Power Steering Hydraulic System Bleeding

PROCEDURE

1. Disconnect the high-tension lead from the ignition coil. Crank the engine with the starter intermittently for 15–20 s and turn the steering wheel lock to lock 5–6 times.

During bleeding, keep adding fluid so that the level in the reservoir does not drop below the filter installation point.
If bleeding is performed while the crankshaft is not rotating, air will dissolve back into the fluid. Make sure bleeding is performed while the crankshaft is being rotated.

2. Connect the high-tension lead to the ignition coil, start the engine and let it run at idle speed.
3. Turn the steering wheel from lock to lock several times. Check that the fluid does not foam and that its level has not dropped.

To prevent damage, do not hold the steering wheel at full lock for more than 10 seconds.

4. Check that the fluid is not milky in color and that its level is between the marks on the dipstick.
5. Check that the fluid level changes slightly when the steering wheel is turned to the left and to the right.

If the fluid level changes significantly, repeat the power steering hydraulic system bleeding procedure.
If the fluid level rises suddenly after the engine is stopped, air is still present in the system.
If there is air in the power steering hydraulic system, abnormal noise will be heard when the pump operates. Air in the system will shorten the service life of the pump and other components.
