Incorrect. A faulty stuck closed thermostat would cause overheating soon enough.
And a faulty stuck open thermostat would just make it take longer to warm up to
operating temps. I have run no thermostat in the summer before
and the temp guauge still performed flawlessly.
I just cant think of how a faulty thermostat could cause the
dashboard temperature guage to read cold all the time...
Can you extrapolate on this??

Thats what I would suspect. Bad stepper motor in the cluster.
What year model is this problematic stang?
Hook up the ol MSD DashHawk and see if the can buss is reporting the
coolant temps to the cluster. That would find the problem.
Have you tried the troubleshooting charts for a faulty temp guauge
in the WorkShop Manual?
