have a scan tool , it doesn't pinpoint the exact problem....that's why when an auto parts store scans your codes, they end up selling you 6 parts when it may only be one or two.....this stuff is like surgery on an electrical level....if only people knew
Damn.. There's nothing quite like the feeling of fixing something - everything from a cellphone to a computer to vehicles to heavy equipment to a house and everything in between. And it adds to the feeling whenever whatever you're fixing would be totally shot without a fix.
sweet! If I recall, you went through this with them once before about a year ago, where the service never called you back and you had to call them again the next day. It seem they are not very assistive to your needs as a paid service. "Click!"

RAY!!!! Thank you so so much. I am 16 and I have been trying to find out why my dads 03 express van was having this problem. I couldn't find it anywhere. It has been having this problem ever since I replaced the crankshaft position sensor. This helped me so much Ray. Thank you!!
Being a Master tech ( currently retired ) all I can say is great job with diag. and repair procedure ! I always said COVER YOUR ASS. Andyou did down to perfection !
I learned something today! It's a good day! I didn't know that the ECM in a vehicle had to go through that to be replaced. Thanks for taking us through that procedure. And, as always, your excellent diagnostic procedures...a pleasure to watch.
Thank you Ray for your integrity and accurate diagnosis. I am a big fan of SMA also. Are you at liberty to say what other technicians on You Tube you value and appreciate? Anyone else in New York State that I could utilize?
Heavy Duty, Over the Road Trucking going computerized on their engines made me retire after 35 years. I couldn't keep up with technology. I could rebuild and repair anything our company had.

This episode reminded me of dealing with verizons completely incompetent remote network engineers when installing cellular internet backups. Every single time, the unit that they were supposed to preconfigure arrives totally unconfigured, and when you finally get them on the phone and remoted in after a godam hour, they can't even log in to the thing, just sit there guessing passwords for an hour refusing to escalate, when if they woul've just given me credentials i could've had the thing installed in 30 minutes.
It's obvious Ray has a next level intelligence with car diagnosis and repair or maintenance. It's a natural gift. No amount of education or experience can put anyone to this level. Maybe talking to the camera is massively improving his skills level.🤣 It's amazing how you are knowledgeable in both mechanical and electrical diagnostic techniques and maintenance.

Trouble shooting par excellence Ray. You are the man, never taking what is read as gospel. Most people would be ripping out fuel injectors etc to fix problems.But you with your vast experience know to look elsewhere first.excellent first class 👍. Oh,that reminds me to remind you to have a great day 🇬🇷😃👍
I swear that person you first talked to is the same one months ago. She flaked out on you that time as well, leaving you waiting around after hours, and on a Friday as I remember. Absolutely brilliant customer service.
As an old shade tree mechanic, one of the things watching this channel has amazed me is that although I know that codes are stored to tell you what's happened, I didn't know that with the right scan tool you could activate/deactivate subsystems all over the car. Having to call and make an appointment to install a new computer is startling. There is still a lot of basic wrench turning that goes on, but wow, I'm never attempting to work on a modern car except to change the oil or maybe do brakes.
I can buy a small battery operated computer that can talk using satellites in orbit for a few hundred. But one to talk to my truck is a couple thousand and the wiring diagram is extra. What a rip off.
@@michaelvangundy226 It's because most car manufacturers are using 20+ year outdated technology for their car computers, even today. This is also why the chip shortage is such a big deal. Because the semiconductor companies can't deal with manufacturing 20+ year old parts (which require a different process) when they are so behind on MODERN parts. Plus keeping production lines for such old hardware is expensive. (Consequently this is also why Tesla is not affected by the chip shortage nearly as much, because they use modern stuff.)
@@StormsparkPegasus What you say is indeed true, however Tesla is going to find that theit new design Chips are going obsolete faster than ever. One example I can see rearing its ugly head in the not too distant future is the displays used on Tesla's will almost certainly go obsolete in the next 3 to 6 Years, especially if your Tesla is already 3 years old.
