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 on page 5-12 for reservoir location. What Power Steering Fluid to Use To determine what kind of fluid to use, see Recommended Fluids and Lubricants on page 6-12. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. Windshield Washer Fluid What Washer Fluid to Use When you need windshield washer fluid, be sure to read the manufacturer's instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. See Engine Compartment Overview on page 5-12 for reservoir location. How to Check Power Steering Fluid To check the power steering fluid, do the following: 1. Turn the engine off and let the engine compartment cool down. 2. Wipe the cap and the top of the reservoir clean, and then unscrew the cap. 3. Wipe the dipstick with a clean rag, then remove the cap again and look at the fluid level on the dipstick. 4. Replace the cap and completely tighten it. When the engine compartment is hot, the level should be at the H (hot) mark. When it is cold, the level should be at the C (cold) mark. If the fluid is at the ADD mark, you should add fluid. 5-36
