Scott Drake designed this downflow aluminum radiator with an exclusive baffle at the top to help evenly distribute the flow of hot water across the upper part of the radiator. This aluminum radiator is 100% fully tig welded. The inlet and outlet on the radiator are located on the same side and also include a built-in petcock on the lower driver side of the radiator. This aluminum 2-row radiator features extra-large 1" tubes for 4-row efficiency, but with 5-7 lbs. less weight, while solving the original radiator's serious problem of distributing the hot water to the far-right side of the radiator. This aluminum radiator includes an automatic transmission cooler with 1/2"x20 inverted flare fittings.