Paint works well 😌 lol. That's exactly how I would fix e vap system done it many times. The programming ppl seem to be God on this video 📹. Lack of rot is making me want to move lol . 😆 Be safe and have a great day.
Only Fords require 2 keys from what I've seen. :) Nice work as usual Ray. I'll bet the solenoid shorted and took out the driver, but I suppose the order of failure isn't really of important. What matters is it's fixed.
So glad I live in southern Arizona. It would take 100 years for a vehicle in Arizona to turn into a rustbucket like 10 year old vehicles in Florida. Of course, the plastic parts on vehicles here are pretty well shot in 20 years from the intense UV light.
Programming/reprogramming ECMs is such an interesting process. It's like you've used 2 very different skill sets. [and it 'solved'/resolved the misfire issues]
Ignition is handled a similar fashion. The ECM maintains ground on the coil (iirc) and disconnects the ground to cause a spark to fire across the plug. The fried ground circuit was probably preventing the ECM from being able to disconnect the ignition grounds properly, or could have been preventing the ECM from grounding the injectors to fire. (The ECM uses ground instead of the +12v line to control a lot of stuff.) Either way, the result was the same. And the failed evap valve was the clue to find the culprit of it all. Ray actually made it a point to make sure the ECM was bad, which is great.
in my industry they were plagued with damaged pins when seating connectors. As such, they REQUIRED an inhouse certification called mate/demate. It was a frequent retraining lasting 4 hours. One simple and essential element was: visually inspect both connector halves before mating. I still do this for any of my electronics.... Cars too!!
My first reaction to that RAP (remote assisted programming) tool experience was when do you ask for a refund and send it back! I presume it's the lesser of evils working in a shop that takes all makes as yours does tho, as otherwise you'd have to have dozens of different programming tools. I prefer complete control of the job end to end, so I'm glad I only focus on GM brand module programming to do it myself seeing that _remote_ experience you had there. ;-) BTW, those ACDelco and GM part numbers are not always the same. They are the same for parts only GM sells from the dealer, but anything ACDelco also sells retail will have their own unique ACD number in that field.
Everything you did today is beyond my reach I was taught back in the 70s about automobiles and now that automobiles have all these computers and all these sensors to be quite honest Ray this crap scares the 💩out of me. Ray can you recommend a school or somewhere I can teach myself that information? God bless your boss you’re the man✝️✝️✝️
Dad's 2000 Chevy 4x4 with the 5.3 keeps popping the EVAP code, he brings it to me to get me to clear the code and he goes on his way, happy the lights out for another week or so.
Hi there, same here I been working in our cars since early 80s. This all by wire vehicle's are something else. I do all mechanic and electronics in any car, have all this fancy gadgets as well. Just gotta keep up and going. Kind regards from Bogota Colombia South America.
I've been chasing misfires and purge valve codes for a while now. I have thrown a few parts at it...tune up, distributor, fuel pump (it was getting noisy anyway). I never thought of the ECM! That might be the ticket. It's a 2005 GMC Safari van. The codes are the dreaded P0300 and the Evap vaccum leak. The purge valve works as I hear it clicking, but I may still have a leak.
I have a truck just like that plagued with evap issues, will definitely share this vid with my mechanic... Lol j/k that's me! Last resort paying for ecm. Thanks for the info on the bulletin about the hoses, I was afraid to pull it off and breaking/cracking them. Love your vids btw! Side note I have 160k miles on my 4wd Z71 ext cab so far
For stuff controlled by a MOSFET ("high power transistor"), stick in a 1 Megaohm resistor parallel to your DMM wires. Some MOSFETs (and Diodes for that matter) tend to leak a very small amount of current that can build of a charge on the switched side. From the point of any equipment that uses power, the circuit is OFF, but when no load is connected a DMM can read "ON". For this reason, i'm usually including a 1 meg resistor across all MOSFETs on my circuit boards (at least those that might not have a load connected at all times). It's not a problem in the case of this video, just trying to help avoiding possibly time consuming wrong diagnosis.
