1973-1976 Chevy Corvette LS Swap Radiator 26-inch Wide Core with Fans
When you swap an LS engine into a 1973 to 1976 Corvette Y Body manual transmission chassis, the stock cooling setup can struggle under sustained load and this radiator keeps temperatures in check. Featuring a 26-inch wide core and dual electric fans, it maintains stable airflow across the entire surface even in stop and go traffic or spirited driving. Mounting points match factory frame brackets and plug and play connectors let you install the unit without cutting or splicing while optimized flow paths direct coolant evenly to prevent hot spots. All aluminum construction resists corrosion and transfers heat rapidly so you can rely on consistent performance whether you are cruising or pushing the car on the track.
Engineered 26 inch Core Maximizes Cooling Surface
The 26 inch wide core design expands the contact area between coolant and outside air, enabling rapid heat rejection even under heavy engine loads. Precision welding ensures each tube and fin maintains a consistent flow path, eliminating localized hot spots that can arise during spirited driving. Optimized fin density and spacing strike a balance between airflow resistance and surface area, preserving radiator efficiency without adding undue weight. By directing coolant evenly across the entire core, this radiator stabilizes engine temperatures in stop-and-go traffic or sustained high speed runs. Installation into the Y-Body chassis is seamless, as the core dimensions align with existing frame brackets and mounting points.
Dual Performance Fans Deliver Airflow at Idle
Two high-output electric fans are pre-installed to provide consistent airflow when vehicle speed is insufficient for natural cooling. Their placement covers the full 26 inch core width, preventing heat soak during extended idling or track sessions. Fans activate automatically via temperature-sensing wiring and plug-and-play connectors, eliminating the need for custom wiring or splicing. This approach not only maintains ideal engine operating temperatures but also reduces radiator lag during sudden surges in load. With factory-aligned mounts, the fans integrate neatly behind the core for a clean engine bay presentation.
All Aluminum Assembly Combines Strength and Efficiency
Constructed entirely from premium aluminum, the radiator delivers exceptional thermal conductivity while remaining lightweight. Aluminum's inherent resistance to corrosion limits internal pitting and preserves coolant flow over many heat cycles. Precision TIG welding at every joint forms durable seals that withstand high coolant pressure without leaking. The alloy structure also dampens vibration and endures chassis stress, contributing to a robust cooling solution suited for both street driving and track use. Overall, this component integrates structural integrity with rapid heat transfer for reliable performance.
Coating Selections Balance Protection and Appearance
Choose between a natural finish that maximizes radiant heat transfer or a black epoxy coating that adds an extra barrier against moisture and road salt. Each coating is applied in-house to ensure uniform thickness and adhesion, preventing flaking or uneven coverage. The bare aluminum option highlights the metal’s bright texture, while the epoxy finish complements darker engine bay components for a factory-style look. Both finishes resist chemical exposure and temperature cycling, safeguarding the radiator’s lifespan in diverse conditions. This flexibility allows builders to match aesthetics without compromising thermal performance.
