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 inHg). 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.
11. Start the engine. Allow the engine to idle.
