Radiator for LS Swap 1973-1976 Chevy Corvette Manual Trans Y-Body with Dual Fans
Upgrading the cooling system on a 1973-1976 Corvette Y Body LS swap with a manual transmission often reveals the limits of the stock radiator, especially during spirited drives or in heavy traffic. The 26 inch wide core radiator with dual electric fans expands coolant flow area for even heat rejection and keeps temperatures under control when airflow alone is not enough. Installation uses factory frame brackets and plug and play connectors to maintain the original structure without modification. Constructed from corrosion resistant aluminum in the USA, this radiator delivers consistent performance whether you are cruising highways or tackling laps on the track.
Precision Core Design for Consistent Heat Rejection
The 26 inch wide core expands the contact area between coolant and airflow, allowing engine heat to dissipate evenly across every tube and fin stack. By optimizing tube spacing and fin density, this radiator prevents hotspots that can form during spirited driving or in slow moving traffic. The generous core width also aligns perfectly with factory frame brackets, ensuring a precise fit that keeps coolant flow balanced and maintains original chassis geometry. This design supports uniform temperature control whether cruising highways or managing stop and go city conditions.
Integrated Dual Fan System for Reliable Cooling
Two preinstalled electric fans span the full width of the radiator to deliver consistent airflow at idle and low speeds. Temperature sensors activate the fans automatically through plug and play connectors, eliminating any need for custom wiring or splicing. This integrated approach reduces the time lag between rising coolant temperature and fan engagement, safeguarding engine operating range under heavy load or track sessions. Factory aligned mounts keep the fans snug against the core, blending functionality with a clean engine bay appearance.
Rugged Aluminum Construction with Expert Welding
Crafted entirely from high quality aluminum, the radiator core and tanks offer exceptional thermal conductivity while keeping overall mass to a minimum. Aluminum's natural resistance to corrosion helps prevent pitting and blockages, even after repeated heating cycles and exposure to moisture. Every joint is joined by precision TIG welding to form leak proof seals capable of withstanding elevated coolant pressure. The inherent stiffness of the alloy also provides damping against engine vibration, making this assembly durable for both street use and track competition.
Custom Finish Options for Protection and Style
Choose a bare aluminum finish to maximize radiant heat dissipation or opt for a black epoxy coat for added resistance against road chemicals and moisture. Both treatments are applied at a controlled thickness to prevent flaking and ensure long lasting adhesion under thermal cycling. The natural aluminum surface showcases a bright metallic look, while the black finish integrates with darker engine bay components for a factory inspired appearance. Each option guards against environmental exposure, so you can maintain both performance and visual appeal in varied conditions.
