Noise on engine-AC clutch??? Pleeeease help!
I've got a 94 Buick Lesabre 3.8 with a thumping knocking noise in the engine. If you put tension on the belt it goes away and it seems to be coming from the air conditioning area. Mechanic says it could be the water pump or the ac clutch bearing. Has anybody replaced the bearing on the ac clutch? Need some help...
