High-Flow Aluminum LS Radiator for 1973-77 A-Body Manual Trans

Achieving consistent temperature control in your 1973 to 1977 A Body manual LS swap, the 100 percent TIG welded aluminum core and tanks deliver rapid heat rejection, corrosion resistance and durable lightweight performance. Expertly crafted in the USA to factory fitment standards, this radiator ensures straight fit installation, superior thermal efficiency and reliable operation that enhances driving confidence and resale value.

1973-1977 GM A-Body LS Radiator for Manual Transmission

Swapping an LS powerplant into a 1973 through 1977 A-Body Chevelle, Monte Carlo or El Camino with a manual gearbox calls for a cooling assembly that fits stock frame rails and hose paths precisely, a task this radiator is built to solve. Engineered with TIG welded aluminum core and tanks made in the USA, it resists corrosion and sheds heat quickly while maintaining original firewall clearances. Beyond simple fitment the inlet and outlet necks align with factory hoses to avoid trimming sheet metal, and its consistent thermal control under varied driving conditions safeguards valve seals and gaskets during both daily commutes and spirited runs.

Precision TIG Welding and Aluminum Durability

Every joint in this radiator is formed using TIG welding, a process that provides precise heat control to reduce porosity and create exceptionally strong seals between the tanks and the core. This method produces joints that withstand the intense vibration and heat cycles generated by modern LS engines, effectively minimizing the risk of leaks over time. The choice of high quality aluminum for both core and tanks further enhances the assembly's ability to resist corrosion from coolant and road moisture. Aluminum construction also guarantees consistent sealing performance under repeated pressure changes, which translates to reliable containment of coolant during spirited driving or heavy load conditions. Built in the USA to strict standards, this unit offers the kind of structural integrity required for demanding engine swap applications.

Optimized Heat Rejection and Chassis Balance

The radiator's all aluminum core features highly conductive passages that pull heat away from circulating coolant with remarkable speed, helping to prevent temperature spikes even under heavy throttle or stop and go traffic. Its low mass means less weight mounted ahead of the firewall, which preserves the original handling characteristics of the A Body platform and maintains steering responsiveness. Because aluminum naturally resists electrolysis and rust, internal flow passages remain clear for years, ensuring constant coolant flow rates and stable engine temperatures across a range of driving scenarios. This combination of rapid heat transfer and reduced front end weight supports confident performance whether you're cruising city streets or carving winding back roads. Consistent temperature control also helps protect head gaskets and valve seals, extending engine life.

Seamless Fitment for A Body Manual Transmission Swaps

Designed specifically for Chevelle, Monte Carlo and El Camino models from 1973 to 1977 with a manual gearbox, this radiator slides into the factory frame rails without any trimming or bracket fabrication. The inlet and outlet necks align precisely with stock hoses, preserving the original firewall clearance and avoiding interference with sheet metal or chassis components. By matching the factory hose paths and fan shroud mounts, the design prevents the common fitment issues often encountered with off the shelf cooling upgrades. Installation remains straightforward for professional mechanics and enthusiasts alike, reducing labor time and lowering the risk of costly modifications. The result is a clean engine bay, reliable cooling performance and a swap that stays true to the vehicle's styling and structure.

This radiator ensures reliable temperature control in daily street use and spirited drives. For the same radiator but with fans, see our 1973-1977 A-Body LS Radiator (Manual Transmission) with Fans.
