Bleeding

Print

Perform the power steering pump bleeding procedure as necessary after replacing the steering gear, power steering oil pump or the steering fluid lines.

  1. Raise and safely support the front wheels of the vehicle.
  2.  
  3. Disconnect the ignition coil connectors. For more information, refer to the Engine Electrical Section.
    WARNING
    Perform air bleeding only while cranking the engine. Do not perform air bleeding while the engine is running. If you do so, air in the fluid will be increased and air bleeding will become more difficult. During air bleeding, refill the steering fluid so that the level never falls below the lower mark on the dipstick.

  4.  
  5. Turn the steering wheel all the way to the left and right five or six times while using the starter motor to crank the engine intermittently several times (for 15 to 20 seconds).
  6.  
  7. Connect the ignition coil connectors.
  8.  
  9. Start the engine and allow to idle.
  10.  
  11. Turn the steering wheel to the left and right until there are no air bubbles in the oil reservoir. Make sure that the fluid is not milky, and that the level is between the high and low dipstick marks.
  12.  
  13. Check that there is minimal change in the fluid level when the steering wheel is turned left and right.
    WARNING
    If the fluid level rises suddenly after the engine is stopped, the air has not been completely bled. If air bleeding is not complete, there will be abnormal noises from the pump and the flow-control valve, and this condition could reduce the life of the power steering components.

  14.  
  15. Make sure that the change in the fluid level is no more than 5 mm (0.2 inch) when the engine is stopped.

  17. If the change of the fluid level is 5 mm (0.2 inch) or more, the air has not been completely bled from the system. The air bleeding procedure must be repeated.
