LS and LT Engine Swap Radiator for 1967-1987 C/K Series Trucks and Chevy Blazer/Suburban
When converting a 1967-1987 C/K Series truck or Chevy Blazer/Suburban to LS or LT power, keeping engine temperatures in check is essential. The 1967-1987 GM Truck Radiator 20.75 inch tall with fans for automatic transmissions tackles this challenge with a high capacity core and dual high efficiency fans. Constructed from high quality aluminum, it bolts into factory mounts on C10 and K10 chassis as well as Blazer and Suburban models with no extra parts and offers LS and LT compatibility.
Factory Mount Compatibility for C10 K10 and Suburban Models
This radiator is engineered to bolt directly into the original mounts on 1967-1987 C10 and K10 trucks as well as Blazer and Suburban frames. By matching the factory mounting points and hose locations, it eliminates the need for extra brackets or cutting and drilling. As a result, enthusiasts can complete the installation on models equipped with automatic transmissions with confidence, knowing that alignment and clearance have been verified in advance.
High Capacity Aluminum Core Accelerates Heat Rejection
At the heart of this design is a thick, high capacity aluminum core that excels at shedding heat under heavy load. Aluminum's superior thermal conductivity ensures rapid transfer of engine heat into the coolant, while its corrosion resistance helps maintain flow efficiency over time. The increased core volume tames temperature spikes during towing or spirited driving, delivering stable coolant temperatures even in demanding conditions.
Dual Fan Arrangement for Steady Engine Temperatures
Two high-efficiency electric fans are pre-installed to guarantee airflow on demand, whether you're crawling through traffic or punching it at the track. These fans draw air quickly through the core when vehicle speed is low, preventing heat soak and protecting the engine from overheating. The result is a cooling system that responds instantly to temperature changes and keeps thermostat readings in their optimal range.
Custom Finish Options for Durability and Style
Choose a bare aluminum finish to highlight the weld craftsmanship and maintain a classic under-hood look, or opt for a black epoxy coating for extra corrosion protection and a sleek appearance. Both finishes are applied in the USA and stand up to moisture, road salt, and debris. This attention to surface treatment ensures your radiator not only performs at its best but also retains its appearance mile after mile.
