Radiator for LS and LT Engine Swaps in 1959-1964 Chevy Impala
Fitting a modern LS or LT engine behind the automatic transmission in a 1959-1964 Impala often leads to clearance conflicts and cooling shortfalls within the stock core support structure. The 1959-1964 Impala Radiator (Auto Trans) uses a full aluminum tube and fin core combined with precision TIG welded tanks to conduct heat away rapidly while resisting vibration, corrosion, and thermal cycling. By matching original inlet and outlet locations and aligning precisely with factory mounting points it secures without adapters or custom brackets, reducing installation time and avoiding leaks. This direct fit solution maintains consistent coolant flow under varied driving conditions, protects critical engine and transmission components, and preserves the Impala B-Body frame geometry for project completion.
Precision TIG Welded Aluminum Tanks
The radiator's tanks are assembled using a TIG welding process that fuses high quality aluminum with exceptional seam integrity. By employing a tungsten electrode and an inert gas shield, each joint is formed with deep penetration and minimal porosity, greatly reducing the chance of coolant leaks under constant vibration. This method yields clean weld beads that require little finishing, maintaining unobstructed coolant paths and strong tank walls. As a result, the radiator endures repeated thermal cycles and engine load without cracking or fatigue, making it a reliable choice for both daily driving and towing applications.
Engineered Tube and Fin Core for Efficient Heat Rejection
At the heart of the unit lies a full aluminum tube and fin core that balances rapid heat transfer with low mass. Thin wall tubes guide hot coolant into a dense network of fins where oncoming air strips heat efficiently, preventing temperature spikes even under high output. The carefully calibrated fin spacing ensures coolant velocity remains optimal without overtaxing the water pump, preserving consistent flow rates. In addition to improved thermal management, the lightweight core contributes to balanced front end weight and sharper steering response.
Classic Bare Aluminum or Durable Black Epoxy Finish
Builders can select from a bare aluminum finish that highlights precise weld lines or a black epoxy coating that enhances corrosion resistance. The bare version offers an authentic look and accepts polish for a custom shine, while the epoxy variant is cured in an oven to ensure uniform adhesion and resistance to chipping. Both finishes are engineered to preserve core performance so styling choices do not compromise cooling capacity. This flexibility lets owners tailor the engine bay appearance while protecting the radiator against road debris and moisture.
Direct Fit Installation on 1959 to 1964 Impala B Body
Designed specifically for 1959 through 1964 Impala B Body frames, this radiator aligns with factory support points and accepts original transmission cooler lines without any adapters. The plug and play fit eliminates the need for custom brackets or extra tubing, cutting installation time and reducing the risk of damage to the core support. By matching inlet and outlet locations exactly, it preserves chassis geometry and maintains resale value by avoiding frame alteration. Installers can focus on wiring and plumbing instead of metalwork, achieving a seamless swap.
