what all is involved in chaninging the power steering pumn

Remove: upper fan shroud, serp. belt, power steering pulley, filler neck (nut and clamp holds neck to power steering pump). You may not have the extended filler neck im not sure. Remove the hoses from the pump, bolts from the rear of the pump, bolts from the front of the pump, and then the pump should come out. Dont forget to put a drain pan under vehicle to catch fluid. You will need a power steering pulley puller to remove pulley. It can be purchased at almost and auto parts store. You cant remove the front bolts on pump without it.
