See if the engine cooling fan speed increases when idle speed is doubled by pushing the accelerator pedal down. If it does not, the vehicle needs service. Turn off the engine. Notice: Running the engine without coolant may cause damage or a fire. Vehicle damage would not be covered by the warranty. 10-21 If Steam is Coming from the Engine Compartment { WARNING Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when the engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop the engine if it overheats, and get out of the vehicle until the engine is cool. Engine Overheating If the vehicle has a diesel engine, see the Duramax diesel supplement. The vehicle has an indicator to warn of engine overheating. There is an engine coolant temperature gauge on the vehicle's instrument cluster. See Engine Coolant Temperature Gauge on page 5‑12. If the decision is made not to lift the hood when this warning appears, but instead get service help right away, see Roadside Assistance
