Power Steering System Bleeding
WARNING:
The fluid level should be checked with engine off to prevent injury from moving components.
CAUTION:
If the air is not purged from the power steering system correctly, pump failure could result.
NOTE:
Be sure the vacuum tool used in the following procedure is clean and free of any fluids.
- Check the fluid level. As measured on the side of the reservoir, the level should indicate between "ADD" and "FULL COLD" when the fluid is at normal ambient temperature. Adjust the fluid level as necessary. Refer to: POWER STEERING FLUID LEVEL CHECKING .
- Tightly insert special tool # 9688A, (Power Steering Pump Cap Adapter) (4) into the mouth of the reservoir.CAUTION:
Failure to use a the vacuum pump reservoir (1) may allow power steering fluid to be sucked into the hand vacuum pump.
1 - Reservoir 2 - Hand Vacuum Pump 3 - Power Steering Reservoir 4 - Power Steering Cap Adapter - Attach special tool # C-4207-A, (Hand Vacuum Pump) or equivalent, with the reservoir attached to the power steering cap adapter.CAUTION:
Do not run the engine while vacuum is applied to the power steering system. Damage to the power steering pump can occur.
NOTE:When performing the following step make sure the vacuum level is maintained during the entire time period.
- Using the hand vacuum pump, apply 68-85 kPa (20-25 in. Hg) of vacuum to the system for three minutes.
- Slowly release the vacuum and remove the special tools.
- Adjust the fluid level as necessary.
- Start the engine and cycle the steering wheel lock-to-lock three times.NOTE:
Do not hold the steering wheel at the stops.
- Stop the engine and check for leaks at all connections.
- Check for any signs of air in the reservoir and check the fluid level. If air is present, repeat the procedure as necessary.
