Radiator Extruded Tube 62-67 Nova/Chevy II

The Radiator Extruded Tube 62-67 Nova/Chevy II by PWR North America is the engineered cooling solution for Chevrolet Nova and Chevy II owners seeking improved thermal management and reliability. This heavy-duty radiator core is designed for classic car enthusiasts and restoration builders who demand authentic fitment and modern cooling performance from their first and second-generation Novas. Whether you're performing a frame-off restoration, upgrading a weekend cruiser, or building a street performance machine, this extruded tube radiator delivers the heat rejection capability your small-block Chevy needs during extended driving or spirited road conditions.

PWR's extruded tube design maximizes cooling surface area through precision-brazed aluminum construction, allowing coolant flow efficiency that rivals modern vehicles while maintaining period-correct dimensions for 1962–1967 Nova and Chevy II engine bays. The extruded core geometry features multiple tube passes that optimize heat transfer from hot coolant to ambient air, reducing cylinder head temperatures and preventing boil-over conditions under load. Aluminum construction provides superior weight savings compared to original copper-brass cores, and the robust design withstands higher pressures typical of modern water pump and thermostat combinations, making it compatible with both stock and upgraded cooling systems.

This radiator core is ideal for builders upgrading cooling capacity without sacrificing authenticity or frame clearance in factory engine compartments. Installation suits original mounting brackets and hose locations on 1962–1967 Nova and Chevy II platforms, making it a direct replacement option for tired or leaking original cores. The 34.73 lb weight and compact core dimensions (27" × 13" × 38") ensure proper fit within original radiator shrouds and support brackets, while the extruded tube construction provides the durability needed for high-temperature summer driving, towing, or performance applications where stock cooling falls short.
