I just installed a brand new ACDelco (Delphi) A/C Compressor 3 months ago. Well, lo and behold, it has begun to make a rattle/squeak/noise from the clutch portion of it while it is engaged. While it is not engaged, it makes a ticking noise. Looking down on it, it looks like it may be loose or something. Has anyone else ever heard of a problem like this? It sounds like belt squeak and its driving me nuts! Can I oil it?

EDIT: By the way, this is NOT from the Compressor itself, I am almost positive anyway. The car cools great and the pressure reads fine.

 

have you took the belt off and spun it by hand, also get some feeler gauges and check the air gap between the pulley and clutch. only thing i could imagine is some debri between the clutch and pulley, or the clutch is possibly bent
