1973-1976 Chevy Corvette Y-Body Radiator for LS Engine Swap Manual Trans
When installing an LS powerplant into a 1973–1976 Corvette Y-Body with a manual transmission, maintaining stable coolant temperatures becomes critical, and this 26 inch wide core radiator steps in to ensure consistent heat rejection. Featuring plug and play connectors and factory frame mounts, it installs without altering the original chassis geometry, positioning the core precisely in the Y-Body radiator support. A corrosion resistant aluminum build is TIG welded for durable seals and paired with dual electric fans that activate automatically through temperature sensors to keep engine heat in check at idle and under load. Built in the USA, this assembly preserves factory fitment and supports consistent temperature control during spirited runs or in heavy traffic.
Precision Core Layout for Uniform Cooling
The 26 inch wide core maximizes the interface area between coolant and incoming airflow to reject heat evenly across the entire radiator surface. Optimized tube spacing and fin pattern reduce localized hot spots that can appear when driving aggressively or creeping in traffic. By matching factory bracket geometry the core sits precisely in the original support structure to keep chassis alignment intact. This uniform layout helps maintain stable engine temperatures whether you are on highway cruises or tackling spirited road work.
Seamless Dual Fan Integration
Two electric fans are preinstalled to span the full width of the radiator and deliver consistent airflow at idle and low road speeds. Sensors monitor coolant temperature and trigger fan operation through plug and play connectors, removing the need for custom wiring or delay. The instant response helps keep the engine in its ideal range under heavy load or on track sections. Factory style mounts ensure the fans sit close to the core for maximum draw and a tidy engine bay look.
Durable Aluminum Construction with TIG Welding
Constructed from high quality aluminum, both core and end tanks offer excellent thermal conductivity while keeping overall weight low. The alloy's natural resistance to corrosion prevents internal pitting and blockages after repeated temperature cycles and exposure to moisture. Precision TIG welds form leak proof joints that withstand elevated coolant pressure and engine vibration. This robust assembly is built in the USA to deliver lasting performance on street runs or track sessions.
Custom Finish Choices for Protection and Style
Choose the bare aluminum option to maximize radiant heat rejection or select the black epoxy coating for added defense against road chemicals and moisture. Each finish is applied to a controlled thickness that resists flaking and maintains adhesion through thermal cycling. The natural aluminum surface reveals a bright metallic sheen, while the black finish blends with darker components for a unified engine bay. Both options guard against environmental exposure to preserve performance and appearance.
