Drain and Refill System

The power steering fluid replacement procedure is a two-stage process: first, flushing the old fluid from the system with new fluid; and second, bleeding the system to remove any trapped air.

Remove or Disconnect
1. Raise the front end of the vehicle off the ground until the wheels are free to turn.
2. Remove the fluid return line at the pump reservoir inlet connector.
3. Plug the inlet connector port on the pump reservoir.
4. Position the fluid return line toward a large container in order to catch the draining fluid.
5. While a second person fills the reservoir with either standard power steering fluid or optional cold climate fluid, start and run the engine at idle.
6. Turn the steering wheel from stop-to-stop.

NOTICE: Do not hold the wheel against stops - while flushing the system. Holding steering wheel against wheel stops will cause high system pressure, overheating, and damage to the pump and or gear.

7. Continue draining until all of the old fluid is cleared from the power steering system. Addition of approximately 0.968 L (1 quart) of new fluid will be required to flush system.
8. Unplug pump reservoir inlet and reconnect return line.
9. Turn engine off, and fill reservoir to the "FULL COLD" mark.
10. Continue with following procedure, "Bleeding Power Steering System."
