If the thermostat does not close properly, then the coolant will not get up to "normal operating temperature" usually around 190 degrees Fahrenheit, and the heater will not work properly. Heated air will only be about 140 to 150 degrees (cool) and fuel mileage will suffer also. The vehicle is designed to operate within a certain engine temperature range.

If a thermostat in a vehicle's engine stuck open what will happen to the engine?
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.
