Power Steering Fluid The power steering fluid reservoir is located toward the rear of the engine compartment on the passenger's side of the vehicle. See Engine Compartment Overview on page 308 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. Remove the cap again and look at the fluid level on the dipstick. The fluid level should be somewhere within the cross-hatched area on the dipstick. If the fluid is at the ADD mark, you should add fluid. 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. What to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 420. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. 335
