LS Radiator with Fans for 1973-1976 Chevy Corvette Y-Body 26 Inch Wide Core
When installing an LS engine and automatic transmission into a 1973 to 1976 Y-Body Corvette this 26 inch wide core radiator with dual fans addresses the most demanding cooling challenges. Designed for direct slotting into original mounting points it matches LS plumbing alignment and clears the transmission housing without any custom brackets. Each fan activates automatically when airflow drops below optimal to maintain coolant flow during city traffic or extended idling. Constructed from welded aluminum in the USA this assembly offers corrosion resistance and rapid heat rejection for dependable performance on street or track.
Enhanced Thermal Exchange with 26 Inch Core
The expansive 26 inch wide core delivers a significant increase in coolant volume and surface area, enabling more efficient heat transfer from an LS engine under sustained load. By channeling fluid evenly across a broad network of cooling fins and tubes, this design prevents localized hot spots that can occur during spirited driving or high ambient temperatures. The generous core depth also maintains stable flow rates, reducing the risk of thermal stratification at highway speeds. Whether you are cruising long distances or pushing the engine on winding back roads, the extra capacity helps keep coolant temperatures within the optimal range. This continuous temperature control safeguards internal components and preserves peak performance over extended use.
Automated Dual Fan System for Consistent Airflow
Equipped with two high capacity fans mounted directly to the radiator face, this setup senses drops in airflow and engages automatically when engine speed or vehicle motion falls below ideal levels. The synchronized operation of both fans maintains a steady pull of cool air through the core during idle or slow city driving, compensating for the absence of natural ram cooling. This active management extends to protecting the automatic transmission's torque converter, which can generate its own heat under load. By eliminating the need for driver intervention, the system ensures that heat never builds up to damaging thresholds. The result is reliable cooling performance in both stop and go traffic and on the track.
Aluminum Structure with Bare or Black Epoxy Finish
Constructed entirely from high quality aluminum, the radiator core and end tanks take full advantage of the metal's superior conductivity and light weight. Aluminum's natural resistance to rust and corrosion helps maintain long term integrity, even in regions prone to road salt or high humidity. Customers have the choice of a raw bare aluminum finish for maximum thermal transfer or a black epoxy coat that adds scratch resistance and protection against environmental contaminants. Each finish undergoes a thorough quality check in the United States to ensure a flawless surface and precise dimensional tolerances. The combination of material selection and finishing options results in a durable assembly that stands up to the demands of daily driving and competitive events.
Plug and Play Fitment for 1973 to 1976 Corvette Y Body
This radiator is engineered for direct fitment into the original support structure of a 1973 to 1976 Corvette Y Body, eliminating the need for any custom brackets or modifications. Hose connections align precisely with LS plumbing angles, and the design clears the automatic transmission housing without interference, streamlining installation and reducing leak points. The factory mounting heights and core support tabs remain untouched, preserving chassis integrity and simplifying assembly. As a result, installers can achieve a professional grade coolant system with minimal labor and no compromise to structural components.
