Refilling & Bleeding System

  1. Fill pump reservoir to proper level. Start engine and run momentarily. Stop engine and recheck fluid level. Add fluid (if necessary). Repeat procedure until fluid level remains constant after running engine.
  2. Raise and support vehicle so front wheels are off ground. Start engine. Turn steering wheel from side to side several times (without hitting stops). Do not hold wheel in full left or right position. Fluid level should remain above pump inlet in reservoir.
  3. Return wheels to center position and operate engine for 2-3 minutes. Road test vehicle and recheck fluid level. All air should be eliminated to obtain normal steering.
    NOTE: Abnormal noise originating from the power steering system may be caused by air trapped in the system. Rotunda Vacuum Tester (021-00014) and the following procedure are designed to eliminate this condition.
  4. Carefully remove pump filler adapter and dipstick. Check and fill reservoir to "COLD" mark. Disconnect ignition coil lead and raise from wheel off of ground.
  5. Crank engine while cycling steering wheel. DO NOT hold wheel on stops. Add fluid if necessary. Attach coil lead and install evacuation tool onto reservoir.
  6. Start engine and apply 15 in. Hg on reservoir for approximately 3 minutes with engine idling. As air is purged from system, vacuum will decrease. Maintain sufficient vacuum with vacuum source.
  7. Release vacuum and check fluid level. Install filler adapter assembly and dipstick. Start engine and turn wheel from stop to stop while inspecting for leads. If condition is severe, repeat procedure until all air is removed. Lower vehicle and road test.
