At low RPM, when the engine needs cooling the most, a flex fan blows sufficient air over the radiator. However, as the RPM increases and the vehicle goes faster, the fan speed increases as well, robbing valuable power and mileage. The blades of the flex fan actually flatten out completely at a certain RPM, and therefore encounter almost no resistance. Once the engine slows down, the blades return to their natural shape and move air again. As a result, power is freed up for your vehicle, mileage is increased, and the fan is not unnecessarily blowing air over the radiator that is getting enough air coming through the grille. If you are looking for quality swirl-flex fan blades, Hayden has you covered. This product is designed to be used without a fan clutch. The blades flatten out completely at high RPM to reduce drag on the engine. The part is manufactured from stainless steel to ensure long service life.
