International Radiator - Active Radiator Supply Company 6400-93, OEM 2604461C91, Reach Cooling 42-10991

If your International WorkStar 7600 or WorkStar 7700 needs a new radiator, the Reach Cooling 42-10991 is the aftermarket direct replacement built to meet or exceed OEM specifications. This unit cross-references OEM 1003716 and Active Radiator Supply Company 6400-93, making it straightforward to confirm the right fit before you order. The aluminum core and plastic tank construction follows a down-flow design, with reinforced B-type tubes that offer greater resistance to pressure and dramatically reduce the chance of tube failure. Deep extrusion headers strengthen the tube-to-header joint to withstand vibration and thermal expansion, virtually eliminating header leaks, while folded fin edges improve stability and heat transfer. Thermal expansion cuts allow the core to breathe naturally through heat cycles, extending service life and reducing failure rates. Longer header tabs add further pressure resistance at the tank-to-header seam. Covered applications include the 2010-2014 WorkStar 7600 in 10.5L, 10.8L, and 12.4L configurations, the 2010-2011 WorkStar 7600 12.5L, and the 2010-2012 WorkStar 7700 10.8L. When OEM 1003716 is what you need replaced, Reach Cooling 42-10991 delivers the correct fit and the durability your fleet demands.
