1967-1987 Squarebody C/K Trucks and Blazer/Suburban Radiator for LS and LT Swaps
If your project calls for precise coolant management in a classic 1967 to 1987 SquareBody C/K truck or Blazer/Suburban swap with an LS or LT engine, the 1967-1987 GM Truck Radiator 18.5" Tall (Manual Trans) with Fans is engineered to fit factory mounts and align coolant hoses without trimming. Equipped with an aluminum core and dual electric fans it sustains steady airflow during stop and go driving or under towing load. Each inlet, outlet and bracket mirrors stock positions on C10, C15, K10, K15, Blazer and Suburban frames so transmission cooler lines connect directly. Technicians will value the ready to install design that cuts installation time and minimizes leak points in the cooling circuit.
Precision Fitment for Classic C K Series Trucks
This 18.5 inch radiator has been engineered to match the exact core height and bracket spacing used on 1967 through 1987 C10, C15, K10, K15, Blazer, and Suburban frames. By mirroring factory dimensions, coolant hoses and transmission cooler lines connect without the need for adapters or trimming. Installers benefit from a genuinely drop in solution that preserves the vintage under hood appearance and eliminates guesswork. The precise alignment also reduces stress on hoses and fittings, helping to prevent leaks over time. Whether restoring a weekend cruiser or building a tow rig, this radiator offers straightforward installation and consistent coolant management.
Dual Fan Configuration Ensuring Consistent Airflow
Equipped with two electrically driven fans, this assembly maintains airflow even at idle or in stop and go traffic. Each fan is calibrated to engage as coolant temperature rises, promoting uniform air delivery across the entire aluminum core. This approach minimizes hot spots and resists heat soak when under heavy load or during extended idling. Pre-wired fan connectors eliminate the need for aftermarket switches or relays, simplifying the wiring process. The result is dependable engine cooling that responds dynamically to changing driving conditions.
Aluminum Core Efficiency with Selectable Coating Style
Constructed from high quality aluminum, the radiator core offers superior thermal conductivity compared to traditional copper brass designs, allowing rapid heat rejection from the engine. An optimized tube and fin arrangement increases coolant volume and enhances heat transfer, which is critical during sustained highway runs or towing duty. Aluminum's natural resistance to rust extends service life and reduces maintenance intervals. Customers can choose between a classic bare metal finish for minimal weight or a black epoxy coat that provides extra surface protection and a refined engine bay appearance.
Domestic Manufacturing for Reliable Operation
Built entirely in the United States, each radiator core, fan shroud, and mounting bracket undergoes meticulous in house inspection to guarantee consistent fit and function. This local production model not only supports skilled craftsmen but also shortens lead times for replacements and warranty service. Tight tolerance standards ensure that every unit arrives ready to install, reducing the chance of post-purchase issues. The commitment to domestic manufacturing translates into confidence for installers and vehicle owners alike, delivering reliable engine cooling under all driving scenarios.
