With more air going in and more fuel meeting the air, a really big bang happens. That big bang means the creation of heat. Heat robs power, can wear down your engine prematurely, and can quickly melt surrounding parts. To keep the LSX376 running nice and cool, we upgraded the puny factory radiator with a handbuilt, aluminum, Direct-Fit unit from Be Cool. Engineered to mount in place of the factory radiator, the Be Cool radiator has better cooling power, is up to 40 percent lighter, and guaranteed to lower your coolant temperature a minimum of 20 degrees. Now that is impressive. Combine the Be Cool aluminum radiator with Be Cool's own coolant and antifreeze, and there is no doubt our project truck will running nice and cool. A cooler engine means more power.
