Freightliner, Western Star Radiator - Freightliner A0210810003, Active Radiator Supply Company 800104PT, Serck FLA000292, Reach Cooling 42-10647

The Reach Cooling 42-10647 is an aftermarket heavy-duty radiator engineered as a direct replacement for Freightliner Cascadia, M2 112, and Western Star 5700XE trucks. It replaces Freightliner OEM part number 0530990003 and cross-references Active Radiator Supply Company 800104PTV, Serck FLA002207, Keystone Auto Industries HDC010831PAF, Cancore Industries FRE90, and Northern Factory Sales 238736. The aluminum core and plastic tank construction meets or exceeds original equipment specifications, while B-type tubes with central reinforcement deliver greater pressure tolerance and dramatically reduced risk of tube failure. Deep extrusion headers create a stronger tube-to-header joint that resists vibration and thermal expansion, and folded fin edges add stability and improve heat disbursement. Thermal expansion cuts allow the core to flex through normal heat cycles, extending service life and reducing failure rates. The down-flow design features a top-right inlet and bottom-left outlet, each measuring 2.52 inches in diameter, with a core measuring 35.67 inches tall, 38.5 inches wide, and 2.2 inches thick. Coverage spans Freightliner Cascadia models from 2012 through 2018, Freightliner M2 112 models from 2012 through 2014, and Western Star 5700XE models from 2016 through 2018 across a wide range of engine displacements. If you are searching by Freightliner 0530990003 or any of its known interchanges, this is the correct direct-fit replacement.
