70-72 A/B Body SB Radiat or & 16in Fan Kit AT

The 70-72 A/B Body SB Radiator & 16in Fan Kit AT from Cold Case Radiators is engineered for classic Mopar enthusiasts restoring or modifying 1970–1972 A-body and B-body platforms with small-block engines and automatic transmissions. This complete cooling solution addresses the thermal management challenges inherent to vintage muscle cars, where factory radiators often fall short under modified power outputs or modern driving conditions. Whether you're upgrading a stock 340, 360, or 383 small-block or installing a more aggressive engine combination, this radiator and fan assembly delivers the capacity and airflow needed to keep coolant temperatures in the safe zone during street driving, highway cruising, or spirited weekend runs.

Cold Case's radiator core uses modern all-aluminum construction with efficient tube-and-fin design, significantly improving heat rejection compared to original copper-brass units while reducing weight and eliminating corrosion issues common in older cores. The included 16-inch electric fan moves substantial CFM through the core, ensuring consistent cooling response regardless of engine speed or idle conditions—a critical advantage over mechanical fans that offer limited low-RPM effectiveness. The fan is calibrated for automatic transmission vehicles, where torque converter lock-up behavior and transmission cooling demand require precise thermal control. Mounting provisions are tailored to fit 1970–1972 A/B body engine bays without modification, and the assembly includes all necessary brackets, hose fittings, and wiring harness components for straightforward installation.

Restorers and street-machine builders benefit most from this kit, as the bolt-in design eliminates fabrication delays and the electric fan frees up parasitic engine horsepower compared to belt-driven mechanical alternatives. At 35.8 pounds and 27 inches wide, the radiator fits within factory dimensions and hood clearance parameters for unmodified or mildly customized A/B body frames. Compatibility is confirmed for Dodge and Plymouth models including the Duster, Valiant, Barracuda, Satellite, and Road Runner equipped with small-block engines and TorqueFlite automatics. Cold Case's reputation for precision fit and reliable thermal performance makes this kit the go-to choice for anyone serious about keeping vintage Mopar cooling systems modern and dependable.
