LS and LT Radiator for 1958 Chevy B-Body Manual Trans with Fan (Impala, Bel Air, Delray)
When dropping an LS or LT powerplant into a 1958 Chevy Impala, Bel Air or Delray fitted with a manual transmission and fan, this radiator is engineered to preserve steady coolant flow and prevent overheating under sustained load. Its full aluminum core features a dense fin and tube arrangement for rapid heat rejection, while the integrated electric fan shroud directs airflow exactly where it is needed most. Installation requires no cutting or welding thanks to precise mounting points that align with original positions on B-body frames, cutting shop time and preserving the chassis. Welded by TIG for uniform bead formation, the tanks and tubes lock out leaks and resist thermal warping through repeated heat cycles, ensuring reliable service during spirited runs or towing.
Precision TIG Welding for Core Durability
The radiator's aluminum tanks and tubes are joined using tungsten inert gas welding techniques that produce uniform bead formation and deep penetration. This process minimizes the risk of coolant leaks by creating a reliable seal across all joints. Resistance to vibration and repeated heat cycling is enhanced by the precise weld profile that remains consistent under strain. The choice of pure aluminum helps maintain a low overall weight while still providing the strength needed to withstand pressure fluctuations. As a result this TIG welding approach supports long service life without compromise.
Efficient Heat Rejection with All Aluminum Core
Featuring an all aluminum core, this radiator uses a high tube density and a dense fin and tube arrangement to maximize surface area for heat transfer. The dense fin and tube arrangement creates channels that promote rapid coolant flow while exposing more metal to incoming air. Aluminum's natural thermal conductivity moves heat away from the engine quickly, preventing temperature spikes under sustained load. Corrosion resistance in the core material also means this radiator maintains peak efficiency over many seasons. Drivers benefit from stable operating temperatures whether towing heavy loads or pushing an LS or LT engine on the open road.
Engineered Fan Shroud for Targeted Cooling
An integrated electric fan shroud is shaped to channel airflow directly through the core, eliminating turbulence that can reduce cooling capacity. This targeted approach ensures that air drawn by the fan makes full contact with the radiator fins rather than escaping around the edges. By focusing airflow in this way the cooling system is able to maintain steady coolant temperatures even during low speed operation or stop and go traffic. The design also simplifies the installation since the shroud lines up with existing fan mounts on the B body frame. Technicians appreciate the precise fit that cuts shop time and preserves factory structural integrity.
Finish Options Offering Corrosion Protection
Builders may choose between a natural aluminum surface finish for classic appeal or a black epoxy coating that adds an extra barrier against moisture and road contaminants. The epoxy option is applied under controlled conditions to achieve uniform coverage without hindering heat transfer through the core. Even the untreated aluminum surface exhibits strong resistance to oxidation and requires minimal upkeep to stay clean and functional. This flexibility allows restorers and custom shops to match the radiator appearance to the surrounding engine bay components. Both finishes deliver reliable corrosion protection that supports lasting performance.
