LS Radiator Kit for 1990-1996 Chevy Corvette Y-Body
For builders swapping an LS engine into a 1990 to 1996 Corvette Y-Body chassis, keeping coolant temperatures in check is essential and this 1984-1989 Corvette Radiator (Auto and Manual Trans) delivers that capability with precision heat rejection. Featuring a full aluminum core with TIG welded tanks, it slots directly into the factory Y-Body mounts without altering the frame and supports both automatic and manual transmissions. Optimized fin density and refined internal passages guide coolant through the radiator evenly so engine heat stays controlled during sustained spirited driving or towing. Direct fitment to the stock mounting points removes custom bracket fabrication and helps retain the original engine bay layout for a clean, quiet installation.
Precision TIG Welded Aluminum Tanks and Core
The radiator's tanks and core are joined using TIG welding, a method that delivers uniform weld beads and deep metal fusion. This process creates joints that stand up to engine vibration and repeated thermal cycles without cracking, ensuring coolant remains contained under sustained load. By eliminating potential leak paths, TIG welding supports uninterrupted coolant circulation even during spirited driving or towing. The result is a durable cooling assembly that maintains its integrity over countless heat-up and cool-down cycles.
Classic Bare Aluminum or Black Epoxy Finish
Constructed entirely from aluminum, the radiator core excels at transferring heat while reducing overall weight. Builders can choose the classic bare aluminum look for an authentic metal finish or opt for the black epoxy coating to add a protective barrier against corrosion and road debris. Both surface treatments preserve the radiator's thermal conductivity and help shield internal passages from moisture intrusion. This choice-driven design allows custom installations to maintain visual consistency without compromising heat rejection performance.
Engineered Fin Density and Coolant Flow Optimization
Internal passages and fin spacing have been meticulously balanced to ensure even coolant distribution across the entire core. By refining channel dimensions, the radiator maximizes surface contact between the coolant and aluminum fins, smoothing flow resistance and enhancing heat exchange efficiency. This thoughtful design reduces the formation of hotspots during low-speed traffic or extended high-speed runs, keeping engine temperature uniform. Consistent flow also lessens strain on the water pump, supporting reliable operation under all driving conditions.
Direct Bolt-In Fitment for Corvette Y Body Chassis
This radiator is crafted to align precisely with the factory mounting points on 1990–1996 Chevy Corvette Y Body frames, allowing installation without modifying the frame or fabricating custom brackets. Clear alignment features enable the inlet and outlet to attach directly to the original frame supports, delivering a solid, quiet fit. The straightforward fitment process saves valuable workshop time and retains the Corvette's original engine bay layout. As a result, builders achieve professional-level integration while benefiting from enhanced cooling capacity.
