I developed a squeek that I pretty sure is coming from the A.C. compressor area. (i used a stethescope). The pitch of the squeek remains the same whether the compressor clutch is engaged or not. If I shoot a little oil behind the pulley the squeek stops, but resumes almost immediately. Anyone else have this anomaly? Is the A.C. clutch replacable?

If the noise remains the same with the compressor engaged or not then its NOT from the compressor. The pulley does have a replaceable bearing but it only rotates if the compressor is not engaged. This bearing can be replaced without discharging the system. The compressor can be unbolted to give better access but as special tools are required it may be better to have it done at an AC shop unless you have them.

If what you say about the squeal is true then look at the tensioner bearing as well as the other idlers.

Took a chance; drove it to Maine 400 miles. Squeek remains the same, I think if it was a bearing it would have fried by now. Couple of "Mainers" said it was the "rivets" on the A.C. compressor pulley. They said the rivets loosen up a bit and rattle. If I put my good ear to the pulley it could be a high pitched rattle. Thanks for the advice, I will change the clutch.

Valair sells a new complete a/c compressors with the clutch very affordable worth a call.I put one on this summer.
