Help!! I was told both the 3rd & 4th cylinder of my H3 Hummer need to be replaced. I was told this is the reason why my engine stays on all the time??
Thanks guys!!

Welcome to the forum Minnes . What year is your H3 ? I am guessing you are running ether the 3.5 or 3.7 L I5 engine . I would assume you have a engine light on and taking it in to a dealer or your regular Mechanic?
I have never heard of a head issue causing this . I have heard of the fan continuing to run on . We have some great Mechanics on here . I am sure they will help you out .

what do you mean by stays running? the truck wont shut off? or after you shut it off it runs on for a few seconds before it dies? if the second one happens you probably have severe carbon build up. and will have todo what they call fogging the motor. chrysler sells an amazing chemical in a spray can for such a problem. let me know if this sound like your problem, and i can give you detaled instruction on how to do it.
