Correct answer
Cool the coolant arriving from the engine by transferring its heat to the air.
The radiator transfers to the air the heat that the coolant has absorbed from the engine. This cools the liquid before it circulates through the engine again. It is part of normal temperature regulation, rather than a device that operates only when the engine overheats.
