What are the benefits of EMPs electric fan over belt-driven fans?
The fan is responsible for most, or all, of the airflow through the radiator when vehicles are operating at low or stationary speeds. The belt-driven fan slows down with the engine RPM, thus decreasing airflow to the radiator. It also takes horsepower from the engine to rotate, resulting in decreased engine performance, possible overheating and lower gas mileage. In contrast, electric fans maintain their speed regardless of engine RPM, providing constant, maximized airflow. The result is more effective cooling than with a belt-driven fan. Converting to an electric fan or adding an auxiliary electric fan eliminates engine horsepower drain, resulting in better engine performance and improved gas mileage.
