This radiator has an aluminum overflow tank attached to the top and is therefore commonly referred to as a "Top Tank". This tank was not a pressure expansion tank. The radiator changed for the early 1961 270/315 High-Performance Corvettes and was used up to VIN number 1700. None of the original production versions were painted. Only GM service parts were painted black. We are now offering this radiator in any version you need. Please specify if you want the flat top, ribs, and/or sight hole. With a plastic plug with TY-16.
Based in Michigan, DeWitts Radiator is the only aftermarket radiator manufacturer in the US which owns an aluminum Nocolok blazing furnace. With a twelve-person crew, DeWitts builds custom and direct fit radiators for 1955-present Corvettes from start to finish at their Howell, MI plant. No epoxy is used in the making of their radiators, and their construction methods eliminate seams and possible leak points. Their Lifetime Warranty is industry leading, and Zip only recommends DeWitts Radiators to our customers.
