POWER STEERING FLUID INSPECTION

id061400800500

## Fluid Level Inspection

1. Verify that the fluid level is between MAX and MIN of the reservoir tank when the engine is cold.

  • If the fluid level is not within the specification, adjust the fluid level by adding/draining the fluid.

Power steering fluid type

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

Power steering fluid capacity when reservoir tank is at maximum volume

  1.05 L {1.11 US qt, 0.92 Imp qt} (approximate quantity)

## Fluid Leakage Inspection

1. Start the engine and keep idling.

2. Turn the steering wheel fully to left or right, make the hydraulic pressure operate.

  Caution

  • Do not maintain the steering wheel fully turned for 5 s or more. It is possible that oil temperature can rise, and this will negatively affect the oil pump.

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

  • If fluid leakage is found, repair the related parts.

## Fluid pressure Inspection

1. Set the SSTs so that the valve of the SST faces toward the gear housing side as shown in the figure.

2. Remove the air cleaner. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [WITHOUT WU-TWC].) (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [WITH WU-TWC])

3. Disconnect the oil pump side joint of the pressure hose, connect the SST set in the Step 1.

Tightening torque

  29.4-44.1 N·m {3.00-4.49 kgf·m, 21.6-32.5 ft·lbf}

4. Bleed the air from the system.

5. Open the gauge valve fully.

6. Start the engine, turn the steering wheel to the left and right to make the power steering fluid rise to the suitable temperature (50-60 °C {122-140 °F}).

7. Close the gauge valve fully.

8. Increase the engine speed to 1,000-1,500 rpm, and measure the fluid pressure generated at the oil pump.

  • If it is less than the specification, replace the oil pump as a single unit.

  Caution

  • Do not maintain the gauge valve fully closed for 5 s or more. It is possible that oil temperature can rise, and this will negatively affect the oil pump.

Oil pump fluid pressure (oil temperature 50-60 °C {122-140 °F})

  9.31-9.80 MPa {95.0-99.9 kgf/cm2, 1360-1420 psi}

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

10. Turn the steering wheel fully to the left and right, then measure the fluid pressure generated at the gear housing.

  Caution

  • Do not maintain the steering wheel fully turned for 5 s or more. It is possible that oil temperature can rise, and this will negatively affect the oil pump.

  Note

  • If the fluid pressure is less than the specification, it is possible that the oil pump or gear housing is not operating correctly. Replace the oil pump as a single unit.

Gear housing fluid pressure (oil temperature 50-60 °C {122-140 °F})

  9.31-9.80 MPa {95.0-99.9 kgf/cm2, 1360-1420 psi}

11. After removing the SSTs, tighten the oil pump side joint of pressure hose to the specified torque.

Tightening torque

  29.4-44.1 N·m {3.00-4.49 kgf·m, 21.6-32.5 ft·lbf}

12. Bleed the air from the system.
