Disconnect the battery, remove the serp belt and steering hoses. Next unbolt the pump from its mounting brackets.
Reverse the procedure to replace.
Next, you need to bleed the system,
Bleeding will take significantly longer on a system that has been completely emptied and/or on systems that contain long fluid lines and multiple components (such as a fluid cooler in addition to the pump, gear and reservoir).
1. Begin the bleeding procedure with the engine and fluid COLD.
2. FIRMLY set the parking brake and block the rear wheels.
3. Raise and properly support the vehicle.
4. Turn the steering wheel to the full left position, then check and top off the fluid reservoir to the FULL COLD mark.
5. Turn the steering wheel from lock-to-lock at least 20 times, while an assistant checks the fluid level and condition in the reservoir. Add fluid as necessary to keep the level at or near the FULL COLD mark.
NOTE
Remember that if only the front wheels are raised, the fluid level on the dipstick will not be completely accurate. Keep the level a little below the mark, until the vehicle is lowered, then check and top it off as necessary.
6. Carefully lower the vehicle. If not done earlier, install the filler cap to the reservoir.
7. Start the engine and allow it to idle. Run the engine for approximately 2 minutes in order to allow the fluid to warm-up.
8. With the engine idling, turn the wheels in both directions (to the stops) several times.
9. Stop the engine, then check the fluid level and condition. Add power steering fluid to the level indicated on the reservoir.
NOTE
Fluid with air in it will have a light tan or milky appearance. This air must be eliminated from the fluid before normal steering action can be obtained.
10. Road test the vehicle to make sure the steering functions normally and is free from noise.
11. Allow the vehicle to stand for 2-3 hours, then recheck the power steering fluid.
