Your engine can lock up if there's no water in the system.
yes the water in the coolant will dissolve the clutch material inside the transmission and then the rebuild will cost you more money then it would to fix it now before any additional damage is done.
Overheating and leaking coolant is a sign of a bad water pump. There is a hole on the bottom of water pumps that allows coolant to leak when they are going out. This is to warn you it is going out so you replace it before major damage is done.
No, but if the failure causes a fire or water damage, then the water and fire damage will be covered.
No, they are not. Droids are extremely sensitive to water damage, because of their screen, and if they get water damage, they're as good as done.
It's alright as long as the temperature of the air outside does not fall below freezing. Most cars have a 50/50 mix of antifreeze/water anyways. If the temperature does fall below freezing and all you have in the coolant system is water, it will cause a lot of damage to the engine and coolant system (it will freeze and expand, tearing hoses and could potentially damage internal components of your engine, such as the head gasket).
Assuming you mean coolant (not water), you probably have a bad head gasket or a cracked head.
The longer you wait the more damage will be done to the engine due to the coolant mixing with the oil.
Yes, you can. But if you leave in cold area you will have to replace with proper coolant closer to winter. Otherwise it will damage not only your radiator but also the engine.
It has a much lower freezing point than water. if the coolant freezes it expands cauing pressure damage or even leaks. It also contains anti corrosion chemicals to prevent rust inside the engine.
your radiator has internally failed. it needs to be changed immediatly before irreversible damage is done to the transmission. flush your transmission and coolant several times.
If your car is leaking coolant get it fixed and put in the recomended coolant for your car. You should locate that info in the manual, also putting water in the winter is a bad idea since the water could freeze causing engine damage. I supposed you might be able to run it for a while in the summer with just water but get the leak fixed and put in the recomended antifreeze/coolant
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.
