POWER STEERING FLUID
On-vehicle Inspection
Inspection of fluid level
Caution
l Add only the specified power steering fluid.
1. Verify that the fluid level is between the H and L marks.
2. Add or remove fluid if not within specification.
Inspection of fluid leakage
Start the engine. Turn the steering wheel fully left and right to apply fluid pressure; then check for fluid leakage.
Caution
+ To prevent damage, do not keep the steering wheel in the fully turned position for more than
15 seconds.
Note
l The points where fluid leakage may occur are indicated by the arrows in the figure.

Inspection of fluid pressure
1. Assemble the SST as shown in the figure.
Tightening torque:
39-49 Nern (4.0-5.0 m-kg, 29-36 ft-lb)
2. Disconnect the pressure hose on the oil pump side, and
attach the SST.
Note
l Before disconnecting the hose, make marks at the
connections for proper reinstallation.
3. Bleed the air from the system. (Refer to page N-26.)
4. Open the gauge valve fully. Start the engine and turn the
steering wheel fully left and right to raise the fluid tempera-
ture to 50-60°C (122-14OOP).
5. Close the gauge valve completely. Increase the engine
speed to 1,000-l ,500 rpm and measure the fluid pres-
sure generated by the oil pump. If the pressure is below
specification, replace the oil pump assembly.
Oil pump fluid pressure:
7,356 kPa (75 kg/cm2, 1,067 psi)
Caution
l If the valve Is left closed for more than 15 seconds,
the fluid temperature will increase excessively and
adversely affect the oil pump.
6. Open the gauge valve fully again and increase the engine
speed to l,OOO-1,500 rpm.
7. Turn the steering wheel fully to the left and right and meas-
ure the fluid pressure generated by the gear housing. If the
pressure is below specification, replace the gear housing
assembly.
Gear housing fluid pressure:
7,356 kPa (75 kg/cm2, 1,067 psi)
Caution
l If the steering wheel is kept in the fully turned po-
sition for more than 15 seconds, the fluid tempera-
ture will rise excessively.

Removal / Installation
1. Loosen the wheel lug nuts.
2. Jack up the front of the vehicle and support it with safety stands.
3. Remove the wheels.
4. Remove in the order shown in the figure, referring to
Removal Note.
5. Install in the reverse order of removal, referring to Installation Note.
6. After installation, bleed air from the steering system and adjust the toe-in if necessary. (Refer to Section R.)
