SYSTEM BLEEDING



  1. Raise the front of the vehicle and support safely. This will minimize steering effort. Fill the power steering pump reservoir with the appropriate type of power steering fluid.
  2.  
  3. With the engine off, keep the reservoir full as an assistant turns the steering wheel from lock-to-lock several times. Stop with the steering system at one lock.
  4.  
  5. Start the engine and allow it to idle. Turn the wheel from lock-to-lock several times. Note the amount of air bubbles in the fluid. Repeat the procedure until no more air bubbles appear.
  6.
