Cold Case 70-81 Firebird Aluminum Radiator, (AT) CCR-GPF18A

1970–1981 Pontiac Firebird and Trans Am (GM F-Body) aluminum performance radiator for cars with an automatic transmission.

A direct-fit cooling upgrade with a built-in transmission cooler for second-generation Firebird and Trans Am automatics.

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
