10-20 Vehicle Care 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 COLD FILL line. 5. 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 5‑11. The decision may be made not to lift the hood when this warning appears, but instead get service help right away. See Roadside Assistance Program on page 13‑6. If the decision to lift the hood is made, make sure the vehicle is parked on a level surface. Then check to see if the engine cooling fan(s) are running. If the engine is overheating, the fan(s) 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. 3. Fill the coolant surge tank with the proper DEX-COOL coolant mixture, to the COLD FILL line. 4. With the coolant surge tank pressure cap off, start the engine and let it run until the upper radiator hose can be felt getting hot. Watch out for the engine cooling fan. 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.
