Freightliner, Western Star Intercooler - Freightliner BHT79668, Northern Radiator 222249, Spectra Premium 4401-1730, Reach Cooling 61-1247

When your boost temperatures are climbing and you need a reliable charge air cooler for your Freightliner or Western Star, the Reach Cooling 61-1247 is a proven aftermarket direct replacement built to OE standards. It replaces Freightliner 44FR5Y - the OEM reference most technicians reach for first - along with Northern Radiator 222249, Spectra Premium 44011730, 1-800-Radiator 2310304, Serck SRMFR5Y, and Paccar Parts CAC61-1247TRP. Fitment covers a wide range of Freightliner and Western Star equipment, including the Cascadia (2008-2013), Columbia (2008-2011), Coronado (2004-2013), Century Class (2008-2011), Classic (2008-2009), Argosy (2008), M2 106 (2003-2013), M2 112 (2009-2013), 108SD (2012-2013), 114SD (2012-2013), and Western Star 4900EX (2008-2011), 4900FA (2008-2012), and 4900SA (2008-2011). Reach Cooling reinforces the aluminum alloy header with aluminum bronze for 50% greater strength, uses a wider-angle header plate bond to resist cracking, and builds tube walls to a minimum of 0.55mm to handle elevated boost pressures on long hauls. The deep extrusion header creates a stronger tube-to-header joint that stands up to vibration and thermal cycling. Every unit is packaged in a 7-layer heavy-duty corrugated box to arrive ready to install, making this intercooler a straightforward, correct-fit replacement for the Freightliner 44FR5Y.
