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. See Engine Compartment Overview
on page 5-12 for reservoir location.
How to Check Power Steering Fluid
To check the power steering fluid, do the following:
1. Turn the engine off and let the engine compartment
cool down.
2. Wipe the cap and the top of the reservoir clean,
and then unscrew the cap.
3. Wipe the dipstick with a clean rag, then remove the
cap again and look at the fluid level on the dipstick.
4. Replace the cap and completely tighten it.
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 on page 6-12.
Always use the proper fluid. Failure to use the proper
fluid can cause leaks and damage hoses and seals.
Windshield Washer Fluid
What Washer Fluid 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. See Engine
Compartment Overview on page 5-12 for reservoir
location.
