Precision Cooling for LS LT Conversions on 1963-1966 C/K-Series Trucks

Premium aluminum tanks and core deliver rapid heat rejection and lasting durability for LS and LT swaps in 1963-1966 C/K-Series trucks, while dual fans maintain steady engine temperatures in traffic and under load. Crafted in the USA with 100% TIG-welded aluminum construction and an integrated transmission cooler, this radiator resists corrosion while providing lightweight precision fitment for C10, C15, K10 and K15 models equipped with automatic transmissions.

Radiator for LS and LT Swaps in 1963-1966 C/K-Series Chevy GMC Trucks

Installing an LS or LT engine into a 1963-1966 C/K-Series Chevy or GMC truck demands reliable cooling, and the 1963-1966 GM Truck Radiator (Auto Trans) with Fans is built to deliver consistent temperature control in city traffic and on the highway. It bolts directly to the factory mounts on C10, K10, C15 and K15 models, eliminating complicated modifications. With its tig-welded aluminum core and included dual electric fans, it ensures steady airflow and fast heat rejection under load.

Precision TIG Welded Aluminum Core and Tanks

The core and side tanks are joined using TIG welding, which creates a precise, clean fusion that resists cracking under repeated heat cycles. By avoiding flux residue, this method preserves the alloy's natural strength and thermal conductivity. The smooth transition between tubes and tanks maximizes coolant flow and heat transfer. In practice, this means reliable performance whether you're idling in traffic or pushing hard on the open road.

Dual Electric Fans for Steady Temperature Control

Featuring two performance fans, this radiator maintains consistent airflow when engine load climbs or vehicle speed drops. Each fan covers half the core surface to deliver uniform cooling across every fin row, effectively preventing hot spots. In stop and go conditions or under towing stress, the fans ramp up quickly to expel heat, keeping engine temperatures within safe limits. This approach ensures stable operation on city streets, highways, and even at the track.

Finish Options for Corrosion Protection and Style

Available in bare aluminum or a black epoxy coat, the radiator offers both natural patina and added chemical resistance. Bare aluminum develops a subtle sheen over time, while the epoxy option shields against road salt, moisture, and grime. Precision masking during coating preserves port openings and mounting faces for a flawless fit. These choices let you match your cooling upgrade to a restored original or a modern custom build without compromise.

Direct Mount Compatibility with GM C and K Series Trucks

This unit bolts directly to factory mounts on 1963 1966 C10, K10, C15, and K15 trucks, eliminating the need for frame alterations or custom brackets. Hose connections and transmission cooler ports align precisely for automatic applications, simplifying LS and LT engine swaps. Built in the USA, each radiator undergoes dimensional checks to guarantee repeatable fit and finish. The result is a seamless installation and dependable cooling mile after mile.

For the same radiator but without fans see our 1963-1966 GM Truck Radiator Automatic Transmission and count on lasting cooling performance.
