Bleed Procedure

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.

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

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

  • Verify that all of the hose connections are tight.
