Your car was running hot and it overheated you pulled it over and got towed to the garage What are the chances your engine is blown only could smell antifreeze?

If you stopped as soon as it overheated, you probably have no damage, unless the head gasket has blown. This would require replacing the head gasket and possibly resurfacing or replacing the head. Depends on why the gasket blew, if it indeed is blown. You may have nothing more than a stuck thermostat, bad water pump, low coolant level, clogged radiator, or a non functioning fan. 29s here, a mechanic once told me that the 2.5 motor could go through hell was gasoline panties on. just dont over fill or deprive it of oil.

Your car shouldn't "burn" antifreeze. If it actually is "burning" antifreeze then chances are you have a blown/leaking head gasket or possibly a cracked engine block which allows antifreeze to enter the combustion chambers. If your antifreeze is just disappearing then it is probably leaking out from somewhere. Possible leak areas to check out would be the radiator hoses, heater hoses, radiator, water pump, and the heater core. Most of the time if the heater core is leaking you'll be able to smell the antifreeze inside the car while the engine is running and the heater is on.

What cause the BMW run hot off and on what capfuls next the problem

Your engine should be cold ( to be on the safe side) when adding antifreeze/coolant. i let the car sit overnight and then add it.

Many people associate the smell of antifreeze with an overheated engine. The only reason we do that is because we certainly smell antifreeze when the engine is overheated and blowing out antifreeze, but if there is just a slow leak of antifreeze and we smell that, we MIGHT be able to convince ourselves that the engine is overheated. Check for coolant leaks around the engine, radiator and heater hoses. After cooling down and drying out, antifreeze will leave a blue/green powdery subastance. Good luck finding the problem. question did not ask why he was smelling antifreeze if you car smells hot, then obviously it is hot' check for correct coolant level. if coolant is correct the thermostat may be faulty , your water pump may be faulty, or you need a new fan belt so armed with this i would first check thermostat, it is not opening to allow proper amount of coolant to circulate. but also not showing overheating on dash gauge have it checked before you damage your engine

No , it's best to add coolant when the engine is cold

Running it without a freeze plug it will run but can and will cause permenant damage to the engine to to the amount of antifreeze you will lose Running it without a freeze plug it will run but can and will cause permenant damage to the engine to to the amount of antifreeze you will lose

antifreeze does two things. It keeps the water in the radiator from freezing in the winter, and helps prevent if from boiling over and evaporating in the summer. You can run your vehicle with water alone in moderate temperatures and it will do the job. But, if you mean by "running out of antifreeze" you mean there is no liquid in the radiator, then yes, your vehicle can overheat and ruin the engine.

because it's been overheated and damaged.

If the engine was severely overheated, yes that can cause engine failure.If the engine was severely overheated, yes that can cause engine failure.

Engine may seize if overheated to that extreme

if there is engine oil in the antifreeze generally indicates a cracked head on the engine

Yes it can, as long as the engine is running. Be careful when taking the radiator cap off thou, cause its under pressure.

Overheated but multiple codes could have come up and more than one possible cayuse. Read trouble codes and start there.

You either ran out of gas or your engine overheated.

if you find puddles of antifreeze around the water pump or while the engine is running,if you feel spits coming off the belt while its running.

Antifreeze does 2 things. First it protects your engine when the outside temperature is below freezing and the vehicle is not running. If the coolant freezes it could crack your engine block requiring a new engine. Caution: 100% antifreeze will also freeze up if it gets too cold. For best results you have to mix antifreeze and water. Check the antifreeze container for correct mixture. Antifreeze also has other things in it that keeps the water pump in good shape, prevents corrosion of the the radiator and helps transfer heat out of the engine. You need it even in hot weather.

Engine overheated. Possible causes are: Thermostat stuck closed. Low of coolant. Defective radiator cap. Clogged radiator. Defective Water Pump.

It can. You should leave the engine running while you add water to the radiator. If you add water with the engine turned off, but while the engine is overheated, you might damage the engine or the radiator.

Is there white smoke coming out of your exhaust pipe , even when the engine is warmed up? That's the most obvious sign that coolant is getting into an engine cylinder from a bad head gasket , a warped or cracked head
