Pull out the thermostat and try a new one. Also, it could be that the guage is just off. Try using a thermometer to get the engine temp. I'd suggest getting another Zetec to compare to.

For one, I dont' even know where the thermostat is at.

2, it was doing it before and the thermostat was replaced, and still never corrected the reading shown in the cluster.

So it was doing it, and still doing it after a new thermostat.

As I stated, the heat works fine, and the top hose gets warm. If you squeeze the hose you can feel fluid rushing through once you release it.

From doing the above, it lead me to believe that the thermostat wasn't at fault. It's opening and closing as it should.