As someone who has dealt with delivering and stocking auto parts for the last 2+ years, the listing of specific part numbers for different brands just helps the source person(s) be less confused. Having line codes shown would be beneficial but that would be a per-retailer basis and not a producer basis, as everyone's line code system is different.
As an owner of a 142k mile CLK230 W208, I had a confusing problem. The problem was that it dropped a random cylinder, but run beautiful with no overheating issues, no loss of compression and no leaks. In other words it shut fuel and spark off to any 1 of the 4 cylinders. It would run like a cylinder gasket leak. This is a protection if a misfire was detected. Originally I thought it to be a duff plug, so installed with new plugs and coil packs. This, however did not fix the issue. I scanned for DTCs to find a multitude of parameters well outside the factory parameters and codes. Now, one has to point one small, but important detail out. I filled my fuel tank with E10 fuel. From this point on the misfire began. But I did not believe it to be the fuel. I could of gone through all the other fixes, but would of got expensive. Realising that E10 may not well on the older cars, I had to drain and refill with E5 99 Ron fuel. It the car runs sweet again and parameters are now within its factory parameters. The moral to this story, don't use the nasty E10 fuel on older vehicles with a bit of milage on it.
All the complexities of cars today and the equipment to troubleshoot and maintain them along with the training required is no wonder it costs tons of money for relatively simple repairs. The days of the shade tree mechanic are fading fast. Back when I was a kid in the last century, a car with 50k miles on it was considereed old. Now it's not unusual to get 150k+ miles and still be a young car.
As usual great diagnostic Raymond and I like the way you did a double check to make sure that the ECM was not functioning properly and I just thrown apart in it the valve that was sent that was stuck open and burned up hey as usual great job really appreciate it you inspired me I'm going to get some work done on my back next week and I just want you to know you inspired me I put an alternator in my car today in an hour in a parking lot but hey man you got an old man going thank you very much hey have a great evening I appreciate everything you do
The new ECU will be programmed from factory with the correct firmware, so that's why it's able to communicate and function out of the box. I think what needs copying over are the specific calibration values for that particular car.
I'm loving the GM content. I manage a small fleet of duramaxes and vortecs and I am the only light duty truck wrencher we have at our small construction company. Rare faults for others seems like a daily headache for me 🤣😂😅
Ray, heater hose isn’t sufficient for that repair. It’s not fuel or fuel-fume resistant. There’s actually a form of fuel line made by Gates Rubber Co. that is. You could probably get away with using some silicone hose for that. I worked in the parts store industry for 30yr. I know what I know “REEE”!
Heater hose will NOT hold up! Nowhere near as long as fuel line. I’ve seen it MANY times over my 30yrs in the auto parts parts business. I don’t care what ANY TSB says, don’t use heater hose where any petroleum (liquid or fumes) go through it! I’ll argue with whoever came up with that TSB until they realize the fault that they are causing!
That programming thing, Ugg. To bad your shop doesn't have a cardaq and laptop to do their own programming. Guess that takes skilled technicians to perform though.

As an old shade tree mechanic, one of the things watching this channel has amazed me is that although I know that codes are stored to tell you what's happened, I didn't know that with the right scan tool you could activate/deactivate subsystems all over the car.
Having to call and make an appointment to install a new computer is startling.
There is still a lot of basic wrench turning that goes on, but wow, I'm never attempting to work on a modern car except to change the oil or maybe do brakes.
You and Eric should meet up for a beer, might be a long drive, for you both.. enjoy both of your channels very much.
You are the very best at explaining and diagnosing vehicle problems
As I get older I miss the days when you didn't need a computer in your car/truck.
I can buy a small battery operated computer that can talk using satellites in orbit for a few hundred. But one to talk to my truck is a couple thousand and the wiring diagram is extra. What a rip off.
