1973-1976 Chevy Corvette Y-Body LS Radiator for Engine Swap
When outfitting a 1973-1976 Y-Body Corvette with an LS engine and automatic transmission the stock radiator often struggles to maintain coolant temperature under spirited driving. The 26 inch wide core radiator with fans brings expanded coolant surface area and dual fans to keep engine heat in check whether you are cruising on the highway or idling at a stoplight. Designed for direct fitment in the factory mounting points the assembly aligns perfectly with LS plumbing and clears the transmission without modifications. Built from welded aluminum in the USA it delivers consistent heat rejection and corrosion resistance for reliable performance over the miles.
Optimized 26 Inch Core for Superior Thermal Management
The 26 inch core boosts coolant volume and surface area, allowing heat to dissipate rapidly under heavy loads and scorching summer days. This wider design lowers the risk of hotspots by ensuring even temperature distribution across the entire radiator face. Drivers will notice steady coolant temperatures during spirited highway runs and in stop-and-go traffic. By expanding contact area between coolant and aluminum, the system maintains stable operation even when the LS engine is pushed to its limits.
Dual Fan Array Delivering Consistent Airflow
Mounted directly to the radiator, the pair of high capacity fans activate as soon as airflow drops below optimal levels, such as during idling or in city traffic. Their synchronized operation ensures a continuous pull of air through the core, preventing heat buildup when natural ram air is insufficient. This setup is especially beneficial for vehicles with automatic transmissions, where extra heat from the torque converter can challenge cooling systems. The result is reliable engine temperature control across varied driving conditions.
Robust Aluminum Construction with Finish Versatility
Built from premium aluminum, this radiator leverages the metal's excellent thermal conductivity and inherent corrosion resistance to accelerate heat rejection and extend service life. Customers can choose between a classic bare surface that maximizes raw conduction properties or a black epoxy coat for added protection against environmental wear. Each option is fabricated in the USA under strict quality control, ensuring consistency from raw material through final assembly. This combination of material and finish delivers both performance and longevity.
Plug and Play Fit for 1973 to 1976 Y Body Corvettes
Engineered specifically for the Y Body chassis with an automatic transmission, the radiator installs into the factory mounting points without core support modifications. Hose locations match LS plumbing angles precisely, cutting install time and reducing the need for custom brackets. Built to clear the transmission housing, the assembly streamlines the swap process and minimizes potential interference. This direct fit design simplifies the upgrade of the cooling system in classic Corvettes.
