Overheating if stuck closed, no engine heat if stuck open.
That is the most common symptom of thermostat stuck in open position.
Usually the car would run cool, unless the thermostat is stuck partially open.
A good symptom of a thermostat stuck open is that it takes the engine longer than normal to reach operating temperature. ============================================================ Just adding to the answer : It will also show that it is running much cooler on the engine coolant temperature gauge than it normally does with the engine warmed up
If the engine is overheating, the thermostat is stuck closed. If the heater is not putting out enough hot air the thermostat is stuck open. Change the thermostat as a normal part of maintenance when changing coolant.
IF the thermostat gets stuck open you will not have heat in the winter. The car will take a very long time to warm up in cold climates. If the thermostat gets stuck closed, the motor will quickly become too hot, as measured by the temperature gauge. This symptom can also be seen if the motor freezes in the winter. The engine heats up by the coolant in the radiator stays frozen, so water can not circulate. Hope this helps!
No heat coming from the heater and the car overheating is usually the thermostat stuck closed. The thermostat is supposed to open up at a certain temperature allowing the engine to warm up quickly.

A stuck closed thermostat can lead to severe overheating which can lead to severe engine damage which then leads to big money for repairs.

Replace it.
A thermostat can be stuck open or closed. If the engine runs to cool it is stuck open. If the engine is running hot it is stuck closed. If you don't have these problems you should'nt have to change it.
yes if the thermostat is stuck open the gauge will read low the water or antifreeze will flow straight through the engine and radiater if it is stuck closed it will over heat your car
