99-12 GM Truck w/ Oil Co oler Radiator

The 99-12 GM Truck with Oil Cooler Radiator from Cold Case Radiators is engineered for truck owners and mechanics seeking reliable thermal management in demanding conditions. This radiator is purpose-built for first and second-generation GMT800-platform trucks—including Chevy Silverado, GMC Sierra, Cadillac Escalade, and Chevrolet Tahoe models—where integrated oil cooling is essential to maintain safe engine temperatures under towing, hauling, or spirited driving. The integrated oil cooler design consolidates cooling into a single efficient unit, reducing under-hood complexity while improving heat dissipation.

Cold Case Radiators manufactures this unit using modern all-aluminum construction with brazed tanks, delivering superior heat transfer and durability compared to traditional copper-brass designs. The integrated transmission and engine oil cooler circuits allow simultaneous cooling of both fluids without sacrificing radiator core capacity, critical when operating in high-load scenarios such as mountain passes, heavy towing, or off-road use. The core design balances fin density with low restriction airflow, ensuring your electric fan works efficiently while preventing thermostat cycling issues. At 25.53 pounds and measuring 25 by 8 by 44 inches, the unit fits OEM mounting points with no modification, making installation straightforward for both shop and owner-mechanic installations.

Buyers upgrading from aging factory radiators—especially those experiencing overheating, coolant leaks, or frequent fan engagement—will see immediate improvements in temperature stability and engine longevity. Performance truck owners running modified engines, superchargers, or aggressive driving profiles benefit most from the increased thermal capacity and oil cooling integration. This radiator is direct-fit for 1999–2012 GM light-duty trucks and SUVs equipped with the 5.3L, 6.0L, or 8.1L engines, with proper hose connections and factory-style mounting tabs ensuring hassle-free installation without adapters or rework.
