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.
Without a flywheel you couldn't even start the engine.
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 not get heat from cold water, The engine has to run long enough to get the water in the engine HOT. That is were you get heat from HOT WATER-- Coolent
Yes, you can wash your car engine with water.
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 will start but can't run for long without one. The serpitine belt drives the alternator, water pump, air conditioner and other important units to keep the engine running. Without the belt the engine will overheat very quickly and the battery will run down.
as long as you have not driven the car very long with the water pump bad and overheated the engine, it is fixable. the engine is a noninterference engine so it is not going to hurt the engine if the belt breaks.
No.
Until the engine will run without the choke being pulled.
You can run an engine in/out of a car without a transmission. Car wont move and engine wont be mounted properly. So i suggest not to run an engine without a transmission unless you know what you are doing.
This is usually a head gasket problem, meaning the engine will eventually fail without testing and/or repair.
