LS Swap Radiator with Fans for 1977-1982 Chevy Corvette
For any LS engine swap into a 1977 to 1982 Y-Body Corvette with an automatic transmission a radiator assembly must offer high coolant volume alongside an integrated transmission cooler and dual fans. The 1977-1982 Corvette Radiator (Auto Trans) with Fans features a TIG welded aluminum core and tanks that resist corrosion and repeated heat cycles while fitting into factory frame brackets for a plug in installation. Direct fittings for 4L60E and 4L80E cooler hoses speed plumbing tasks and eliminate adapter kits or trimming work. Dual brushless fans pull air through the fin stack at low speed traffic and under heavy load to maintain stable coolant flow and precise temperature control during stop and go driving or track sessions.
Precision Mounting and Direct Transmission Cooler Integration
The radiator assembly is designed to align precisely with the original frame brackets on 1977 to 1982 Y Body Corvettes, so no trimming or adapter plates are required. Direct fittings for 4L60E and 4L80E cooler lines drop right into place, eliminating the need for special hoses or cutting. This exact alignment reduces installation time and ensures that coolant and transmission fluid routing follow factory paths, preserving under hood clearance and avoiding interference with steering or suspension components.
TIG Welded Aluminum Core for Reliable Thermal Management
Constructed entirely from high quality aluminum, the core and tanks are joined with TIG welds that create a continuous metal bond free of filler irregularities. This technique resists leaks and warping under repeated heat cycles, while the inherent conductivity of aluminum accelerates heat transfer through the fin stack. The sturdy but lightweight build helps maintain steady engine temperature in both daily commuting and extended track use, and contributes to a favorable power to weight ratio.
Dual Brushless Fans for Consistent Airflow in Traffic and Track Conditions
Mounted directly to the fin pack, two brushless electric fans draw cool air over the core at low vehicle speed and under heavy load. The brushless motor design reduces noise and wear on bearings, delivering years of silent operation and uniform airflow. By actively pulling air even when the car is stopped, this fan setup prevents heat soak during traffic and provides the airflow needed for spirited driving, ensuring coolant temperatures remain within optimal range under varied conditions.
Optional Bare Aluminum or Epoxy Coating for Corrosion Resistance
Owners can choose the raw aluminum finish to maximize heat rejection or select a black epoxy coating for enhanced durability in corrosive environments. The epoxy layer adheres seamlessly to the aluminum surface without blocking air channels or impeding thermal conductivity. This treatment resists moisture, road salt, and surface oxidation, simplifying maintenance and preserving the radiator's structural integrity in regions where exposure to chemicals and abrasion is common.
