I need to replace my belts on the v6 82 Cutlass, it looked pretty straight forward, but the guy at autozone said I need a serpentine belt tool? it was a pop up that came up in his system, I looked at the power steering pump and it looks like you loosen the 2 bolts and can move it with a 1/2' drive wrench? is this correct? and the alt and air pump bolt look like bolts you loosen and allows them to move, is there any trick? special tool? or is the autozone guy an idiot?if someone can confirm this before i dive in a find out after all the belts are off, thanks guys
