radiator

any object that radiates energy

a device that cools the engine by transferring heat from the coolant to the air

A radiator is a part of a vehicle's cooling system that helps prevent the engine from overheating. It works by transferring heat away from the engine and into the air. The radiator is filled with coolant, which absorbs the heat produced by the engine. This coolant then flows through the radiator's metal parts, where it releases the heat and cools down. As the coolant circulates back into the engine, it helps maintain a safe operating temperature. Radiators are typically located at the front of the vehicle and are essential for keeping the engine running smoothly.
