LS and LT Radiator Upgrade for 1958 Chevy Impala/Bel Air/Delray B-Body
When swapping an LS or LT mill into a 1958 Chevy Impala, Bel Air or Delray B Body chassis, the 1973-1974 Nova Radiator (Manual Trans) with Fan resolves the overheating and fitment issues that plague custom conversions. Featuring a full TIG welded aluminum core and factory aligned mounts, this radiator drops into the stock frame rails without cutting or custom brackets. Its pair of fans bolted directly to the core delivers steady airflow during city driving or spirited runs to maintain stable coolant temperatures. Installation remains straightforward thanks to precision supports that align with the original mounting points and hood latch crossmember clearance.
Precision TIG Welding for Core Integrity
By using tungsten inert gas welding to fuse each tank and core assembly, this radiator achieves seams that are free of porosity and weak spots. This method minimizes heat distortion and preserves the metal's grain structure, enabling the core to flex with engine vibration without developing cracks. Every joint undergoes rigorous pressure and visual testing to confirm leak resistance under repeated heating and cooling cycles. The result is a radiator that maintains structural integrity and dependable coolant flow even during demanding driving conditions.
Dual Fan Airflow Management for Consistent Cooling
Two high-performance fans are bolted directly to the face of the core to ensure uniform air delivery across the entire fin pack. By eliminating remote shrouds and ducting, this arrangement reduces noise and vibration while simplifying installation. The fans activate in sync to prevent local hot spots during both steady highway cruising and stop and go traffic. This balanced airflow strategy safeguards head gaskets and hoses by keeping coolant temperatures within optimal range.
High Grade Aluminum Construction for Lightweight Durability
The core and tanks are crafted from high grade aluminum, offering superior thermal conductivity and corrosion resistance without adding excessive weight. This lightweight profile helps preserve original chassis balance and steering feel while rejecting heat quickly during spirited runs. Aluminum's natural resistance to rust extends service life and reduces maintenance, so coolant passages stay clear of scale and deposits. The combination of strength and low mass supports a long service interval in street or track applications.
Bare and Epoxy Coatings for Corrosion Defense
Two finish options let you tailor durability and appearance to your driving environment. The uncoated aluminum version develops a unique patina over time, offering an authentic look that integrates with any engine bay. Alternatively, the black epoxy finish is baked on to bond tightly with the metal surface, creating a barrier against road salt, moisture and chemicals. Each radiator is inspected for uniform coverage to ensure long term corrosion resistance and consistent heat rejection performance.
