The aluminum radiator used on 1961 and 1962 Corvettes uses only one GM part number, yet several changes were made during this two-year period. 1961 radiators were not painted until the middle of production. Late 61 & all 62 radiators were all painted black gloss enamel. There was yet one more major change to the radiator in March of 1962. The part number and date code stamped into the top of the radiator. The aluminum tag was changed to be a "stick on" coolant. These date stamped 1962 radiators were the only coolant system parts that ever used the "month/year" format instead of "year/month" that was used on all other years, including expansion tanks. The first stamped radiator was "C62". Service parts produced after 1963 used the formed metal tank and tube assembly from the C2’s instead of the upper castings.
