Radiator: 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 40% 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 Fan(s): 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 fan 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. Also, These Slim Fans have an 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.Package Included: 1 x Aluminum Radiator 2 x Slim Radiator Fan 2 x Fan Mount KitThis product is compatible with:96-03 GMC Sonoma96-03 GMC Jimmy96-03 Chevrolet S1097-05 Chevrolet BlazerFits Models with 4.3L V6 Engines ONLY
