Power Steering Fluid: Testing and Inspection
Checking Power Steering Fluid Level
1. Position the vehicle on a level surface.
2. Start the engine. With the vehicle kept stationary, turn the steering wheel several times continuously to raise the fluid temperature from 50 - 60°C
(122 - 140°F).
3. With the engine at idle, turn the steering wheel fully clockwise and counterclockwise several times.
4. Make sure that there is no foaming or cloudiness in the reservoir fluid.
5. Stop the engine and check for any difference in fluid level between a stopped and a running engine.
NOTE:
1) If the fluid level varies 5 mm (0.2 inch) or more, bleed the system again.
2) If the fluid level suddenly rises after stopping the engine, it shows that bleeding is not satisfactory.
3) Incomplete bleeding will produce a chattering sound decreasing durability of the pump, etc.
