Power Steering System Flushing

Power Steering System Flushing





NOTICE: Do not mix oil types. Any mixture or any unapproved oil can lead to seal deterioration and leaks. A leak can ultimately cause loss of fluid, which may result in a loss of power steering assist.

1. Remove the power steering fluid reservoir cap.

2. Using a suitable suction device, remove the power steering fluid from the reservoir.

3. Disconnect the power steering fluid return hose from the reservoir.
- Remove the clamp.

4. Plug the power steering fluid reservoir inlet port.

5. Attach an extension hose to the power steering return hose.

6. NOTE: Do not reuse the power steering fluid that has been flushed from the power steering system.

Place the open end of the extension hose into a suitable container.

7. NOTE: Do not overfill the reservoir.

Check the power steering fluid level and add the specified fluid as necessary.

8. NOTICE: Do not allow the power steering pump to run completely dry of power steering fluid. Damage to the power steering pump may occur.

Start the engine while simultaneously turning the steering wheel to lock and then immediately turn the ignition switch to the OFF position.

9. NOTE: Avoid turning the steering wheel without the engine running as this may cause air to be pulled into the steering gear.

NOTE: Do not overfill the reservoir.

Check the power steering fluid level and add the specified fluid as necessary.

10. Repeat Steps 8 and 9, turning the steering wheel in the opposite direction each time, until the fluid exiting the power steering fluid return hose is clean and clear of foreign material.

11. Remove the extension hose from the power steering return hose.

12. Remove the plug from the power steering fluid reservoir inlet port.

13. Install the power steering return hose to the reservoir.
- Install the clamp.

14. NOTE: It is necessary to properly fill the power steering system to remove any trapped air and completely fill the power steering system components. If, after properly filling the power steering system, there is power steering noise accompanied by evidence of aerated fluid and there are no fluid leaks, it may be necessary to purge the power steering system.
