Radiator for LS and LT Engine Swaps in 1968-1972 Chevy Nova & 1964-1966 Buick Skylark
When a modern LS or LT motor finds its way into a 1968 to 1972 Nova or a 1964 to 1966 Skylark fitted with a manual transmission the factory cooling system often cannot keep temperatures in check under load. This radiator uses precision TIG welded aluminum tanks and a multi tube core to channel heat away from the engine block quickly. Mounting pads are calibrated to fit the GM X Body frame so you can bolt it down with original brackets and skip any trimming or drilling. You have the choice of a polished aluminum finish or a black epoxy coat that resists corrosion through daily use.
Precision TIG Welding for Robust Aluminum Bodies
The radiator's tanks and core use TIG welding to fuse premium aluminum with high seam integrity. This process applies an electric arc to the joint under an inert gas shield for a smooth bond that reduces heat warping. The result is minimal distortion of the tank walls for a perfect shape that resists fatigue under constant vibration. Full fusion at each joint also ensures a leak resistant barrier that can handle the demands of modern LS and LT powerplants.
Optimized Multi Tube Core for Rapid Cooling
Featuring a multi tube core layout, this radiator maximizes coolant contact area to move heat away from the engine block swiftly. The increased internal passages promote efficient thermal exchange while maintaining coolant flow under high rpm conditions. Aluminum's inherent thermal conductivity allows each tube to shed heat quickly into the fin array, stabilizing temperatures even during spirited driving. Lightweight construction further aids in heat rejection by reducing radiant mass in the engine bay.
Exact Fitment on GM X Body Frames
All mounting pads are machined to match the 1968 through 1972 Chevy Nova and 1964 through 1966 Buick Skylark frame rails precisely. This direct bolt in design uses the factory brackets so you avoid any frame cutting or drilling during installation. Tight tolerances ensure the radiator sits square in the support frame for consistent airflow through the core. Each unit is made in America under strict quality control to guarantee uniform fit and finish across production runs.
Coating Choices that Resist Corrosion
Choose between a polished bare aluminum finish for classic show quality or a black epoxy coat for an extra layer of protection against road salts and moisture. The aluminum surface resists oxidation naturally but the epoxy coat adds abrasion resistance for daily driving conditions. Both options maintain their appearance and function through frequent engine heat cycles and exposure to environmental elements. This makes the radiator as reliable in winter months as it is in warm weather outings.
