71-73 Mustang Radiator AT 26in

The 71-73 Mustang Radiator AT 26in from Cold Case Radiators is a modern cooling solution engineered for first-generation Mustang owners who demand reliable heat dissipation during performance driving or daily operation. This aluminum radiator addresses the cooling limitations of factory equipment, particularly for vehicles running automatic transmissions that generate higher thermal loads under sustained driving conditions. Whether you're restoring a classic Mustang to show quality or building a restomod with contemporary engine modifications, this radiator ensures your cooling system won't become a bottleneck to reliability.

Cold Case Radiators engineered this unit with aluminum construction and optimized core design to maximize cooling capacity in the original 26-inch height envelope. The automatic transmission oil cooler integration allows seamless compatibility with AT-equipped Mustangs, eliminating the need for auxiliary cooling lines and simplifying installation. The compact 24-inch width and 7-inch depth fit within factory mounting points, preserving originality while delivering superior thermal performance compared to aging cast-iron factory cores. At 23 pounds, the aluminum construction reduces underhood weight while improving heat transfer efficiency—a meaningful upgrade for vehicles that see regular driving rather than static display.

Mustang enthusiasts restoring 1971–1973 models with automatic transmissions will find this radiator essential for preventing coolant boilover during summer driving or when swapping in higher-output engines. Installation requires no modifications to core support or mounting brackets, making it the direct-fit choice for both stock and lightly modified applications. Mechanics and restoration shops frequently specify Cold Case radiators for reliability and warranty support, making this a trusted component for long-term ownership.
