I bought the 2011 GT used about 3 months ago with 15k miles on it, so far it has overheated 3 times, the first time the Ford dealer put a water pump in it under warranty, the warranty expired and it overheated on two more occasions, Ford can't figure out whats wrong with it. The first time it overheated was at idle, the second time was coasting, and the third was on the highway. My thought is its the thermostat, but Ford checked and said it was fine. Has anyone else had a similar issue? Car has 19k on it now

Replace the thermostat. Thats your best bet, sounds alot like it

This will sound dumb but might be worth a try. I had a similar issue when I owned a 300zx. I changed everything in the cooling system and kept overheating. A guy at a bar overheard me talking about the issue and said to change my radiator cap. Lol, it worked and my car was a champ after that.

That's the first thing I always check when there's over heating issues that aren't obvious. A weak radiator cap lets the pressure in the system drop, which lowers the boiling point of the coolant.

Mr. V

Lol, me too. Now. Maybe you were the guy in the bar that saved my cars life. I was thinking of getting rid of it at that point.

Could have been, I've spent a hell of a lot of time in bars through the years.

Would the thermostat cause it to overheat intermittently? Each time has been about a month apart.

Could be the temperature sensor that tells 'when' the electric radiator cooling fans should kick on. I would change the radiator cap and thermostat first.

Sounds like the thermostat should be changed/ the temperature sensor, perhaps?

Ok, replaced the thermostat Wednesday. But like I said earlier, each time was about a month apart, so I guess I'll be back if it does it again. Thank You

are you sure the car wasnt tuned, and might require higher octane gas? ever hear it pinging at all?

The car is overheating again, water pump, thermostat, and fan assembly have been replaced with OEM parts. Only seems to do it when it's hot out and the A/C is on and vehicle is not moving. Once I get moving it cools down. Any ideas?

Thermistor for the cooling fan or fan is stopping prematurely

Radiator cap.
