Thermostats are used to regulate the coolant flow into the engine. As a matter of fact, to cool down an already cold engine would be a waste in terms of fuel, efficency and useless pollution.
The thermostat maintains the cooling circuit of the engine open (therefore, inactive), until it reaches the desired temperature. When the engine reaches the optimal working temperature, the thermostat kicks in and activates the coolant’s flow, maintaining an optimal temperature.
A broken thermostat can block itself into the open position; in this case the coolant flows into the cooling circuit even when the engine has not reached the optimal temperature yet. In winter, or in extreme conditions, this can affect the engine performance.
On the other hand, if it blocks itself on the closed position, the coolant does not flow in the circuit even with high temperatures, with the risk of serious damage to the engine.
This is why it is fundamental to have a working thermostat.
