LS and LT Engine Swap Radiator with Auto Trans Fans for 1959-1964 Chevy Impala
Swapping an LS or LT powerplant into a 1959-1964 Impala often creates routing conflicts for engine and transmission cooling lines, and this radiator solves that by consolidating both systems into a single assembly. It drops into the factory support brackets and uses the original transmission cooler ports to keep hoses tidy and leak points to a minimum while the fully TIG welded aluminum core and tanks resist corrosion and speed heat rejection. With dual electric fans that engage only when coolant temps climb, the assembly maintains steady airflow at idle without taxing your charging system and prevents hot spots under sustained load, all without cluttering the engine bay whether you're crawling through traffic or pushing the pace on back roads.
Precision TIG Welding for Leak Free Reliability
The radiator core and tanks are joined by full TIG welding, producing uniform beads and eliminating the stress points found in bolt-together assemblies. By fusing high-quality aluminum at a molecular level, the heat exchanger achieves exceptional leak resistance under high pressure and temperature cycling. This seamless construction also removes the need for sealants or gaskets that can degrade over time, so coolant passages remain fully sealed through countless heat-up and cool-down cycles. The monolithic design reduces mass while increasing structural rigidity, contributing to improved front-end balance and chassis response. Crafted entirely in the USA, the welded joints uphold consistent thermal conductivity across the fin pack, ensuring rapid heat rejection for LS and LT engine conversions.
Dual Electric Fans Deliver Targeted Airflow Control
A matched pair of high-capacity fans is mounted in a custom shroud to pull air uniformly through the entire radiator face. At idle and in slow-moving traffic, both units engage automatically when coolant temperature climbs above the preset limit, preventing heat pockets that can cause hot spots under load. Once vehicle speed generates adequate ram air, the fans deactivate to reduce electrical draw and minimize acoustic signature. By reusing factory connectors and mounting points, the assembly integrates seamlessly with the existing wiring harness, avoiding extra relays or complex modifications. The result is consistent cooling performance whether navigating city streets or pressing the pace on open highways.
High-Grade Aluminum Core with Custom Finish Options
Constructed from premium aluminum, the radiator combines low weight with superior thermal efficiency and innate corrosion resistance. Aluminum's high conductivity allows coolant to shed heat rapidly as it passes through the fin pack, maintaining stable operating temperatures beneath sustained power delivery. Builders can choose a classic bare metal finish to maximize heat transfer and showcase a factory-style appearance, or opt for a durable black epoxy coat that resists road salt, moisture, and debris without compromising thermal performance. Both treatments protect header areas and weld seams from oxidation, ensuring the assembly retains its structural integrity and visual appeal over many seasons of driving.
This assembly ensures reliable cooling for your LS or LT swap project. For the same radiator but without fans consider our 1959-1964 Impala Radiator (Automatic Transmission).
