INSPECTION AND ADJUSTMENT
BLEEDING OF POWER STEERING SYSTEM
1. Check the fluid level, and add fluid if necessary.
2. Turn the steering wheel fully in both directions 5
times (engine not running).
3. Recheck the fluid level. If the level has lowered,
add fluid, and repeat from step 1.
86U10X-021
4. Start the engine, and run it at idle.
5. Turn the steering wheel fully in both directions 5
times to bleed air from the system.
6. Check that the fluid is not foamy and the fluid lev-
el has not lowered.
If a problem is found, add fluid as necessary and
repeat from step 5.
Note
If bleeding is not done completely, the follow-
ing problems may appear:
• Foamy fluid on level gauge.
• Noise from power steering oil pump.

POWER STEERING PRESSURE
1. Disconnect the high-pressure hose of the gear
housing side, and attach the SST.
Tightening torque:
39—49 N-m (4.0—5.0 m-kg, 29—36 ft-lb)
2. Bleed air from the system.
3. Open the gauge valve fully, then start the engine
and turn the steering wheel fully left and right to
raise the fluid temperature to 50—60°C
(122—140°F)
4. To measure the fluid pressure generated by the
oil pump, close the gauge valve completely and
increase the engine speed to 1,000—1,500 rpm.
If the fluid pressure is low, replace the oil pump
assembly.
Warning
If the valve is left closed for more than 15 sec-
onds, the fluid temperature will increase ex-
cessively and adversely affect the oil pump.

(75—80 kg/cm2, 1,066—1,138 psi)
4WS
Front 8,093—8,829 kPa
(82.5—90.0 kg/cm2, 1,173—1,280 psi)
Rear 7,112—7,848 kPa
(72.5—80.0 kg/cm2, 1,031—1,138 psi)
To measure the fluid pressure generated at the
gear housing, first open the gauge valve complete-
ly, increase the engine speed to 1,000—1,500
rpm, and then turn the steering wheel fully to the
left and right.
Warning
If the steering wheel is kept in the fully turned
position for more than 15 seconds, the fluid
temperature will rise excessively.

If the fluid pressure is low, repair or replace the gear
box.
6. Remove the gauge set, then tighten the high-
pressure hose to the specified torque.
Tightening torque:
31—36 Nm (3.2—3.7 m-kg, 23—27 ft-lb)
7. Bleed the air from the system. (Refer to page
