Since 1984 every Howe radiator has started with a U.S. made aluminum core. The epoxy free 100% tube to fin contact in the Howe core provides for maximum heat transfer and dissipation. The Howe radiator is typically more than 7% cooler than a flux bonded aluminum core and more than 15% cooler than copper and brass. Howe radiators feature cast or billet filler necks and uniform height core flanges. They also feature crimped and welded tanks that are fitted to the core headers allowing the tanks to fit existing chassis mounts. Howe radiators are 100% TIG welded by hand by experienced craftsmen for exceptional quality and appearance. Each radiator is pressure tested and guaranteed against manufacturing defects.
