The superior quality of a DeWitts® radiator begins with a manufacturing process that is controlled 100% in house. Every core is assembled and brazed in Howell, MI to ensure excellence throughout the entire build. DeWitts® is the only USA aftermarket radiator company to own an aluminum Nocolok® brazing furnace which allows for production of a superior, epoxy free, aluminum core. DeWitts® radiators are assembled with press formed end tanks which eliminate fabrication seams and potential leak points of common box tanks while providing an original equipment look for your classic car.
