Freightliner Radiator - Freightliner HDC011049P, Northern Radiator 238863, OEM 1003731, Reach Cooling 42-10974

When your Freightliner needs a reliable radiator replacement, the Reach Cooling 42-10974 is a proven aftermarket solution built to meet or exceed OE specifications. This down-flow radiator features an aluminum core and plastic tanks with a core height of 40 inches, a core width of 31.81 inches, and a core thickness of 1.89 inches, with 2.52-inch inlet and outlet diameters positioned top-right and bottom-left respectively. It directly replaces Freightliner HDC011049P - the primary OEM interchange - along with Northern Radiator 238863 and OEM 1003731. Fitment covers a broad range of Freightliner models including the B2, MB Line, S2, S2C, XB Line, XB Straight Rail, and XBA, spanning model years 2010 through 2016 across engine displacements from 5.9L up to 10.8L. Reach Cooling's design incorporates B-type tubes with central reinforcement for greater pressure tolerance, deep extrusion headers for superior resistance to vibration and thermal expansion, folded fin edges for added stability and heat dissipation, longer header tabs for tank-to-header leak prevention, and thermal expansion cuts that allow the core to breathe through normal heat cycles. The result is a direct-fit, long-lasting replacement that installs correctly the first time and keeps your Freightliner running cool.
