What is wrong with my car won't hold water?

If your car will not hold water you should first check your radiator for holes and leaks. This should be done with the engine turned off. If you do not find any leaks coming from the radiator and the water stays inside, turn on your vehicle and let it idle. If you notice water leaking from the vehicle while it is running, then your water pump is bad and will need to be replaced.
