How to change power steering pump on 93 aerostar van?

Answer 1

Power Steering pump removal and installation

1. Disconnect the negative battery cable from the battery.

2. Put a drain pan under the power steering pump. Remove the drive belt.

3. Use a special power steering pump pulley remover or a 2- jaw puller and remove the pulley from the pump.

4. Remove the pressure and return hoses from the back of the pump and let the hoses drain out. Plug the hoses so no contaminants get into them.

5. Remove the pump mounting bolts and lift the pump from the vehicle watching out so as not to spill fluid on to painted surfaces.

Installation:

6. Place the pump in the mounting bracket and install the bolts. Tighten securely.

7. Connect the hoses to the pump and tighten the fittings securely.

8. Press the pulley onto the pump shaft using a special pulley installer tool. An alternative tool can be fashioned from a long bolt, nut, washer, and a socket of the same diameter as the pulley hub. Push the pulley onto the shaft until the front of the hub is flush with the end of the shaft, but no further.

9. Install the drive belt.

10. Fill the power steering reservoir with the recommended fluid and bleed the system as explained next.

Bleeding the power steering system:

1. Following any operation in which the power steering fluid lines have been disconnected, the power steering system must be bled to remove all air and obtain proper steering performance.

2. With the front wheels in the straight ahead position, check the power steering fluid level and, if low, add fluid until it reaches the Cold mark on the dipstick.

3. Start the engine and allow it to run at fast idle. Recheck the fluid level and add more if necessary to reach the Cold mark on the dipstick.

4. Bleed the system by turning the wheels from side- to- side, without hitting the stops. This will work the air out of the system. Keep the reservoir full of fluid as this is done.

5. When the air is out of the system, return the wheels to the straight ahead position and leave the vehicle running for several more minutes before shutting it off.

6. Road test checking for any abnormal noise or any problems.

7. Recheck fluid level to be sure it is up to the Hot level on the dipstick while the engine is at normal operating temperature.
