LS Swap Radiator for 1977-1982 Chevy Corvette Auto Transmission
When installing a modern LS V8 into a 1977 to 1982 Corvette Y body with automatic transmission the 1977-1982 Corvette Radiator (Auto Trans) maintains precise coolant circulation under sustained load. Built with a 100 percent TIG welded aluminum core this unit rejects heat rapidly while resisting corrosion for consistent operation over many miles. It occupies factory mounting points and retains original hose fittings to avoid custom brackets or line rerouting. Aluminum's light weight trims front end mass to support sharper steering feel and stable temperature control during spirited runs.
Precision TIG Welding for Structural Reliability
The radiator features a 100 percent TIG welded aluminum core and tanks, ensuring each joint is fused with deep penetration and minimal distortion. By using a controlled arc method, weld seams resist cracking and warping under thermal cycling, which is critical when coolant temperatures fluctuate during spirited driving. This precise fusion method also eliminates weak points that can lead to leaks, giving sustained peace of mind over thousands of miles. The result is a robust assembly that stands up to vibration, road impacts, and repeated heating and cooling without sacrificing fit or performance.
High Quality Aluminum Core for Fast Heat Rejection
Constructed from pure high quality aluminum, the core excels at conducting heat away from engine coolant with remarkable speed. Aluminum's natural thermal conductivity prevents hotspots that can compromise engine output or cause coolant boil over under heavy load. The lightweight assembly lowers mass at the nose of the Corvette, translating into sharper steering response and balanced handling. In addition, aluminum's inherent resistance to oxidation helps maintain steady coolant flow by reducing scale buildup inside passages.
Protective Coating Options for Corrosion Guard
Owners can select either a bare aluminum finish or a tough black epoxy coating to match environmental conditions and visual preference. The bare option relies on the metal's own oxide layer to ward off corrosion, while the epoxy barrier adds extra protection against road salt, moisture, and debris. Both finishes undergo stringent inspection to confirm even coverage and adhesion, so no additional treatment is required before installation. This flexibility lets enthusiasts balance style and protection without affecting cooling efficiency.
Seamless Integration with Corvette Chassis and Hose Interfaces
Specifically designed for the 1977 to 1982 Chevy Corvette Y-body with automatic transmission, this radiator drops into the original mounting points and retains stock hose connections. There is no need for custom brackets or rerouting of factory lines, which speeds installation and preserves the chassis geometry. By matching the factory attachment locations and fluid fittings, coolant flow dynamics remain consistent with the Corvette's intended design. The plug and play nature of this unit ensures reliable performance and stable temperatures from the first start through every highway cruise or track session.
