LS and LT Radiator for 1958 Chevy B-Body (Impala/Bel Air/Delray)
For LS and LT engine swaps into a 1958 Chevy B Body, the 1973 to 1974 Nova Radiator (Manual Trans) with Fan answers the challenge of managing coolant temperature under sustained load. Installation is straightforward thanks to factory alignment to original mounting points on Impala, Bel Air and Delray frames, eliminating the need for custom brackets or frame modifications. Its precision CNC inlet and outlet ports follow original hose paths to avoid custom plumbing and preserve belt alignment in tight engine bays. Featuring TIG welded aluminum tanks and a full core assembly, dual fans draw air evenly across each fin row to maintain steady coolant temperatures at idle or during spirited runs.
Precision CNC Machined Ports for Direct Hose Alignment
The 1973 to 1974 Nova radiator is engineered with precision CNC machined inlet and outlet ports that align exactly with factory hose paths on 1958 Chevy B-Body frames. This accuracy eliminates the need for custom plumbing or altered frame components, preserving original belt and pulley clearances for manual transmission installations. By following the stock routing, these ports ensure that coolant flow is smooth and unrestricted, reducing the risk of kinks or fitting leaks. Installers benefit from the straight-forward fit, which cuts setup time and avoids clearance issues with LS and LT engine accessories in tight engine bays.
Precision TIG Welded Aluminum Tank and Core Assembly
Both tanks and the core are assembled using TIG welded joins, a method that produces uniform bead profiles and eliminates porosity at each seam. High quality aluminum offers excellent thermal conductivity to transfer heat from coolant to radiator fins, while its inherent strength resists deformation under engine vibration and thermal cycling. The weld geometry promotes even coolant distribution across internal passages, reducing stress points that can lead to cracking under repeated temperature changes. This durable construction maintains structural integrity and supports fast heat rejection during extended street driving or spirited track sessions.
Integrated Dual Fan System for Steady Cooling Performance
Two high-capacity electric fans are mounted directly to the radiator core, drawing air evenly across every fin row at low engine speeds and at idle. Temperature-controlled activation ensures that the fans run only when needed, maintaining a steady coolant temperature during stop and go traffic and spirited runs. Without bulky fan shrouds, the assembly preserves valuable space in a confined engine bay, making it ideal for LS and LT engine swaps. Fan wiring follows existing harness routes to simplify installation, delivering reliable performance and optimal airflow under all driving conditions.
Trust this radiator for steady coolant management in your LS and LT swap. For the same radiator but without fans consider our 1958 Impala Radiator (Manual Transmission).
