1967-87 C/K SquareBody LS LT Radiator with Dual Fan Cooling

High capacity aluminum core construction delivers consistent cooling during heavy towing, stop and go traffic and track use, while the 20.75 inch tall design with dual fans installs directly into 1967-1987 C/K Series trucks without extra modifications. Built in the USA for corrosion resistance and dependable thermal efficiency, this radiator ensures lasting performance for LS and LT engine swaps across C10 and K15 Chevy and GMC trucks, as well as Chevy Blazer and Suburban models.

1967-1987 Chevy/GMC C/K Series Truck Radiator for LS and LT Engine Swaps Blazer Suburban

Swapping a modern LS or LT powerplant into a 1967 to 1987 Chevy or GMC C/K Series truck creates new cooling demands; the 1967 to 1987 GM Truck Radiator 20.75 inch tall with dual electric fans meets that challenge with a deep aluminum core that bolts directly to the factory frame mounts. Its efficient core helps shed heat while towing or crawling through urban traffic and the pair of fans engage via a thermostat signal to maintain airflow at low speed. Installing without cutting or custom brackets, this radiator aligns precisely with hose inlets and transmission cooler lines on C10, K10, Blazer and Suburban chassis. It delivers corrosion resistance, lightweight durability and consistent coolant flow that keep the engine within its ideal temperature range.

Factory Mount Compatibility for LS LT Swaps on SquareBody Chassis

This radiator is engineered to bolt directly into the original frame mounting points on 1967 to 1987 C10, K10, Blazer, and Suburban models when installing a modern LS or LT powerplant, with no cutting or bracket fabrication required. Matching the factory hose connections ensures that inlet and outlet lines align precisely, preserving the intended coolant flow path and minimizing install time. This plug in design maintains under hood clearance and keeps transmission cooler lines in their correct positions. Technicians benefit from a streamlined process that reduces the risk of interference with steering components and wiring harnesses.

High Capacity Aluminum Core Optimized for Heat Rejection

At a 20.75 inch height, the deep aluminum core offers ample volume for coolant circulation and rapid dissipation of engine heat. Aluminum's natural conductivity moves thermal energy away from the engine block faster than traditional materials, reducing temperature spikes during heavy towing or extended urban driving. The core design balances high flow values and efficient surface area to maintain steady coolant temperature under load. Lightweight construction also contributes to improved front weight distribution compared to copper based radiators.

Integrated Dual Fans Ensuring Consistent Airflow at Low Speed

Two electric fans are preinstalled in a single shroud to deliver uniform airflow when road speed alone cannot cool the engine. Triggered by a thermostat signal, the fans pull air evenly across the full core surface to eliminate hot spots in stop and go conditions. This approach keeps the engine within its optimal temperature range during traffic jams or steep climbs. The wiring harness and mounting plate come ready for quick hook up, further simplifying final installation.

Bare Aluminum or Black Epoxy Finish for Corrosion Protection and Style

Customers can choose the classic bare aluminum finish to highlight the precise welds and machined surfaces or opt for a black epoxy coating to shield against moisture, road salt, and electrochemical wear. The industrial grade epoxy is applied in the USA and bonds tightly to the aluminum surface, preventing flaking or rust formation. Both finish options maintain clean coolant pathways and resist degradation over years of use. The result is a durable exterior that preserves looks and performance even in harsh conditions.
