Power Steering Bleeding: Service and Repair
Air Bleeding Hydraulic System
Incomplete air bleeding causes the following. When this happens, bleed air again.
^
Generation of air bubbles in reservoir tank.
^
Generation of 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.
1. 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 low level line. Check tank frequently and add fluid as needed.
2. Run engine at idle speed. Turn steering wheel fully to the right and then fully to the left, and keep for about three seconds. Then check whether a
fluid leakage has occurred.
3. Repeat the 2nd procedure several times at about three seconds intervals.
CAUTION: Do not hold steering wheel in the locked position more than 10 seconds. (Three is the possibility that oil pump may be damaged.)
4. Check generation of air bubbles and cloud in fluid.
5. If air bubbles and the cloud don't fade, stop engine, hold air bleeding until air bubbles and the cloud fade. Perform the 2nd and the 3rd procedures
again.
6. Stop engine, check fluid level.
