OK, here's the deal......I shredded the belt that turns the A/C compressor. I bought a replacement that is the same size as the broken one but can not get it on. I do not have the belt routing diagram on my truck and the Haynes manual instructions go into no more detail than, "replace the belts." The belt appears to wrap around the crank pully, water pump pulley, power steering pulley and the ac compressor pulley but when I loosen the ac compresor and pull it all of the way in, I can still barely get the belt on. If it is the same size as the one that was on there, I have to be routing it incorrectly. Does anyone know how I could view a routing diagram (maybe online) or could someone explain how it routes? Here are the particulars: 1987 GMC Jimmy 5.7L w/TBI Thanks a bunch!!!
