how to install power steering pump on 1995 chevy conversion van 5.7 engine
Disconnect the hoses at the pump. When the hoses are disconnected, secure the ends in a raised position to prevent leakage. Cap the ends of the hoses to prevent the entrance of dirt. Cap the pump fittings. Loosen the bracket-to-pump mounting nuts.
Remove the pump drive belt. Remove the pulley with a puller such as J 25034-B, except for the 7.4L engine (on which the power steering pump pulley can be replaced after removal). Remove the bracket-to-pump bolts and remove the pump from the van.
Install the pump, then install the pulley on the new pump with a forcing screw and washer tool, then tighten all bolts and nuts securely. Fill the reservoir and bleed the pump by turning the pulley counterclockwise (as viewed from the front) until bubbles stop forming. Install the drive belt. Bleed the system as outlined below.

Fill the reservoir to the proper level and let the fluid remain undisturbed for at least 2 minutes. Start the engine and run it for only about 2 seconds. Add fluid as necessary. Repeat Steps 1-3 until the level remains constant. Raise the front of the vehicle so that the front wheels are off the ground. Set the parking brake and block both rear wheels front and rear. Manual transmissions should be in Neutral; automatic transmissions should be in Park. Start the engine and run it at approximately 1500 rpm. Turn the wheels (off the ground) to the right and left, lightly contacting the stops. Add fluid as necessary. Lower the vehicle and turn the wheels right and left on the ground. Check the level and refill as necessary. If the fluid is extremely foamy, let the van stand for a few minutes with the engine off and repeat the procedure. Check the belt tension and check for a bent or loose pulley. The pulley should not wobble with the engine running. Check that no hoses are contacting any parts of the van, particularly sheet metal. Check the oil level and refill as necessary. This step and the next are very important. When filling, follow Steps 1-10. Check for air in the fluid. Aerated fluid appears milky. If air is present, repeat the above operation. If it is obvious that the pump will not respond to bleeding after several attempts, a pressure test may be required
remember the serpentine belt routing by drawing a picture. there is supposed to be a sticker but at 17 yrs old it may be worn off or gone. if its still there then don't worry about the drawing.
