Freightliner, Sterling Truck Radiator - Freightliner 3E0122800003, Northern Radiator 238611, Spectra Premium 20011723F, Reach Cooling 42-10290

When your Freightliner Cascadia, Century Class, or Columbia is running hot, or your Sterling Truck L9500 needs a new radiator, Reach Cooling 42-10290 is the aftermarket direct replacement built to get you back on the road. This radiator replaces Freightliner 0527749003 - the OEM reference - and also cross-references Northern Radiator 238611, Active Radiator Supply Company 800057ST, Spectra Premium 2001-1723, Serck S8057, and NAPA 20011723. The aluminum core and plastic tank construction meets or exceeds original equipment specifications, and the included transmission oil cooler means no hunting for a separate part. Reinforced B-type tubes with central ribbing resist pressure and dramatically reduce the chance of tube failure, while deep extrusion headers provide a stronger tube-to-header joint that stands up to vibration and thermal cycling. Folded fin edges improve heat dissipation, and thermal expansion cuts allow the core to breathe through normal heat cycles, extending service life. This radiator covers Freightliner Cascadia models from 2008 through 2013, Freightliner Century Class and Columbia models from 2008 through 2011, and Sterling Truck L9500 models from 2009 through 2010, spanning engine sizes from 8.3L up to 15.6L. If you are sourcing by Freightliner 0527749003 or any of the listed cross-references, this is the correct aftermarket fit.
