Mercedes Repair Questions? Ask a Mechanic for Answers ASAP
Hi, my name is***** you upload some photos of what you are seeing?
It's hard to determine from your description where the leak is. It sounds to me as though the leak may be coming from a drain hole in the block. If that is the case I would suspect a leak from one of the heater hoses at the back of the engine. I think the leak may be pooling in the valley of the block and draining out. The best thing to do is pressure test the cooling system. The leak may be more evident under pressure.
If you can send me a picture it would help.
