Heat will flow from the coolant into the air.
Yes, both the high and low pressures of a vehicle will be lower than that of an a/c system in a building.........
My engine coolant is a 50 / 50 mix of antifreeze and distilled water so adding water will just dilute the mixture more and weaken the antifreeze so the coolant mixture will freeze at a warmer temperature and it will reduce the corrosion protection if there is not at least 40 % antifreeze
The coolant will not protect the cooling system against corrosion.
When water/coolant freezes it expands with great force. It takes lower temperature to freeze coolant, this is why it is called antifreeze. When it expands it causes a great deal of damage to hoses and the radiator. If it gets cold enough even the engine may warp, but this is rare.
It will be a building?
Nothing all overfloo is extra coolant latter the car will be are on the normal level of coolant after a couple miles.of drive.
Nothing will happen if you drain the cooling system and replace the coolant.
if you take it out then the coolant would continue going through the radiator and cooling the coolant, this would never let your engine get up to operating temperatures, the thermostat opens and closes depending on the temperature of the engine. leave it alone its there for a reason
I don't know the reaction it would have on the coolant but I would advise you to flush out your system immediately and put in fresh coolant.
It is possible that the gasket could leak between cylinders. The overheating and coolant loss would happen if the gasket was failing around the coolant passages.
that has happen to me if you got a car wash lately then it must off happen usally the wires are exposed just let it all dry
DAS Building bombing happened in 1989.
