Power Steering Fluid When to Check Power Steering Fluid It is not necessary to regularly check power steeringfluid 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. How to Check Power Steering Fluid Turn the key off, let the engine compartment cool down, wipe the cap and top of the reservoir clean, then the unscrew the cap and wipe the dipstick with a clean rag. Replace the cap andcompletely tighten it. Then remove the cap again and lookat the fluid level on the dipstick. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark. The power steering fluid reservoir is located next to the underhood fuse block on the passenger's side of the vehicle. See Engine Compartment Overview on page 5-12 for more information on location. What to Use To determine what kind of fluid to use, see Part D: Recommended Fluids and Lubricants on page6-15. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. 5-36
