This Aluminum Core Radiator is designed to provide maximum cooling efficiency to prevent premature engine failure. Its lightweight, and high-heat transferring aluminum features a tube and fin design that, dramatically increases surface area that enables the heat to dissipate more efficiently.Radiators are essential in keeping your engine cool and removing excess heat that accumulates when the engine burns fuel. A failing radiator can lead to engine and transmission failure caused by overheating. Our radiators are 100% leak tested to prevent coolant loss and keep your engine running efficiently.
