Cold Case 61-64 Pontiac Full Size Aluminum Radiator, AC, (AT) CCR-GMP20A

1961–1964 Pontiac full-size (Bonneville, Catalina and Grand Prix) V8 389/421 aluminum performance radiator for cars equipped with factory air conditioning, automatic transmission.

A direct-fit aluminum upgrade for big-car Pontiacs that keeps the 389 and 421 running cool while retaining the factory appearance.

Cold Case builds this radiator from 100% TIG-welded aluminum with two oversized cooling rows for high coolant volume. It runs cooler than a stock copper/brass radiator—a Cold Case 2-row typically outperforms an original 4-row core by roughly 10–15%—while weighing far less. It is engineered as a direct-fit replacement with the correct factory stamping and OE-style fittings, so once painted it is nearly indistinguishable from an original.

Features & specs:

• 100% TIG-welded all-aluminum construction
• Two oversized cooling rows with 1.25" tubes for high coolant volume
• 16 fins per inch with corrugated fins for maximum surface area and heat transfer
