1963-1966 C/K Trucks Radiator for LS LT Conversions

Precision crafted 100% TIG welded aluminum tanks and core deliver superior thermal efficiency, rapid heat rejection and corrosion resistance to keep your LS or LT conversion running cool under heavy demand. Made in the USA for exact compatibility with 1963-1966 C10, C15, K10 and K15 Chevy and GMC trucks with automatic transmissions, this radiator offers lightweight durability, dependable performance and a reliable finish that protects resale value.

LS and LT Engine Swap Radiator for 1963-1966 C/K Series Chevy & GMC Trucks

When you retrofit an LS or LT V8 into a 1963-1966 C10, C15, K10 or K15 frame the stock cooling setup often fails to handle combined engine and transmission heat loads. This 1963-1966 GM Truck Radiator (Auto Trans) uses a crossflow finned core and integrated transmission passages crafted from high grade aluminum to shed weight and maintain stable fluid temperatures under towing or highway use. Installation is simplified by factory matched inlet and outlet ports that align precisely with the C K Series chassis, eliminating adapter fittings and ensuring balanced coolant circulation. Aluminum construction resists corrosion and the TIG welded tanks guarantee a leak resistant seal for long service life.

Precision TIG Welding for Durable Seam Strength

TIG welding delivers consistent weld beads across both tanks and core joints. By controlling heat input these welds preserve the aluminum grain structure and avoid weak zones that can develop in soldered or bolted connections. The result is a leak free seal that stands up to vibration during towing and daily use. Uniform welds also add rigidity to the assembly which reduces fatigue over thousands of miles on highways or steep grades. This technique contributes significantly to long term reliability in demanding swap applications.

Efficient Crossflow Core with Built In Transmission Passages

The crossflow finned core channels coolant laterally through engine and transmission circuits to balance heat load between both systems. Aluminum's high thermal conductivity accelerates heat transfer while the fin arrangement increases surface area for faster rejection. Integrated transmission passages eliminate the need for external coolers or adapters and reduce fluid temperature spikes during heavy load or uphill climbs. This synergy between core design and material choice helps maintain stable operating temperatures under constant highway speed or towing conditions. It also eases the work required by cooling fans for more consistent performance.

High Quality Aluminum with Bare or Epoxy Finish

Constructed entirely from premium grade aluminum this radiator sheds weight compared to the original steel unit and resists corrosion without added layers. A natural bare surface forms its own oxide barrier that prevents rust while offering a classic appearance under the hood. Alternatively the black epoxy finish provides a uniform protective coat that guards against road salt and moisture without impeding heat flow. Both finishes are applied in the US to exacting standards for lasting durability. This choice of coating ensures the unit remains efficient and retains its visual appeal over many seasons.

Direct Port Alignment for Simplified 1963-1966 Installation

The factory matched inlet and outlet ports align precisely with the cooling lines and frame rails of 1963-1966 C10, C15, K10 and K15 trucks so no adapter fittings are required. This direct fit approach saves hours in the shop by eliminating custom modification and assures correct hose routing for balanced coolant flow. Shedding nearly twenty pounds over the stock radiator also reduces front end weight and improves steering response. Installers benefit from a clear engine bay layout and secure mounting to factory brackets for a professional finish. The straightforward process reduces points of failure and streamlines swap projects of all skill levels.
