Aluminum Radiator for LS Engine Swap in 1990-1996 Chevy Corvette
When swapping an LS engine into a 1990 to 1996 Corvette Y Body chassis most builders find that coolant management becomes crucial and the 1984 to 1989 Corvette Radiator (Auto and Manual Trans) delivers precise heat rejection without altering the frame rails. It features a full aluminum core mated to TIG welded tanks for sustained strength through thermal cycling. Installation into the factory mounting points retains original cooling line alignment and removes the need for custom support brackets ensuring a clean engine bay presentation. This radiator supports both automatic and manual transmissions while maintaining steady coolant flow under sustained driving loads.
Precision TIG Welded Aluminum Core for Lasting Structural Integrity
The radiator's tanks and core are joined by TIG welding, a method renowned for creating exceptionally clean and consistent weld beads. This process fuses the aluminum at a molecular level, eliminating weak spots that can develop under repeated temperature changes. As coolant heats up and cools down, the joints remain stable without forming cracks or pinholes. Builders will appreciate that this welding technique also resists vibration and chassis flex, ensuring the radiator holds pressure even during aggressive acceleration or spirited cornering. The result is a robust cooling assembly that stands up to daily driving as well as track use without compromise.
Choice of Bare Aluminum or Black Epoxy Coating for Heat Transfer and Protection
This radiator offers two surface treatments that both maintain excellent thermal conductivity while adding practical benefits. The classic bare aluminum finish showcases the natural metal and simplifies any future repair or inspection of weld seams. Alternatively, the black epoxy coating applies a protective layer that guards against road salt, moisture and flying debris. The epoxy barrier helps prevent oxidation of the core and tanks, extending service life in harsh climates. Either option allows builders to tailor the visual style of their engine bay without sacrificing cooling performance.
Engineered Fin Density and Coolant Flow for Uniform Temperature Control
Fin spacing and internal passages have been carefully calibrated to balance flow resistance and surface area. By optimizing channel dimensions, the radiator promotes even coolant distribution across every square inch of core material. This prevents localized heat buildup and minimizes temperature swings during long highway runs or stop-and-go traffic. The smooth flow path also reduces load on the water pump, contributing to quieter operation and longer pump life. In practice, drivers will notice faster temperature recovery after hard acceleration and more consistent coolant readings under sustained loads.
Direct Fitment to Corvette Y Body Frame for Simplified Installation
Designed specifically for the 1990 to 1996 Chevrolet Corvette Y Body, this radiator mounts directly to the factory support points with no need to alter the rails or fabricate extra brackets. Inlet and outlet ports align precisely with the stock cooling lines, preserving the original routing and avoiding kinks or stress points. The drop-in design streamlines workshop time by eliminating trial-and-error fitting, so builders can focus on finishing details. Once installed, the unit sits securely in the bay, dampening engine vibrations and providing a snug, rattle-free fit that maintains the Corvette's clean factory appearance.
