how do i find the motor size in the vin for a 2007

 

I am not sure about that but look on the side of the valve cover and it will have sticker that will tell you the size of the engine.

Or get the vin number off of the engine and call cummins. they can tell you all about your engine.

There is a seperate vin on the engine and the one for the Vehicle.

 

write your vehicle vin # down and call your local dealership on monday, they'll tell you what it is. Or like the guy above me said, call Cummins.
