What is Cooling Fan
a cooling fan is an essential component of a vehicle's cooling system. It is responsible for cooling the engine by drawing in air through the radiator and then expelling it out into the engine compartment. the cooling fan helps to regulate the temperature of the engine and stop it from overheating, which can cause serious damage to the engine and other components.
the cooling fan is controlled by the engine's control module, which monitors the engine's temperature and activates the fan as needed. in some vehicles, the cooling fan may also be controlled by a thermostatic switch that turns on the fan when the engine reaches a certain temperature.
Overall, the cooling fan plays a critical role in maintaining the proper operating temperature of the engine, ensuring optimal performance and stoping damage from overheating
