Hummer H3 For the Hummer driver who wants the rugged look and off road capabilities of the Hummer, but in a smaller size and with a more fuel economy friendly engine.

Is this a normal start?

Sounds like a worn pulley bearing, remove serpentine belt and restart/recheck(not too long don't overheat). Noise go away?

If you end up replacing a pulley, replace the belt too. Inspect it thoroughly while you have it removed if you decide to reuse it.
