It can. You should leave the engine running while you add water to the radiator. If you add water with the engine turned off, but while the engine is overheated, you might damage the engine or the radiator.

Car steam usually is not a good sign. The main reason for a car to emit steam is normally that is has overheated causing water or other fluids to become too hot.
To fix an overheated car, first, safely pull over and turn off the engine to prevent further damage. Allow the engine to cool down for at least 30 minutes, then check the coolant levels; if low, add a mixture of coolant and water. Inspect for leaks, damaged hoses, or a faulty radiator, and ensure the thermostat and water pump are functioning properly. If the issue persists, it's advisable to seek professional assistance to diagnose and repair any underlying problems.
Water in combustion chamber-common sign of bad head gasket especially if recently overheated. Oil will probably have water present in it and easily apparent.
Not a good idea to add water. You should add an engine coolant available from any auto parts store. You should never remove the radiator cap when engine is hot! Wait until the engine has cooled down then remove cap. Fill radiator with engine coolant, replace cap and then refill coolant reservoir. That procedure will get you to a garage where they will find out why it overheated in the first place.

If you can't see where its coming from, it may be a cracked head, or a bas headgasket. Also, when you add water to the coolant tank, it doesn't immediately go into the radiator. After the car sits a while, the radiator starts to cool, creating a vacuum. Water/coolant is then pulled into the radiator from the coolant tank.
