CAUTION: Do not hold the steering wheel (3600) at the stops for an extended amount of time. Damage to the power steering pump (3A674) 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 the tire pressure. 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 indicated range, hot forthe 3.8L engine and cold for the 4.6L engine. Add Motorcraft MERCON Multi-PurposeATF XT-2-QDX or MERCON equivalent.

5. Air Bleeding

  • Verify that there is no air in the power steering system. Run the engine (6007) until itreaches normal operating temperature. Turn the steering wheel to the left and rightseveral times without hitting the stops. If any air bubbles are present, refer to Purging-CII Power Steering Pump or Purging-CIII Power Steering Pump in this section.
