Radiator Chevelle 68-72 Auto Trans Raw

The Radiator Chevelle 68-72 Auto Trans Raw from DeWitts Radiator is a purpose-built cooling solution engineered for first-generation Chevelle owners running automatic transmissions. Whether you're restoring a muscle car to original specifications or upgrading cooling capacity for street or strip duty, this raw aluminum radiator addresses the thermal demands of classic Chevy performance. Built by DeWitts—a leader in custom radiator design for hot rodders and restoration enthusiasts—this unit delivers the reliable heat rejection that keeps your small-block or big-block engine operating within safe parameters during sustained driving.

This radiator features raw aluminum construction, which provides superior thermal conductivity compared to traditional copper-brass cores while remaining lightweight at 24 pounds. The raw finish allows builders to customize appearance through powder coating or polishing to match their specific build aesthetic. The core dimensions (24 x 8.75 x 42.75 inches) are precisely engineered to fit the factory mounting points of 1968–1972 Chevelle models equipped with automatic transmissions, ensuring bolt-in compatibility without modification. The aluminum construction also resists corrosion better than older designs and requires only standard coolant maintenance, making it both performance-oriented and practical for long-term ownership.

This radiator is ideal for Chevelle builders who prioritize authentic fitment without sacrificing cooling efficiency. Installation is straightforward for anyone with basic mechanical experience—the radiator drops into the factory location using stock mounting brackets, and it accommodates the automatic transmission cooler lines integral to your driveline setup. Technicians and restorers recommend this unit for street cars, weekend cruisers, and moderate performance builds where maintaining correct operating temperature directly impacts engine reliability and longevity. It pairs seamlessly with factory or aftermarket water pumps and is compatible with both mechanical and electric fan configurations.
