Where is engine number located on Hummer H2?

The engine number on a Hummer H2 is located on the driver's side (left) of the engine block, usually near the front. However, it's not always easily visible and might be partially obscured by other components. You may need a flashlight and possibly even have to move some smaller parts to see it clearly. A repair manual specific to your Hummer H2's year and engine type will provide the most precise location.
