Re: ac compressor vs ac clutch?

Old thread, but rather than removing the belt, turn off the engine after running for a few minutes and touch the pully to see if it is hot. It should get really hot if the belt is slipping with good tension on the belt. Also, check that the belt is tight and that the tensioner arm moves freely (assuming it has one) keeping in mind tnat the arm contains a tight spring.

FYI, Rod is correct that it is not legal to vent an ac system without capturing the R134a. However it is interesting that you can buy "canned compressed air" intended to be vented directly into the air that is 100% R134a.
