jdcutty Posted February 20, 2006 Report Share Posted February 20, 2006 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.

92SL Posted February 20, 2006 Author Report Share Posted February 20, 2006 How do I relieve the pressure & by that do you mean evacuating the old refrigerant? I've never touched a/c components before so I'm grass green when it comes to this Quote Link to comment Share on other sites More sharing options...
jdcutty Posted February 20, 2006 Report Share Posted February 20, 2006 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.

99RegalGS Posted February 21, 2006 Report Share Posted February 21, 2006 FYI It is VERY Illegal to release R134a or R-12 into the atmosphere. But if the system is already empty it's fine to disconnect. Quote Link to comment Share on other sites More sharing options...
JakeMetz63 Posted February 21, 2006 Report Share Posted February 21, 2006 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. Quote Link to comment Share on other sites More sharing options...

GnatGoSplat Posted February 21, 2006 Report Share Posted February 21, 2006 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. Quote Link to comment Share on other sites More sharing options...

paulo57509 Posted February 23, 2006 Report Share Posted February 23, 2006 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: See here for more info: http://www.autoacforum.com/ Some good article to read: http://www.autoacforum.com/messageview.cfm?catid=20&threadid=9178 http://www.autoacforum.com/messageview.cfm?catid=20&threadid=9172 http://www.autoacforum.com/messageview.cfm?catid=20&threadid=7931 http://www.autoacforum.com/messageview.cfm?catid=20&threadid=7927 Hope this helps.
