LS Swap Radiator for 1962-1967 Chevy II/Nova X-Body Manual Transmission
When you're pressing an LS engine into the tight confines of a 1962-1967 Chevy II or Nova X Body chassis with a manual transmission the cooling challenge becomes clear and this radiator streamlines installation by aligning inlet and outlet ports to the factory hose locations and tunnel shape. With TIG welded aluminum tanks bonded to a precision built core the assembly sustains high pressure coolant flow and wards off heat buildup even under sustained high load. Its aluminum body also resists rust and stress cracking without adding excessive weight. Manufactured in the United States to original mounting specifications this unit drops in without extra brackets or frame changes.
Optimized Fit for 1962 to 1967 Chevy II and Nova Manual Transmission
This radiator is engineered to align inlet and outlet ports precisely with the factory hose locations and the manual transmission tunnel contour in 1962 to 1967 Chevy II and Nova models. By matching original mounting points, it drops into the X Body chassis without requiring additional brackets or frame modifications. This direct fitment not only reduces installation time but also minimizes the risk of misaligned hoses that can lead to leaks or premature wear. Technicians and hobbyists alike benefit from a straightforward installation process that preserves the vehicle's structural integrity and ensures optimal coolant flow from day one.
TIG Welded Aluminum Tanks for Leak Proof Strength
High grade aluminum tanks are joined to the core using TIG welds, a process that creates exceptionally clean beads with minimal porosity. This level of weld quality prevents coolant seepage and maintains joint integrity under the elevated pressures common to LS engines. As the engine cycles through aggressive temperature changes, these welds resist cracking and fatigue far better than brazed or mechanically crimped assemblies. The result is a durable connection that endures vibration, road shock, and the rigors of spirited driving without compromising reliability.
Precision Core Design for Rapid Heat Dissipation
The full aluminum core employs a tight fin and tube arrangement to maximize surface area in contact with circulating coolant. Aluminum's superior thermal conductivity draws heat away from the engine block evenly, preventing the formation of localized hot spots that can stress gaskets and cylinder walls. In stop and go traffic, this efficient heat rejection keeps the thermostat operating in its ideal band, ensuring a stable engine temperature under all conditions. Even under sustained high load, the core holds its shape and performance, preserving consistent coolant flow and reducing the chance of overheating during spirited runs or towing tasks.
Corrosion Defense with Bare or Epoxy Coating Options
Owners can choose a natural bare aluminum finish or a black epoxy treatment to suit their build vision and environmental demands. The untreated surface forms a self-protective oxide layer that guards against oxidation while allowing for a polished show quality appearance. Alternatively, the epoxy coating creates a moisture barrier that repels road salt, brake dust, and acid rain without hindering thermal performance. Both finishes are applied under strict factory controls for uniform adhesion, resisting peeling and staining so the radiator maintains both its protective qualities and visual appeal over years of use.
