Repeat this procedure until the level remains constant at the FULL COLD mark for at least five minutes. 4. With the coolant surge tank pressure cap off, start the engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine cooling fans. By this time, the coolant level inside the coolant surge tank might be lower. If the level is lower than the FULL COLD mark, add more of the proper mixture to the coolant surge tank until the level reaches the FULL COLD mark. 5. Then replace the pressure cap. Be sure the pressure cap is hand-tight and fully seated. Power Steering Fluid See Engine Compartment Overview on page 5-14 for reservoir location. When to Check Power Steering Fluid Power steering fluid is used in all vehicles with V6 engines. Vehicles with the 4-cylinder engine have electric power steering and do not use power steering fluid. It is not necessary to regularly check power steering fluid unless a leak is suspected in the system, or an unusual noise is heard. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. 5-36
