Alright, first disconnect the negative battery cable, we don't want uncle Bob trying to start your truck with you under the hood and you don't want to get hit by anything that has a charge runnung through it. Second, remove the serpentine belt, This is done by putting a 1/2 inch wrench of the back side of the tension pulley and removing the tension. third, you're going to have to borrow, buy, or steal a pulley puller to remove the pulley on the poower steering pump. Then there are the hydraulic lines... the low pressure side can be removed with flat head screwdriver. the the high pressure side is a pain to remove so have fun. IF you can afford it, it's good practice to replace the lines anyway. You may end up bending then anyway. Next remove the bolts that hold the pump in the bracket. There are three and they are 1/2", Reverse the process if you want to put one back in.

Need instructions for power steering pump replacement on a 1992 pontiac trans sport. FAST PLEASE!!! has a 3.8L engine with a/c. thankyou for your help!


-- from the 1990-1999 Lumina / Silhouette / TranSport Repair manual ---

1992 Pontiac TransPort Power Steering Pump REMOVAL AND INSTALLATION

  1. Disconnect the negative battery cable.
  2. Disconnect and cap the power steering pump hoses.
  3. Remove the accessory drive belt.
  4. Remove the power steering pump pulley using a suitable puller tool.
  5. Remove the pump mounting bolts and remove the pump from the vehicle.

See Figures 1, 2 and 3

Fig. Fig. 1: On some vehicles, you must use a puller to remove the power steering pump pulley

  1. Installation is the reverse of the removal procedure. Tighten the pump mounting bolts to 18 ft. lbs. (25 Nm).
  2. Bleed the power steering system to remove trapped air. Air in the system could cause noise and or damage to the pump.

BLEEDING

This procedure requires the help of an assistant.
  1. With the engine OFF, the wheels off the ground and turned all the way to the left, fill the fluid reservoir to the FULL COLD mark on the fluid level indicator.
  2. With an assistant checking the fluid level and condition, bleed the system by turning the wheels from side to side without hitting the stops. You should repeat this at least 20 times, making sure to keep the fluid level at the FULL COLD mark.

Fluid with air in it has a light tan appearance. This air must be eliminated from the fluid before normal steering action can be obtained.
See Figure 4

Fig. Fig. 4: Power steering bleeding procedure

  1. Start the engine, and while it is idling, recheck the fluid level and add as necessary to reach the FULL COLD mark.
  2. Return the wheels to the center position. Lower the front wheels to the ground and continue running the engine for 2 or 3 minutes.
  3. Road test the vehicle to make sure the steering functions properly and is free of noises.

See Figure 5

Power steering light comes on and then I loose power steering


Gonna take a gander at a guess, and say a power stearing pump. Are you losing power brakes at the same time? If so, probably a serpentine belt. Or a loose pulley (bearing) in there. If only power stearing, check the power stearing fluid first.

Power stearing pump pully alighnment


Assuming that everything else is OK, first, sight down the belt/pulley arrangement and make sure that everything is aligned correctly. If the pump pulley is not lined up and the pump is a remanufactured unit, it is possible that they pressed the pulley either too far, or not far enough onto the pump shaft. (any machine shop can correct this). If any other pulley is in or out too far, either the component is incorrect or shims are needed to get proper alignment.
