1967-87 C/K SquareBody Dual-Fan Radiator for LS LT Swaps

Achieve unwavering heat control in your C/K Series LS or LT swap with the HD Cooling 20.75" tall radiator's high capacity aluminum core and dual high-performance fans, engineered to handle demanding towing, off road and track conditions while bolting directly into 1967 to 1987 trucks with no modifications. Built in the USA from corrosion resistant materials for lasting reliability, it maintains steady operating temperatures in stop and go traffic and maximizes thermal efficiency to keep your powerplant at peak performance mile after mile.

Heavy-Duty Radiator for LS and LT Engine Swaps in 1967-1987 C/K Trucks, Blazer, Suburban

When fitting a modern LS or LT into a 1967-1987 GM C/K chassis, you need a radiator that slots into factory frame mounts and copes with towing and idling stress. It features a 20.75 inch tall deep aluminum core that increases fluid capacity and heat rejection while preserving underhood clearance. The assembly arrives complete with two electric fans in a single shroud and a temperature sensor harness for reliable airflow during stop and go driving. Designed for direct fitment on C10, K10, Blazer and Suburban frames, this radiator matches original inlet and outlet positions for plug and play installation.

Direct Fitment with Factory Frame Mounts

Installing a modern LS or LT engine into a classic C10 or Suburban chassis often requires custom work. This radiator bolts into the original frame mounting points without extra hardware, preserving factory inlet and outlet locations. That alignment ensures the coolant system follows its intended path and keeps transmission cooler lines in place. By maintaining under hood clearance around steering linkages and wiring, the design reduces interference with other components. Technicians benefit from a simplified assembly that cuts installation time and lowers error risk.

Deep Aluminum Core Enhancing Heat Rejection

At 20.75 inch tall the core offers a large fluid volume that resists heat soak during towing or extended idling. Constructed from high quality aluminum it moves heat away from the engine block faster than older copper designs. An optimized fin density across the full height balances coolant flow with maximum surface area for quicker temperature stabilization. The cell thickness and tube spacing work in tandem to keep operating temperatures in check under heavy load. Its lightweight nature also reduces front mass compared to traditional radiators.

Integrated Dual Electric Fans for Consistent Airflow

This unit arrives preassembled with two 16 inch fans nestled in a single shroud to sweep air through the entire core. A temperature sensor triggers the fans automatically when coolant reaches its threshold so the engine remains within its best performance range in slow traffic. The dual fan approach prevents uneven cooling across the surface and reduces hot spots that can lead to heat related wear. Its wiring harness is ready for plug in connection to the factory harness, avoiding splicing and fitting work. The result is assured airflow when braking or creeping up hills.

Corrosion Protection with Bare Aluminum or Epoxy Finish

The radiator offers a choice of bare aluminum to highlight weld seams or a black epoxy coat for added defense against moisture and road salt. The epoxy bonds tightly to the aluminum and resists flaking, keeping fins clear of debris and preserving airflow. Continuous exposure to harsh climates has minimal impact on its structure or performance. Both finishes maintain consistent coolant flow and thermal transfer over years of service in dusty or coastal environments. This approach ensures lasting durability without altering radiator capacity.

Engineered to deliver steady cooling under towing and idling conditions. For the same radiator but without fans consider our 1967-1987 GM Truck Radiator 20.75" Tall (Automatic Transmission) - HD Cooling.
