You have a coolant leak.You have a coolant leak.
First of all you shouldn't be using water, you should be using engine coolant. And to answer your question, your engine will over heat and you will not be able to drive. You can do damage to your cars radiator running with no coolant.
Yes, If to much leaks out this will cause the engine to over heat, smoke and or stall hence the name engine COOLant :)
Possibly one of the outlets is broken therefore leaking all over your engine.
If you mean engine coolant is getting into the car, the heater core is leaking coolant causing the coolant level to drop and that causes the engine to over heat.
All engine coolant is roughly the same but some are advertised for performance cars.
If the coolant reservoir can not maintain the proper level of coolant, it is possible the engine could over heat when the level drops.
Fill your coolant reservoir and the light should turn off. Do it soon or your engine may over heat.
With the freeze plug out it will be impossible to keep water and coolant in the engine as it will all leak out through the freeze plug hole. The engine will over heat and self destruct after a while.
Ok, 50/50 is pretty much the norm. Coolant is not what keeps your engine cool, the water is. The coolant is what keeps the water from freezing in cold weather as well as from causing corosion to your engine.
No it is all basicaly the same.
The water and coolant is put in the coolant reservoir for the location of this refer to the owners manual. It is best to do this when the engine is cold otherwise you run the risk of getting boiling water all over you. the mixture of coolant to water should be about 50/50.
