Dual-Fan HD Radiator for LS and LT in 1967-1987 C/K Trucks

Heavy-duty aluminum construction provides superior heat rejection for towing or daily driving in your C/K Series SquareBody powered by LS or LT engines. The 20.75 inch core and dual fans bolt in without trimming or mods to maintain consistent coolant flow under load and on the track.

1967-1987 C/K Series SquareBody Radiator for LS and LT Engine Swaps

Swapping an LS or LT motor into a 1967-1987 C/K Series truck demands a radiator that balances classic fit with robust cooling. This 20.75 inch tall unit with dual electric fans slips into manual transmission C10, K10, Blazer and Suburban frames without trimming or adjustment. When traffic slows or the engine hauls heavy loads, the fans sustain airflow to prevent coolant temperatures from climbing. Precise inlet and outlet ports mirror stock positions to ensure LS and LT compatibility and simplify hose routing.

Thickwall Aluminum Core Delivers High-capacity Cooling

The 20.75 inch tall core is crafted from thickwall aluminum that absorbs and transfers heat rapidly when towing or under sustained load with an LS or LT swap. This high-capacity design lowers peak coolant temperatures and resists warping under repeated thermal cycling. Aluminum's innate resistance to corrosion helps maintain peak performance over years of exposure to road salt and moisture. Lightweight construction also reduces front end mass, preserving the truck's original handling and braking balance. Each core is Made in the USA with precision welds that ensure long term structural integrity.

Dual Electric Fans Ensure Consistent Airflow in Traffic

Two pre installed electric fans maintain airflow through the core even when vehicle speed slows to a crawl or during extended idle periods. By engaging only when needed, they prevent heat soak in stop and go conditions without drawing power continuously from the engine. The fans are mounted in a molded shroud that directs air evenly across the entire core surface, eliminating hot spots. This approach improves thermal management for modern powertrains, keeping coolant temperatures within the optimal range whether on the highway or in town.

Precision Bolt In Fit for 1967 to 1987 C K Series Trucks

Designed specifically for C10, K10, Blazer and Suburban models with manual transmission, this radiator installs directly into the factory frame rails with no cutting or spacing adjustments. Inlet and outlet ports align exactly with LS and LT hose connections, streamlining plumbing and avoiding kinks. By preserving all original mounting locations, the unit resists vibration and stays firmly in place under heavy use. The exact fitment reduces installation time and ensures a seamless integration of modern cooling capability into a classic chassis.

Protective Bare or Black Epoxy Finish for Lasting Durability

Choose a polished bare aluminum surface for a classic engine bay look or opt for a black epoxy coating that adds a matte finish and extra defense against corrosion. Both finishes seal the core and end tanks against moisture and debris, extending service life in harsh environments. The black epoxy also masks minor blemishes and simplifies cleaning after off road excursions or heavy towing. Regardless of choice, each finish preserves the radiator's reliable performance and contributes to visual appeal under the hood.

Built for reliable cooling in LS and LT swaps, this radiator stands up to heavy use. For the same radiator but without fans, consider our 1967-1987 GM Truck Radiator 20.75" Tall (Manual Transmission) - HD Cooling.
