How many miles in between spark plug change on 06 h3 hummer?

why change if there's nothing wrong with it. as long as you don't get a hard time starting it and the engine runs fine then there's no need to change. Like what we are always say " why fix if it's not broken".

What is draining the battery of my H3 Hummer?

it may not be a drain on the battery the alternator may not be charging at the correct rate , this will not always bring on the red charge light if it is just below the range , do you drive at night , use the A/C ,etc things like this can drain the battery whilst driving and not getting re-charged by the alternator.If the charge rate is ok then disconnect the earth cable and put a test light between the earth terminal on the battery and the earth cable , if it lights up then there is a drain , check any interior light that may be on all the time , glove box or under hood are usually overlooked , if no lights found then remove the fuses one by one until the light goes out , that will tell you what circuit the drain is from , then you know where to investigate , loose connection , worn wire etc keep me posted if you wish

Where is the thermostat on a 06 hummer H3 is it on the upper hose or lower hose

The on the left side of the engine under the back of the alternator. You have to go through the wheel well to get to it. Stupid place to put it. It's not easy to get to.

My 2006 H3 will not come out of 4 wheel drive?

Hummers are 4WD all the time, you can never take it out of 4WD. Now, you can select between locked 4WD HIGH and locked 4WD LOW. Those are switched by putting the vehicle in Neutral, and pushing the button the dash, waiting till the correct indicator light illuminates and then putting the truck in drive. Based on the above info, what exactly kind of 4WD drive problem are you having?
