Freightliner Radiator - Freightliner 1050509C, Spectra Premium 20011777P, Superior Cooling Systems 238871, Reach Cooling 42-11140

If your Freightliner M2, M2 106, or M2 112 needs a new radiator, the Reach Cooling 42-11140 is a direct aftermarket replacement built to meet or exceed OE specifications. It cross-references Freightliner 1050509C, Superior Cooling Systems 238871, and OEM 1040587A, making it straightforward to confirm you have the right part. The aluminum core features B-type tubes with central reinforcement for greater pressure tolerance and dramatically reduced risk of tube failure, while the deep extrusion header creates a stronger tube-to-header joint that resists the stress of vibration and thermal expansion. Thermal expansion cuts in the core allow for natural expansion and contraction during heat cycles, extending service life and reducing failure rates. Folded fin edges add stability and improve heat disbursement, and longer header tabs provide additional pressure resistance to prevent tank-to-header leaks. The downflow design includes an integrated plate-type engine oil cooler and multi-fit attachments that allow this single radiator to cover multiple M2 applications across model years 2018 through 2025. With the correct fitment for Freightliner M2, M2 106, and M2 112 and a build quality that mirrors OE performance, Reach Cooling 42-11140 is the dependable replacement for Freightliner 1050509C your truck needs.
