Once the power steering pulley is off the remaining bolts that hold the pump in place are all easy to see and a 10 minute job to remove, I think u are over complicating a very straight forward job.

    If u wish to have a factory manual that shows all this and would be invaluable for future at home repairs go to the link below for a low cost used factory service manual. the manual is for the 1996 model year but is exactly the same as the 1995 model, so all procedures would be the same, very cheap, less than $27.00 on ebay.

    buying a factory service manual is the single biggest positive suggestion i can offer, sorry u don't agree with that.

REMOVAL & INSTALLATION


  1. 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.
  2. Cap the pump fittings.
  3. Loosen the bracket-to-pump mounting nuts.

    I spke with a mechanic - 88198g35.gif






    Fig. 2: Installing the power steering pump pulley
    88198g36.gif



  4. Remove the pump drive belt.
  5. 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).
  6. Remove the bracket-to-pump bolts and remove the pump from the van.

    Fig. 5: Location of the power steering pump pulley--6.5L diesel
    and 7.4L gasoline engines
    88198g39.gif

    To install:
    NOTE: On 7.4L engines, install the pulley on the new pump with
    a forcing screw and washer tool (such as J 25033-B) before installing the pump.



  7. 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.
  8. Fill the reservoir and bleed the pump by turning the pulley counterclockwise
    (as viewed from the front) until bubbles stop forming.
  9. Install the drive belt.
  10. Bleed the system as outlined below.

BLEEDING
1987-95 Models

  1. Fill the reservoir to the proper level and let the fluid remain undisturbed
    for at least 2 minutes.
  2. Start the engine and run it for only about 2 seconds.
  3. Add fluid as necessary.
  4. Repeat Steps 1-3 until the level remains constant.
  5. 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.
  6. Start the engine and run it at approximately 1500 rpm.
  7. Turn the wheels (off the ground) to the right and left, lightly contacting
    the stops.
  8. Add fluid as necessary.
  9. Lower the vehicle and turn the wheels right and left on the ground.
  10. Check the level and refill as necessary.
  11. 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.
  12. Check that no hoses are contacting any parts of the van, particularly sheet
    metal.
  13. Check the oil level and refill as necessary. This step and the next are very
    important. When filling, follow Steps 1-10.
  14. 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.
    The procedures for maintaining, adjusting, and repairing the power steering
    systems and components discussed in this section are to be done only after
    determining that the steering linkages and front suspension systems are
    correctly aligned and in good condition. All worn or damaged parts should be
    replaced before attempting to service the power steering system. After
    correcting any condition that could affect the power steering, do the
    preliminary tests of the steering system components.

    Try to click on the 'x' for the diagram. Sometimes that works.
    I am unable to email information directly to you as per Fixya.com rules and guidelines.
    However, you might be able to get the same information by buying a chilton or haynes manual from your local store, or go to alldata.com or another automotive website to get the pictures and diagrams.

What your looking for is the length of the rear tail shaft housing on the transmission. You want to measure the length of the one on your vans transmission. You will need to get under your van and measure from where the drive shaft slides into the back of the transmission to one of the 4 bolts a the front of that housing.

95 chevy g20 idles too high, how do I turn idle down?


i would first check for a vacuum leak because this is considered a newer vehicle and does not have an idle screw, so I would get some "brake kleen" and mist it at each vacuum hose, if the idle changes then change that hose it means there is a leak, and that should sove your problem, if it doesnt , I would then check /replace the idle air control valve as this is the motor that controls the idle
