Expert:  Gary replied 1 year ago.

the odds are the small AC belt has broken as seen here

there are 2 belts on this engine

either the belt just broke because it was old OR the small belt tensioner went bad OR the AC compressor is failing and broke the belt

its best to make sure the tensioner is good and the pulley on the compressor spins good by hand if so try a new belt if it breaks again the odds are the compressor is failing and locking up breaking the belt

how are you making out ?
