Newbie here guys. I have an '07 Mustang GT that is overheating. On cool or rainy days and in the mornings, it does fine. Later on in the day, after it gets hot out, it will overheat. It does fine when I first crank it, when the engine is cool, and the fan runs. However, once the engine reaches a certain temp, it starts blowing warm/hot air out the vents, and the temp climbs very rapidly. At this point, the fan is no longer running. It seems the fan is not working properly when it should be on high speed. So far, I've replaced the thermostat and fan assembly, have had the radiator cleaned and flushed, and have checked the relay. None of this has fixed the problem. I'm at a loss! Can anyone help?
