LS Swap Radiator for 1963-1972 Chevy Corvette Automatic Transmission
When adapting an LS powerplant to a 1963 to 1972 Chevy Corvette with automatic transmission the factory cooling system often falls short and this pin mount radiator is engineered to restore reliable temperature control. It drops into the original Y Body pin locations without custom brackets or cutting and maintains hood clearance while aligning with the stock fan shroud. Constructed from TIG welded aluminum tanks and core it delivers steady coolant flow and rapid heat dissipation under spirited driving. Builders can choose raw finish or epoxy coating for corrosion resistance and classic underhood style.
Precision TIG Welding for Unmatched Strength and Conductivity
The radiator features 100% TIG welded aluminum tanks and core that produce deep fusion along every joint. This method creates a bond at the molecular level, eliminating weak seams and allowing heat to pass swiftly from coolant to air. The uniform weld beads resist vibration and the cyclic pressure produced by an LS engine under load, reducing the risk of fatigue or leaks. Builders will appreciate the combination of structural integrity and steady thermal transfer that supports sustained spirited driving. Overall, precision TIG welding ensures both durability and consistent cooling performance.
Direct Fitment to 1963-1972 Corvette Y Body Chassis
Designed for the original pin mount positions, this radiator drops straight into a 1963-1972 Corvette frame without cutting or custom brackets. It maintains the correct hood clearance while aligning perfectly with the factory automatic transmission fan shroud. Installation time is slashed, as installers simply secure the unit using the stock hardware and mounting points. By preserving the chassis geometry, the system sustains proper airflow patterns that the Corvette was engineered for. The outcome is a seamless upgrade that feels as original as the rest of the Y Body understructure.
Raw Aluminum or Epoxy Coating for Tailored Underhood Protection
Builders can opt for a bare aluminum finish to maximize heat rejection through an unrestricted surface, complete with a subtle patina that develops over time. Alternatively, the black epoxy coating seals the metal against moisture, road salts, and airborne contaminants that can accelerate wear. Each finish is applied with strict control over thickness to prevent flaking or gaps that would trap humidity. This choice allows owners to balance cooling efficiency with corrosion resistance based on their climate and maintenance preferences. Both options uphold the classic look of the Corvette engine bay while extending service life.
Lightweight Aluminum Construction for Enhanced Cooling Efficiency
Constructed entirely from premium aluminum, this radiator reduces overall vehicle weight without sacrificing strength. Aluminum's inherent thermal conductivity supports rapid dissipation of heat in demanding conditions, such as canyon carving or extended highway cruising. The slim design preserves underhood space and minimizes fluid volume, which helps the engine reach and maintain optimal operating temperature more quickly. Combined with an automatic transmission coolant circuit, the system delivers consistent temperature control under any load. This intelligent material choice provides a performance oriented solution that aligns with LS swap demands.
