When to Check Power Steering Fluid

It is not necessary to regularly check power steering fluid unless a leak is suspected in the system, or an unusual noise is heard. 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

If your vehicle has the 3.5L V6 engine, the fluid level should be between the ADD and HOT marks when the engine is cold, and at the HOT mark when the engine is hot. If the fluid is at the ADD mark when the engine is cold or hot, power steering fluid should be added.

If your vehicle has the 3.6L V6 engine, the fluid level should be between the MIN (Minimum) and MAX (Maximum) marks when the engine is cold. and at the MAX mark when the engine is hot. If the fluid is at the MIN mark when the engine is cold or hot, power steering fluid should be added.

The fluid level should be within the crosshatch area on the dipstick.

If the fluid is at or below the ADD mark on the dipstick, add just enough fluid to bring the level within the crosshatch area.
