LS Engine Radiator for 1990-1996 Chevy Corvette Y-Body
Whether you are rebuilding an LS motor in a 1990 to 1996 Chevy Corvette Y Body chassis or seeking reliable temperature control under spirited driving you will find the 1984-1989 Corvette Radiator (Auto and Manual Trans) engineered to tackle higher heat loads while matching original mounting points. Featuring TIG welded aluminum core and tanks, this radiator resists corrosion and maintains coolant flow through parallel passages to minimize hot spots during city traffic or highway cruising. Installation aligns directly with factory brackets without trimming panels, positioning hoses fan shrouds and overflow connections exactly where they belong. Designed to uphold stable engine temperatures this radiator delivers straightforward fitment and lasting performance.
Precision TIG Welded Aluminum Assembly
The radiator features 100 percent TIG welded high grade aluminum tanks and core. TIG welding uses a focused tungsten arc to fuse metal at a precise melting point, producing uniform seams that resist leaks under constant engine vibration and pressure cycles. By eliminating filler contamination and oxide inclusions this method ensures a strong bond that withstands fatigue and thermal cycling. The all aluminum assembly not only reduces weight compared to steel units but also helps maintain chassis balance and improves handling characteristics. Aluminum's natural corrosion resistance is further enhanced by clean weld seams that limit potential corrosion sites. Every weld bead undergoes thorough quality inspection to ensure durability whether the car sees daily driving or track duty.
Optimized Core Design for Superior Cooling Efficiency
The core is built with precise tube spacing and high fin density to maximize contact between coolant and moving air. Parallel flow passages distribute coolant evenly across the entire surface, reducing hot spots during stop and go traffic or sustained highway cruising. This uniform distribution lowers thermal gradients that can lead to localized overheating and component stress. High fin density increases surface area without creating excessive restriction, balancing flow efficiency with cooling capacity. The design promotes rapid heat rejection and stable engine temperature under varying load conditions. Consistent operating temperatures protect gaskets, seals and internal components, extending the life of the LS engine.
Factory Aligned Fitment in Y Body Chassis
This radiator installs directly to the original mount points on 1990 to 1996 Corvette Y Body frames, requiring no trimming or adapter plates. Mounting holes align perfectly with factory brackets so hoses, fan shrouds and overflow connections fit without modification. Preserving the stock underhood layout helps maintain proper hose bend radii and prevents stress on fittings. The direct fit approach not only saves installation time but also retains the factory look and service access. Whether you are a seasoned mechanic or a home enthusiast, the streamlined process minimizes potential mistakes and downtime.
Coating Options for Long Term Protection
Choose between a natural bare aluminum finish that reflects heat within the engine bay or a black epoxy coating that repels moisture and road chemicals. Both surfaces are prepared under controlled conditions, with careful cleaning and pre treating to ensure the finish bonds evenly across the core and tanks. The bare finish showcases the metal grain and allows visual assessment of weld integrity; the epoxy option adds a protective barrier against corrosion from salt, debris and fluids. Epoxy coating also resists minor chips and scratches that can occur during shipping or installation. By selecting the right finish for your driving environment you preserve both performance and appearance. This protective layer helps maintain resale value and keeps the radiator looking factory fresh for years.
