Radiator Notes:   Corvette radiators were manufactured by the Harrison Division of General Motors at Lockport, New York. The early (1953-61) copper radiators have a Harrison Division identification tag soldered to the center, inlet side of the upper core tank, containing the radiator part number (as listed above) and a manufacturing date code. 1960-62 aluminum radiators have their part number and date code identification stamped into a tag which is fastened with screws to the top of the radiator.

Radiator Date Codes:

All radiator codes began with a two-digit set of charaters that consist of the model year. Example: a 1958 Corvette would have a "58" prefix to the date code. Following the modl year prefix is a monthly code which is shown below:
