LS and LT Swap Radiator with Fan for 1958 Chevy B-Body (Impala/BelAir/Delray) Manual Trans
Swapping an LS or LT V8 into a 1973-1974 Nova with a manual transmission can run hot under sustained load and this radiator with integrated fan is designed to keep coolant temperatures in check. Its precision TIG welded tanks and dense fin arrangement ensure durability and rapid heat rejection while resisting leaks and warping through repeated heat cycles. Featuring an all aluminum core and direct‐fit mounts that line up with original points on the B‐body frame, installation requires no cutting or welding on the chassis. Airflow is optimized by the integrated electric fan shroud which directs cooling air squarely through the core even in stop and go traffic, reducing shop time and preserving factory structure.
Precision TIG Welding for Core Integrity
TIG welding unites aluminum tanks and tubes with uniform bead formation and deep fusion at each joint. This method creates a seamless bond that significantly reduces the risk of coolant leaks over time. The precise weld profile also resists fatigue from vibration and cycles of heat expansion. Using this technique on every junction ensures the core maintains structural integrity under high pressure. As a result, the system delivers reliable service through rigorous mileage and towing demands.
High-Grade Aluminum Core Enhancing Thermal Efficiency
The radiator core is constructed from high-grade aluminum alloy known for its superior conductivity and light weight. A dense arrangement of fins and tubes maximizes the surface area exposed to airflow, promoting rapid heat transfer away from the coolant. Aluminum's natural resistance to corrosion preserves that efficiency season after season. By combining low mass with robust heat rejection, the design prevents temperature spikes under sustained engine load. Owners benefit from steady coolant temperatures whether driving fast or hauling payloads.
Engineered Fan Shroud Guaranteeing Directed Airflow
The integrated fan shroud channels air pulled by the electric fan directly through the core rather than around its edges. This targeted flow eliminates turbulence and ensures the fins receive a consistent blast of cooling air. Even in slow speed or stop and go traffic conditions, the system sustains optimal coolant temperatures. Mount points align precisely with the original B body frame locations, simplifying the fit process. Technicians save time while preserving the chassis structure thanks to this direct fit design.
Finish Selections for Tailored Corrosion Protection
Two finish options allow a balance between aesthetic preference and environmental defense. The classic bare aluminum look highlights the core's engineering while still offering natural resistance to oxidation. The black epoxy coating is applied under strict quality controls for uniform adhesion and adds a durable barrier against moisture and debris. Both options maintain core performance without hindering heat transfer. Builders can choose the style that best matches their engine bay while relying on lasting protection.
