My car overheated yesterday within 5 miles of work. I got up to 3000 rpm's and it started cutting out and then overheated. I pulled over and had smoke coming out of my hood. the coolant was hot as hell. Well once I cooled the motor off with water then I was able to get home, but every time I got up the 3000 rpm's it started again. I drove it this afternoon and it has not done it since. Does any one know what the problem could have been? Oh, i don't know if this could have had anything to do with it but I just had my car dyno tuned for max power on saturday.
