LS Radiator for 1977-1982 Chevy Corvette Manual Transmission
Swapping an LS engine into a 1977 through 1982 Corvette Y Body with a manual transmission calls for a radiator that aligns with factory brackets while delivering consistent coolant flow under sustained operation. The 1977-1982 Corvette Radiator (Manual Trans) pairs thick aluminum tanks, dense fin rows and fully TIG welded seams to reject heat quickly and resist leaks during spirited driving. By matching stock frame rails and hose ports it installs in minutes without adapter plates or brackets. With corrosion resistance built in and a light weight assembly that preserves the car's handling balance it ensures reliable cooling for road or track use.
Precision TIG Welding for Durable Seam Integrity
This radiator is assembled using 100 percent TIG welding to join premium aluminum tanks and core panels with exceptional precision. TIG welding employs a non consumable tungsten electrode and controlled heat input to create deep fusion without introducing porosity or weak points in the seams. As a result, the bond resists cracking and coolant leaks under repeated thermal cycling and pressure spikes common in spirited driving. Crafted in the USA, each uniform weld bead contributes to a service life that stands up to the demands of LS engine powerbands.
Dense Fin Array and Aluminum Core for Efficient Cooling
The core of this unit features a closely spaced fin configuration integrated with brazed coolant passages to boost heat dissipation. Aluminum's high thermal conductivity moves engine heat into the airflow quickly, while the dense fin layout maximizes surface contact without impeding radiator flow. Even in heavy traffic or extended track use, the design prevents hotspots by maintaining even coolant distribution from end to end. At the same time, the overall lightweight construction helps preserve the Corvette's original handling balance.
Corrosion Protection via Bare Aluminum or Black Epoxy Finish
Owners can choose a classic bare aluminum surface for direct heat transfer or opt for a robust black epoxy finish to guard against moisture, road grit, and environmental contaminants. The bare option lets aluminum work at peak efficiency, while the epoxy coating adds a tough barrier that resists chips and salt without hindering cooling. Both treatments undergo rigorous bonding tests and thermal stress cycles to ensure lasting adhesion and performance. This choice lets installers match the engine bay styling or prioritize protection in coastal and winter climates.
Direct Alignment with 1977 to 1982 Corvette Frame Rails and Ports
Engineered specifically for the 1977 to 1982 Corvette Y body with manual transmission, this radiator uses stock mounting locations and factory hose ports to eliminate adapter plates or custom brackets. By fitting directly into the original frame rails, it preserves the factory mounting geometry and maintains clearance for the transmission tunnel and steering linkage. Installation takes only minutes, reducing labor time and avoiding interference or hose kinks. The precise fit allows enthusiasts to focus on wiring, drivetrain tuning, and enjoying an authentic swap experience.
