Freightliner Radiator - Freightliner 2400416, Northern Radiator SCSI239139, Spectra Premium 2001-1724, Reach Cooling 42-10059

When your Freightliner needs a reliable radiator replacement, the Reach Cooling 42-10059 delivers aftermarket performance engineered to meet or exceed OE specifications. This radiator is a direct replacement for Freightliner 376761561 and cross-references Northern Radiator 239139, Active Radiator Supply Company 800032, Spectra Premium 2001-1724, 1-800-Radiator 2400037, and Serck FLX000237, making it straightforward to confirm you have the correct part. The aluminum core uses B-type tubes with central reinforcement for greater pressure tolerance and drastically reduced risk of tube failure, while deep extrusion headers create a stronger tube-to-header joint that stands up to vibration and thermal cycling without leaking. Folded fin edges add structural stability and improve heat disbursement, and thermal expansion cuts allow the core to breathe through normal heat cycles for longer service life. The two-row down-flow design features plastic tanks, a top-left inlet and bottom-right outlet, each measuring 2.5 inches in diameter. This unit fits Freightliner Century Class, Columbia, FL60, FL70, M2 106, and M2 112 trucks across a wide range of engine displacements. If you are sourcing by OEM number or shopping by model, the 42-10059 is the right fit for trucks that originally carried Freightliner 376761561, and it installs as a correct, confidence-inspiring direct replacement.
