LS and LT Swap Radiator with Fans for 1959-1964 Chevy Impala Auto Transmission
If you are swapping an LS or LT engine into a 1959-1964 Chevy Impala B-Body with automatic transmission this radiator meets the critical challenge of keeping coolant temperatures in check during both spirited runs and daily commutes. It features a full aluminum core alongside a pair of electric fans that maintain steady airflow at idle or under heavy load while dropping directly into factory mounting points with integrated transmission cooler ports for a clean installation without cutting or welding. Built with precision TIG welded tanks and an optional black epoxy finish this unit resists corrosion in a classic engine bay and delivers dependable cooling performance whether you are navigating stop and go traffic or testing highway speeds.
Precision TIG Welded Aluminum Assembly
Crafted entirely from high quality aluminum, this radiator relies on precision TIG welding to fuse its end tanks and core into a unified structure. The TIG process creates smooth, leak-resistant joints that withstand the vibration and pressure cycles common in LS and LT engine swaps. Aluminum's rapid thermal conductivity promotes swift heat transfer from coolant to fins, delivering faster cooling response during hard acceleration or extended highway runs. Being fully welded also reduces potential fatigue points, resulting in a lightweight assembly that retains strength and reliability season after season.
Optimized Dual Electric Fan Cooling Performance
A matched pair of electric fans is mounted within a molded shroud that channels air uniformly through the full fin pack. At idle or in heavy traffic, these fans maintain consistent airflow and eliminate hotspots that could lead to sudden temperature increases. The high capacity blades are designed to pull maximum volume without overloading the charging system, ensuring efficient operation under load. During highway cruising or spirited driving, the fans engage only when needed, balancing cooling efficiency with minimal noise and power draw.
Integrated Transmission Cooler Ports for a Clean Engine Bay
The radiator includes built-in ports for automatic transmission fluid cooling that connect directly to factory lines without additional adapters. This integration simplifies plumbing and reduces fitting count, lowering the risk of leaks and ensuring a neat installation in your 1959 to 1964 Impala engine bay. It bolts into the original mounts and uses stock hardware so no cutting or fabrication work is necessary. The tidy layout preserves engine bay aesthetics and supports quick service access to both coolant and transmission circuits.
Classic Aluminum or Black Epoxy Finish for Lasting Protection
Choose from a polished bare aluminum surface or a durable black epoxy coating to match your restoration or custom build style. The bare finish can be easily buffed to restore shine and maintains excellent heat transfer properties. The epoxy option forms a protective barrier against moisture, road debris and corrosion while retaining thermal performance. Both treatments safeguard the core and end tanks against environmental damage, ensuring reliable cooling capacity and a showroom quality appearance for years to come.
