The cooling fan is a very important element in the engine cooling system of the vehicle. The combustion occurring within the propeller generates large amounts of heat, which effectively eliminates the radiator when the vehicle is in motion, since the cool ambient air achieved naturally pass through. When we stopped in traffic, or we move very slowly, the air flowing through the radiator is enough, and that is why the system has the radiator fan for cooling. In this article we will see how to change the radiator fan vehicle.
