Power Steering Fluid: Testing and Inspection
INSPECTION
1. Check power steering fluid for deterioration or contamination. If the fluid is highly deteriorated or contaminated, drain it and refill with new fluid.
2. Check joints and units for oil leakage. If any oil leaks are found, repair or replace the applicable part.
3. Inspect fluid level on flat and level surface with engine "OFF" by indicator of reservoir tank.
If the level is at lower point or below, add fluid to keep the level in the specified range of the indicator. If at upper point or above, drain fluid by using a syringe or the like.
a. Check at temperature 20°C (68°F) on reservoir surface of oil pump; read the fluid level on the "COLD" side.
b. Check at temperature 80°C (176°F) on reservoir surface of oil pump; read the fluid level on the "HOT" side.
