Take off the radiator cap of the car. Start it up and watch the temp guage. when the car starts getting warm look in the radiator and see if you have water flowing. If not that is a sign it's bad.

How do you determine if your thermostat is bad?
When the car is hot, squeeze the upper radiator hose. If it feels soft, then the thermostat is not opening and therefore bad. If you squeeze the hose and its hard to squeeze, then it is pressurized and the thermostat is open. That is one way to check if the thermostat is stuck closed. If the thermostat is stuck open, then in cold conditions the car will take a long time to produce hot air from the heater.
