Overheating caused of overheating

There are several reasons why your 2014 Ford Fusion may not start after overheating. Here are a few possible explanations:

1. Engine damage: If the engine overheated severely, it could have caused damage to the internal components of the engine, such as the pistons, cylinder walls, or bearings. This damage could prevent the engine from starting or running properly.
2. Blown head gasket: Overheating can cause the head gasket to fail, which can result in a loss of compression and prevent the engine from starting.
3. Electrical damage: Overheating can damage the electrical components of the engine, such as the starter, alternator, or battery. This damage could prevent the engine from starting or cause it to start but then stall.
4. Fuel delivery issues: Overheating can also cause problems with the fuel system, such as clogged fuel lines or a faulty fuel pump, which can prevent the engine from getting the fuel it needs to start and run.

If your car is not starting after overheating, it's important to have it inspected by a qualified mechanic to determine the root cause of the problem. They can diagnose the issue and provide a solution to get your car running again.

You're overheating (bubbling) and low on coolant (no heat). You might have a leak causing the coolant to run low and that can cause the overheating, or possibly the cooling fans not turning on which can also cause overheating. Either way, you should get it looked at asap before you cause damage to head gaskets or something else.

Oil in the coolant caused by blown head gasket or cracked head. This will also cause overheating. :o(

many things can cause an engine to over heat
Look for any collasped water coolant hose. That will cause overheating'
If the inside of the engines oil cap looks to have a creamy filling in it that will be from coolant mixing with the engine oil. Head gasket leak and can cause overheating
A clogged up heater core or radiator can cause overheating
A loose or worn seal on the radiator fill cap can cause overheating as well

The car overheated and something caused the overheating. Bad thermostat, low coolant level due to a leak or busted radiator hose, inoperative cooling fan, or a bad water pump. Lots of things can cause an overheating condition and I am not really sure that any blame can or should be assessed to anyone regarding what caused the overheating....something caused it and I would be hesitant to blame the driver. I doubt that the person did anything devious like drain the coolant out. However, poor judgement was used in continuing to drive the vehicle after it overheated. This can cause major problems like a blown head gasket or even a completely blown engine. Maybe the lady panicked or was unaware of the damage that it could cause to keep driving. I suspect that it wasn't something malicious (she probably feels bad enough, already), but just a simple error in judgement. I would probably give her the benefit of the doubt and explain (calmly), the mistake that she made and why it was a mistake. She didn't cause the original problem, she just handled it badly. I would check the condition of the vehicle out and go from there. What's done is done.
Start by trying to find out what caused the overheating and if it caused any permanent engine damage. Some of the things that I mentioned earlier would be a good start, or you could have a certified auto tech take a look at it. It was really nice of you to lend the use of your car to someone. I am really sorry for the trouble you are having and I hope this helped. Best wishes.
