How to Remove a 1996 Chevy Truck Power Steering Pumpby Dan Ferrell
When the reservoir on the power-steering pump cracks, the pump shaft seal begins to leak, the fitting O-rings on the stud or bolt leak or an internal component fails, you need to remove and replace the pump. If possible, take the old pump with you to the auto-parts store and make sure you have the correct replacement for your particular vehicle. The hose fittings should be in the same position and of the correct size for your particular Chevy truck model.
Open the hood and disconnect the ground battery cable using a wrench. This is the black cable connected to the battery post with the negative or minus (-) sign next to it.
Rotate counterclockwise the belt tensioner arm using a 3/8-inch drive ratchet and slip the belt off the power-steering pump pulley.
Slip a drain pan under the truck beneath the power-steering pump to catch the steering fluid that will drain when you disconnect the pump hoses.
Loosen the clamp holding the inlet hose to the power-steering pump fitting with a Phillips screwdriver or a pair of rib-joint pliers, depending on your particular model.
Twist carefully and pull the inlet hose off the fitting by hand. Let the steering fluid drain into the drain pan.
Position a back-up wrench on the nut molded into the case of the pump, where the pressure hose connects, and unscrew the pressure hose from the pump with a flare wrench. Let the fluid drain into the pan.
Detach the power-steering pump pulley from the pump with puller J 25034-C.
Unscrew and remove the steering-pump front and rear mounting bolts using a wrench and a ratchet and socket.
Unplug the steering pump electrical connector from the Electronic Variable Orifice (EVO) actuator by hand.
Remove the power-steering pump from the truck.
