LS and LT Swap Radiator for 1964-1967 A-Body Chevelle and El Camino
Installing an LS or LT into a 1964-1967 Chevelle or El Camino A Body automatic demands precise coolant control and the Chevelle Radiator (Auto Trans) with Fans keeps temperatures in check under heavy load and during slow speed traffic. Constructed around a TIG welded aluminum core, the assembly resists fatigue under constant vibration and heat exposure while two balanced 16 inch fans ensure steady airflow at low vehicle speed. Built to bolt onto factory frame rails with brackets for 4L60E and 4L80E transmissions, it offers direct fitment for a straightforward installation and reliable hose port alignment. Options for bare aluminum or black epoxy finish let you choose corrosion resistance or an open metal appearance without sacrificing heat rejection.
Precise TIG Welded Aluminum Core for Enduring Durability
The radiator core and end tanks are assembled using TIG welding, which yields consistent fusion across high grade aluminum surfaces. This process produces joints free of voids and inclusions, greatly reducing the risk of cracks under repeated thermal cycles and constant vibration from LS and LT engines. The aluminum material combines low weight and high thermal conductivity, enabling rapid heat transfer from coolant to air. Over time this leads to stable engine temperatures even when running at high load or under heavy city traffic. Structural integrity remains intact longer compared to alternative weld methods, making this core a dependable choice for extended use. As a result, maintenance intervals can be extended and downtime is reduced. Built under strict standards in the USA, it meets rigorous quality checks before shipping.
Balanced Dual 16 Inch Fans Maintaining Constant Airflow at Low Speed
Two 16 inch electric fans are preinstalled and precisely balanced to eliminate vibration and ensure uniform airflow across the radiator surface. This arrangement improves heat rejection at idle and during slow traffic when natural airflow through the grille is minimal. By directing fresh air evenly through each fin row, these fans prevent hot spots and reduce the risk of coolant boilover under heavy load conditions. Noise and power draw are optimized to deliver reliable performance without placing undue load on the electrical system. Technicians can count on consistent cooling even during extended idling, such as during engine warm up or in urban driving. The matched fan speeds also contribute to smoother operation and reduced motor wear over time.
Purpose Cut Brackets Ensuring Plug and Play Frame Rail Mounting
The radiator mounting kit includes brackets engineered for direct bolt on installation to factory frame rails of 1964 to 1967 Chevelle and El Camino models. These mounts are purpose cut for compatibility with 4L60E and 4L80E automatic transmissions, aligning hose ports and fan wiring channels without modification. By matching original equipment tolerances, the design eliminates trial and error during swap operations and avoids bending or drilling of frame components. Installers benefit from precise hole locations and correct bracket clearances, delivering a new radiator that sits exactly where the factory unit once did. This approach reduces installation time and supports a clean engine bay layout that maintains proper coolant flow angles and line routing. As a result, coolant connection leaks are minimized and service access remains straightforward.
Classic Bare Aluminum and Black Epoxy Finish Offering Durable Protection
Builders have the choice of an uncoated aluminum finish that highlights the natural surface grain or a black epoxy layer designed to resist corrosion. The classic bare aluminum option allows maximum thermal conductivity, shedding heat quickly for peak engine performance. In contrast, the epoxy coating bonds to the metal surface and seals out moisture, road chemicals, and airborne contaminants without impairing heat transfer. This versatility lets owners match the engine bay aesthetic while ensuring long term durability in harsh environments. Both finishes undergo a strict quality inspection to check for complete coverage and proper adhesion before leaving the factory. The result is a radiator that not only looks refined but also stands up to daily driving and track use alike.
