        No more yellow plastic!

        Great stock replacement. My old radiator was clogged causing my Mustang to overheat. Decided I might as well get a new overflow tank at the same time. Under hood looks clean now.

        Great OEM Replacement

        My original overflow tank had a crack in it after 14 years of use. I ordered this one from AM. It was a direct fit, completely identical to what came off of my GT.
