POWER STEERING FLUID INSPECTION

id061400800500

Fluid Level Inspection

1. Inspect the power steering fluid level.

• Add fluid to the specified level as necessary.

Power steering fluid type

ATF M‐III or equivalent (e.g. Dexron^®II)

Power steering fluid capacity (approx. quantity)

1.1 L {1.2 US qt, 1.0 lmp qt}

Fluid Leakage Inspection

1. Start the engine and let it idle.

2. Turn the steering wheel fully to the left and right to apply fluid pressure.

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.

3. Inspect for fluid leakage at the points indicated in the figure.

• If fluid leakage is found, replace related parts.

Fluid Pressure Inspection

1. Assemble the SSTs as shown in the figure.

2. Mark both hose connections to ensure that the hose is reinstalled in its original position.

3. Disconnect the pressure pipe from the oil pump or steering gear, and connect the SSTs.

Tightening torque

31.4—47.0 N·m {3.21—4.79 kgf·m, 23.2—34.6 ft·lbf}

4. Connect the SSTs (49 1232 670B and 49 H002 671) to the SST (49 B032 304 or 49 G032 3A4A)

5. Bleed the air from the system. (See AIR BLEEDING.)

6. Open the gauge valve fully.

7. Start the engine and turn the steering wheel fully left and right to raise the fluid temperature to 50—60 °C {122—140 °F}.

Caution

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

8. 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

F2, G6: 8.8—9.3 MPa {89.8—94.9 kgf/cm², 1277—1348 psi}

WLT-1, WLT-2, WL-3, WL-C, WE-C: 9.3—9.8 MPa {94.9—99.9 kgf/cm², 1348—1421 psi}

Caution

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

9. Open the gauge valve fully and increase the engine speed to 1,000—1,500 rpm

10. Turn the steering wheel fully to left and right and 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

9.30—9.79 MPa {94.8—99.8 kgf/cm², 1348—1419psi}

11. Remove the SSTs. Install and tighten the pressure pipe to the specified torque.

Tightening torque

31.4—47.0 N·m {3.21—4.79 kgf·m, 23.2—34.6 ft·lbf}

12. Bleed the air from the system.
