This is a 2.7 liter, don't bother answering if your not familiar with this particular engine because the cooling system is the most crazy thing ever thought up, and your answer will more then likely be wrong .
Its leaking near the thermostat housing but not from it. There is a small unthreaded hole about an eighth of an inch from the lower most housing bolt. Its pouring water out of this thing as fast as I put it in. I just went through all the pain and work of replacing the thermostat and gasket to find out its actually coming from this hole. Maybe if you know what it is you could be kind enough to elaborate on the purpose of this hole too?
