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" in the Index 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. 3100 V6 Engine 6-32
