Radiator for LS and LT Engine Swaps in 1958 Chevy Impala, Bel Air, Delray
When adapting an LS or LT engine into a 1958 Chevy B Body, the 1973-1974 Nova Radiator (Manual Trans) with Fan addresses coolant stability under a variety of driving conditions. Assembled with TIG welded aluminum tanks and a full core, this assembly aligns its inlet and outlet ports precisely to stock mounting points on Impala, Bel Air and Delray frames to maintain original hose routing and pulley clearance. A pair of electric fans mounted directly to the core ensures even airflow at low speeds and idle without bulky shrouds in cramped engine compartments. Installation is fast thanks to factory frame mounts that eliminate custom brackets and preserve engine bay space.
Precision CNC Machined Ports for Seamless Hose Alignment
The radiator's inlet and outlet ports are crafted using CNC machining to match the exact dimensions and positions of the original 1958 Chevy B Body hose paths. By replicating factory routing, installers can reuse stock hoses and fittings without modifying bracketry or adjusting pulley clearance. This precise fit reduces potential for kinks or leaks and ensures an unobstructed coolant flow path through LS and LT engine accessories in tight compartments. Overall, the direct alignment cuts installation time and maintains the integrity of the original belt drive layout.
TIG Welded Aluminum Tank and Core for Robust Cooling Efficiency
Each tank and the core are joined with tungsten inert gas welding to create continuous, pore free seams that stand up to vibration and repeated thermal cycles. Aluminum's natural conductivity works in concert with the weld geometry to spread heat evenly across the core, boosting rejection rates when the engine is under load. The material choice also resists corrosion and deformation, keeping the assembly rigid even under high coolant pressure. This construction method supports consistent performance whether cruising through traffic or pushing on the track.
Integrated Dual Electric Fans Maintain Steady Coolant Temperatures
Two high capacity electric fans are mounted directly to the radiator core to draw air across every fin at low speeds and idle. Temperature sensors activate the fans precisely when coolant temps rise above preset thresholds, preventing hot spots during stop and go driving or spirited acceleration. Without a bulky shroud, this setup maximizes usable space in a crowded engine bay and avoids interference with LS and LT accessory drive components. Wiring taps into the existing harness routes for a clean installation and reliable power delivery.
Coating Options Enhance Durability and Style
Two finish choices allow builders to balance appearance with corrosion resistance. Natural bare aluminum provides a classic look that develops a subtle patina over time while maintaining excellent thermal transfer characteristics. Conversely, a black epoxy coating seals the surface against moisture and salt, delivering a sleek appearance that complements darker engine bays. Both options are applied in the USA to ensure consistent coverage and surface adhesion for long term durability.
