LS Swap Radiator for 1962-1967 Chevy II/Nova X-Body Manual Transmission
Installing an LS engine into a 1962-1967 Chevy II or Nova manual transmission calls for a cooling solution built to handle increased heat loads and confined engine bay space, and the 1962-1967 Chevy II Radiator (Manual Trans) is engineered to meet that need. At the heart of this design is a full aluminum core and tanks that are TIG welded to resist corrosion and prevent stress cracks under high coolant pressures. Installation follows original mounting points to preserve X-Body chassis geometry and ensure factory fittings align precisely with stock hoses.
Uniform TIG Welded Aluminum Structure for Leak Protection
The radiator's tanks and core are fabricated using full TIG welded aluminum, creating joints with exceptional penetration and uniform bead appearance. This welding technique minimizes porosity and virtually eliminates potential leak paths that can emerge under repeated thermal cycling in an LS swap. With seamless transitions between the core and tank walls, the assembly resists stress cracking even when operating at elevated coolant pressures. By relying on high quality aluminum throughout, the unit achieves consistent strength and rigidity without adding excess weight. Such construction also provides resistance to corrosion from coolant additives and environmental exposure, ensuring reliable service over many seasons of spirited driving.
Full Aluminum Core Design for Rapid Heat Dispersion
At the heart of this radiator is a full aluminum core that leverages the metal's natural conductivity to draw heat away from the LS engine more efficiently than traditional copper units. A fine tube configuration expands the total surface area in contact with coolant, allowing internal temperatures to remain stable under heavy load or in stop and go traffic. By guiding coolant through closely spaced channels, the core maintains uniform flow and avoids hot spots that can stress engine components. Its lightweight nature also helps preserve the balance of the front axle on the X body chassis, which is critical for predictable turn in and cornering behavior. The overall assembly is designed to work seamlessly with the original mounting points and factory hose connections, making it a direct fit in a 1962–1967 Chevy II or Nova manual transmission application.
Dual Finish Choices Deliver Corrosion Defense and Visual Appeal
Owners can choose between a classic bare aluminum face or a black epoxy finish to suit both style and durability needs. The untreated aluminum option forms a natural oxide layer that stands up to oxidation and can be polished to a bright sheen for a show-ready look. Alternatively, the epoxy layer provides an extra moisture barrier that resists road salt and acid rain without impeding heat rejection. Both finishes are applied under controlled conditions to ensure even coverage and adhesion, preventing peeling or flaking over time. This dual approach allows enthusiasts to tailor the radiator's appearance while maintaining full thermal performance and long-term corrosion resistance.
