When it is safe to lift the hood:

A. Engine Cooling Fan (Out of View)
B. Engine Coolant Surge Tank and Pressure Cap

If the coolant inside the coolant surge tank is boiling, do not do anything else until it cools down.

The vehicle should be parked on a level surface.

The coolant level should be between the MIN and MAX lines.

If it is not, the vehicle may have a leak at the radiator hoses, heater hoses, radiator, water pump, or somewhere else in the cooling system.

If there seems to be no leak, with the engine on, check to see if the electric engine cooling fan is running. If the engine is overheating, the fan should be running. If it is not, the vehicle needs service. Turn off the engine.

Notice: Using coolant other than DEX-COOL® can cause premature engine, heater core, or radiator corrosion. In addition, the engine coolant could require changing sooner, at 50 000 km (30,000 mi) or 24 months, whichever occurs first. Any repairs would not be covered by the vehicle warranty.
Always use DEX-COOL (silicate-free) coolant in the vehicle.
