The cooling system allows the engine to maintain the correct working temperature.

When it is safe to lift the hood:

A. Electric Engine Cooling Fan(s)

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

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.
