Dewitts 1139003A 1968-72 Chevelle SB/BB Direct Fit Radiator, Automatic
(Part #1331139003A)
                        

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. In most cases, DeWitts double row radiators provide a 30% increase in heat rejection. Adding an electric fan will boost that number an additional 10%. If you're still not sure if that's enough, HP models are available with 1 1/4" tubes and offer approximately another 10% cooling capacity. Every DeWitts Aluminum radiator is designed to fit the listed application without any modifications to your car and is available in your choice of a natural, Black Ice or polished finish.

  • Direct fit with no modification
  • Epoxy free, aluminum, dual row core
  • 1" tubes
  • Press formed end tanks
  • 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.
