To replace the water pump, you remove the top shroud of the radiator fan/ radiator cover, then remove the serpentine belt. Now the fan nuts, remove the fan and bell cover. Then the 4 bolts that hold on the water pump. There are 2 on each side, 1 high and 1 low. There may be a need to move/remove accessories like the alt. Or a.C. But not on the 4.3 liter. When putting it back, some silicone sealant on the gasket will help them stay put. Also a bolt on the top of each side will help keep the gaskets aligned. When the bolts are started, add the bottom bolts on each side to ensure alignment of the gaskets. Only when you know for sure that all is okay with the gasket alignment and that the bolts are in the right place do you proceed to tighten them. Do so to specs and do it evenly.
