26in Wide Core LS Radiator for 1973-1976 Chevy Corvette Y-Body
Swapping an LS motor into a 1973 to 1976 Corvette Y-Body manual transmission chassis exposes the cooling system to demands beyond factory limits and this radiator is built to keep heat in check under those conditions. Featuring a 26 inch wide core and dual electric fans, it bolts directly into the Y-Body frame with factory aligned mounts and plug and play fan connectors. By combining aluminum construction with precise flow paths, the unit ensures rapid heat transfer away from the LS engine and resists corrosion for long service life. Installation remains straightforward so you can focus on finishing your swap rather than custom fitting components.
Precision Core Design Maximizes Radiator Surface Area
Expanding the core width to 26 inch wide core significantly increases the contact area between coolant and ambient air, improving heat rejection under all driving conditions. This precision welded core directs flow evenly across the tubes, eliminating hot spots and maintaining consistent engine temperatures during spirited runs or heavy traffic. By optimizing fin density and tube spacing, it sustains peak cooling efficiency without adding bulk or weight to the Y-Body chassis.
Dual Electric Fans Deliver Consistent Airflow at Low Speeds
The two high performance fans mount directly to the radiator and operate based on coolant temperature signals, ensuring airflow even when vehicle speed is low or stopped. Their full-coverage placement across the wide core prevents heat soak and sustains engine output during extended idle periods or track sessions. Thanks to plug and play connectors and factory-aligned mounts, installation is seamless with no need for wire splicing.
High Quality Aluminum Construction Balances Strength and Weight
Crafted from premium aluminum, the radiator combines excellent thermal conductivity with a durable structure that resists vibration and stress. Aluminum's natural corrosion resistance reduces the risk of internal pitting and maintains flow efficiency over time. Precision welding at each joint creates leak-proof seals that endure the rigors of high coolant pressure and repeated heat cycles.
Coating Options Protect and Enhance Engine Bay Appearance
Choose the bare aluminum finish for maximum radiant heat transfer or select the black epoxy coating to add an extra barrier against moisture and road salts. Both finishes are applied in house to ensure uniform coverage and long term durability. The natural finish highlights the metallic texture while the epoxy option complements darker engine bay components for a clean, factory-quality look.
