I am new to hmmwvs how can I tell what engine I have, it is non turbo 6.5, or 6.2 ?

You can identify the 6.2L engine by looking at the rear of the engine block, between the cylinder heads. Locate the oil pump/tachometer drive mount bolt on the top of the engine. If the bolt is on the left-hand side of the oil pump/tachometer drive, and there’s no turbocharger mount casting in front of the oil pump/tachometer drive, you’ve got a 6.2L engine.

And you can identify the 6.5L detuned engine by looking for the mount bolt on the right-hand side of the oil pump/tachometer drive. You’ll see the turbocharger mount casting in front of the oil pump/tachometer drive.

If the sticker is still there you can tell by looking at the drivers side valve cover. If it is a 6.2 it will say detriot diesel. If it is a 6.5 it will say General Engine Products. If the white sticker is missing you can look at the front of the engine block right where the passenger side cylinder head mounts. If it is a 6.2 it will say "6.2D" . if not it is a 6.5.
