The 15 Inch Flex-A-Lite Dual Electric Fan is a cooling fan designed for the demands of 2000-2004 Chevrolet and GMC trucks, as well as Suburban, Tahoe, Avalanche, Cadillac Escalade and Cadillac EXT with 34-inch wide radiator cores. Unlike other cooling car accessories, this powerful automotive fan moves 5500 cfm (cubic feet per minute) of airflow, allowing you to recover up to 17 horsepower and 20 pounds per foot of torque when used as a replacement for your stock clutch fan assembly. With overall dimensions of 17 x 31-7/8 x 4-1/2 inches, this radiator fan draws 28 amps from a 12-volt power supply and is built in the USA with globally sourced materials. This engine fan features two 15-inch straight blade fans and a direct fit design that bolts to O.E. mounting points of compatible models with 34-inch radiator cores. It includes a Flex-A-Lite Variable Speed Controller that varies the fan speed from 60 to 100 percent depending on radiator temperature to remove excess heat. The Flex-A-Lite Dual Electric Fan offers an effective solution to engine overheating, improving cooling performance and fuel economy.
