I had the same problem with my truck. replaced thermestat, cap, fan clutch. flushed out sytem but it wouldnt solve the problem. What the problem was, was the water pump. I never even bothered with it cuz it didnt leak out the blow hole. so i figured it was good. but when i took it off i could see that it wasnt working right. the water damage from it not working was pretty bad. but once i replaced it, it stopped over heating. the most it gets to is about 212 which is a bit past half way. and to replace it is very easy i wouldnt take it to a mechanic save the money
