Hose and gauge - power steering pressure test

CAUTION:

If power steering fluid comes into contact with the paintwork, the affected area must be immediately washed down with cold water.

  1. WARNING:

    Do not work on or under a vehicle supported only by a jack. Always support the vehicle on safety stands.

    Raise and support the vehicle.
  2. Disconnect the battery ground cable. For additional information, refer to: Specifications (414-00 Battery and Charging System - General Information, Specifications).
  3. E58865
    Siphon the fluid from the power steering reservoir.
      • Remove the filler cap.
  4. E46253
    Remove the front LH splash shield.
      • Remove the 4 clips.
  5. E85740
    Release the steering gear high-pressure line.
      • Remove the bolt.
  6. Remove the front LH fender splash shield. For additional information, refer to: Fender Splash Shield (501-02 Front End Body Panels, Removal and Installation).
  7. CAUTIONS:

    • Before disconnecting any components, make sure the area is clean and free from foreign material. ​When ​disconnected all openings must be sealed.

    • Make sure that the area around the component is clean and free of foreign material.

    E86422
    Disconnect the power steering pump supply hose.
      • Release the clip.
      • Position a container to collect the fluid.
  8. CAUTION:

    Make sure that the area around the component is clean and free of foreign material.

    E86423
    Disconnect the power steering pump high-pressure line.
      • Remove the bolt.
  9. Install the special tools.
      • Tie the pressure gauge aside.
  10. NOTE:

    Remove and discard the blanking caps.

    Connect the power steering pump supply hose.
      • Secure with the clip.
  11. Fill the power steering reservoir.
  12. Connect the battery ground cable. For additional information, refer to: Specifications (414-00 Battery and Charging System - General Information, Specifications).
  13. NOTES:

    • Make sure the steering components and test equipment are free from leaks.

    • Maintain the maximum fluid level during the test.

    • Make sure the steering is in the straight ahead position.

    • Under no circumstances must the low pressure spigot be removed from the steering pump.

    With the test valve open start the engine.
      • Start the engine and turn steering fully lock to lock, stop the engine.
      • Top-up the power steering fluid reservoir.
      • Install the reservoir filler cap.
  14. For correct power steering pressures, refer to the steering specification section.For additional information, refer to: Specifications (211-02 Power Steering, Specifications).
  15. CAUTION:

    Do not hold steering at full lock for longer than 10 seconds.

    With the engine at idle, slowly turn the steering wheel and hold on full lock.
      • Record the pressure reading.
  16. Repeat the above procedure for the other side.
      • Record the pressure reading.
  17. With the engine at idle, release the steering wheel. The pressure should be, at or below, the pressure specified.
  18. Pressure outside this tolerance, indicates a fault.
  19. CAUTION:

    Pump damage will occur if test valve is closed for longer periods.

    To determine if the fault is in the steering pump or the steering rack, close the test valve for a maximum of 5 seconds.
  20. If the pressures recorded fall outside the given values, replace the power steering pump.
  21. If the maximum pump pressure is correct, check the hoses for correct routing and condition, if correct suspect the steering gear.
  22. On completion of the test stop the engine, disconnect the battery ground cable and siphon the steering fluid from the reservoir.
  23. CAUTIONS:

    • Before disconnecting any components, make sure the area is clean and free from foreign material. ​When ​disconnected all openings must be sealed.

    • Make sure that the area around the component is clean and free of foreign material.

    Disconnect the power steering pump supply hose.
      • Release the clip.
  24. Disassemble the test equipment.
  25. Connect the power steering pump high-pressure line.
      • Tighten the bolt to 25 Nm (18 lb.ft).
  26. NOTE:

    Remove and discard the blanking caps.

    Connect the power steering pump supply hose.
      • Secure with the clip.
      • Remove the container.
  27. Secure the steering gear high-pressure line.
      • Tighten the bolt to 10 Nm (7 lb.ft).
  28. Install the front LH splash shield.
      • Install the clips.
  29. Install the front LH fender splash shield. For additional information, refer to: Fender Splash Shield (501-02 Front End Body Panels, Removal and Installation).
  30. Connect the battery ground cable.
  31. Fill and bleed the power steering system. For additional information, refer to: Power Steering System Filling and Bleeding (211-00 Steering System - General Information, General Procedures).
