AIR BLEEDING
Caution
l Do not start the engine.
l Jack up the front of the vehicle.
1. Check the fluid level. (Refer to page N-27.)
2. Turn the steering wheel fully to the left and right several times
with the engine not running.
3. Recheck the fluid level. If the level has lowered, add fluid.
4. Repeat steps 2 and 3 until the fluid level stabilizes.
5. Start the engine and let it idle.
6. Turn the steering wheel fully to the left and right several
times.
7. Check that the fluid is not foamy and that the fluid level has
not dropped.
8. Add fluid if necessary and repeat steps 6 and 7.
STEERING WHEEL AND COLUMN
Inspection (On-vehicle)
Steering wheel effort
1. With the vehicle on a hard, level surface, put the wheels
in the straight-ahead position.
2. Start the engine and warm the power steering fluid to
50-60°C
(122-14OOF) by turning the steering: wheel fully
left and right several times.
3. With the engine running at idle speed, attach a pull scale
to the outermost point of the steering wheel spoke. Then,
starting with the wheels in the straight-ahead position, check
the steering effort required to turn the steering wheel to the
left and to the right.
4. If the measured effort exceeds specification, check the fol-
lowing: fluid level, air in system, fluid leakage at hose or con-
nections, function of P/S oil pump and gearbox, and tire
pressures.
Steering wheel effort: 29 N (3.0 kg, 6.6 lb) or less 03UONX-033

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.
