Power Steering Fluid
See Engine Compartment
Overview on page 5-12 for
reservoir location.
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.
For vehicles with the 4.2L L6 engine, the level should
be at the C (Cold) mark. For vehicles with the 5.3L V8
engine, the level should be at the FULL mark.
If necessary, add only enough fluid to bring the
level up to the mark.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricants on page 6-12.
Always use the proper fluid.
Notice: Use of the incorrect fluid may damage your
vehicle and the damages may not be covered by
your warranty. Always use the correct fluid listed in
Recommended Fluids and Lubricants on page 6-12.
