66-68 Impala Radiator Dual 12in Fans

The 66-68 Impala Radiator Dual 12in Fans from Cold Case Radiators is purpose-built for classic muscle car enthusiasts and restoration specialists who demand reliable cooling performance in vintage full-size Chevrolets. This radiator addresses the cooling challenges inherent to first-generation Impalas, particularly when upgrading to modern engine builds or simply maintaining consistent temperatures during cruising and highway driving. Whether you're restoring an original 283, rebuilding with a 327, or going all-in with a big-block conversion, this dual-fan setup provides the thermal capacity and modern engineering that classic cooling systems simply cannot deliver.

Cold Case Radiators engineers these units with aluminum construction and efficient core design to maximize heat rejection while fitting within the original engine bay footprint. The dual 12-inch electric fan configuration operates independently or in tandem, allowing intelligent thermal management without the weight and complexity of a traditional belt-driven fan clutch. This dual-fan approach also eliminates parasitic horsepower loss from mechanical drive systems, meaning more power stays at the wheels. The 48-pound assembly integrates seamlessly with period-correct hose connections while providing substantially greater cooling capacity than stock copper-brass radiators, critical when running modern ignition systems, air conditioning, or performance modifications that generate additional engine heat.

This radiator is ideal for 1966, 1967, and 1968 Chevrolet Impala builds ranging from stock restorations to serious street machines and light track use. Owners upgrading from original cooling systems will see dramatically improved temperature stability, particularly in stop-and-go traffic or when towing. Installation requires basic mechanical aptitude and standard cooling system plumbing; the dual-fan electrical system can integrate with existing wiring harnesses or be wired to a standalone thermostat controller for maximum flexibility. Dimensions of 16 x 26 x 36 inches ensure tight engine bay fitment typical of mid-60s Chevrolets, so verify clearance with your specific frame and engine combination before ordering.
