LS and LT Radiator with Fans for 1963-1966 Chevy/GMC C/K Series Trucks Manual Transmission

Swapping an LS or LT engine into a 1963-1966 C/K Series truck quickly reveals the limits of the original cooling system, and this 1963-1966 GM Truck Radiator (Manual Trans) with Fans was built to keep operating temperatures in check from idle to highway speeds. It features a 100 percent TIG welded aluminum core that sheds heat rapidly while withstanding vibration and corrosion. Designed for C10, C15, K10 and K15 models with manual transmissions, the radiator drops into factory mounts and aligns with the original shroud and hose outlets. To aid airflow in traffic and at speed two low draw electric fans engage only when needed so alternator capacity stays available for accessories.

Precision TIG Welding for Durable Aluminum Core

This radiator core and its tanks are assembled using TIG welding, a method that produces consistent weld beads and minimizes metal distortion. The clean, precise welds ensure leak-free performance under engine vibration and road stress. Constructed entirely from high quality aluminum, the core sheds heat rapidly, keeping LS or LT engine temperatures in check. Built in the USA to exacting standards, it delivers reliable, long lasting operation in 1963–1966 C and K series trucks.

Dual Electric Fans for Steady Cooling at Any Speed

Equipped with two electric fans, this radiator maintains airflow through the full 28.25 inch core whether you're stopped in traffic or driving on an open road. At low speeds the fans draw cool air evenly to prevent heat soak during heavy load conditions. As road speed increases, the system only runs the fans when needed, preserving alternator output for accessories. This balanced design ensures LS and LT swaps remain within optimal temperature ranges under all driving scenarios.

Bare Aluminum and Black Epoxy Finish Options

Choose the uncoated aluminum version for maximum radiant cooling or select a black epoxy coat for enhanced resistance to moisture and road chemicals. Both finishes maintain structural integrity and guard against corrosion, ensuring consistent performance over time. The epoxy choice also offers a refined aesthetic that complements restored or customized trucks, while the bare finish retains a period-correct look without sacrificing heat rejection.

Engineered for reliable cooling with a precise fit and proven durability; for the same radiator but without fans see our 1963-1966 GM Truck Radiator Manual Transmission.
