Yes. You can freeze the water, making it expand, or you can add cold water to a hot engine, shocking the block. You prevent freezing with antifreeze. You prevent shock by never adding water to a hot engine. If there is enough water in the engine to have the water pump provide circulation, you can add water SLOWLY, but you should really only add water to a hot engine when there is very little to add.
