Engine belts 90SP36

[williamcharrison]

Can someone give me the specs or part numbers for all the engine
belts. Last trip the engine started to overheat about 20 miles from
home and i found that both fan belts and both alternator/air pump
belts were extremely loose. One oddity is that in both cases
one belt was much looser than the other. I have tightened them all
but am out of room to tighten the alt. belts any more.
