I went about two miles this morning and the gage went up to the three quarter mark . I haven't let it go to red hot or irt hasn't gone that far yet . I did what you said yesterday and after I was done I let the car idle for about a half an hour and then took it for a eight mile drive and it was ok . After it went to the high mark this moring I repeated what I did yesterday. It was fine after that I took it on another eight mile drive and it acted normal. I let it set for about three hours ,tok it for a ride and the overheating started again.
