Mine had the same issue, never found a drop of coolant anywhere, but every so often you could smell coolant. Mine turned out to be one of the heater hoses on the right rear of the engine bay rubbing against the valve cover. Rubbed right through the sheathing causing hole in the line. New hose was $27 and has been re-routed off the valve cover. Hope this helps.
