A/C Compressor replacement instructions?
Hi, does anyone have any instructions, or pointers or tips on how to do my own A/C Compressor replacement? It's making loud noises so I'm pretty sure I have to swap it out. I heard something about having to watch out for metal shavings, inline filter, etc?

I'm about to do my AC compressor and the book tells you to remove the water pump first, then the compressor. I don't want to do that, but after examining the car, I'd either have to pull the header, water pump or engine. I'll pull the pump and replace it while its off.
There are two o-rings on the back of the pump, pn 2724577. Replace them when you pull the lines off the back of the pump.

BTW most, if not all, compressors will have zero warranty unless all of these things are done. There is simply too much chance that some residual trash will get into the new compressor otherwise.

GM #3033879 and the AC Delco # as 15-5151.
The listing is for '97 and '98.
This is item #26 on page 4I-15. I have not personally had the chance to see this for my self, but if it has a screen of any sort in it like the older design tubes, then I would definitely replace it. BTW, since this item carries an AC Delco part number as well as the GM number, then you can get it through any aftermarket parts store that sells AC Delco parts. Just use the Delco number. (It's usually cheaper this way too) HTH

Unless your condensor was damaged somehow, then there is no need to replace it.HTH
