a/c compressor R & R question

Relieve pressure, take off belt, unbolt compressor, undo fittings (have fun with that), pull out old, put in new, repeat steps in reverse order, being sure to use thread tape or sealer on fittings for a good seal.

 

You may also have to have a shop retro-fit it before it can be recharged, unless you can find a shop that wont charge you your first born child to use r12.

You should be ok by just taking off the fittings, If you dont want to do that, you should be able to find the recharge valve and expell refrigerant that way before you remove the compressor.

Not only illegal, its irresponsible and stupid to do. The way that that chemical reacts with o3 is amazing, almost resembling nuclear in the way that it seems to exponentially react.

Just a few points...

 

1. Don't pull the compressor and leave it off very long. Moisture will get in the system and degrade the receiver/drier.

 

2. When you get the new compressor on there, you'll have to pull a vacuum on it for about 30-minutes. This will remove any moisture in the system.

so very true but you could cap the ends of the line to help prevent moisture from getting in. and i would goto a shop to have them recharge it so they can pull the vacuum and test for leaks anywhere.

O.k I just found out that I need to replace my a/c compressor & would like to attempt this myself. Does anyone know what's all involved in doing this. the car is a 92 olds supreme 3.1 L.

 

Before you start to tear into your AC system, why do you have to replace your compressor?

 

If it blew it's guts, you're in for an expensive repair. "Black Death" is not a pretty sight or is it a simple repair. Very time consuming and expensive (just in parts alone). I know. I've gone thru this a few years ago (sad and long story about dealing with a shop that had no clue). The one positive is that I now have a bunch of equipment should I ever need to service an AC system again. I was also able to continue to use R12 (don't ask....don't tell). :shock:
