Radiator
What does the exhaust look like and how does it smell?
I would drain the radiator and inspect it and smell it. Put it in a beaker, graduated cylinder, or a separator and see if there is a separation of the contents and hydrocarbon sludge in it. Once you get the present contents out and you could fill it with water, circulate it at idle, and drain it again to see what you get. Put that in a clear glass vessel (beaker, water pitcher, etc.) or separator and see if you get a strong indication of oil and water separation. Then I'd get a mechanic to look at it.
