Mystery loss of coolant without leaks

Mystery loss of coolant without leaks is what I have on my 2004 Town Car.
I checked the oil and it appears there is no coolant in it.
No sweet smells of coolant through the heater or defroster,or wet floor.
No leaks underneath.
It looses about 10 oz of coolant every 500 miles.
Any ideas would be great.
Thanks.

Before I replaced the manifold on my '97 TC, it leaked about that amount but never dripped down since it was mostly evaporating off of the top of the engine block underneath the manifold.
This went on for a couple of months before I located the problem by smell with the hood open immediately after driving the car. Eventually I located thedrip point where I could see coolant leaking, but it only leaked during warm-up, beginning a few minutes after starting the car, and stopped leaking a few minutes later.

Is you cooling fan on the radiator working OK?

Temp always in the middle or does it run high sometimes?

This video show a TC that apparently was running a little hot and it pumped out coolant through the overflow.
