10-18 Vehicle Care Check the level in the coolant surge tank when the cooling system has cooled down. If the coolant is not at the proper level, repeat Steps 1 through 3 and reinstall the pressure cap. If the coolant still is not at the proper level when the system cools down again, see your dealer. If the decision is made to lift the hood, make sure the vehicle is parked on a level surface. Then check to see if the engine cooling fans are running. If the engine is overheating, both fans should be running. If they are not, do not continue to run the engine and have the vehicle serviced. Notice: Engine damage from running the engine without coolant is not covered by the warranty. Notice: If the engine catches fire because of being driven with no coolant, the vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty. 3. Fill the coolant surge tank with the proper DEX-COOL coolant mixture to the indicated level mark. 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 fan. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper DEX-COOL® coolant mixture to the coolant surge tank until the level reaches the indicated level mark. 5. Then replace the pressure cap. Be sure the pressure cap is hand-tight. Engine Overheating The vehicle has an indicator to warn of engine overheating. There is an engine coolant temperature warning light on the vehicle's instrument panel. See Engine Coolant Temperature Gauge on page 5￿14. If the decision is made not to lift the hood when this warning appears, but instead get service help right away. See Roadside Service (U.S. and Canada) on page 13￿8 or Roadside Service (Mexico) on page 13￿10.
