Might be a bad thermostat. I'd also might say a bad gauge as Foxes are known for faulty temp gauges (at least mine were).
I'd check the thermostat first, and check for leaks around the water pump.

Your gauge was fluctuating because of the low coolant....the sending unit would rise when there was only hot air/steam and then fall when a burst of coolant hit it. These cars do not use coolant normally so you have a problem....especially having to add 1/2 gallon! Check out your water pump...when the bearing starts to wear it will leak out of the little seep hole under the snout....but only when it cools down so it won't leak all the time and usually not when you are around. Very common problem with the water pumps when they go bad.

This happened to me in 2 different Stangs.. When the guage would read HOT I would pull over and check the vitals. Everything was ok and definately not running hot. The stock guages do this all the time in older stangs.. I changed to a auto meter guage and never looked back.
