If you smell antifreeze, there must be a leak somewhere. Have the cooling system pressure tested.
( NO ) with the engine cool
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.
No , it's best to add coolant when the engine is cold
White smoke is antifreeze, intake or headgasket.
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.
It's supposed to do that.
Yes it can, as long as the engine is running. Be careful when taking the radiator cap off thou, cause its under pressure.
The smell of antifreeze is very strong and distinct, it does not take much of a leak to smell it. The radiator could still be full and have a small leak. I would check for antifreeze dripping onto the exhaust or on the engine block because when it is hot the smell is much more noticeable from the fumes.
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.
No. It will keep running until overheated to the point of a ruined engine.
