Note:
• Use clean, new power steering fluid type only. See the Maintenance and Lubrication subsection for fluid specifications.
• Hoses touching the frame, body or engine may cause system noise. Verify that the hoses do not touch any other part of the
vehicle.
• 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.
Fill pump reservoir with fluid to minimum system level, FULL COLD level, or middle of hash mark on cap stick fluid level indicator.

stops.
Verify power steering fluid level per operating specification. Refer to
Checking and Adding Power Steering Fluid
.
5.
Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
