Radiator with Fans for 1959-1964 Chevy Impala LS and LT Engine Swaps
When swapping an LS or LT powertrain into a 1959 through 1964 Chevy Impala B Body, consolidating engine and transmission cooling in a single unit can eliminate plumbing headaches. This radiator installs directly into factory support brackets, uses stock transmission cooler lines for a neat engine bay layout, and features TIG welded aluminum construction that resists corrosion, speeds heat rejection, and cuts weight for better front end balance. A matched pair of electric fans engages only when coolant temperature climbs past the preset limit, ensuring steady airflow at idle or during spirited runs without drawing excessive current and preventing hot spots.
Precision TIG Welding for Consistent Thermal Transfer
The radiator's core and end tanks are fabricated entirely from high-grade aluminum and joined by precision TIG welding. This process produces exceptionally smooth, uniform weld beads that resist leaks and eliminate stress zones common with bolt-together assemblies. Aluminum's natural ability to conduct heat rapidly ensures that coolant circulation across the fin pack translates directly into faster temperature reduction under sustained load or spirited driving. A fully welded structure also cuts overall weight compared to multi-piece designs, contributing to better balance at the front of the chassis. Assembled in the USA, this seamless build delivers both strength and reliability for LS and LT engine conversions.
Efficient Dual Electric Fan Array Maintaining Engine Temperature
A matched pair of high-capacity electric fans is mounted in a custom shroud to draw air evenly through the entire height of the radiator. At idle or in slow-moving traffic, both fans engage automatically when coolant temperature rises above a preset threshold, preventing heat pockets that can lead to coolant boil under hard use. When airflow at speed is sufficient, the fans remain off to minimize alternator draw and reduce acoustic output. Wiring and mounting hardware reuse factory locations and stock connectors, avoiding extra relays or altered harnesses. This arrangement preserves a tidy engine bay while ensuring consistent air delivery across the fin pack.
Seamless Integration of Transmission Cooling Ports
Integrated transmission cooler ports accept factory automatic transmission lines without the need for adapters or aftermarket fittings. Ports are located for direct connection to the original bellhousing adapter, which eliminates the risk of added leak points and maintains a clean routing path. When installing, the radiator slides into existing support brackets and secures using stock fasteners, so no cutting, welding, or bracket modification is required. This design keeps both coolant and transmission circuits easily accessible for service and inspections, ensuring long-term reliability. Retaining the stock plumbing layout also contributes to a polished, uncluttered engine bay appearance.
Protective Bare Aluminum or Epoxy Finish Options
Two surface treatments allow customization to suit restoration themes or custom builds. The classic bare aluminum finish can be left natural or buffed to a bright mirror shine, preserving the metal's maximum heat-transfer rate and showcasing a factory-style aesthetic. Alternatively, a durable black epoxy coating provides a corrosion-resistant barrier that stands up to road salts, moisture, and debris without hindering thermal performance. Both finishes seal the end tanks and header areas against environmental exposure, helping prevent pitting and oxidation over time. The result is a long-lasting radiator that delivers reliable cooling and a clean look beneath the hood.
