Keep your International medium-duty truck running cool with the Reach Cooling 42-10415 aftermarket radiator, a direct OE-quality replacement for 2012-2013 International 4300, 4400, and Durastar models. This cross-flow aluminum-core, plastic-tank radiator crosses to Northern Radiator 238729, Active Radiator Supply Company 640112, 1-800-Radiator 2401066, Serck FLA000797, NAPA NR4210415, and Paccar Parts RAD42-10415TRP, so you can confirm the correct fit no matter which reference you have on hand. The core measures 36.61 in. tall by 27.64 in. wide by 2.2 in. thick and includes an integrated transmission oil cooler with fittings spaced 20.67 in. apart, covering the full range of engine options from the 6.4L through the 9.3L across 4300, 4400, and Durastar applications. Reach Cooling designs these radiators with reinforced B-type tubes, deep extrusion headers, and thermal expansion cuts to resist tube failure, vibration, and the stress of repeated heat cycles. Folded fin edges improve stability and heat disbursement, while longer header tabs reduce the risk of tank-to-header leaks. If you are sourcing a replacement radiator for a 2012 or 2013 International 4300 or 4400, this is the part that goes straight in and performs like the original.
