This is for an lg4 '84 Grand Prix. I know this is a stupid question, but how do you loosen the pump/bracket so the belt can be removed. The pump has 2 belts attached, one attached straight to the crank pully, and the second attached to the crank and air compressor. Any advice would be greatly appreciated. Thanks

 

There is one pivot bolt, and three bolts that allow adjustment (in slotted openings). One of these three is actually on the back side of the pump (could be a bolt OR a nut depending on application) in a fairly well hidden area, ,down low (sorry, no photos). This hidden bolt or nut can be a PITA to access, too.
