CAUTION: Do not hold the steering wheel at the stops for an extended amount of time. Damage to the power steering pump can result.

NOTE: Make the following preliminary checks before repairing the steering system:

1. Verify the customer concern by operating the steering system.
2. Inspect Tires
^ Check the tire pressure. For additional information, refer to the Vehicle Certification (VC) label.
^ Verify that all tires are sized to specification.
^ Check the tires for damage or uneven wear.

3. Belt and Tensioner Check
4. Fluid Level Check
^ Verify that the power steering fluid level is within the appropriate hot or cold range on the dipstick. Add MERCON Multi-Purpose (ATF) Transmission Fluid XT-2-QDX or MERCON equivalent.

5. Air Bleeding
^ Verify that there is no air in the power steering system. Run the engine until it reaches normal operating temperature. Turn the steering wheel to the left and right several times without hitting the stops. If any air bubbles are present, refer to Purging.





6. External Leak Check
^ With the ignition switch at OFF, wipe off the power steering pump, power steering pressure hose, power steering return hose, power steering fluid cooler and hose assembly and steering gear.
^ With the engine running, turn the steering wheel from stop-to-stop several times. Do not hold steering wheel at stops. Check for leaks. Repair as necessary if leaks are observed.

7. Turning Effort Check
