I know where it's located on a older small block GM V8, and it's easy enough to change out on one of those... if it's not being stubborn and hard to turn.

They used to put the sensor on the lower half of the block near the freeze plugs. Under the intake sounds like a real PIA place to put it.

Did you inhale too much toxic fumes?

He said a 2003 hummer h2 with 50,000 miles..... not an H3. It's in the right forum.

Yes the KS is located underneath the intake and the intake would have to be removed, I think there are 2 of them on the 6.0L and if you are doing one, you might as well go ahead and do both.

Really not much reason why anyone slightly mechanically inclined couldn't do the job.
