Service Adjustment Procedure
Steering Wheel Play Inspection
1.
Turn the steering wheel so that the front wheels can face straight ahead.
2.
Measure the distance that the steering wheel can be turned without moving the front wheels.

Standard value: 0 ~ 30mm (1.1811in.) or less

3.
If the play exceeds standard value, inspect the steering column, shaft, and linkages.
Checking Stationary Steering Effort
1.
Position the vehicle on a level surface and place the steering wheel in the straight ahead position.
2.
Start the engine and turn the steering wheel from lock to lock several times to warm up the power steering fluid.
3.
Attach a spring scale to the steering wheel. With the engine speed at 500 ~ 700 rpm, pull the scale and read it as soon as the tires begin to turn.

Standard value: 3.0kgf

4.
If the measured value exceeds standard value, inspect the power steering gear box and pump.
Power Steering Fluid Replacement
   
Always use genuine PSF. Using other type of power steering fluid or ATF can cause increased wear and poor steering in cold weather.
1.
Raise the reservoir and then disconnect the return hose to drain the reservoir. Be careful not to spill the fluid on the body and parts. Wipe off any spilled fluid immediately.
2.
Connect a tube of suitable diameter to the disconnected return hose, and put the hose end in a suitable container.
3.
Jack up the front wheels and turn the steering wheel from the lock to lock until fluid stops running out of the tube.
4.
Reconnect the return hose to reservoir.
5.
Fill the reservoir with new power steering fluid and then bleed air from the power steering system.
Air Bleeding
   
Always use genuine PSF. Using other type of power steering fluid or ATF can cause increased wear and poor steering in cold weather.
1.
Jack up the front wheels.
2.
Fill the reservoir with the power steering fluid up to the level of ''COLD MAX'' marked on the reservoir.

   
Be careful not to start the engine. Starting the engine before completing the steps 3 to 4 may cause an abnormal noise during power steering pump operation.
3.
Turn the steering wheel from lock to lock 5 ~ 6 times for 15 ~ 20 seconds.
4.
Crank the engine 1-2 times by turning the ignition key very quickly from the ''On'' position to the ''Start'' position without starting the engine.
5.
Turn the steering wheel from lock to lock 5 ~ 6 times for 15 ~ 20 seconds.
Start the engine and keep turning the steering wheel from lock to lock until air bubbles stop appearing in the reservoir with the engine idle.
6.
Check the color and level of the power steering fluid in the reservoir and then replenish the reservoir up to the ''COLD MAX'' level as required.
   
If the fluid level moves up and down when turning the steering wheel, the fluid overflows out of the reservoir when turning off the engine or the fluid is a white color, it indicates that air bubbles have not been removed sufficiently from the power steering system. Therefore, repeat the steps 5 through 6 as required.
Oil-Pump Pressure Test
1.
Disconnect the pressure tube from the power steering motor and then install the special tools between the motor and the pressure tube as illustrated below.

2.
Start the engine and turn the steering wheel several times so that the fluid temperature rises to approx. 50-60°C (122°F).
3.
Set the engine speed to approx. 600rpm.
4.
Close the shut-off valve of the special tools and measure the fluid pressure.

Relief pressure: 95 ~ 100 kgf/cm² (1351 ~ 1422 psi)

   
Do not keep the shut-off valve on the pressure gauge closed for longer than 10 seconds.
5.
Remove the special tools, and then connect the pressure tube to the pump by tightening the eye bolt.
6.
Bleed the power steering system.
