Air Bleeding Hydraulic System

WARNING: This page is about a different car, the 2013 Nissan Armada. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Incomplete air bleeding causes the following. When this happens, bleed air again.

Air bubbles in reservoir tank.
Clicking noise in oil pump.
Excessive buzzing in oil pump.

NOTE: When vehicle is stationary or while steering wheel is being turned slowly, some noise may be heard from oil pump or gear. This noise is normal and does not affect any system.

Stop engine, and then turn steering wheel fully to right and left several times.
CAUTION: Do not allow steering fluid reservoir tank to go below the MIN level line. Check tank frequently and add fluid as needed.
Run engine at idle speed. Turn steering wheel fully right and then fully left, hold for about three seconds. Then check for fluid leakage.
Repeat step 2 several times at about three second intervals.
CAUTION: Do not hold steering wheel in the locked position for more than 10 seconds. (There is the possibility that oil pump may be damaged.)
Check for air bubbles or cloudy fluid.
If air bubbles or cloudiness still exists, stop engine, perform steps 2 and 3 again until air bubbles or cloudiness does not exist.
Stop engine, check fluid level.
