Flushing Procedure
WARNING:
Do not mix oil types. Any mixture or any unapproved oil could lead to seal deterioration and leaks. A leak could ultimately cause loss of fluid, which could result in a power steering assist.
- Remove the fuse pump relay located in the battery junction box to disable the vehicle from starting.
- Disconnect the power steering return hose.
- Compress and move the hose clamp.
- Disconnect the power steering return hose and plug the fitting into the reservoir.
- Attach an extension hose between the power steering hose and an empty container.
- Raise the front wheels off the floor.
- Fill the power steering reservoir.
- Turn the steering wheel from stop-to-stop while cranking the engine. Refill the power steering pump as necessary until the fluid exiting the extension hose is clear.
- Lower the vehicle.
- Remove the extension hose and connect the power steering return hose to the power steering pump reservoir.
- Remove the plug and connect the power steering return hose.
- Compress and move the clamp into place.
- Fill the power steering fluid reservoir to the appropriate level.
- Install the fuel pump relay.
- Start the engine and turn the steering wheel from stop-to-stop.
- Check the power steering fluid level.
- Clear the diagnostic trouble codes (DTCs).
- Run the vehicle and check the system for leaks.
CAUTION:
Do not operate the starter motor for more than 10 seconds at a time. Damage to the starter motor could result.
CAUTION:
Do not overfill the power steering fluid reservoir.
CAUTION:
Do not hold at the stop for more than five seconds; damage to the pump can occur.
NOTE:
If power steering is noisy and accompanied by evidence of aerated fluid, it will be necessary to purge the power steering system.
