A/c Compressor

[PHAREAL]

I Have An Olds Aurora With 162,ooo Miles On It. The Ac Compressor Pulley Seized And Snapped My Serpintine Belt.
I Want To Go Get A New One From The Junk Yard But I Need To Know How Many Different Types There Are. Can Anybody Tell Me If There Are Different Types Of A/c Compressors Or Do All 95's Through 99's Use The Same One

I would not get a used one from any recycle yard. I'm refering to the compressor. Kick down a little more money for a rebult compressor & clutch, also the receiver dryer (accumulator) & orafice tube. They will put some oil in the compressor, they will know how much, (if needed). also they will evacuate & recharge the system, & Flush the system. An AC shop will do this all for you with a warranty. I say all this because there is no warranty on used parts or labor. You will have to pay $$$ should the used part not last. I mean pay to R & R and get another one. If a shop does this work & "they" get you the (new or rebuilt) parts, then "if" something shuts down your covered. After all is said & done this should last bout 4 0r 5 years! You might need an O'ring or pressure switch sometime during this but its small items.Warranty on hard parts is usually a year. be cool!

I agree. I'm all about saving money with used parts if i can, but this is one thing that is not worth it. New parts are the only way to go.

I was going to do the job on one of my 95's, but after reading all the details (oil amounts, parts, labor, evacuating and recharging) that go into making the system work correctly, I put a shorter belt (6k739 Gates#) on to bypass the compressor. I live in Michigan, so air does not mean that much to me right now.

Pull the orifice tube to see if the pump went out and filled the system with debris. That's what mine did. When I saw that I decided that the best way to go is to replace everthing that I can get to (including condensor). What's another $140 when your going to spend $600 to get it working. It is insurance to me that it a peice of the old pump won't destroy the new one.

Will,
How did you bypass the a/c compressor? I haven't looked yet, but is it easy? I wonder if it involves a lot of rerouting. I can't get a visual in my brain of it right now but hopefully it should be easy.

[Sweet William]

No rerouting. Just the use the shorter belt and skip the ac pulley.

Badass! Hopefully I can pick up that belt this week. It just needs to warm up here, as it was only 7 outside at 10am.

Talladam,

When it's time to change the AC compressor (if you opt to do it yourself), I wouldn't bother to pull one off at the local wrecking yard either. AC compressors are a common item to fail on Auroras and there's no guarantee that the one you're getting will work at all or for very long.

Considering the amount of work involved to change an AC compressor, you definitely shouldn't waste your time installing a used one. This is certainly not a job that you want to do more than once. I think a rebuilt unit from AC Delco from gmpartsdirect.com is in the $320 range.