You mean with a carb?
And gasoline, no ethanol, where the truck could sit for 20+ years and you just toss in a new battery and it fires right up.
@@michaelvangundy226 It's because most car manufacturers are using 20+ year outdated technology for their car computers, even today. This is also why the chip shortage is such a big deal. Because the semiconductor companies can't deal with manufacturing 20+ year old parts (which require a different process) when they are so behind on MODERN parts. Plus keeping production lines for such old hardware is expensive. (Consequently this is also why Tesla is not affected by the chip shortage nearly as much, because they use modern stuff.)
@@StormsparkPegasus What you say is indeed true, however Tesla is going to find that theit new design Chips are going obsolete faster than ever. One example I can see rearing its ugly head in the not too distant future is the displays used on Tesla's will almost certainly go obsolete in the next 3 to 6 Years, especially if your Tesla is already 3 years old.
Boycott electric cars
Thank you for testing the ground wire for a short to ground! I was hoping for this test before you condemned the ECU.
Looking at what has to be done for diagnosis now a days, I'm glad I got off the bench years ago.
Give me points & condensers anyday. Great work Ray!
The volume of your uploads is amazing, especially considering your video quality.
As an Avid Eric O fan, I appreciate the name drop, both your channels are a great learning tool, thanks!
I watch only two auto repair channels - yours and Eric O's. I know how to spin wrenches, but you guys are master classes in diagnostics.
Been a tech since 1981 nice videos to see what is going on now. Thanks
This is another great diagnosis and repair. Everyone have a great day.
I like how you troubleshoot different things to make sure you get a true repair. Great show
Paint works well 😌 lol.
That's exactly how I would fix e vap system done it many times.
The programming ppl seem to be God on this video 📹.
Lack of rot is making me want to move lol . 😆
Be safe and have a great day.
Only Fords require 2 keys from what I've seen. :)
Nice work as usual Ray. I'll bet the solenoid shorted and took out the driver, but I suppose the order of failure isn't really of important. What matters is it's fixed.
My 1996 Chevy and 1976 MG both require 2 keys.
They are talking about 2 ignition keys.
So glad I live in southern Arizona. It would take 100 years for a vehicle in Arizona to turn into a rustbucket like 10 year old vehicles in Florida. Of course, the plastic parts on vehicles here are pretty well shot in 20 years from the intense UV light.
Florida vehicles dont rust lol
@@fastsvtt They do if they're near the coast where the salty air from the ocean gets to them
Or 5 years here in New York :(
Programming/reprogramming ECMs is such an interesting process. It's like you've used 2 very different skill sets. [and it 'solved'/resolved the misfire issues]
Ignition is handled a similar fashion. The ECM maintains ground on the coil (iirc) and disconnects the ground to cause a spark to fire across the plug. The fried ground circuit was probably preventing the ECM from being able to disconnect the ignition grounds properly, or could have been preventing the ECM from grounding the injectors to fire. (The ECM uses ground instead of the +12v line to control a lot of stuff.) Either way, the result was the same. And the failed evap valve was the clue to find the culprit of it all. Ray actually made it a point to make sure the ECM was bad, which is great.
Impressed me with that diagnosis/repair.
in my industry they were plagued with damaged pins when seating connectors. As such, they REQUIRED an inhouse certification called mate/demate. It was a frequent retraining lasting 4 hours. One simple and essential element was: visually inspect both connector halves before mating. I still do this for any of my electronics.... Cars too!!
Awe! You help couples who have a hard time trying to make babies! What a noble profession! And that you can translate that to automotive issues...wow!
I really like your channel, you are a gentleman and a scholar. I hope some day I could shake your hand, Your a very knowledgeable person.
