When your charge air cooler is leaking or failing, the Reach Cooling 61-1246 is the aftermarket replacement built to get your truck back on the road with confidence. This intercooler directly replaces Freightliner 0131241000, the OEM reference for this application, and also cross-references Northern Radiator 222235, Spectra Premium 44011719, 1-800-Radiator 2310278, Serck FLX010243, and Keystone Auto Industries WSR1107K. The aluminum core measures 820mm long by 881mm tall by 62mm thick, with a harmonica-style tube design, reinforced tube walls at no less than 0.55mm thickness, deep extrusion headers for a stronger tube-to-header joint, header plates reinforced with aluminum bronze for 50% greater strength, and a reinforcing rib on each tube to handle vibration and thermal expansion over the long haul. The inlet is located top left and the outlet center right, both at a 4-inch outside diameter. Fitment covers Freightliner Cascadia, Columbia, Century Class, Classic, Coronado, Argosy, FLD120SD, M2 112, and B2; Sterling Truck A9500, AT9500, L9500, and LT9500; and Western Star 4900EX, 4900FA, and 4900SA spanning model years 2008 through 2021. If you are sourcing by OEM number or cross-referencing from Northern Radiator 222235 or Spectra Premium 44011719, Reach Cooling 61-1246 is the confirmed aftermarket replacement for a bolt-in fit.
