Freightliner Radiator - Freightliner A0526865003, Northern Radiator 238690, Spectra Premium 20011754P, Reach Cooling 42-10512

When your Freightliner Cascadia or Coronado needs a new radiator, the Reach Cooling 42-10512 is the aftermarket direct replacement built to match OE specifications. This unit cross-references Freightliner 0524939003, Northern Radiator 238690, Active Radiator Supply Company 800112PT, 1-800-Radiator 2400004, Serck FLA002277, and NAPA NR4210512, making it easy to confirm you have the right part. The aluminum core and plastic tank construction uses a down-flow design with B-type tubes featuring central reinforcement for greater pressure tolerance, folded fin edges for improved heat disbursement, and thermal expansion cuts that allow the core to breathe through normal heat cycles without compromising integrity. Deep extrusion headers create a stronger tube-to-header joint that resists vibration and thermal expansion, virtually eliminating tube-to-header leaks. A transmission oil cooler is integrated with fittings spaced 12 inches apart, so there is no need to source a separate unit. Fitment covers the Freightliner Coronado from 2010 through 2015 across 12.7L, 12.8L, 14.0L, 14.6L, 14.8L, and 15.6L engines, as well as the Freightliner Cascadia from 2013 through 2015 in 15.6L applications. If you are working from Freightliner part number 0524939003, this is the correct aftermarket replacement to reach for.
