Power Steering Fluid: Testing and Inspection

CHECK FLUID LEVEL






a. Keep the vehicle level.
b. With the engine stopped, check the fluid level in the oil reservoir. If necessary, add fluid.
Fluid: ATF DEXRON(R) II or III

HINT: When hot, check that the fluid level is within the HOT LEVEL range on the reservoir.

If the fluid is cold, check that it is within the COLD LEVEL range.
c. Start the engine and run at idle.
d. Turn the steering wheel from lock to lock several times to raise fluid temperature.
Fluid temperature: 75 to 80°C (167 to 176°F)





e. Check for foaming or emulsification.
If foaming or emulsification is identified, bleed air in the power steering system (see Power Steering Bleeding).





f. With the engine idling, measure the fluid level in the reservoir.
g. Stop the engine.
h. Wait a few minutes and measure the fluid level in the reservoir again.
Maximum fluid level rise: 5 mm (0.20 inch) or less
If the fluid level rise exceeds the maximum, bleed air in the power steering system (see Power Steering Bleeding).
i. Check the fluid level.
