In addition to that, you can only run Ultra Low Sulphur Diesel in those engines. If you're one of these geniuses who puts diesel fuel in the DEF tank, you'll really be paying out the nose, because, on top of the DEF tank and all lines, the entire DEF dosing unit and SCR will have to be replaced. Then you'll have to get the DEF tank cleaned (or even replaced), get the DEF doser serviced, get all DEF lines replaced. Take a wizz in the DEF tank, and the sensors will detect impurities in the DEF, and derate the engine. Check with the dealer as far as what your service intervals for those are going to be, because the stuff I work on is a bit different from what you're looking at, and generally turns lower RPMs running down the road.ĭO NOT get the idea to take a leak into the DEF tank - people read about DEF being composed of urea, and think they can pull that one off, not realizing that the urea is synthetic and of an extremely high purity. Additionally, I believe the ISB also has a crank case filter, the way the ISL, ISM, and ISX do. In addition to your regular services (oil changes, etc.), the aftertreatment system comes with some other regularly serviced items you'll need to be diligent about - the dosing injector, DPF cleanings, DEF doser, and DEF filter, namely. These systems are generally more reliable than the 2008 - 2010 models, which just had the DPF, but it's also more which can go wrong, as well. The model years you specified are going to be CARB and EPA2010 compliant, and will have an aftertreatment system consisting of a Diesel Particulate Filter (DPF), Diesel Exhaust Fluid (DEF) doser, and Selective Catalytic Reducer (SCR). The 6.7 ISB, I haven't really dealt with too much, but I'm very familiar with it's big brothers, and the build is more the same, albeit on the different scale.
Not a fan of Dodge, but the model years you're talking about are more recent than the most recent model year of theirs I had experience with (the 2009 Sterling Bullet, which was a rebadged Ram 5500). we're talking diesel engines here, not porno films.
