ACDelco GM Genuine Parts 15-20189 Air Conditioning Compressor and Clutch Assembly

fit as it should

Perfect fit and can’t go wrong with “genuine” product…unfortunately I had to learn this after trying to save money with “lesser” brand. First one (x brand) failed within first 10 days…won’t happen again as will always search and buy “genuine” no matter initial cost…

Installed this back in November of 2024, it’s now May of 2025. The compressor is already grinding loudly when engaged like it’s going to fail. The bearing is good the compressor itself is crap.

AC Delco is a quality part. Very quiet when running. Might cost a little more. But well worth it . Had to switch over the high pressure cut out switch. New compressor just had a plug installed. Just a snap ring removed and swaped switch to new compressor. Don't forget the oil. It comes dry.

All worked out perfect

Works great on my chevy c1500 1993 4.3lAlso try to replace the A/C Accumulator and condenser and u will love your vehicle again. Pleople complains that it failed or get hot well maybe they ignored that there are two other parts to replace. If the condenser that looks like the radiator is blocked by the dirtiness then is obviously that this compressor will fail soon or later again. I replaced all these 3 parts and my a/c is like a brand new vehicle.also noticed a big difference on my engine's performance. It doesn't feel forced like it did before. Spend a little more money but do the job right. If you just replace one old part is like buying a brand new radiator and filling it with your old antifreeze with dirt and any other contaminants which will fail soon or later. Same thing with the A/C system.

Would have been 5 stars but it did not have the pressure switch on the back like the original compressor. I had to transfer the switch over to the new compressor. Other than that the compressor works great.

Works great on my 93 K1500 Blazer. Temps coming out of the vents are around 42°
