Great video! I’m a mechanic and get annoyed with people that act to silly, play to much music or just ramble on about things that don’t apply to the video. This man cut out all the fat and got right to the point. Perfect video in my opinion

Thanks man. Replaced the clutch plate. With labour all cost me around $17. The guy had to search for a reconditioned one in the junkyard. Now my A/C is working again. Kudos to you sir.

I’ve been researching videos today about to correct my AC on my own, and by far, this has been the best! I appreciate how you modeled via the compressor itself in terms of what was the compressor, the bearing, clutch, etc.

I have watched countless repair videos and I have got to say, this might be the only clear and concise video, on any car repair I've ever seen, thanks

[kaypay]

This guy is more real and sincere than so many mechanics out there.
Thank you Sir and thank you YouTube University.

Best educational video on maintenance of an AC compressor I've ever watched.

Thanks for the video. I just changed the bearing on my 2002 Suburban and your video was spot on. A tip if like to forward. On the Suburban the compressor is surrounded by the idler arm, frame and radiator hose which made getting it apart a challenge. When I removed the bolt in the middle of the compressor driver I used an old metal oil filter wrench to hold the compressor driver in place while I turned the bolt. Worked perfectly in the confined space. Thanks again.

Concise. To the point. Easy to understand. One of the best DIY videos I've seen so far. Thanks!

I've got a 2000 Jeep XJ and a cheap wife, so I watch A LOT of DIY repair videos on here, and I just gotta say that this is just flat-out one of the best I've ever seen. Good camera angles, good lighting, perfect explanations about how everything works individually and as a system, no useless mumbling banter or side-topics that aren't relevant . . . just pure relevance and good, clear information all the way through. I think you just got a subscriber. This is exactly how videos like this ought to be made. You rock!

i have a 1978 dodge motorhome and over the last few days I've had this squealing coming from under the hood near the alternator and air compressor, tried spraying WD40 around the belts, still get the squealing. you just made my life so much easier because of this video because i was dreading how much this was going to cost me. you just gave me a quick and simple way to see if its the bearing and if it is replace it

THANK YOU!

Great information for DIYrs. Learnt a lot of this when repairing customers A/C systems. The Brown dust around the clutch is always a good indication of a failing bearing. I have also found the spacer will need to be thinner or take out a shim or two if they are fitted, this compensates for the wear on the pulley and hub faces in use. always ensure the airgap is back within spec as to greater gap can cause non-engagement or worse overheating of the magnet coil.

Excellent video! Straightforward, well-organized and the video quality is GREAT! Much appreciated for this and for your directing us to the more detailed videos on the right.

Best auto video I have ever seen. Great job covering the potential hazards of this process. Fast and effective communication. Outstanding and well done!

Thank you for taking the time to film this. EXTREMELY helpful. Bad bearing repair coming up

[mufuliramark]

I'm not a mechanic but this tutorial has given me the confidence to do it myself. Great Video. Thanks

[JoeLinux]

Very well done clear explanation. One small point the bearing your refer to is the AC clutch bearing, not the AC compressor bearing, which would be inside the compressor. Additionally you should be able to check the clutch activation coil with an ohm meter to see if there is continuity. No continuity through the coil = a burned out coil. Since the compressor is near the 12 V battery in the car, you should be able to use a small clip wire to test the coil in the fashion you did. I hope you are correct about the polarity of the colored wires. It might be a good idea to use an ohm meter to check for continuity to ground before apply power, or you could also check for voltage in the wire with either a volt meter or pin poke tester that uses a light which is usually easier than a volt meter.

[VanRolle]

You are indeed a professional and this is the exact information i was looking for to assist me in checking my compressor

[youg]

Even though this video is from 5 years ago but It helped me so much now. Thanks for the great explanation of how the compressor works and posting this video.

Hands down the best AC compressor coil repair on YouTube - or perhaps ever seen 💯

[violetvioletviolet]

By far best DIY instructional video I have seen on car repairs! Great job man! Look forward to learning alot more from this guy! Ty
