Air Bleeding ▶
Lift up the vehicle very carefully.
Turn the steering wheel to its both ends
several times and add the oil up to MAX
line in the steering oil reservoir.
Periodically crank the starting motor and
turn the steering wheel to its both ends
without any interruption.
Check the oil level again. If the oil level is
fluctuated, repeat the procedures from
step 3 to step 5.
Start the engine.
Turn the steering wheel to its both ends
until any bubble can be found in the
steering oil reservoir.
Perform the test drive and check the
steering wheel for normal operation and
noise.
If the oil level abruptly goes up, bleed the
air from the system again. 1.

The air bleeding should be done after
servicing the power steering system and when
the difference between two measurements
(cooled and normal temperature) is
prominent.

If the air bleeding is not properly
performed, the life span of the power
steering pump may be shortened. -

Oil Pump Pressure Check ▶
Unscrew the pressure line fitting in power
steering pump.
Install the pressure gauge between the
power steering pump and the power
steering oil pressure line.
Place the shift lever to neutral position.
Apply the parking brake.
Open the valve in pressure gauge. Start
the engine and let it run at idle speed.
Turn the steering wheel several times so
that the oil temperature reaches to normal
operating level. 1.

Before checking the pressure, check the oil
level and belt tension. Prepare the empty
container to collect the spilled oil during the
service. Check the oil pump pressure to locate any
defect in oil pump.
Fully close the valve in pressure gauge and
measure the oil pressure. 6.
Relief pressure
90 ± 3 bar

To prevent internal damage, do not close
the gauge valve over 10 seconds.
Keep the oil temperature at proper range. -

Measure the oil pressure with the gauge
valve fully open. 7.
Pressure at no load
3 to 5 bar
If the pump pressure is in specified range,
the pump is normal. If not, replace the
power steering pump 8.
Turn the steering wheel righ or left until it
stops with the engine idling ans valve fully
open. 9.

To prevent the internal damage, do not
close the gauge valve for over 10
seconds.
Keep the oil temperature at proper range. -

The steering pump is driven by the engine power through a belt. This pump circulates the power
steering oil from the reservoir -> steering pump -> oil supply pipe -> steering gear box -> oil
