07 6.0 overheated
Im posting this for my cousin , HE has a 2007 6.0 with 105K miles on it... He recently put in a new egr cooler due to it leaking or whatever they do... Then a few days later it wouldnt start so it got towed back to ford, where they put in a new HPOP . All that work totaled $5,000... Everything has been fine for about 2 months ( He drives it about 10 miles to work and back m-f)
Then this weekend he followed me up to our local shooting spot to ride the quads in the hills ( he had his quad in the bed) and there was about a 2 mile gravel road , decent grade , its about a 10 mph twisty road.. Where his AC was on and it was about 90 deg outside. When he was alomst to the top his check gauges light came on and his temp was pegged in the (HOT) .. Right when he crested the top where it flattens out , the temp stated to drop . then we stopped and let it cool down (3-4) hours .. and the overflow tank was right on the money , so no coolant was lost. When he left , he drove all the way home with AC on and no issues (aprox 70 miles) He did mention that he had the trans in Drive and it was lugging a little bit .. maybe that caused the overheat? or is it something more serious?
Is this a possible head gasket issue? Fan clutch?
Ford wants $200 for the diagnose, but chances are even if it was head gaskets , it wont do it without being under a load?
Any help would be great... Ive searched , but nothing really matches up with this problem..
