#11BenzAZE350 thank you PSDCAMPERVAN. I remembered that about 8 months ago, my mechanic replaced the upper radiator hose. I don't think that's where its leaking from, but suspicious. So this last weekend I put some Blue Devil Stop Leak in the radiator. I'm going to check it this weekend to see if the leak has ceased.

PSDCamperVan There is a peculiar o-ring between thermostat housing & coolant hose with a quick-disconnect type fitting that had a slight cut in it on mine which would cause it to leak but only once up to operating temperature & pressure so tracking it down required observing engine once warmed up to see it dripping.

coolant leak under intake

2011 E350 Bluetec -after getting my oil changed today, the mechanic took me under the engine to witness a slow coolant leaking like stalactites under what he said was the intake valve/manifold. I don't remember. Anyway, has anyone ever had this before, and if so, what's a girl to do?
