I have a '97 C280 inline 6 MB, I have had to put antifreeze in for the past few weeks now I found the leak. Its gotten worst so I stop driving it for the time being

, Standing in front of the hood on the right hand side of the motor, its leaking from under the????????


Not for sure if its the water pump or thremosacts housing. Can any one help me with this problem. Kinda want a little light on the issue before going in.
