LS and LT Manual Transmission Radiator with Fan for 1958 Chevy B-Body Impala/Bel Air/Delray
Starting a manual transmission LS or LT swap in your 1973-1974 Nova demands reliable cooling and this direct fit radiator with integrated electric fan answers that challenge while matching the factory frame rail locations for a straightforward installation.
Its all aluminum core combined with precision TIG welded tanks ensures rapid heat dissipation and resists warping or leaks through repeated heat cycles even under heavy duty conditions.
Mounting hardware aligns with original Nova chassis points so there is no cutting or welding required and airflow is funneled by the shroud directly through the core to protect factory structure and reduce installation time.
Precision TIG Welding for Tank and Tube Integrity
Every joint on the radiator is assembled using TIG welding, a process that delivers a consistent bead and deep fusion at each connection between tank and core. This technique produces a joint so uniform that it virtually eliminates micro gaps where coolant could escape under pressure. The fusion strength also means the assembly resists fatigue from vibration and heat cycling, ensuring that even under the rigors of LS and LT engine loads the structure remains rock solid. Technicians recognize that this level of weld precision translates directly to long service intervals without the need for frequent inspections or repairs.
Advanced Aluminum Alloy Core for Rapid Heat Rejection
At the heart of the radiator lies a dense array of aluminum alloy tubes and fins chosen for their excellent thermal conductivity and low mass. As coolant circulates, heat is transferred instantly into the metal matrix and then expelled to passing air, preventing temperature spikes during heavy acceleration or towing. The fin density is optimized to strike the right balance between flow resistance and surface area, so airflow remains strong even at low fan speeds. This engineered core design delivers consistent coolant temperatures whether cruising on the highway or navigating urban traffic.
Tailored Coating Choices Enhancing Corrosion Resistance
Builders can select from two factory finishes - the classic bare aluminum surface or a sleek black epoxy coat - both applied under strict quality controls. The bare surface leverages aluminum's inherent resistance to oxidation, while the epoxy layer adds an extra barrier against moisture and road debris without impeding heat transfer. Each finish undergoes rigorous adhesion testing to guarantee that chips and scratches do not expose bare metal to corrosion. As a result, the radiator maintains peak performance and appearance season after season, preserving the value of the installation.
Plug and Play Fit with 1958 Chevy B-Body Frame Rails
This radiator is engineered to align exactly with the original frame rail mounting points on 1958 Impala, Bel Air, and Delray chassis, so no modification or cutting is required. The mounting brackets and shroud support engage factory holes, preserving the integrity of the B-Body structure. In addition, the integrated electric fan shroud directs airflow straight through the core rather than around its edges, delivering maximum cooling even at idle or in slow city driving. This direct fit approach slashes installation time and ensures a clean, professional outcome on every LS or LT swap.
Built for consistent cooling under load, this option ensures lasting peace of mind. To access the same radiator but with fans, consider our 1958 Impala Radiator (Manual Transmission) with Fans.
