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 for the 3.5L V6 engine should be at the H (Hot) mark, and the level for the 3.6L V6 engine should be at the MAX (Maximum) mark. When it is cold, the level for the 3.5L V6 engine should be at the C (Cold) mark, and the level for the 3.6L V6 engine should be at the MIN (Minimum) mark. If the fluid is at the ADD mark on the 3.5L V6 engine, you should add fluid. If the level falls below the MIN mark on the 3.6L V6 engine, 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.
