By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower than the Maximum mark, add more of the proper mixture to the coolant surge tank until the level reaches the mark. 5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. See your dealer, if necessary. 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 276 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. 297
