Freightliner, Sterling Truck Radiator - Freightliner 527749003, Northern Radiator SCSI239195, Spectra Premium 2001-1723, Reach Cooling 42-10293

The Reach Cooling 42-10293 is an aftermarket radiator built as a direct replacement for Freightliner and Sterling Truck cooling systems, cross-referencing Freightliner 2400748, Northern Radiator 239195, Active Radiator Supply Company 8000-57, Spectra Premium 20011723, 1-800-Radiator 2403406, and Serck FLA000266. This down-flow unit features an aluminum core and plastic tanks, includes a transmission oil cooler, and is engineered to meet or exceed OE specifications. Fitment covers Freightliner Cascadia model years 2008 through 2013, Freightliner Century Class 2009 through 2010, and Freightliner Columbia 2008 through 2011, along with Sterling Truck L9500 2009 through 2010, across a broad range of engine displacements from 8.3L up to 15.6L. Reach Cooling's B-type tubes incorporate central reinforcement for elevated pressure tolerance, while deep extrusion headers strengthen the tube-to-header joint against vibration and thermal cycling. Folded fin edges improve heat disbursement, and thermal expansion cuts allow the core to expand and contract naturally, reducing long-term failure rates. Longer header tabs add pressure resistance and minimize tank-to-header leaks. If you are sourcing by Freightliner 2400748 or any of the listed cross-references, this radiator delivers the correct fit and the durability your truck demands.
