At below-freezing temperatures, pure water freezes at 0 °C and expands, which can crack pipes, the radiator or the engine block itself. That is why you must use a coolant that contains an antifreeze additive suitable for the lowest temperature at which you expect to drive. Replacing the coolant with ordinary water is a mistake, because water freezes easily. And thinking that the outside cold does not affect the engine fluids is also a mistake, since frost can seriously damage the engine if the coolant has no antifreeze protection.
