First post, I have a 2007 Suburban w/ the 6.0 ... its my wife's daily driver so I see it when it needs gas and has a problem ... when it is started in the morning it will climb in temperature to 235 and sit pretty constant, if you drive it to the grocery store and sit in it it will idle at 235-245 ... if you run down the hyw at 60mph it will cool to 210 ... if you drive around town in stop and go traffic it will range from 225-240 ... I'm taking it in tomorrow to see about having the thermostat replaced (does that sound like the place to start)?

Thanks,
Casey

My work truck is a 2004 1 ton truck with the 6.0 liter it runs at 210 allday long from 10 minutes after starting it in the cold mornings to when its 115 in the summer that thing has never been over 210. I would have it checked out before it gets ugly.
