11 chevy aveo over heating

I have a 2011 chevy aveo 5.Thats been giving me trouble.It started over heating on me and I dont know whyit only has 25k on it I noticed its got a small drip coming from the bottom of the tstat housing is it sapoused to do this i cant tell where its leaking from and every time I check my resavor its empty. I cant tell that it leaking any were besides the drip at the tstat housing witch has a drip. There is no coolant going in the oil or out the exhaust any idea were its going? Or whats causing it to over heat check engin light says coolant flow low I need help I replaced the t stat and o ring didnt help

well if you're constantly losing coolant, and there are no external leaks apparent, the only other place it can go is into the combustion chamber. This would explain the overheating, aalso. Have a licenced technician perform a cooling system pressure test to pinpoint the leak, internally or externally. The t-stat housing shouldn't leak, either.
