Hello colleagues I replaced the engine water pump a year ago with a new original mercedes because it had run... Five months ago, I was opening The engine for changing the timing chains And I noticed that the water pump has started to Leak again... I want to ask if there may be any problem in the car that leads to the leak of the water pump, because it is not normal for a year a brand new pump to defect ? Thank you

Is it leaking from the gasket or the pump itself?
Maybe the gasket was not installed correctly. Is the pump remanufactured? Its not uncommon for remanufactured parts to go bad in a short time.

No, it's brand new! It's not recycled. Everything is set properly
