Question about 2006 Hummer H3

1 Answer

My 2006 hummer h3 has blown a head gasket twice. the first time was at 36000 miles and now at 68000 miles. Dealer is telling me this is not a recall and nothing I caused or could have done to prevent this from happening. They can not tell me why it blew and I think its going to blow again since they can not determine what caused it. Have you guys heard of this and what recommendations do you offer???

How do you load the cam actuator after changing the head gasket on a 2006 Hummer H3?


two ways: cranking the engine by turning the crank pulley bolt. Best done with valve cover off to verify full engine oil prime. The other economical way is by disabling the ignition and fuel pump (fuse removal) and cranking engine for 5 seconds, three times each.

What would cause a H3 Hummer to burn oil and give off smell. Temperature gauge rises as well.


One thing that could do all of that is a blown head gasket. That would allow the oil to mix with the coolant and the coolant to mix with the engine oil. Have to get it fixed right away or the engine will be trash.

I have a Hummer H3. I hear Noise from wheels while turning & doesn't stop. Also I hear a grinding noise when I hit the brakes. Dealer had to resurface rotors. Problem started at 15000 miles. Took it...


Ranjit,

I have the same problem with my 2008 Hummer H3. I had the front and rear rotors resurfaced. I am now thinking of getting the rotors replaced with bigger more durable rotors. Solution about the sticking brake caliper sounds about right if you hear a grinding noise as you drive without even touching the brake pedal.

A bad or sticking brake caliper is the likely cause, and the dealer knows this. They are slow-rolling you until your warranty expires. Then I bet they find it right away! Have a reputable brake shop inspect it to confirm.

1) Loosing antifreeze 2) tranny shifts funny


if your exhaust is loose it causes car to run hotter, also if you are running the wrong gas in it, so check on that.HOWEVER your thermostat and water pump are the main suspects here. If you are losing antifreeze, it may be a blown head gasket which is No good, this is caused by your 2 main suspects here. Check oil and tranny fluid levels. you cant keep driving a car thats having problems, .. thats how you get bigger problems like blown head gaskets. TRUST ME. as a teen i owned 3 differnt cars, and had to chang head gasket on every one of them because of POOR MAINTENACE. check these things, and get back to me
