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 30%-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. Radiator Size: Material：full aluminum ROW：4 Row Core Size: 20 3/4 H x 19 1/4 W Overall Size: 26 3/4 H x 23 W Inlet Hose Connection: 1 1/2 Center Outlet Hose Connection: 1 3/4 Passenger Side OEM Style Brass Petcoke Drain CNC machined filler neck and cap Aircraft 5057 grade aluminum and with raw aluminum finish 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.
