Inspection and Verification

CAUTION: Do not hold the steering wheel at the stops for an extended amount of time. Damage to the power steering pump will 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 tire pressure; refer to the Vehicle Certification (VC) label.
• Verify that all tires are sized to specification.
• Inspect the tires for damage or uneven wear.

3. Belt and Tensioner Check.
4. Fluid Level Check

• Verify that the power steering fluid level is at the full (F) mark. Add Motorcraft MERCON Multipurpose ATF 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.

• With the ignition switch at OFF, wipe off the power steering pump, power steering pressure hoses, power steering return hose, power steering fluid cooler (Coupe only) 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
8. Visually inspect for obvious signs of mechanical and electrical damage.

9. If an obvious cause for an observed or reported malfunction is found, correct the cause (if possible) before proceeding to the next step.
10. If the fault is not visually evident, determine the symptom and proceed to the following symptom chart. See: Symptom Related Diagnostic Procedures\Symptom Chart
