YW Sdtrock9. If you want to know more about these engines and their problems, go to on a school bus forum. They put a lot of these engines in school busses. They gave fleets fits. The cooolers would break and leak into the last cylinder and would hydro the cylinder and bend rods. This happened a lot.
Or you can Google Max Force engine problems and you can have reading for weeks and weeks.
Super funny video of a guy talking about a MaxxForce 13 Yes I know it's not the 7 but it's still funny and is pretty much the same with the 7 for different reasons. This dude is great!