My first reaction to that RAP (remote assisted programming) tool experience was when do you ask for a refund and send it back! I presume it's the lesser of evils working in a shop that takes all makes as yours does tho, as otherwise you'd have to have dozens of different programming tools. I prefer complete control of the job end to end, so I'm glad I only focus on GM brand module programming to do it myself seeing that _remote_ experience you had there. ;-)
BTW, those ACDelco and GM part numbers are not always the same. They are the same for parts only GM sells from the dealer, but anything ACDelco also sells retail will have their own unique ACD number in that field.
Everything you did today is beyond my reach I was taught back in the 70s about automobiles and now that automobiles have all these computers and all these sensors to be quite honest Ray this crap scares the 💩out of me. Ray can you recommend a school or somewhere I can teach myself that information? God bless your boss you’re the man✝️✝️✝️
Dad's 2000 Chevy 4x4 with the 5.3 keeps popping the EVAP code, he brings it to me to get me to clear the code and he goes on his way, happy the lights out for another week or so.
Hi there, same here I been working in our cars since early 80s. This all by wire vehicle's are something else. I do all mechanic and electronics in any car, have all this fancy gadgets as well. Just gotta keep up and going. Kind regards from Bogota Colombia South America.
I like it that you're so honest !!!
Glad to see I’m not the only one that doesn’t like straight cuts!
Wow.... extensive process. Things have changed since the 80s
You and Eric O are the bomb! So fun to watch y'alls vids.
When you check purge you also need to command it to seal and make sure it's not pulling vacuum when commanded off ...
I've been chasing misfires and purge valve codes for a while now. I have thrown a few parts at it...tune up, distributor, fuel pump (it was getting noisy anyway). I never thought of the ECM! That might be the ticket. It's a 2005 GMC Safari van. The codes are the dreaded P0300 and the Evap vaccum leak. The purge valve works as I hear it clicking, but I may still have a leak.
21:02 who noticed the Chevy had a German plate in the front
Oh and I think electric avenue is a good background song
Parking ze auto and poppening ze hood applies for this car👌
I have a truck just like that plagued with evap issues, will definitely share this vid with my mechanic... Lol j/k that's me! Last resort paying for ecm. Thanks for the info on the bulletin about the hoses, I was afraid to pull it off and breaking/cracking them. Love your vids btw! Side note I have 160k miles on my 4wd Z71 ext cab so far
I love your videos. Watching a true professional do his job and do it well is very nice. Thanks for that.
This is a really good one. You're a smart mechanic. Wish your shop were here in Pa.
No rrrreeeesss here. What a pain all this emissions crap is. Glad to see your excellent work.
I was getting worried there wasn't going to be an upload, thanks for the entertainment Ray!
Nice work! Just a suggestion, you can take a butane torch and warm up the hose, and it slips right off the old vent valve !
For stuff controlled by a MOSFET ("high power transistor"), stick in a 1 Megaohm resistor parallel to your DMM wires. Some MOSFETs (and Diodes for that matter) tend to leak a very small amount of current that can build of a charge on the switched side. From the point of any equipment that uses power, the circuit is OFF, but when no load is connected a DMM can read "ON".
For this reason, i'm usually including a 1 meg resistor across all MOSFETs on my circuit boards (at least those that might not have a load connected at all times).
It's not a problem in the case of this video, just trying to help avoiding possibly time consuming wrong diagnosis.
As someone who has dealt with delivering and stocking auto parts for the last 2+ years, the listing of specific part numbers for different brands just helps the source person(s) be less confused. Having line codes shown would be beneficial but that would be a per-retailer basis and not a producer basis, as everyone's line code system is different.
I need to get one of those scanners.. I'm still using my ear with an old broom stick to find clicks, dings and misfires..
And it works, doesn't it?
@@mikeboring2172 yes it does.. haha..
As an owner of a 142k mile CLK230 W208, I had a confusing problem. The problem was that it dropped a random cylinder, but run beautiful with no overheating issues, no loss of compression and no leaks. In other words it shut fuel and spark off to any 1 of the 4 cylinders. It would run like a cylinder gasket leak. This is a protection if a misfire was detected.
