Common problem with some of them. I have forgotten the name but a company in Utah made a Induction Overhaul Kit, nice aftermarket item to fix it.
Maybe Larry Barnhart will chime in soon as I believe he has one.
I do have the air system but mine was from Arizona by killer bee. I have never had an overheating issue. I also have the scanguage11 that shows the correct water temp. I do have one issue for the last 3 trips south when towing at higher elevation going up mountains. The intake air will spike and the fan will come on at a low speed but full blast at times. engine temp will be 197 so now I wonder if an air sensor or etc is making the intake air rise in temp. this shows on the scan guage. Not really an issue but is a new problem maybe. I might look into it this summer. Never had a cel light come on to really give you any help. My truck has been maintained to extreme overkill.
