LS Radiator for 1977-1982 Chevy Corvette with Automatic Transmission
Swapping an LS V8 into a late seventies Corvette with automatic transmission demands a radiator that keeps coolant circulating under sustained load and fits the chassis without modification, maintaining stable temperatures during both highway runs and spirited driving. The 1977-1982 Corvette Radiator (Auto Trans) features a 100 percent TIG welded aluminum core and tanks to shed heat quickly and resist corrosion under high demand. By retaining original hose connections and mounting points, installation avoids custom brackets or line rerouting, preserves steering feel and chassis balance and delivers rapid heat rejection whether cruising or pushing on road.
Precision TIG Welding for Radiator Durability
Every joint on this radiator employs 100% TIG welding to fuse aluminum tanks and core with exceptional strength. By directing a focused arc, weld seams experience deep penetration and very low distortion, which prevents cracks or separation under repeated heating and cooling cycles. This precise process also eliminates the common weak points found in mass-produced radiators, resulting in a leak-free seal that endures road vibration and engine movement. The outcome is a robust assembly that maintains structural integrity and consistent coolant containment over many seasons of spirited driving.
Superior Heat Rejection from Pure Aluminum Core
Constructed entirely from premium aluminum, the heat exchanger excels at conducting thermal energy away from coolant in demanding conditions. Aluminum's natural conductivity stops hotspots from forming, helping the engine hold stable operating temperatures even under sustained load or high ambient heat. Its light weight trims mass at the front of the Corvette, sharpening steering response and preserving the vehicle's intended balance. Additionally, aluminum resists oxidation inside flow passages, which minimizes scale buildup and helps sustain peak cooling capacity over time.
Dual Finish Options for Lasting Corrosion Resistance
Owners may choose a bare aluminum finish or a black epoxy coating to suit their environment and aesthetic preferences. The uncoated variant relies on aluminum's own oxide layer to ward off rust, while the epoxy barrier adds extra protection against road salt, moisture, and debris. Both finishes undergo careful inspection for even coverage and adhesion, so no extra surface treatment is required prior to installation. This flexibility ensures reliable corrosion defense without compromising the radiator's cooling performance.
Seamless Integration with Corvette Chassis and Hoses
Designed specifically for the 1977–1982 Chevy Corvette Y body with automatic transmission, this radiator drops into all factory mounting points and retains original hose fittings. Eliminating the need for custom brackets or line rerouting, it preserves the Corvette's steering feel and frame geometry. By matching stock attachment locations and fluid pathways, coolant flow dynamics remain exactly as the carmaker intended. The plug-and-play fitment guarantees quick installation and dependable temperature control from first start through every highway run or weekend track session.
