Water Drains always from coolant reservoir while the car is stationary. I refill water every day in the coolant reservoir.

The car temperature is fine, it does not overheat. While driving the water level is always fine.

You only notice this drain the following day during routine check.

Start with a cooling system pressure test, this will help locate any external coolant leaks.

There is a special tool for this, your local mechanic can do the test, it will take a min or two only to check.
