Keep your Freightliner's diesel exhaust fluid system sealed and functioning properly with the Motorad DEF104 filler cap. Built to fit the DEF filler neck with a secure twist-lock design, this cap helps prevent DEF from leaking or spilling, protecting your truck's emissions system and the surrounding environment from unwanted fluid loss. A worn, cracked, or missing DEF cap can allow contamination or evaporation issues that affect emissions performance, so replacing it restores proper operation of the DEF system. The DEF104 covers a wide range of Freightliner medium- and heavy-duty applications, including M2 106, M2 112, Cascadia, Coronado, and more, spanning 2010-2015 model years. Sized with a 58.17mm thread diameter and finished in blue for easy identification, this cap is a straightforward, direct-fit replacement for fleet and owner-operator maintenance. Keep your DEF system sealed and compliant with a dependable Motorad replacement cap.
