55-56 Chevy Radiator 6 Cylinder Black

The Cold Case Radiators 55-56 Chevy Radiator 6 Cylinder Black is a modern aluminum cooling solution engineered specifically for first-generation Chevrolet full-size cars from the 1955–1957 model years. This Night Rider Series radiator combines authentic period appearance with contemporary thermal performance, delivering efficient heat rejection for six-cylinder Chevy engines while maintaining the factory aesthetic that classic car enthusiasts demand.

Measuring 23.5 inches wide by 23.5 inches tall with a 3-inch depth, this aluminum radiator is designed with a center inlet and passenger-side outlet configuration, matching the original cooling system architecture of early Chevy fullsize vehicles. The black paint finish integrates seamlessly with vintage restoration builds while the aluminum core provides superior heat transfer compared to older copper-brass designs. At 22 pounds, it's lighter than many original units, improving weight distribution without sacrificing cooling capacity—a consideration for drivers prioritizing handling balance alongside thermal management.

This radiator is ideal for restorers and hot rod builders tackling 1955–1957 Chevrolet full-size cars, particularly those equipped with inline six-cylinder engines. Whether undertaking a stock restoration or a mild performance build, the correct radiator sizing and inlet/outlet positioning are critical to avoiding air pockets and cooling system pressure loss. Cold Case Radiators manufactures to OEM dimensions for proper fitment, eliminating clearance issues and hose routing complications common when adapting non-original cooling cores.
