1977-1982 Chevy Corvette LS Swap Radiator for Automatic Transmission
If you are undertaking an LS series engine installation into a 1977 to 1982 Chevrolet Corvette Y body with automatic transmission, the 1977-1982 Corvette Radiator (Auto Trans) delivers the precise coolant handling you require. Built in the United States, its tanks and core are formed from high-grade aluminum and united by 100 percent TIG welded seams to ensure durable leak resistance under varied operating stresses. Offered in a natural bare aluminum finish or a protective black epoxy coat, this radiator carries a zero fan count so you can specify the airflow solution that matches your setup and driving conditions.
Precision Cooling for Classic Corvette
The 1977-1982 Corvette Radiator for automatic transmission and LS engine applications delivers targeted cooling performance tailored to the demands of a classic front-engine sports car. By matching the original mounting footprint and incorporating a deep core section, it maintains optimal coolant volume and flow rate. Consistent operating temperatures protect head gaskets and bearings, extending the service life of high-output engines while minimizing overheating risk under road or track use. This focused design ensures that both daily drivers and competition builds benefit from reduced thermal stress.
Engineered Construction
Manufactured with premium aluminum tanks and core, this radiator resists corrosion and shrugs off heat cycles that degrade other alloys. The entire assembly is 100% TIG-Welded, creating fully sealed joints that prevent weeping under elevated pressure and thermal cycling. Compared with mixed-metal designs, its homogeneous aluminum structure improves conductivity, allowing rapid heat transfer away from coolant to fins. The lightweight build also helps rebalance front-end weight distribution, enhancing handling without compromising durability. Proudly made in the USA, it meets exacting standards for material quality and workmanship.
Mounting and Compatibility
Designed for seamless integration with MuscleRods mounts, this radiator slots directly into kits developed for LS conversions in 1977–1982 Corvette frames. The engineered bracket clearances ensure proper engine placement and maintain the correct transmission torque angle, preventing driveline vibration and premature joint wear. Factory-style inlet and outlet positions align with stock hoses and transmission cooler lines, simplifying installation. Technicians will find bolt holes and support points positioned to original dimensions, delivering a straightforward swap that aligns both sheetmetal and mechanical systems without trial and error.
