The power steering fluid reservoir is located in the engine compartment next to the engine coolant recovery tank. In the 3800 V6 (Code K) engine and the 3800 V6 Supercharged (Code I) engine, the power steering fluid reservoir sits low in the engine compartment. See Engine Compartment Overview .

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 for reservoir location.

How to Check Power Steering Fluid

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.

The level should be at the C (3100 V6 engine) or COLD (3800 V6 and 3800 V6 Supercharged engines) mark. If necessary, add only enough fluid to bring the level up to the mark.

When the engine compartment is hot, the level should be at the H (3100 V6 engine) or HOT (3800 V6 and 3800 V6 Supercharged engines) mark. If the fluid is at the ADD mark, you should add fluid.

What to Use

To determine what kind of fluid to use, see Part D: Recommended Fluids and Lubricants . Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.
