LS Radiator with Dual Fans for 1977-1982 Chevy Corvette
If you're fitting an LS engine and automatic transmission into a 1977 to 1982 Y-Body Corvette you need a cooling assembly that stands up to traffic and track demands. This radiator features a TIG welded aluminum core and integrated transmission cooler that installs into factory frame mounts without trimming. Its dual brushless fans mount directly to the fin pack and pull air through the fin stack at low vehicle speed or under heavy load while keeping noise to a minimum. Built in the USA from corrosion resistant aluminum, this radiator balances lightweight design with the durability required for street and circuit use.
Precision Alignment with Factory Frame Brackets
The radiator assembly is engineered to fit directly into the original mounting locations on 1977 to 1982 Y Body Corvettes without any trimming or adapter plates. Integrated fittings for 4L60E and 4L80E transmission cooler lines allow hoses to connect seamlessly, eliminating the need for special adapters or cutting of factory components. This precise alignment preserves under hood clearance, keeps steering and suspension geometry intact, and ensures coolant and transmission fluid flow follow the intended factory routes. By maintaining the factory frame geometry, installers benefit from shorter assembly times and greater confidence in a consistent fit.
TIG Welded Aluminum Core for Reliable Heat Transfer
Both tanks and the high capacity core are machined from premium aluminum and joined by TIG welding, creating uniform bonds without filler irregularities. This construction resists warping and prevents leaks through repeated heating and cooling cycles while the natural conductivity of aluminum accelerates heat rejection into the airflow. A dense fin pack design further boosts thermal efficiency by maximizing surface area for heat exchange, yet the overall weight remains low to improve the car's power to mass ratio. The combination of a durable weld process and a finely tuned core geometry delivers stable engine temperatures in daily driving and during extended track sessions.
Dual Brushless Fans for Consistent Airflow Under Load
The pair of brushless electric fans are mounted to the fin stack to pull cool air directly through the core whenever vehicle speed drops or under heavy load conditions. Brushless motor technology reduces noise levels and eliminates brush wear, offering years of service without bearing failure or motor degradation. Active cooling at idle prevents heat soak, while the fans' airflow capacity ensures coolant temperatures remain within the ideal range during stop and go traffic or spirited road driving. This reliable fan system protects the engine from thermal stress and supports consistent performance in a variety of driving scenarios.
Finish Options for Corrosion Protection and Thermal Efficiency
Owners can choose a bare aluminum finish to maximize natural heat rejection or select a black epoxy coating for enhanced corrosion resistance in harsh environments. The epoxy adheres to the aluminum surfaces without blocking airflow channels or reducing thermal conductivity, and it forms a barrier against moisture, road chemicals, and debris. This protective layer prevents surface oxidation and makes routine cleaning simple, extending the service life of the radiator. By offering both finish options, the design accommodates enthusiasts who demand maximum cooling or those who require extra durability in challenging conditions.
