If you are sourcing a replacement radiator for an International ProStar, 8500 TranStar, or 8600 TranStar, Reach Cooling 42-10500 is the aftermarket solution built to match OE fit and performance. This down-flow aluminum core radiator with PA66-GF30 tanks directly replaces Northern Radiator 238626, Active Radiator Supply Company 640102PT, Spectra Premium SPI20013547, 1-800-Radiator 2400243, Serck FLA002236, and NAPA NR4210500. Fitment covers 2009-2018 International ProStar and 8600 TranStar trucks along with 2010-2011 International 8500 TranStar models, spanning engine families from 8.9L through 15.2L. The core measures 35.12 in tall by 40.44 in wide by 2.05 in thick, with a top-left inlet and bottom-center outlet, both at 2.52 in diameter. A transmission oil cooler with fittings spaced 11.5 in apart is included; the radiator cap, frame, and engine oil cooler are not. Reach Cooling engineers these radiators with B-type reinforced tubes, deep extrusion header joints, thermal expansion cuts, and folded fin edges to hold up against the vibration and heat cycling that takes down inferior cores. The multi-fit attachment system ensures broad vehicle coverage without sacrificing a precise, OE-quality installation every time.
