Air Bleeding

Fill the power steering fluid reservoir up to the "MAX"position with specified fluid.
NOTE:
1. When bleeding fluid, replenish the fluid so that the level never falls below the bottom of the filter.
2. If air bleeding is done while the vehicle is idling, the air will be broken up and absorbed into the fluid. Be sure to do the bleeding only while cranking.
Jack up the front wheels.
Disconnect the ignition coil high tension cable, and then, while operating the starter motor intermittently (for 15 to 20 seconds), turn the steering wheel to the limit of left and then to the limit of right five or six times.
Connect the high tension cable, and then start the engine (idling).
Turn the steering wheel to the left and then to the right, until there are no air bubbles in the oil reservoir.
NOTE: Do not hold the steering wheel turned to either side for more than ten seconds.
Confirm that the fluid is not milky, and that the level is between "MAX"and "MIN" marks on the reservoir.
If the fluid level changes up and down considerably when the steering wheel is turned left and right or fluid overflows from the reservoir when the engine is stopped, air bleeding should be done again.

NOTE:

If the fluid level varies 5mm (0.2 in.) or more, bleed the system again.

If the oil level changes up and down when the steering wheel is turned or the fluid overflows from the reservoir when the engine is stopped, further air bleeding is required. If the air isn't removed, it can cause cavitation in the pump, noise and may damage the pump.
