LS Radiator for 1973-1976 Chevy Corvette Y-Body with 26 Inch Wide Core and Fans
Installing an LS engine and automatic transmission in a 1973 to 1976 Y Body Corvette demands precise coolant flow and heat rejection solutions that this 26 inch core radiator with built in fans delivers. By matching original mounting points with LS hose connections and clearing the transmission housing there is no need for custom brackets or tedious modifications. Featuring dual cooling fans that activate automatically at low airflow the assembly keeps coolant temperatures steady in slow traffic and under hard acceleration. Constructed from welded aluminum in the USA this radiator offers corrosion resistance and rapid heat rejection so drivers can rely on stable performance whether they are on the open road or the track.
Optimized Heat Rejection via 26 Inch Wide Core
The expansive 26 inch wide core dramatically increases coolant volume and surface exposure, allowing more heat to transfer away from the LS engine under heavy load. Fluid travels through a dense network of precision aligned tubes and fins that disperse high temperature zones quickly, preventing hot spots even during extended track sessions. The generous width also maintains uniform flow across the entire core face, reducing the chance of thermal layering when cruising at highway speeds. This continuous circulation keeps coolant temperatures within the ideal operating window, safeguarding internal components against premature wear and preserving peak performance over long drives.
Dual Fan Activation for Reliable Airflow Control
Equipped with two high capacity fans directly mounted to the radiator face, this system senses drops in vehicle speed or engine led airflow and activates automatically to maintain steady air delivery. Dual fan operation ensures that cool air is drawn evenly through the core at idle, in heavy traffic and on steep grades where natural ram cooling is minimal. This proactive management extends to the automatic transmission's torque converter area, dissipating heat generated under load and preventing fluid breakdown. By eliminating manual intervention, the assembly delivers consistent cooling in all conditions, so drivers can focus on the road without concern for rising temperatures.
Durable Aluminum Body and Coating Varieties
Constructed entirely from high quality aluminum, the radiator harnesses the metal's superior thermal conductivity to move heat out of the cooling system with minimal weight penalty. Aluminum's innate resistance to rust and electrochemical corrosion increases service life, especially in climates subject to moisture or road treatment chemicals. Customers may choose a bare aluminum finish for maximum heat transfer or opt for a black epoxy coat that adds scratch resistance and shields against environmental contaminants. Each surface is inspected in the USA for dimensional accuracy and finish integrity to ensure a flawless fit and lasting appearance.
Seamless Integration for 1973 to 1976 Corvette Y Body
This radiator assembly is engineered for direct slotting into the stock support structure of a 1973 to 1976 Corvette Y Body without any custom brackets or frame alterations. LS style hose connections align precisely with original plumbing angles, while the core and shroud clear the automatic transmission housing to prevent interference. Factory mounting tabs and brace points remain untouched, preserving chassis rigidity and simplifying installation. As a result, professional grade coolant performance is achieved with minimal labor and no compromises to the vehicle's structural components.
