go get a new belt, loosen the bolts on the alternater(one on the bottom above the oil pan, and another going thru a bracket on the top) when you can move the alternator back ad forth, push it up, put the new belt around the crank, water pump, and alternator, take a pry bar or somethin and put it between the alternator and ps pump, while you pry the alternator to make the belts tight, tighten the bolt on the bracket real good. then tighten the one on the bottom.
