I have an 87 Blazer that I just swapped motors in. For the life of me I can't get the belts back on. It has 3 of them. 2 V belts and one ribbed belt. I thought that one V-belt went around the crank, watter pump, PS pump and the A/C. I can not get it to go back though. I can't see how else it would fit either. There is no diagram on the core support either.
