When to Check Power Steering Fluid

It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

How to Check Power Steering Fluid

To check the power steering fluid, do the following:

  1. Turn the key off and let the engine compartment cool down.
  2. Wipe the cap and the top of the reservoir clean.
  3. Unscrew the cap and wipe the dipstick with a clean rag.
  4. Replace the cap and completely tighten it.
  5. Remove the cap again and look at the fluid level on the dipstick.

When the engine compartment is hot, the level should be at the H (hot) mark. When it is cold, the level should be at the C (cold) mark. If the fluid is at the ADD mark, you should add fluid.

What Power Steering Fluid to Use

To determine what kind of fluid to use, see Recommended Fluids and Lubricants . Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.
