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.
You can not, and should not drive a car that has a bad water pump. The water pump pumps coolant through the engine. You engine will overheat and die without a functioning water pump.
You can drive for awhile without the alternator or power steering working but without the water pump working you won't get far without doing serious damage to the engine. So if that serp belt drives the water pump the answer is no.
Could cause the belt to slip and the engine to overheat.
Not very long at all. Without engine oil the engine will lock up and become unrepairable. You will have to purchase a new car of this happens.
you got water under the distributer that shorted out the electrical components
If you have a short belt that bypasses the compressor you can drive without air conditioning. If your belt is completely off, you can drive without ac, power steering, water pump and alternator for about a quarter mile before your engine overheats.
Remove all coolant from engine and do not drive car anymore!
If the water level was high enough to cover the engine and water got into the crankcase, the engine would suffer severe damage if it was to be driven. So would the transmission and the rest of the drive-train.
The water in the engine of MMW I helps cool the engine of the vehicle.
Generally, no. There are air-cooled engines that don't have a water pump, but if the car was supposed to have one, it needs it. The engine will overheat and destroy itself within minutes if it runs without a water pump.
It means that you engine is overheating. Check your water coolant level and oil levels. DO NOT continue to drive the car until the problem is resolved, an over hot engine will cease and after that happens you will need a new engine.
There will be no water pumped into your engine to cool it, then you might need a new engine.
