Description: 100% Brand new and never been used. This Aluminum Radiator is designed to provide maximum cooling efficiency to prevent premature engine failure. Its light-weight, and high-heat transferring aluminum features a tube and fin design that, dramatically increases surface area that enables the heat to dissipate more efficiently. This Aluminum Radiator is at least 35%-45% more efficient than stock ones. Most importantly, it has a much higher capacity for coolant than stock ones, which means that your cooling system will be more efficient and will be more resistant to temperature surges in racing applications. Professional Installation is Highly Recommended No Instruction Included RADIATOR: Material: Full Aluminum Core Dimensions: 16 7/8" H x 26-1/4" W x 2" Overall Dimensions: 18-1/4" H x 31-5/8" W Upper Inlet 1-1/2" located on the Driver side Lower Outlet 1-1/2" located on the Passenger side Trans Cooler Included -1/2" 20 STRAIGHT THREAD G1/4- Mount Type: Saddle FANS: Maximum Fan CFM: 1730 cfm Fan Diameter (in): 12.050” Thickness (in): 2.500” Number of Blades: 10 blades Maximum Fan RPM: 2,250 rpm Blade Material: Plastic Amp Draw: 12.70 amps Includes the Mounting Tabs for an Easy Zip Tie Installation SHROUD AND FANS: The fan and the fan shroud effectively drive the heat over and out the engine compartment rather than thrusting it into the front of the engine. The fan shroud basically houses the fan blades securing it in place and keeping it from damaging the other engine components that may disturb the smooth and even operation of the engine. With excellent operating temperature management, allowable levels of engine temperature are stabilized. Investing in proper maintenance though will considerably benefit the ride and driving quality in maintaining the ideal working conditions of the engine.
