High-Flow Radiator for 1973-1976 Chevy Corvette Y-Body LS Swaps
If you are installing an LS engine and automatic transmission into a 1973 to 1976 Y-Body Corvette this 26 inch wide core radiator with dual fans is engineered to keep coolant temperatures stable under extended highway runs and city traffic. This design slots into the factory mounting points for direct fitment and aligns precisely with LS plumbing while clearing the transmission housing without any custom brackets. A pair of high capacity fans engages once airflow drops below optimal and prevents heat buildup during idling or slow speed driving to maintain consistent engine cooling. Built from welded aluminum in the USA this radiator delivers corrosion resistance and rapid heat rejection for dependable operation on both street and track.
26 Inch Wide Core for Accelerated Thermal Exchange
The 26 inch wide core dramatically increases coolant volume and contact surface, allowing heat to move from the engine into the radiator more quickly under load. By spreading fluid across a larger area, this design minimizes hot spots and ensures uniform temperature distribution, even during extended highway runs or spirited city driving. The expanded core width works in concert with the Y Body chassis design to prevent thermal stratification and reduce the risk of coolant boil over. As a result, drivers enjoy stable operating temperatures when pushing an LS swap to its limits.
Twin Fan Array for Steady Airflow Management
Equipped with two high capacity fans mounted directly to the radiator face, this system senses airflow reduction and engages automatically during idling or low speed traffic. The synchronized fans maintain a constant pull of air through the core, compensating for the lack of natural ram effect when the vehicle slows or comes to a stop. This continuous airflow is critical to clear heat from both the engine and the automatic transmission's torque converter, preventing temperature spikes. The result is consistent cooling performance across stop and go conditions without driver intervention.
Premium Aluminum Construction with Coating Options
Constructed from high quality aluminum, the radiator excels at shedding heat thanks to the metal’s natural conductivity and light weight. Aluminum also offers inherent corrosion resistance, extending service life in harsh road conditions. Customers can choose a raw finish that maximizes thermal transfer or a black epoxy coat that adds a protective barrier against road debris and environmental factors. Each unit is made in the USA under strict quality standards to ensure durability and repeatable performance.
Direct Fitment for 1973 to 1976 Corvette Y Body Swaps
This radiator assembly is engineered to slot into the factory mounting points of a 1973 to 1976 Y Body Corvette without altering core supports or frame rails. Hose connections align precisely with LS plumbing angles and clear the automatic transmission housing, eliminating the need for custom brackets or adapters. The plug and play nature of the design cuts installation time and reduces potential for leaks or misalignment. Overall, the unit simplifies the cooling upgrade process for classic Corvette owners tackling an LS engine swap.
