63-66 C/K Series Radiator with LS LT Dual Fans

Reliable engine and transmission temperature control comes from a 100% TIG welded aluminum core with precision aluminum tanks and integrated transmission cooler designed for 1963 to 1966 C/K Series trucks. Dual electric fans and robust mounting hardware ensure superior thermal efficiency, corrosion-resistant durability and a precise fit for LS and LT conversions in C10, C15, K10 and K15 models.

Radiator with Fans for LS and LT Swaps in 1963-1966 C/K Series Trucks

Dropping an LS or LT engine into a 1963 to 1966 C/K Series pickup exposes the limits of stock cooling and can lead to overheating when towing or in traffic. The 1963-1966 GM Truck Radiator (Auto Trans) with Fans features a TIG welded aluminum core and a built in transmission cooler port for easy plumbing. Under load dual electric fans engage automatically to deliver airflow across the core and keep engine and transmission temperatures in check under towing and low speed driving. It bolts directly to factory C and K frame mounts with all hardware for a precise fit in C10 C15 K10 and K15 trucks and is made in the USA for reliable service.

Precision TIG Welding for Core Integrity

The radiator's core and side tanks are joined by TIG welding to deliver uniform strength and zero leaks under stress. This process fuses high quality aluminum without filler material that could impede thermal conductivity, preserving smooth coolant passages. The consistent weld bead resists cracking during constant cycles of heating and cooling, eliminating weak spots and hotspots. By maintaining full crossflow of coolant and air, the assembly transfers heat reliably from fluid to airflow. This robust construction supports stable engine and transmission temperatures even under heavy towing in stop and go traffic or on long climbs.

Dual Fan System for Active Cooling

Dual electric fans are mounted directly to the front face of the radiator to move air evenly across every tube and fin. Each fan covers half of the core to prevent warm pockets from forming under load. They activate automatically when sensors detect rising coolant temperature, initiating airflow before engine or fluid temps exceed safe limits. This rapid response is essential for towing or city driving where speed alone cannot draw enough air through the core. The design also directs air through the built in transmission cooler port to protect transmission fluid from heat soak in low speed conditions.

Finish Options for Corrosion Resistance

Consumers can select a natural bare aluminum finish or a durable black epoxy coat based on style and maintenance needs. The bare option develops an authentic patina over time that complements classic restorations, while the epoxy layer shields the surface from moisture, road salt and chemical exposure. Precision masking around mounting pads and cooler ports ensures that critical sealing and alignment surfaces remain pristine during coating. This careful attention to detail not only enhances corrosion resistance but also maintains the accuracy of hose connections and mounting precision for a clean result.

Direct Fit Frame Mount for Easy Installation

The radiator bolts directly to factory C and K frame mounts using supplied hardware for a precise fit that mirrors original equipment installation. Its dimensions align with the stock cradle so no modifications to the frame or core support are required. The built in transmission cooler port matches standard automatic plumbing locations to keep hose routing tidy and minimize complexity. By combining drop in placement with familiar connections, this design reduces installation time and potential error points, allowing builders to focus on other aspects of the engine swap with confidence in cooling performance.

For the same radiator but without fans consider our 1963-1966 GM Truck Radiator Automatic Transmission and trust MuscleRods for dependable cooling performance.
