Service and Repair, Procedures




Power Steering System Bleeding

Important:
- Use clean, new power steering fluid type only. See: Maintenance
- 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.
- Power steering fluid level must be maintained throughout bleed procedure.

1. Fill pump reservoir with fluid to minimum system level, FULL COLD level, or middle of hash mark on cap stick fluid level indicator.

Important: With hydro-boost only, the oil level will appear falsely high if the hydro-boost accumulator is not fully charged. Do not apply the brake pedal with the engine OFF. This will discharge the hydro-boost accumulator.

2. If equipped with hydro-boost, fully charge the hydro-boost accumulator using the following procedure:
2.1Start the engine.
2.2Firmly apply the brake pedal 10-15 times.
2.3Turn the engine OFF.
3. Raise the vehicle until the front wheels are off the ground. See: Vehicle Lifting
4. Key on engine OFF, turn the steering wheel from stop to stop 12 times.
- Vehicle equipped with hydro-boost systems or longer length power steering hoses may require turns up to 15 to 20 stop to stops.
5. Verify power steering fluid level per operation specification. See: Power Steering Fluid
6. Start the engine. Rotate steering wheel from left to right. Check for sign of cavitation or fluid aeration (pump noise/whining).
7. Verify the fluid level. Repeat the bleed procedure, if necessary.

shawnrbaldwin :

shawnrbaldwin :
