Can be a defective temperature sending unit. If you just chance the coolant can be air trapped in the cooling system. You would need to bleed all air from the system. Can also be a defective gauge, but highly unlikely.
What could cause the temperature gauge on 1965 mustang 289 to read cold all the time?
I had the same problem with my 1970 mustang. First take the wire off of the Temperature sending unit (usually on the front of the block) and ground out the wire and see if the gauge goes up on the dash. if so it is just a temperature sending unit. They cost about 7 dollars.

What is a double temperature switch BMW?
It has 2 independent sensors in it, one goes to the cluster for the coolant temp gauge. The other goes to the DME for controlling the fuel mix, engine timing, cam timing, as the enging goes from cold to operating temp. It effects performance, MPG, and emissions.
