Sterling Truck Radiator - Northern Radiator 239171, Active Radiator Supply Company 3100-10, 1-800-Radiator 2400993, Reach Cooling 42-10445

When your Sterling Truck Acterra needs a new radiator, the Reach Cooling 42-10445 delivers a reliable aftermarket replacement engineered to meet or exceed OE specifications. This cross-flow radiator features an aluminum core and PA66-GF30 plastic tanks, with B-type tubes reinforced at the center for greater pressure resistance and a dramatically reduced chance of tube failure. Deep extrusion headers strengthen the tube-to-header joint to stand up to vibration and thermal expansion, while folded fin edges improve heat disbursement and structural stability. Thermal expansion cuts allow the core to breathe naturally through normal heat cycles, extending service life, and longer header tabs resist tank-to-header leaks over the long haul. A transmission oil cooler is included.
