Squealing fan belt

Oddly enough I dreamed about a squealing fan belt last night. That belt was the wrong section \_/ . I could see where the belt was riding the bottom of the grooves. It's not supposed to. Anyway... 72 has a single a/c drivebelt and some idler pulleys ?
73 has 2 belts on the a/c and those would squeal too unless you paid more for a matched set. Good luck with it.
