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 3.8L V6 engine or the
5.3L V8 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.
What to Use
To determine what kind of fluid to use, see
Recommended Fluids and Lubricants on page 6-11.
Always use the proper fluid.
Notice: Use of the incorrect fluid may damage the
vehicle and the damages may not be covered by
the vehicle’s warranty. Always use the correct fluid
listed in Recommended Fluids and Lubricants
on page 6-11.
Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s instructions before use. If you will be
operating your vehicle in an area where the temperature
may fall below freezing, use a fluid that has sufficient
protection against freezing.
