Last month the engine tossed the belt - again. So after I returned from vacation I examined it closer. A straight edge across the power steering pulley showed it to be 1/2° off, and a chip in the composite pulley.
So I bought a pulley installer/puller and a new GM pulley, shimmed one of the legs 0.054" and will see what happens this time. I wanted to use the 3/4 ton mount but they are out of stock everywhere.
