It should be right beside the thermostat housing unit.
The temp sending unit for the temp gauge is located on the drivers side of the engine between cylinders 3 and 5 spark plugs.
The temp sending unit on the engine could be unplugged or faulty.
Could be the temp sending unit located on the driver's side head, between the #1 and # 3 spark plug.
Below the water neck on the front of the intake.

bad relay or temp sending unit

The engine temp gauge is in the instrument cluster and the sending unit for the temperature gauge is in the intake manifold just to the left of the thermostat housing when you are looking from the front of the Explorer ( the larger sending unit to the right of the thermostat housing is for the EEC IV system)
The temp sending unit may be shorted to ground. Unplug the sending unit to see if the gauge drops to cold. If it does, you have a faulty temp sending unit.
A faulty temp sending unit can do that.
