Duramax VIN Engine Identification

Identifying Duramax Engine Version Using The VIN Number

For some model years, it may be difficult to tell which Duramax your truck is equipped with. Often times, the new version of the Duramax was released in the middle of or at the end of a model year, so the year of your truck alone does not tell you which version you have. Use the table below to identify which Duramax engine your truck has based on the 8th digit of the vehicle identification number (VIN). This is the truck's VIN number, not the engine's identification/serial number. The VIN number can always be found on your vehicle's title or registration card. It is important to know which engine you have since not all components are interchangeable between the various versions of Duramax engines.
