What is the difference between radiator fan and engine fan?

Both fans serve the critical function of cooling the engine and preventing it from overheating. The radiator fan, as the name suggests, is specifically responsible for cooling the radiator. It helps dissipate heat from the coolant that flows through the radiator, thus preventing the engine from overheating. The radiator fan is typically electrically powered and is controlled by the vehicle's engine control unit (ECU) based on the coolant temperature.On the other hand, the engine fan can refer to the same component but is often used in a broader sense to encompass the entire cooling system of the engine, including the radiator fan. It may also refer to other components such as the fan clutch, which is a mechanical component that regulates the speed of the fan depending on the engine's temperature.
