Power Steering Fluid The power steering fluid reservoir is located in the engine compartment on the driver's side of the vehicle. See Engine Compartment Overview on page 5-14 for reservoir location. How to Check Power Steering Fluid To check the power steering fluid, do the following: 1. Turn the key off and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean. 3. Unscrew the cap and wipe the dipstick with a clean rag. 4. Replace the cap and completely tighten it. 5. Then remove the cap again and look at the fluid level on the dipstick. The level should be at the COLD FILL mark. If necessary, add only enough fluid to bring the level up to the mark. 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. To prevent contamination of brake fluid, never check or fill the power steering reservoir with the brake master cylinder cover off. What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 6-15. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. 5-35
