I am having a problem with my car. One time it overheated on me, I was able to get it home. The next day I get into my car did not even fully turn it on and it is saying "engine coolant over temp"? So I dd not think too much of it I just let it sit for a week or two and I am still getting the same message. Any suggestions? Taking it to the dealerships out of the picture.

It sounds like you have a coolant leak which will cause both issues here is a guide to help you see how to find the leak.

If everything looks okay I would try replacing the engine coolant sensor here is a guide to help you see what you are inf or when doing the job.

My Fusion was doing the same temp Gage was fine and a second later went into overheat, Mine did this 4 times in 3 days. It's at the dealership now to be repaired. They said there was a recall on the engine cooling fans and fuses. My fusion only had 12,322 miles on it.

My fusion first overheated from low amounts of coolant after it was drained from the radiator so I had added more coolant and bleed the system still overheated after that and got a P1285 code for cylinder head over temperature sensed and so the thermostat, radiator, water pump, and coolant temperature sensor have been replaced. Car does not overheat when idling only when driven and when driven it moves from normal temperature and takes a straight shot to H. The gauge does the start to overheat slowly it is a straight shot to H

Have the coolant system pressure checked for an internal leak like ahead or intake gasket.

Then have it checked to see that it is actually overheating by putting a temp guage on the return hose as it may be an electrical problem with a sender or gauge. It may not be doing what iti says.

Ford fusion sel v6 started making a rattling noise while accelerating so pulled over and shut off the car then restarted and noticed the temp gauge went all the way up when it wasn't before I'm thinking water pump but not sure.

If the car was overheating, could be low on oil or coolant. If it was the water pump, typically you will be able to see a constant drip or stream of water coming from the front of the engine. You will need to check the coolant level after it is cooled off to make sure it is full. Also check your oil level. I would not try to drive the car until you at least do these two things or you could risk ruining your engine and have to replace it. When the car is overheating do not drive it! Let me know what you find out.

Yes there could be internal engine issues. Did the engine quit running by itself or did you turn it off?

Engine light comes on and sensor says engine coolant over temperature. The sensor was changed thinking that it was a defect but that wasn't it. There's no signs of car running hot the temperature gauge needle stays in the middle and doesn't move towards hot. So what is it cause mechanics been trying to figure out for over a week now

Okay, I did the test and the head gasket is blown, I will have it repaired becasue I don't want to do the job myself. Great work you guys do here on this site. I love it :)

I wonder why the other mechanics couldn't find the problem?
