Power Steering Fluid When to Check Power Steering Fluid The power steering fluid reservoir is located toward the front of the engine compartment on the driver's side of the vehicle. See Engine Compartment Overview on page 5-14 for reservoir location. 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. How to Check Power Steering Fluid Turn the key off and let the engine compartment cool down. The level should be between the MIN (B) and MAX (A) marks on the reservoir. If the level drops below the MIN (B) mark, add the power steering fluid. What to Use To determine what kind of fluid to use, see Part D: Recommended Fluids and Lubricants on page 6-26. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals. 5-34
