    Not sure if the E makes a difference but look on left side below the intake and above the starter

    What’s it installed in Pedro.? If it’s a Cat do you have a S/N for the machine.?

    If you have the truck VIN the dealer can tell you what it was born with, doesn’t mean it hasn’t been changed. What year is it? In the states that would at least give me a good guess on the prefix.

    Sorry Pedro, only saw it was in the truck forum after I posted. Try the LH side of engine close to the flywheel housing. If it has a LH-side starter motor the plate might even be partially obscured behind the starter.
