TTA A/C Compressor part number??

[Jan Larsson]

Anyone recently replaced their A/C compressor and have the GM/Delco part number to order?

I had my system done yesterday ... vacuumed, pressure tested and refilled with r134a ... and worked fine and held pressure etc however today I got an oil leak at the compressor looks like, still have to get under the car to make sure it's the compressor but small puddle under the car after been driving it for an hour or so today and also oil underneath the compressor housing :-(

I replaced pretty much everything except for the original compressor and hoses and hoped it would work but apparently not so thought I'll start looking to get hold of a brand new compressor as a starter ..

Any help much appreciated.

I used a compressor made for a 5.7L Trans Am I believe. The pulley looked a bit different but it bolted right in.

The Buick compressor is the same.

The pulley is different, so the bonus is you'll get additional clearance on the idler.

Thanks guys, looks like the ACDelco 15-20225 is what is used on the GN (and only listed to fit the GN) and the ACDelco 15-20227 is the one listed for the TTA (and other V8's as well as a couple of other GM brand vehicles).

Anyone aware of any differences between the above two? Do both of them plug in and install (hardware etc) as the stock units?

I have a Four Seasons compressor #57238, which is a replacement for the V8 AC Delco unit 15-20227. Here is a link:

New Compressor 85 - 93 Cadillac Chevy GMC Isuzu Pontiac - Dallas Car Parts & Accessories For Sale - Kijiji Dallas, Texas

It was a direct bolt in for me.

I just purchased a new Delphi compressor its number CS-00010. Bought it through Napa-they had the best price. Used a Delphi on the GN and it worked well with no problems going on the third year.

Thank's guys, these all cross references to the Delco 15-20227 .... getting a few quotes in on price. My AC guy will to a leak check to make sure it's really the compressor (I'm sure it is as I got oil leaking from it) and we will then take it from there. At least I'm 100% sure what to order when we get to that stage
