AIR BLEEDING

A3U061201036W02

1. Inspect the fluid level. (See 06–12–3 Fluid Level Inspection.)
2. Jack up the front of the vehicle and support it on safety stands.
3. Turn the steering wheel fully to the left and right several times with the engine not running.
4. Reinspect the fluid level.

•

If it has dropped, add fluid.

5. Repeat Steps 3 and 4 until the fluid level stabilizes.
6. Lower the vehicle.
7. Start the engine and let it idle.
8. Turn the steering wheel fully to the left and right several times.
9. Verify that the fluid is not foamy and that the fluid level has not dropped.

•

Add fluid as necessary and repeat Steps 8 and 9.

Fluid Level Inspection

1. Inspect the power steering fluid level.

•

Add fluid to the specified level as necessary.

Fluid specification

ATF M-

III

or equivalent (e.g. Dexron

®

III

)

Fluid Leakage Inspection

Caution

••••

If the steering wheel is kept in the fully turned position for more than 5 seconds, the fluid
temperature will rise excessively and adversely affect the oil pump.

1. Start the engine and let it idle. Turn the steering wheel fully to the left and right to apply fluid pressure.

Note

•

The points where fluid leakage may occur are indicated in the figure.

2. Inspect for fluid leakage.

•

If fluid leakage is found, replace related pipe
or hose.

Fluid Pressure Inspection

1. Assemble the SSTs as shown in the figure.
2. Disconnect the pressure pipe from the oil pump,

and connect the SSTs.

Tightening torque

30—44 N·m {3.0—4.5 kgf·m, 22—32 ft·lbf}

3. Bleed the air from the system.
4. Open the gauge valve fully. Start the engine and

turn the steering wheel fully left and right to raise
the fluid temperature to 50—60

°°°°

C {123—140

°°°°

F}.

Caution

••••

If the valve is left closed for more than 5
seconds, the fluid temperature will rise
excessively and adversely affect the oil
pump.

5. Close the gauge valve completely. Increase the

engine speed to 1,000—1,500 rpm and measure
the fluid pressure generated by the oil pump.

•

If the pressure is not within the specification,
repair or replace the oil pump component.

Oil pump fluid pressure

8.34—8.82 MPa {85.0—90.0 kgf/cm

2

, 1,209—

1,279 psi}

Caution

••••

If the steering wheel is kept in the fully
turned position for more than 5 seconds,
the fluid temperature will rise excessively
and adversely affect the oil pump.

6. Open the gauge valve fully and increase the

engine speed to 1,000—1,500 rpm.

7. Turn the steering wheel fully to the left and right,

then measure the fluid pressure generated at the
gear housing.

•

If the pressure is not within the specification,
repair or replace the steering gear
component.

Gear housing fluid pressure

8.34—8.82 MPa {85.0—90.0 kgf/cm
