This is a 2000 Olds Silhouette with about 155K on it. The A/C works.
I do have a squeaky cricket sound coming from my A/C pulley - 99.9% certain that’s the one. (Why couldn’t it have just been an idler pulley or something?)
The questions are:
what are the odds that it is just the pulley bearing rather than the bearings in the compressor? The reason I think its just the pulley is that the sound is there with the A/C engaged or not, and the sound doesn’t change if you engage/disengage the A/C. It shows no sign of a problem just spinning it with the belt removed & the car off, but if I wrap the belt around it to apply some pressure as I rotate, it squeaks. I’m guessing that means just the pulley, but I’m not sure.
Second, since this is a GM, removing the clutch/pulley assy from the compressor requires the special puller tools. Access to the tools isn’t the problem as I often use the “loaner tool” programs from major auto parts chains. The question is what my odds of success will be if I want to do this without pulling the compressor. The compressor is mounted very low down at the bottom of the engine. As far as I can tell my only access is from the top. I have all of about 6 inches of clearance between the frame & the front of the compressor. Can it be done? Are the odds of success good? Some rust is present, but its not bad - the car spent its whole life in the Mid-Atlantic, so it sees some corrosive conditions, but not bad all in all. I’ve never done it even on the bench, let alone while still mounted and not easily accessible.
If I can’t get at this myself, I suspect most any shop will want to either replace the compressor entirely (not an odd thought, admittedly) or at least do a complete R&R of compressor to do the pulley. I’ll dump the van before I spend that kind of $$ on a squeaky pulley.
