I have a 06 H3 and she has 67,000 on her and I seen that at a stop she was not running right. It sounded as if she about to fall on her face. So i took that K&N out and cleaned it. Still same Issue. I scanned the ecu and nothing then I said what the hell I will put new plugs in her and when I got to CYL 3 there was coolant in there. So my question is the head or head gasket.

thanks

 

It can be either. most likely head. you should be at the hummer dealer not hummer forums bro. i cant see your engine unfortunately

 

I believe it falls in the group for the Head issue. like Panamera said, i would be enroute to the dealership with your H3.

 

yea... what stinks though is that it looks like you're out of warranty unless you got an extended... have no clue how much $$ it is to fix but glad I didn't have to give up any for mine.

 

I would cause a serious stink if they try to make you pay for the repair......It is a well known problem. Make a big enough stink and they could lower the price or make it free.

 

its a manufacturer's fault. If you pay a cent you are basically donating your money.

if your dealer is half decent they wont even ask for money. but you never know with people these days...

 

so gm knows about a head issue with the 06 H3's?

 

2wheelmonster,
Welcome aboard. Do a search. Just type in 'HEAD', and have your 6 pack on the table. You'll be there awhile.

UPDATE-

Well the dealer called me and making things sound as if there were doing me a favor and all () telling me yes we did a leak down and your head is cracked ,but they can fix it. I was like for real you can? Then he hit with a $500 deductible. Witch i will gladly pay and they also gave another 60,000 warranty. So for the most part things went real well ! I will have my baby back next week and she will be good as new.

The surprise of it all it was painless for the most part. I know that alot of other hummer owners have had to go to hell and back for get work done but this time for me things went great.

I want to thank all you guys for all your help. I will keep everyone updated things.

Thanks to all.

 

The "Head issue" for the 06s has nothing to do with cracks or blown gaskets. If you have coolant in a cylinder, it was NOT the head issue that GM corrected in all the atlas motors built prior to 03/31/06.

The head issue involved valve seat failure. The fix was to harden valve guides and seats (increase the hardness) in all the atlas motors after 03/31/06.

Many other problems can mimick the same symptoms, and you won't get anywhere getting angry about unrelated problems.

At any rate, glad to hear things are working out.
