LS swap radiator for 1990-1996 Chevy Corvette Y-Body
The 1984-1989 Corvette Radiator (Auto and Manual Trans) is engineered to handle the extra heat output of an LS engine conversion in a 1990-1996 Chevy Corvette Y Body chassis. It features a full aluminum core with precision TIG welded tanks that resist corrosion and maintain structural integrity under sustained load. Built to slot into factory Y Body mounting points without modification the radiator simplifies installation for both automatic and manual transmission applications. By optimizing fin density and internal passages it manages coolant temperature under spirited driving and towing so engine heat stays in check.
Precision TIG Welded Construction for Reliable Sealing
The radiator tanks and core are joined using TIG welding technology, producing consistent weld beads and deep metal fusion. This method creates robust joints that withstand engine vibration and repeated thermal cycles without cracking. Uniform welds eliminate potential leak paths and keep coolant flowing smoothly even under high load. The result is a dependable cooling solution that resists seepage during spirited driving or towing demands.
Full Aluminum Core with Protective Coating Choices
Constructed entirely from high quality aluminum, the core offers exceptional heat conductivity and reduced weight compared with traditional materials. You can select the classic bare finish for an authentic metal look or opt for the black epoxy layer to add a durable barrier against corrosion. Both finishes preserve the aluminum's ability to transfer heat while shielding internal passages from moisture and road debris. This flexibility lets builders match appearance preferences without compromising thermal performance.
Optimised Internal Passages for Consistent Temperature Control
Internal coolant channels have been engineered to balance flow resistance with surface contact across the fin array. By refining passage dimensions and fin spacing, the design smooths coolant movement and maximises heat exchange area. This approach reduces hotspots during stop and go driving or extended high speed runs, keeping the LS engine running at an even temperature. Consistent flow also reduces strain on the water pump, ensuring reliable operation on every trip.
Direct Fitment to 1990 to 1996 Y Body Mount Points
This radiator is configured to align perfectly with the factory mounting locations in 1990 to 1996 Corvette Y Body chassis for automatic transmissions. Installation requires no bracket fabrication or cutting, simplifying the swap and saving valuable workshop time. Clear alignment instructions guide you to secure the inlet and outlet to the original frame supports for a solid, quiet fit. The direct drop-in design preserves the Corvette's chassis geometry while delivering enhanced cooling capacity.
