The power steering fluid reservoir is located in the engine compartment. It is on the passenger's side of vehicles with the L6 engine and is on the driver's side of vehicles with the V8 engine. See Engine Compartment Overview for reservoir location.
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.
Turn the key off, let the engine compartment cool down, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick.
For vehicles with the L6 engine, the level should be at the C (cold) mark. For vehicles with the V8 engine, the level should be at the FULL mark. If necessary, add only enough fluid to bring the level up to the mark.
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.
