1960-1961 C1 Restoration Radiator

Model: 32-940A (GM# 3147516 – Oct. 1960 to Dec. 1960) The first aluminum radiator (GM# 3147516) was used in 1960 high-performance (270/290Hp) Corvettes. This radiator had an aluminum overflow tank attached to the top and is therefore commonly referred to as a Top-Tank Radiator. This tank was not a pressured expansion tank. The first version featured a smooth flat top and had no plastic coolant-level viewing plug. The radiator was unpainted and used a 13-psi pressure cap. Model: 32-940B (GM# 3147516 – Jan. 1960 to July. 1960) (GM# 3151116 – Aug. 1960 to Oct. 1961 vin# 1700) In the middle of the 1960 production year, five ribs were added to the top of the tank for added strength. Shortly after that change, the plastic coolant-level sight hole was added, creating yet a third version of the radiator. The radiator part number changed to 3151116 for the early 1961 (270/315) high-performance Corvettes and was used up to Vin. number 1700. The only change made to the radiator was an aluminum nipple, and coupling creating a drain plug extension (Sold separately). None of the original production versions were painted. Only GM service parts were painted black. Radiators with the sight hole will include the correct plastic plug with TY-16.
