When your 2012-2015 Freightliner 114SD needs a new radiator, the Reach Cooling 42-10509 delivers an aftermarket replacement built to meet or exceed original equipment specifications. This heavy-duty aluminum-core radiator with plastic PA66-GF30 tanks directly replaces Freightliner 30100R and cross-references 1-800-Radiator 2401199, Serck FLA002274, NAPA NR4210509, OSC HD9231, and OEM 0525303003. Engineered specifically for the 114SD 12.8L application, it features B-type tubes with central reinforcement for superior pressure tolerance, deep extrusion headers that resist the effects of vibration and thermal cycling, folded fin edges for improved heat dissipation, and thermal expansion cuts that extend core life. A transmission oil cooler is included, matching the original setup so there are no secondary purchases or fabrication required. Longer header tabs and multi-fit attachments round out the design, giving fleet shops and owner-operators the peace of mind that comes from a part that installs correctly the first time and performs reliably in demanding heavy-duty service. If you are sourcing by number, this unit covers Freightliner 30100R, Serck FLA002274, and NAPA NR4210509 in one direct replacement.
