I really hope that it is a greasy or dirty belt....wouldn't that be nice. Unfortunately, the belt has less than 10K and the tensioner was replaced at the same time. Right now the pointer is still showing at the top of the scale and is really tight to the touch. I'll look a little closer to see if there is any oil or dirt on the belt.

Well, I checked and the belt is tight and clean. Whne the compressor spins up it does give a bad bearing type noise....of course that goes away when the clucth disengages so I don't think it is the ac clutch bearing. Should I convert the car to 134a since it all has to come apart and since R-12 would amount to at least $350 of the repair?
