Bleeding the Power Steering System

Bleeding the Power Steering System

^ Tools Required
- J 35555 Metal Mityvac
- J 43485 Power Steering Bleeder Adapter

1. Verify that the hoses do not touch any other part of the vehicle.

Important: Hoses touching the frame, body, or engine may cause system noise.

2. Verify that all hose connections are tight.

Important: Loose connections may not leak, but could allow air into the steering system.






3. Remove the pump reservoir cap.

Notice: If the power steering system has been serviced, an accurate fluid level reading cannot be obtained unless air is bled from the steering system. The air in the fluid may cause pump cavitation noise and may cause pump damage over a period of time.

Important: Maintain the fluid level throughout the bleed procedure.


4. Fill the pump reservoir with fluid to the FULL COLD level.

Important: Use clean, new power steering fluid only.






5. Attach the J 43485 to the J 35555 or equivalent.
6. Place the J 43485 on or in the pump reservoir filler neck.
7. Apply a vacuum of 68 kPa (20 in Hg) maximum.
8. Wait 5 minutes. Typical vacuum drop is 7 - 10 kPa (2 - 3 in Hg). If the vacuum does not remain steady, refer to Excessive Vacuum Drop Diagnosis at the end of this procedure.
9. Remove the J 43485 and the J 35555.
10. Reinstall the pump reservoir cap.
11. Start the engine. Allow the engine to idle.
12. Turn off the engine.
13. Verify the fluid level. Repeat steps 11-13 until the fluid stabilizes.

14. Start the engine. Allow the engine to idle.

Important: Do not turn steering wheel to lock.

15. Turn the steering wheel 180-360 degrees in both directions 5 times.
16. Switch the ignition off.

17. Verify the fluid level.

Notice: When adding fluid or making a complete fluid change, always use the proper power steering fluid. Failure to use the proper fluid will cause hose and seal damage and fluid leaks.






18. Remove the pump reservoir cap.





19. Attach the J 43485 to the J 35555 or equivalent.
20. Place the J 43485 on or in the pump reservoir filler neck.
21. Apply a vacuum of 68 kPa (20 in Hg) maximum.
22. Wait 5 minutes.
23. Remove the J 43485 and the J 35555.
24. Verify the fluid level.





25. Reinstall the pump reservoir cap.
