Today my wife's Town and Country started having a Anti-Freeze smell...I looked around the engine bay and checked under the car but I do not see any leaks. When the car is driven, there is no noticeable drop in coolant and the temp gauge is just below the middle after being driven. Any ideas?

 

Is the carpet wet at the front passenger's feet? The heater core leaking coolant is the usual culprit in that case.
