Radiator Chevelle 66-67 Auto Trans Raw

The Radiator Chevelle 66-67 Auto Trans Raw from DeWitts Radiator is purpose-built for first-generation Chevelle owners running automatic transmissions who demand factory-correct cooling performance without compromise. This aluminum core radiator addresses the thermal demands of mid-60s Chevrolet muscle cars, where adequate heat dissipation is critical for reliability during street driving, weekend cruises, or spirited acceleration. Whether you're restoring an original SS or maintaining a well-sorted restomod, proper cooling ensures consistent engine temperatures and extends powertrain longevity.

This raw aluminum construction delivers superior thermal conductivity compared to older copper-brass radiators, allowing faster heat rejection while maintaining a lighter overall weight of just 22 pounds. The core design is specifically calibrated for automatic transmission coolant return flow patterns, preventing hot spots and vapor lock that plagued original equipment. DeWitts engineers optimize fin density and tube layout to maximize surface area contact with engine coolant, ensuring efficient heat transfer even under load. The raw finish allows you to customize appearance with polishing, powder coating, or protective paint to match your restoration vision.

Chevelle restorationists, street machine builders, and vintage Chevy enthusiasts benefit immediately from this radiator's plug-and-play fitment for 1966–67 models equipped with Turbo 400 or Powerglide automatics. Installation is straightforward—it mounts into the factory radiator support without modification, preserving originality while upgrading cooling capacity. The compact 27.5 x 8.5 x 32.5 inch envelope fits within stock dimensions, ensuring compatibility with original fan shrouds and hose routing. This is an essential upgrade for any builder serious about reliability, whether cruising to local cars and coffee or tackling summer highway miles.
