LS Radiator with Fans for 1977-1982 Chevy Corvette (Manual Trans)
Cooling demands climb when an LS engine is dropped into a 1977-1982 Chevy Corvette manual transmission model, and this radiator assembly with dual fans meets that requirement. Designed for precise Y Body frame alignment, the aluminum core and tanks bolt in using factory bracket locations and hose ports, eliminating sheet metal trimming and preserving factory structure. Built around a full TIG welded core and a prewired fan shroud, it maintains steady airflow at low speeds where natural cooling is insufficient and the harness plugs directly into the stock loom for error free integration. Ultimately, corrosion resistant aluminum construction reduces front end mass for improved handling and plug and play installation keeps coolant temperatures in check whether crawling through traffic or pushing the chassis on track.
Precision Alignment with 1977-1982 Y Body Frame
This radiator is tailored to the unique geometry of late-seventies Corvette Y Body chassis, ensuring that inlet and outlet ports align precisely with LS engine hose locations. Each mounting boss corresponds to factory bracket points, so you can bolt it in without trimming original sheetmetal or fabricating custom brackets. By preserving the stock frame rails and hose paths, installation time is cut drastically and the integrity of the Corvette's front structure remains intact. The snug fit also prevents vibration under hard acceleration, giving you confidence in both everyday driving and spirited track sessions.
TIG Welded Aluminum Core for Superior Heat Exchange
High-grade aluminum tanks and core are joined using tungsten inert gas welding, creating seams that resist leaks and endure repeated thermal cycles without fatigue. Aluminum's excellent conductivity allows rapid transfer of heat from coolant to ambient air, while its low weight contributes to improved front-end balance and agile handling. With precise fabrication, the core maintains consistent wall thickness and flow passages, optimizing coolant flow rates. The corrosion-resistant nature of aluminum further extends service life, even in humid or salty environments.
Integrated Dual Fan Array for Steady Airflow
Two 12-volt fans are preinstalled on a custom shroud designed to channel airflow uniformly across the entire core surface, eliminating hotspots when natural ram air is insufficient. The plug and play wiring harness plugs directly into the factory loom, simplifying electrical integration and reducing the risk of wiring faults. Both fans engage together at low speeds, maintaining stable coolant temperatures during stop-and-go traffic or extended idling. At higher vehicle speeds, the streamlined shroud design produces minimal drag while enhancing heat rejection.
Finish Selections for Enduring Protection and Visual Appeal
Choose the classic bare aluminum option to maximize thermal emissivity and highlight an authentic restoration look, or specify the black epoxy coating for added resistance to moisture, road chemicals, and engine bay contaminants. Each finish is applied without adding thickness that could create thermal barriers, so cooling performance remains uncompromised. The epoxy variant also resists chipping and fading, ensuring the core retains its clean appearance through years of use. Both choices allow you to blend functionality with a tailored engine bay presentation.
