Power steering Pump Bleeding Procedure:-----

1. Use clean, new power steering fluid type only.
2. Hoses touching the frame, body or engine may cause system noise. Verify that the hoses do not touch any other part of the vehicle.
3. Loose connections may not leak, but could allow air into the steering system. Verify that all hose connections are tight.
   
   NOTE

   Power steering fluid level must be maintained throughout bleed procedure.
4. Fill pump reservoir with fluid to minimum system level, FULL COLD level, or middle of hash mark on cap stick fluid level indicator.
5. Raise the vehicle until the front wheels are off the ground.
6. Key on engine OFF , turn the steering wheel from stop to stop 12 times. Vehicles equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.
7. Verify power steering fluid level per operating specification.
8. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
9. Verify the fluid level. Repeat the bleed procedure, if necessary.
