Power Steering Bleeding: Service and Repair
Bleeding the Power Steering System
-
Tools Required
-
J 35555 Mity Vac
-
J 43485 Power Steering Bleeder Adapter
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.
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.
Important: Hoses touching the frame, body, or engine may cause system noise.
1. Verify that the hoses do not touch any other part of the vehicle.
Important: Loose connections may not leak, but could allow air into the steering system.
2. Verify that all hose connections are tight.
Important: Maintain the fluid level throughout the bleed procedure.
3. Remove the pump reservoir cap.
Important: Use clean, new power steering fluid only.
4. Fill the pump reservoir with fluid to the FULL COLD level.
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.
9. Remove the J 43485 and the J 35555.
10. Reinstall the pump reservoir cap.
