Coolant leak in the freeze plug

[ethan]

There is a coolant leak in the freeze plug of my Mercedes. Can anyone tell me if I can fix it myself? How?

Freeze plug leaking is really dangerous. You can fix it temporarily by putting the sealer, but the permanent solution is replacement.

Yeah, I agree, but this is a really complicated process and they will probably have to pull the engine out to check what the problem is. So, be prepared for that and visit a repair shop with good reputation.
