Replacing Serpentine Belt
#17
#19
I'm hearing a high pitched whir around my AC compressor when I hit 2500 RPM and have to shift up to avoid the sound. Seems to be the pulley that connects to the belt, which means I would have to replace the entire compressor which pumps AC just fine. How do I know if I need to replace the compressor or just the belt?

Unfortunately no, that's not good news. After being used so much the ac compressor clutch plate stays engaged, which keeps it on constantly. The plate gets magnetized to engage the ac and after a while it just stays magnetized, you probably have some metal shavings in between the base of the pulley and the compressor, or worst case scenario the refrigerant seeped out of the system and the compressor is constantly running unoiled which will cause it to seize up and shred your serpentine belt. I'd recommend taking it to a shop that specializes in auto ac work and tell them the problem. I had the same problem on an old chevy cavalier of mine, cost me $90 to have it fixed.
