70-74 E Body Challenger Radiator AT 23.25x28.85

The 70-74 E Body Challenger Radiator AT 23.25x28.85 from Cold Case Radiators is purpose-built for 1970–1974 Dodge Challengers equipped with automatic transmissions, delivering reliable engine cooling for street, strip, and restored muscle cars. This radiator addresses the thermal demands of classic E-body platform vehicles, where factory cooling systems often fall short under modern driving conditions or performance modifications. Whether you're running original engine specifications or upgraded power, a quality radiator replacement is essential to prevent overheating, detonation, and long-term engine damage.

Cold Case Radiators engineered this unit with aluminum construction and optimized core design to maximize heat dissipation while maintaining OEM-style fitment and mounting points. The 23.25-inch width and 28.85-inch height match factory dimensions precisely, eliminating fabrication work and preserving engine bay aesthetics on original restorations. The automatic transmission cooler integral to this radiator ensures proper fluid temperature control—critical for transmission longevity, especially on vehicles seeing frequent driving or towing. Advanced tube-and-fin technology increases surface area for cooler temperatures compared to aging factory cores, while maintaining the correct pressure rating for E-body cooling systems.

Restoration enthusiasts, daily drivers, and performance enthusiasts benefit from the drop-in compatibility and proven durability of this radiator design. Installation requires standard hose and mounting hardware; no modifications to the engine bay or frame are necessary for 1970–1974 automatic-equipped Challengers. Pair this radiator with a quality thermostat, fresh coolant, and properly sized fan to optimize cooling efficiency. The 23.1-pound unit is manageable for most home mechanics, making radiator replacement a practical weekend project that yields immediate results in engine temperature stability and peace of mind on the road.
