Radiator for LS Engine Swap in 1990-1996 Chevy Corvette Y-Body
For Corvette owners tackling an LS swap in an 1990 to 1996 Y Body chassis, this radiator steps in to tame cooling demands whether you run an automatic or manual transmission. It is crafted from full TIG welded aluminum and aligns precisely with factory Y Body mount points to streamline installation and maintain consistent coolant routing. Beyond its core layout, this radiator delivers reliable temperature control under spirited driving and stop and go traffic by combining optimal tube spacing with high fin density. Designed and assembled in the USA, it offers corrosion resistance that preserves resale value and meets the needs of both DIY enthusiasts and professional shops.
Precision TIG Welded Aluminum Construction
The radiator's tanks and core are joined using precision TIG welding, creating uniform seams that resist leaks and withstand repeated heat cycles. This method directs a concentrated arc to fuse high-quality aluminum, resulting in joints that maintain strength under engine vibration and pressure fluctuations. The all-aluminum assembly also keeps overall weight down, benefiting chassis balance and handling dynamics. Manufactured in the USA, each weld is inspected for consistency, ensuring that every connection meets rigorous durability standards.
Advanced Core Design for LS Engine Heat Control
Optimal tube spacing and fin density work together to maximize the contact between coolant and air, improving thermal transfer during spirited runs or idle traffic conditions. By channeling coolant uniformly through the core, the radiator quickly dissipates engine heat, protecting critical parts such as head gaskets and water pump seals. The design strikes a balance between flow rate and surface area, so coolant moves efficiently without causing excess back pressure on the cooling system. This approach maintains stable operating temperatures, reducing the risk of overheating under sustained load.
Direct Fitment to Factory Y Body Mount Points
This radiator aligns precisely with original Y Body chassis mounts, enabling a straightforward bolt in installation without drilling or trimming. Matching the factory frame rails and support points means hose connections, fan shrouds, and overflow fittings line up just as they did from the factory. The result is a clean underhood appearance and consistent coolant routing that eliminates guesswork. Both DIY enthusiasts and professional installers save time while ensuring the cooling assembly sits squarely for optimal performance and clearance.
Corrosion Resistance with Dual Finish Options
Choose from a polished bare aluminum surface or a protective black epoxy coating to suit aesthetic and durability preferences. The bare finish showcases the metal's natural luster and reflects engine bay heat, while the epoxy layer forms a robust barrier against moisture, road chemicals, and debris. Both surfaces undergo thorough preparation and curing processes to guarantee even adhesion and long-term resistance to wear. With either option, the radiator sustains its appearance and resale value over years of daily use and spirited driving.
