Massive cooling water loss Om 2.5 td

After the engine cooled down somewhat, I replenished it and found that the coolant on the engine block flows off at the bottom right (if I stand in front of it). Can’t see exactly where the water comes out, however, think that I’ve turned out the spot on some hoses. Now the question: Can this also have left the coolant circuit of the engine block? Then I can probably say goodbye to the omi… ?? A u nknower is grateful for any answer.. !
