1967-87 C/K SquareBody Radiator with Dual Fans for LS LT Builds

Delivering reliable cooling under the toughest conditions, the 1967-1987 GM Truck Radiator 20.75" Tall with dual fans integrates a high-capacity aluminum core that conquers heat spikes during towing, heavy hauling, and track use while bolting directly into C/K Series bodies with no modifications. Made in the USA from rustproof aluminum for lasting durability, it maintains steady temperatures in stop and go traffic and maximizes thermal efficiency to keep LS and LT powerplants running at peak performance across C/K Series trucks.

1967-1987 GM C/K Truck and Blazer Suburban 20.75" Radiator for LS and LT Engine Swaps

Placing a modern LS or LT powerplant into a 1967 to 1987 Chevy or GMC C/K Series truck demands a robust cooling solution that fits the factory frame mounts without extra brackets. This 20.75 inch tall radiator tackles that need with a deep aluminum core and preinstalled electric fan assembly wired to a temperature sensor for reliable airflow at low speeds. In addition to matching hose inlet and outlet positions on C10, K10, Blazer and Suburban chassis, the unit offers corrosion resistance and lightweight strength that preserve under hood clearance. Designed for direct fitment, it keeps coolant flowing at consistent rates during towing or urban traffic and simplifies installation through plug and play connections.

Factory Frame Mount Alignment on C/K Series Chassis

This radiator bolts directly into the original frame mounting points on 1967 to 1987 C10, K10, Blazer and Suburban models, eliminating the need for custom brackets or frame modification. By matching the factory hose inlet and outlet locations, it preserves the intended coolant routing and ensures a precise fit without interference. Underhood clearance remains factory correct, preserving room for steering linkages and electrical harnesses. Technicians benefit from a streamlined installation process that reduces labor time and risk of alignment errors. The direct fit design also keeps transmission cooler lines in their proper position, preventing stress on hoses under load.

Deep Aluminum Core Delivering Superior Thermal Transfer

At 20.75 inches tall, the deep aluminum core provides increased fluid capacity and a larger surface area for heat exchange, taming engine temperatures during towing or extended idle periods. Aluminum's high thermal conductivity moves heat away from the engine block faster than traditional materials, helping to prevent heat soak under heavy load. The core design balances efficient flow rates with optimal fin density to maintain stable coolant temperature even under severe driving conditions. Its lightweight construction reduces front end mass compared to older copper based designs, improving weight distribution. Made in the USA from high quality aluminum, this core delivers consistent performance over years of use.

Dual Electric Fans for Consistent Low Speed Airflow

This radiator comes with two electric fans preinstalled in a single shroud, drawing air evenly across the full core when vehicle speed alone cannot provide sufficient cooling. Fans engage automatically via a temperature sensor signal, eliminating the guesswork and protecting the engine during traffic or steep hill climbs. Even airflow distribution prevents local hot spots, keeping the powerplant within its optimal temperature window. The wiring harness and mounting bracket arrive ready for a quick connection, simplifying final assembly and minimizing wiring changes. This integrated solution ensures reliable airflow without the need for aftermarket adapters.

Bare Aluminum and Epoxy Finishes for Lasting Resistance

Customers can choose a natural bare aluminum finish to showcase precise weld seams and machined surfaces, or select a black epoxy coating to guard against moisture, road salt and corrosion. The industrial grade epoxy is applied in the United States and bonds tightly to the aluminum, preventing flaking or degradation over time. Both finishes maintain clear coolant passages and resist environmental wear even in harsh climates. The protective layers help preserve appearance and performance, ensuring that cooling efficiency remains unchanged through years of service. Whether you prefer the showroom look of raw metal or a stealth black cover, each option delivers durable corrosion resistance.

This robust radiator delivers steady engine temperatures during every drive and for the same radiator but without fans see our 1967-1987 GM Truck Radiator 20.75" Tall (Automatic Transmission) - HD Cooling.
