When swapping an LS or LT engine into a 1967 to 1987 GM C/K truck, GMC Blazer or Chevy Suburban, the 1967 to 1987 GM Truck Radiator 18.5" Tall (Manual Trans) with Fans delivers reliable cooling for manual transmission applications. Featuring dual electric fans and a tall core design, this radiator maintains stable coolant temps even in traffic or under load while its LS and LT compatibility simplifies installation. It installs in factory brackets on C/KSeries squarebody frames without extra fabrication and complements the classic engine bay layout.
Precision 18.5 Inch Tall Core Ensuring Consistent Temperature Control
The 18.5 inch tall core design significantly increases coolant volume and surface area, which helps dissipate heat more efficiently under heavy load or in stop-and-go traffic. By maintaining a larger reservoir of coolant, this radiator prevents rapid temperature spikes and hot spots that can lead to engine stress. Its manual transmission height profile aligns perfectly with factory mounting points, ensuring reliable cooling performance without compromising the classic engine bay layout.
Optimized Dual Electric Fans for Steady Airflow
Equipped with two high airflow electric fans, this radiator delivers continuous air movement through the core even at low vehicle speeds. The fan setup activates as coolant temperatures rise, providing immediate heat rejection when you're idling or climbing steep grades. This approach not only protects against overheating but also reduces engine load by maintaining stable temperatures, which can improve throttle response and overall drivability.
High Quality Aluminum Construction for Durability and Weight Savings
Constructed from premium aluminum, the radiator offers exceptional strength while remaining lightweight compared to traditional copper-brass units. Aluminum's natural corrosion resistance extends service life, particularly in harsh road environments or varying climates. The choice of domestic manufacture ensures tight tolerances and consistent quality control, giving enthusiasts confidence in long-term reliability.
