Freightliner, Sterling Truck Radiator - Freightliner 0437116S, Northern Radiator SCSI239455, Spectra Premium 2001-1704, Reach Cooling 42-10003

When your Freightliner or Sterling Truck radiator needs replacing, Reach Cooling 42-10003 is the aftermarket solution built to get you back on the road. This unit directly replaces Freightliner 05-16378-001 and cross-references Northern Radiator 239011, Active Radiator Supply Company 8000-04PT, Spectra Premium 2001-1704, 1-800-Radiator 2400579, and Serck FLX000203, making it straightforward to verify you have the right part before you pull the old one. The aluminum core and plastic tanks are engineered to meet or exceed original equipment specifications, and the B-type tubes with central reinforcement provide greater resistance to pressure and reduce the probability of tube failure in demanding service. Deep extrusion headers create a stronger tube-to-header joint that stands up to vibration and thermal cycling, virtually eliminating those chronic header leaks that sideline trucks. Folded fin edges add structural stability and improve heat dissipation, while thermal expansion cuts allow the core to breathe through normal heat cycles for extended service life. Fitment covers Freightliner Century Class, Classic, FL106, FL112, FL70, FL80, FLD112, FLD120, FLD120SD, M2 106, and MB Line, along with Sterling Truck L7500, L8500, LT7500, and LT8500. If Freightliner 05-16378-001 is what you are cross-referencing, Reach Cooling 42-10003 is a confirmed, correct-fit direct replacement.
