If the thermostat is stuck open, the engine will be slow to warm and may not reach normal operating temperature. As a result, performance of the heater will be poor. Fuel economy will probably deteriorate. And the vehicle may fail emissions testing (if this is required where you live). Furthermore, engine wear may be accelerated in the long term. For all of these reasons, if a thermostat is stuck open, it should be replaced as soon as possible.
Thermostat may not be opening to allow coolant to flow through heater box. Thermostat may be opening too soon allowing cold coolant to flow through heater box. Either way thermostat needs replacing

The best indication of a bad thermostat is when the radiator fluid (Antifreeze) boils over from the reserve tank, not the radiator. This is caused by the thermostat not opening at its preset temperature and all the extra antifreeze is pumped directly to the reserve tank. You will also have loss of power and the vehicle will likely stop running soon after the antifreeze boils over.
