LS and LT Radiator for 1958 Chevy Impala/Bel Air/Delray B-Body
Installing the 1973 to 1974 Nova Radiator (Manual Trans) with Fan in your 1958 Chevy Impala, Bel Air or Delray B Body swap addresses the unique cooling demands of coupling an LS or LT powerplant to a manual transmission. By combining a fully TIG welded aluminum core with factory aligned mounts the design fits the B Body chassis without modifications or custom brackets. A single fan bolted to the core ensures steady airflow through the fins under city traffic or spirited runs where heat rejection is critical. With corrosion resistant tubing and a lightweight profile this radiator maintains stable coolant temperatures and protects engine components throughout every mile.
Precision TIG Welding for Robust Core Integrity
The radiator's tanks and core are joined using precision tungsten inert gas welding, creating uniform seams that resist cracking under repeated heating and cooling cycles. This method produces a clean bond between each high quality aluminum tube and plate, eliminating weak points where leaks often develop. Because the welds are free of porosity and overlap, the assembly holds its shape even when subjected to vibration and thermal stress from an LS or LT powerplant. Each joint undergoes visual and pressure inspection to confirm toughness and ensure dependable heat rejection on every drive.
Dual Fan Configuration for Even Airflow Distribution
With two fans mounted directly to the face of the core, this radiator pushes air across the full surface area to prevent localized hot spots in stop and go traffic or under sustained load. The synchronized operation of the fans maintains stable coolant temperatures, reducing strain on head gaskets and hoses when the engine is working hardest. By delivering consistent airflow whether you are idling at a light or hammering through a sweep of corners, the system maximizes thermal efficiency and protects internal engine components. This balanced approach also helps preserve peak power output by avoiding excessive heat buildup.
Coating Choices Deliver Protection and Visual Appeal
Choose between a bare aluminum finish that showcases the metal's natural texture and allows a custom patina to form over time or a black epoxy coating that provides an added barrier against moisture and road chemicals. The epoxy is applied in controlled conditions and baked to ensure full coverage and adhesion, preventing corrosion in humid or salty environments. The untreated option highlights the grain structure of the alloy and can be polished or left to age for a vintage look. Both finishes undergo a final quality check to confirm even application and lasting performance.
Factory Aligned Fitment for 1958 Chevy B Body Frames
Designed specifically for the 1958 Chevy Impala, Bel Air, and Delray B Body chassis, this radiator drops into place using the original mounting locations without cutting or custom brackets. Built in supports for the automatic transmission version guarantee correct clearance from the fan shroud and hood latch crossmember, eliminating fitment headaches. This precise alignment speeds installation and prevents vibration or contact with surrounding components. By matching factory geometry, the radiator ensures proper coolant routing and reliable performance from the very first engine start.