Originally I thought it to be a duff plug, so installed with new plugs and coil packs. This, however did not fix the issue.
I scanned for DTCs to find a multitude of parameters well outside the factory parameters and codes.
Now, one has to point one small, but important detail out. I filled my fuel tank with E10 fuel. From this point on the misfire began. But I did not believe it to be the fuel.
I could of gone through all the other fixes, but would of got expensive. Realising that E10 may not well on the older cars, I had to drain and refill with E5 99 Ron fuel. It the car runs sweet again and parameters are now within its factory parameters.
The moral to this story, don't use the nasty E10 fuel on older vehicles with a bit of milage on it.
I use a load to test triac inputs , meters always show volts on triacs , test filament lamps work well to see if triac on or off.
Nit very honest people in this business. Most would just load the parts cannon and have at er. Great video
All the complexities of cars today and the equipment to troubleshoot and maintain them along with the training required is no wonder it costs tons of money for relatively simple repairs. The days of the shade tree mechanic are fading fast. Back when I was a kid in the last century, a car with 50k miles on it was considereed old. Now it's not unusual to get 150k+ miles and still be a young car.
I'm guessing the vehicle owners enjoy seeing the effort taken to diagnose and repair their car or truck...I know I would!
Very interesting, I'm learning things....didn't know how that all worked but it does make sense.
As usual great diagnostic Raymond and I like the way you did a double check to make sure that the ECM was not functioning properly and I just thrown apart in it the valve that was sent that was stuck open and burned up hey as usual great job really appreciate it you inspired me I'm going to get some work done on my back next week and I just want you to know you inspired me I put an alternator in my car today in an hour in a parking lot but hey man you got an old man going thank you very much hey have a great evening I appreciate everything you do
The new ECU will be programmed from factory with the correct firmware, so that's why it's able to communicate and function out of the box.
I think what needs copying over are the specific calibration values for that particular car.
That is quite the procedure what a pain
Nice of you to mention Eric from South main auto, he is a great mechanic
Ray . Your nice heat gun works magic on them plastic lines . Heat some then push line on barb while heating , bottom out let cool.
I'm loving the GM content. I manage a small fleet of duramaxes and vortecs and I am the only light duty truck wrencher we have at our small construction company. Rare faults for others seems like a daily headache for me 🤣😂😅
i love to watch your work on car, and your voice. it make me happy and sleepy. especially i watch your video at night before sleeping. thumb up
I can see why there isn't that many independent repair shops anymore The Way automobiles are becoming excellent job well done
I realy like the way that you work, and trouble shoot everything. Your vids are enjoyable
You definitely confirmed this problem 3 ways at least.
Ray, heater hose isn’t sufficient for that repair. It’s not fuel or fuel-fume resistant. There’s actually a form of fuel line made by Gates Rubber Co. that is. You could probably get away with using some silicone hose for that.
I worked in the parts store industry for 30yr. I know what I know “REEE”!
Your not supposed to use garden hose as a heater hose but I've seen it done and lasted for years without failure....
The TSB states to install 5/8 heater hose and route it to an area above the transmission (not re-connect it like Ray did)
Heater hose will NOT hold up! Nowhere near as long as fuel line. I’ve seen it MANY times over my 30yrs in the auto parts parts business. I don’t care what ANY TSB says, don’t use heater hose where any petroleum (liquid or fumes) go through it! I’ll argue with whoever came up with that TSB until they realize the fault that they are causing!
That programming thing, Ugg. To bad your shop doesn't have a cardaq and laptop to do their own programming. Guess that takes skilled technicians to perform though.
Eric O and Ray.....the best.
I learned on a flathead 1950 Ford. All I had to know was "righty tighty lefty loosey". Times change.
Damn, a 2004 with 51k miles. That's crazy!
I have a 04 2500hd with 51,800 10yold tires too .
