MB E230-92
Water is leaking from the drain hose connected to the lower part of the water pump. What could be the reason for this? The leak is greater when the engine is running but it is dropping a little even when engine is stopped. I have to refill the system every 3 days or so.
Where can I get a drawing of the pump?

it means the bearing is already loose, and the contact seal is broken.

it means you have to replace it ASAP.
