Chevrolet Silverado: Vehicle Checks / Power Steering Fluid

The power steering fluid reservoir is in the engine compartment on the driver
side of the vehicle. See Engine Compartment Overview for reservoir location.
When to Check Power Steering Fluid
It is not necessary to regularly check power steering fluid unless there is a
leak 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:
- Set the ignition off and let the engine compartment cool down.
- Wipe the cap and the top of the reservoir clean.
- Unscrew the cap and wipe the dipstick with a clean rag.
- Replace the cap and completely tighten it.
- Remove the cap again and look at the fluid level on the dipstick.
The level should be between the ADD and FULL marks. If necessary, add only enough
fluid to bring the level up to the hashed area between the ADD and FULL marks.
To prevent contamination of brake fluid, never check or fill the power steering
reservoir with the brake master cylinder cover off.
What to Use
Caution
Use of the incorrect fluid may damage the vehicle and the damages may not
be covered by the vehicle warranty. Always use the correct fluid listed in Recommended
Fluids and Lubricants.
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.
If the vehicle has the Duramax diesel engine, see the Duramax diesel supplement.
