Manual Transmission Radiator with Fan for LS/LT Swaps in 1958 Chevy B-Body (Impala/Bel Air/Delray)
Swapping an LS or LT powerplant into a 1958 Impala, Bel Air or Delray with a manual gearbox raises coolant demands and this 1973-1974 Nova Radiator (Manual Trans) with Fan tackles heat at its source. Constructed from 100 percent TIG welded aluminum, its dense core uses fine fins to move heat away from both engine and transmission fluid, keeping temps stable during spirited runs or city traffic. Because it bolts onto original frame tabs and uses factory cooling line ports, installation avoids custom brackets and maintains a neat engine bay layout. The integrated fan ensures adequate airflow at idle and low speed without the need for additional wiring.
Precision TIG Welding for Unmatched Structural Integrity
The radiator employs 100 percent TIG welding to fuse its aluminum tanks and core into a single robust assembly. Uniform bead formation reduces stress risers and resists cracking under engine vibration and chassis flex. This welding method ensures each joint is leak proof and has consistent wall thickness, guarding against coolant seepage. With reinforced seams, the structure endures thermal cycles without fatigue, providing reliable performance on both highway cruises and spirited driving. The result is a lightweight unit that does not compromise on strength or longevity.
Aluminum Core with Dense Fin Array for Rapid Cooling
A high grade aluminum core delivers exceptional thermal conductivity for efficient heat transfer away from both engine coolant and manual transmission fluid. Close fin spacing increases the surface area in contact with airflow, accelerating heat rejection even at low vehicle speeds. This design prevents hotspots that can strain gaskets or degrade fluid viscosity, maintaining stable temperatures during stop and go traffic. By using quality aluminum, the core also resists corrosion and maintains performance over many seasons. Drivers will note consistent gauge readings under varied driving conditions.
Flawless Direct Fit Installation on 1958 Chevy B Body
This radiator bolts directly to original frame tabs on 1958 Chevy Impala, Bel Air and Delray models with manual boxes, eliminating the need for custom brackets. Factory cooling line ports align without modification, which preserves the classic engine bay layout. The precise fit reduces installation time and ensures proper hose routing, minimizing the chance of leaks or undue strain on connections. Installers enjoy a straightforward process that maintains all factory mounting points and prevents interference with adjacent components. As a result, the build retains a neat appearance and solid reliability.
Classic Finish and Epoxy Coating for Lasting Protection
Owners can select a natural bare aluminum appearance to highlight period correct styling or choose a black epoxy coat for extra corrosion resistance. The untreated metal finish resists pitting and allows easy inspection of weld seams and surfaces. In harsher environments, the epoxy barrier guards against moisture, salt and road debris, keeping coolant passages clear and free from rust. Both finishes contribute to long term core integrity and simplify routine maintenance. This flexibility lets builders balance visual appeal with year round durability.
