Power Steering Bleeding: Service and Repair

Power Steering System Bleeding

Note:
* Use clean, new power steering fluid type only. Refer to Fluid and Lubricant Recommendations (USA and Canada) (Maintenance).
* Hoses touching the frame, body or engine may cause system noise. Verify that the hoses do not touch any other part of the vehicle.
* Loose connections may not leak, but could allow air into the steering system. Verify that all hose connections are tight.
* Maintain the power steering fluid level throughout the bleed procedure.

1. With the engine OFF, fill the pump reservoir to the MAX mark on capstick fluid level indicator.
2. Raise the vehicle until the front wheels are off the ground. Refer to Lifting and Jacking the Vehicle (Service and Repair).
3. Start the engine and turn the steering wheel from stop to stop 4 times.
4. Verify power steering fluid level. Refer to Checking and Adding Power Steering Fluid (Checking and Adding Power Steering Fluid).
5. Rotate steering wheel from left to right another 8 times. Check for signs of cavitation or fluid aeration (pump noise/whining).
6. Verify the fluid level. Repeat the bleed procedure, if necessary.
