Hydraulic System Bleeding

CAUTION: If power steering system has been serviced, an accurate fluid reading cannot be obtained unless air is bled from steering system. Air in the fluid may cause pump cavitation noise and may cause pump damage over a period of time. When adding fluid or making a complete fluid change, always use proper power steering fluid. Failure to use proper fluid will cause hose and seal damage and fluid leaks. Verify that hoses do not touch any other part of vehicle and that all hose connections are tight.
  1. Remove power steering reservoir cap. Inspect fluid level. Add fluid, if necessary. Attach Power Steering Bleeder Adapter (J-43485) to Mity Vac (J-35555), or equivalent. Place the Power Steering Bleeder Adapter on reservoir filler neck. Apply a vacuum of 20 in Hg. Wait 5 minutes. Typical vacuum drop is 2-3 in Hg.
  2. Reinstall pump reservoir cap. Start engine and allow to idle. Turn engine off. Inspect fluid level. Add fluid, if necessary.
  3. Start engine and allow to idle. Partially raise and support vehicle in order to allow front tires and wheel to turn freely. Verify front tires and wheels are in straight-ahead position. DO NOT turn steering wheel to lock position. Turn steering wheel 180-360 degrees in both directions 5 times. Repeat procedure until fluid is purged of air and fluid is Red in appearance.
