- Disable the ignition by disconnecting the ignition module or disconnecting the camshaft position sensor.
- Raise and safely support the vehicle so the front wheels are off the floor.
- Place jackstands under the front of the vehicle.
- Fill the power steering fluid reservoir.
- Crank the engine with the starter motor and add fluid until the level remains constant.
While cranking the engine, rotate the steering wheel from lock-to-lock.
NOTEThe front wheels must be off the floor during lock-to-lock rotation of the steering wheel. Do not hold the steering wheel on the stops.
- Check the fluid level and add fluid, if necessary.
- Enable the ignition system. Start the engine and allow it to run for several minutes.
- Rotate the steering wheel from lock-to-lock.
- Stop the engine and check the fluid level. Add fluid, if necessary.
If air is still present in the system, purge the system of air using Power Steering Air Evacuator 021-00014 or equivalent, as follows:
- Make sure the power steering pump reservoir is full to the COLD FULL mark on the dipstick or to just above the minimum indication on the reservoir.
- Tightly insert the rubber stopper of the air evacuator assembly into the pump reservoir fill neck.
- Apply 20 inch Hg maximum vacuum on the pump reservoir for a minimum of 3 minutes with the engine idling. As air purges from the system, vacuum will fall off. Maintain adequate vacuum with the vacuum source.
- Release the vacuum and remove the vacuum source. Fill the reservoir to the COLD FULL mark or to just above the minimum indication on the reservoir. Install the evacuator tool again.
- With the engine idling, apply 20 inch Hg vacuum to the pump reservoir. Slowly cycle the steering wheel from lock-to-lock every 30 seconds for approximately 5 minutes. Do not hold the steering wheel on the stops while cycling. Maintain adequate vacuum with the vacuum source as the air purges.
- Release the vacuum and remove the vacuum source. Add fluid, if necessary.
- Start the engine and cycle the steering wheel. Check for oil leaks at all connections. In severe cases of aeration, it may be necessary to repeat the procedure.
- Remove the jackstands.
- Lower the vehicle.
- Check the power steering system for proper operation.
