Just like other major components in the car, the radiator cannot work on its own. It has supporting parts that help it perform its function more efficiently. In order for the radiator to reduce temperature of the water and coolant mixture that goes through the engine, it needs airflow that absorbs the heat and assists evaporation. Radiator fans are used to draw the air towards the radiator and help in the cooling process. High performance radiator fans may be used to replace your OE product for more efficient cooling. They allow more air to circulate around the radiator and they need less horsepower to operate too, making them ideal for your radiator fan replacement. Radiator fans come with ultra slim design so the fan can be installed easily against your radiator, in the most convenient position to allow for more leniencies for other aftermarket parts. Maximum fan CFM: 1730 CFM fan diameter (in): 10.05 maximum fan RPM: 2250 RPM number of blades: 10 blades Thickness (in): 2.5 blade material: plastic amp draw: 12.70 amps
