Details

This radiator was used on 1969-72 small block Corvettes equipped with factory installed options. These options could include an automatic transmissions, air conditioning, or special engine options such as LT1 and L46. This “Direct Fit®” aluminum radiator features factory type press formed end tanks, dual row core, serpentine fins, and the factory type upper and lower channels. This radiator will provide 30% more cooling than the stock copper unit with half the weight and is epoxy free. It will fit into the stock core support and uses the original factory hoses. Absolutely no modifications are required. With the Black Ice™ finish this radiator looks and fits like the original radiator.

  • Direct Fit® with no modification
  • Epoxy free, aluminum, dual row core, 1" tubes
  • Press formed end tanks
  • Black Ice™ semi-gloss finish
  • Manual transmission radiator
  • Assembled and brazed in Howell, MI

Black Ice™ is a special two part epoxy paint. It is applied in a spray and it adheres to the aluminum and will never flake or peel off. The semi-gloss finish gives any radiator the look of an original copper/brass unit. The total thickness of the dried product is only .005” thick and it will not affect cooling performance.

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.
