A scooter engine cooling fan is a cooling component that is used to cool a scooter engine. Its function is to draw air through the radiator and over the engine, removing heat from the engine and helping to maintain the correct operating temperature. Some scooters have an automatic fan system, while others have a manual switch that the rider can use to turn the fan on and off as needed. A functioning engine fan is important for the overall health of a scooter's engine and helps prevent overheating, which can cause serious engine damage.
