Keep your Freightliner or Sterling Truck running cool with the Reach Cooling 42-10390 aftermarket radiator, a direct replacement for Freightliner 525340012. This unit also cross-references Northern Radiator 238614, Active Radiator Supply Company 900053ST, Spectra Premium SPI20011748, Serck FLA000294, and NAPA NR4210390, making it straightforward to confirm you have the right part. The aluminum core is built with B-type tubes featuring central reinforcement for greater pressure tolerance, while deep extrusion headers create a stronger tube-to-header joint that resists vibration and thermal expansion, dramatically reducing the chance of leaks. Folded fin edges improve stability and heat disbursement, and thermal expansion cuts allow the core to breathe through normal heat cycles, extending service life. A transmission oil cooler is included with fittings spaced 18 inches apart, and the filler neck is included as well. This down-flow radiator fits the 2008-2013 Freightliner M2 106, 2009-2013 Freightliner M2 112, and 2008-2010 Sterling Truck Acterra across a range of engine displacements. Whether you are ordering for a single truck or a fleet, this aftermarket radiator delivers OE-quality fit and function so you can get back on the road with confidence.
