Item Description
1 Power steering fluid reservoir
2 Control valve (vacuum side)
3 Control valve (fluid container side)
4 Fluid container
  1. Remove the power steering fluid reservoir cap.
    NOTE: If the air is not purged from the power steering system correctly, premature power steering pump failure may result. The condition can occur on pre-delivery vehicles with evidence of aerated fluid or on vehicles that have had steering component repairs.
  2. Install the Power Steering Evacuation Cap, Power Steering Fill Adapter Manifold and Vacuum Pump Kit as shown in the illustration.
  3. Close the Power Steering Fill Adapter Manifold control valve (fluid side).
    NOTE: The Power Steering Fill Adapter Manifold control valves are in the OPEN position when the points of the handles face the center of the Power Steering Fill Adapter Manifold.
  4. Open the Power Steering Fill Adapter Manifold control valve (vacuum side).
  5. Using the Vacuum Pump Kit, apply 68-85 kPa (20-25 in-Hg) of vacuum to the power steering system.
  6. Observe the Vacuum Pump Kit gauge for 30 seconds.
  7. If the Vacuum Pump Kit gauge reading drops more than 3 kPa (0.88 in-Hg), correct any leaks in the power steering system or the Power Steering Evacuation Cap, Power Steering Fill Adapter Manifold and Vacuum Pump Kit before proceeding.
  8. Slowly open the Power Steering Fill Adapter Manifold control valve (fluid side) until power steering fluid completely fills the hose and then close the control valve.
    NOTE: The Vacuum Pump Kit gauge reading will drop slightly during this step.
  9. Using the Vacuum Pump Kit, apply 68-85 kPa (20-25 in-Hg) of vacuum to the power steering system.
  10. Close the Power Steering Fill Adapter Manifold control valve (vacuum side).
  11. Slowly open the Power Steering Fill Adapter Manifold control valve (fluid side).
  12. Once power steering fluid enters the fluid reservoir and reaches the minimum fluid level indicator line on the reservoir, close the Power Steering Fill Adapter Manifold control valve (fluid side).
  13. Remove the Power Steering Evacuation Cap, Power Steering Fill Adapter Manifold and Vacuum Pump Kit.
  14. Install the reservoir cap.
  15. Start the engine and turn the steering wheel from stop-to-stop.
    NOTE: Do not hold the steering wheel against the stops for an extended amount of time. Damage to the power steering pump may occur.
    NOTE: There will be a slight drop in the power steering fluid level in the reservoir when the engine is started.
  16. Turn the ignition switch to the OFF position.
  17. Remove the reservoir cap and fill the reservoir with the specified fluid.
    NOTE: Do not overfill the reservoir.
  18. Install the reservoir cap.
