Hey there , I have a 05 6.0 , 174,000 miles has the 6.0 update done to it, the other day I was heading up hunting the first big grade I hit , just loaded down with camping equipment , for 4 guys and full tank of fuel, I started up the grade and about 3/4 of the way up I notice my temperature climb about 3/4 of the way on the gauge and usually driving around town and freeway it's about little under the middle, I did have the ac full blast ( outside temp was 100 degree) the fans kicked on and the temp just stood there, after the climb and it leveled out the temp kicked down pretty quick , is that normal? I'm getting a scangauge soon , I also done a coolant flush I say about 100 miles or so if that prior , the rest of the drive had climbs but not to bad and the temp never did budge after that. I did also had to add about half a gallon of coolant when we got to our camping spot, from the grade to the camping spot was about an hour of mountain driving . Possible air pocket?
Thanks sorry if I'm so scramble about my information
