Need to replace my Compressor on my 2002 Chevy Suburban.

Greetings,
I am new to the forum.

I own a 2002 Chevy Suburban 1500 with rear AC (flex fuel) and my compressor has gone bad. Makes a loud noise when engaged and has caused the tensioner and belt to break.

It's toast.

In the interest of saving money I have looked into trying to do this myself, but I am very nervous, because I recognize that there is only so much information you can get from a video.

I have been following this video and installation seems that it can be done without TOO much difficulty, but upon more research, it doesn't mention anything about what to do differently for a rear AC unit and/or the AC Condenser since according to Scotty Kilmer I would more than likely want to replace the condenser also, which this video makes NO mention of.

Any tips? I know it is a loaded question.

I should note that I have already bought the compressor:

All AC Delco.

The ac compressor does require oil and refrigerant. the low pressure switch protects from low pressures that will cause the compressor to seize if this switch allows the compressor to run on low levels of both it will break belt and cause a failure .

It appears you have no idea what to do or even the proper tools. I do not recommend that you do this repair.

I do have a hvac license to work on ac systems and it is not a simple task. buying an ac compressor is the easy part .. installing and then it will continue to work that would be a miracle with your education level on this. You tube video is helpful , so on specific ac systems you will get special tips etc.. but not a training class .

have a ac shop do the repairs which with a seized ac compressor requires a complete flushing/filter dryer/ a orifice screen. vacuum pump leak check. adding the correct oil and refrigerant. pressure testing for the correct system operation .

Thanks for the info.

Well, it turns out I don't need to replace the compressor right now. I got my AC working for the moment.

According a friend who has been a mechanic for over 30 years, it turns out that the GM cars with tensioner AC belts are notorious for breaking at the tensioner. Indeed the suburban has gone through at least 3 tensioners.

He told me that whenever he works on the AC for those types of cars he completely removes the tensioner and installs a tighter belt.

For my 2002 Chevy Suburban I was able to remove the broken tensioner and put on a belt from 2010 Yukon Denali. It was a pain to get it on, but I followed this video.

As a result the AC is working just fine. I don't hear any sounds that was associated with the AC from back when the AC was working while using the tensioner route.

I have no idea how long it will work, but the $16 cost of the belt is certainly MUCH cheaper than me spending the $$$ and effort to repair the AC myself and/or have a mechanic do it.

I have to admit that I am surprised you don't see much about removing the tensioner completely online.
