6.

Exhaust the air in steering system:

(a)

Loosen the bleeding plug;

(b)

Screw up the bleeding plug when there is no air bubble

exhausted from the pipeline.

Notice: take care not let the ethane pipe slide from the

bleeding plug, because the liquid is high in temperature

and pressure.

7.

Check to see whether there is air bubble or turbidities

in the oil cup, and ensure the liquid level will not

exceed the max value when the engine stops,

Measure the liquid height under the condition of engine running,

then turn off the engine and measure the liquid height again.

In case any problem is found, repeat the approaches of (5) and

(6) in Power Steering Liquid Change. If the problem still

exists, repair the power steering oil pump.
