LS Swap Radiator for 1977-1982 Chevy Corvette Y-Body
For model years 1977 through 1982 Y Body Corvettes fitted with an LS engine and automatic transmission, this radiator maintains precise coolant flow and guards against overheating under sustained load. Its high grade aluminum construction and 100 percent TIG welded core deliver efficient heat rejection while resisting corrosion over time. Designed to occupy the factory mounting points, it preserves original hose positions for a hassle free installation. Aluminum's lightweight mass supports nimble handling and keeps engine temperatures in check during spirited runs.
Precision TIG Welded Core for Reliable Leak Resistance
Every weld in this radiator utilizes TIG welding to deliver uniform bead geometry and deep penetration between tanks and fins. This method yields seams that withstand repeated thermal cycles and engine vibration without compromising the coolant seal. As a result, the radiator maintains its structural integrity under continuous load, protecting the engine from potential overheating. The meticulous American welding process also improves the overall life span of the cooling system.
Pure Aluminum Construction for Superior Heat Rejection
Built entirely from high quality aluminum, this radiator maximizes thermal conductivity to pull heat swiftly away from the engine coolant. Its lightweight frame reduces front end mass, granting more responsive steering characteristics on the road. Aluminum's innate resistance to oxidation prevents the formation of internal scale, preserving coolant flow over many driven miles. Together, these traits ensure stable operating temperatures during spirited driving sessions.
Choice of Bare Aluminum or Epoxy Coating for Lasting Protection
Opt for the classic bare finish to let aluminum's natural oxide layer guard against corrosion or select the black epoxy option for an extra moisture barrier. Both finishes are applied under strict quality controls to provide uniform coverage and superior durability in harsh environments. The bare version maintains a traditional metal appearance, while the epoxy finish resists road salt and debris. Each coating choice allows builders to match their Corvette's style without sacrificing performance.
Direct Fit Design Simplifies LS Engine Swap Installation
Engineered specifically for 1977–1982 Corvette Y body frames with automatic transmissions, this radiator installs using the factory mounting locations and original hose fittings. By preserving stock attachment points, it eliminates the need for custom brackets or rerouting coolant lines. This plug and play approach cuts down on labor time and potential alignment issues. Enthusiasts can undertake their LS swap knowing the cooling system will integrate seamlessly into the chassis.
