DIAGNOSIS

  1. Run the engine until it reaches normal operating temperature (the cooling fans cycle twice).
  2. Listen for abnormal noises from the power steering pump while the steering wheel is centered and not being turned.
    • If the pump whines, buzzes, or hums, go to REPAIR PROCEDURE.
    • If the noise is not coming from the pump, this service bulletin does not apply. Check for other possible causes of the noise.
  3. Inspect the power steering reservoir.
    Is there a white dot on the reservoir cover, with one of its ribs pointing toward the reservoir holder?

    • Yes – This vehicle already has the revised power steering reservoir. Continue with normal
      troubleshooting procedures.
    • No – Go to REPAIR PROCEDURE.

REPAIR PROCEDURE

  1.  Drain the power steering reservoir:
    • Remove the reservoir from its holder.
    • Raise the reservoir, and disconnect its return hose.
    • Drain the reservoir fluid into a suitable container. Take care not to spill any fluid on the body or other parts. Wipe off any spilled fluid immediately.
  2. Drain the fluid from the power steering system:
    • Connect a suitable diameter drain hose to the disconnected return hose.
    • Hold the end of the drain hose in a suitable container.
    • Start the engine, and run it at idle while you turn the steering wheel lock-to-lock several times.
    • When the fluid stops running out of the hose, shut off the engine.
    • Discard the used fluid.

POWER STEERING RESERVOIR

 

  1. Reinstall the return hose to the reservoir, then reattach the reservoir to its holder. Fill the reservoir to its upper level line with new power steering fluid.
  2. Bleed the air from the power steering system:
  3. Check the condition of the fluid in the reservoir:
    • If the fluid looks contaminated, dark, or discolored, repeat steps 1 thru 5.
    • If the fluid is clear, go to step 6.
  4. Place a suitable container under the vehicle to catch any fluid.
  5. Replace the power steering fluid reservoir:
    • Remove the reservoir from its holder.
    • Disconnect the return hose from the reservoir, and pour the fluid from the reservoir into a container.
    • Disconnect the outlet hose from the reservoir, and remove the reservoir.
    • Install a new reservoir in the reverse order of removal.
    • Fill the reservoir to its upper level line with new power steering fluid.

UPPER LEVEL LINE

 

  1. Start the engine, and run it at a fast idle. Turn the steering from lock-to-lock several times to bleed any air from the system.
  2. Recheck the fluid level in the reservoir, and add more if needed. Do not fill the reservoir beyond its upper level line.
