The aluminum radiator used on 1961 and 1962 Corvettes uses only one General Motors part number, yet several changes were made during this two-year period. The most obvious difference is the upper cast neck used on 1961 models. This casting (part 3150896) included a raised square bump on the top of the casting. All 1962 models omitted this raised bump and the casting was flat but it retained the same casting number. Since this casting number is so obviously positioned, several people confuse thiswith the part number of the radiator. 1961 radiators were not painted until the middle of production. Late 1961Æs & all 1962 radiators were all painted black gloss enamel.
As a result of the different castings, we created our model 944 for1962 model Corvettes. This radiator features the flat upper casting and has an expansion joint cut into the top plate. According to several original samples and the GM blueprints this "saw cut" was not introduced until 6-25-1961, which means no 1961should have it.
