Power Steering Fluid: Testing and Inspection
POWER STEERING FLUID INSPECTION
Fluid Level Inspection
1. Verify that the fluid level is between MAX and MIN of the reserve tank when the engine is cold. If the fluid is not at the specified level, adjust the
fluid level (MIN-MAX on reserve tank) by adding/draining the fluid.
Fluid specification ATF M-III or equivalent (e.g. Dexron III)
Fluid Leakage Inspection
1. Start the engine and idle it.
2. Turn the steering wheel fully to left or right, to generate the fluid pressure.
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. Disconnect the oil pump side joint of the pressure hose, connect the SSTs set in the Step 1.
Tightening torque 29.4 - 44.1 Nm (3.00 - 4.49 kgf-m, 21.6 - 32.5 ft. lbs.)
3. Bleed the air from the system.
4. Open the gauge valve fully.
5. Start the engine, turn the steering wheel to the left and right to raise the power steering fluid to the appropriate temperature (50 - 60°C (122 - 140°
F)).
