THERMOSTATS

The Thermostat (or thermostatic valve) of a vehicle is an essential component of the cooling system. It regulates the flow of the engine coolant from the radiator to the engine and works specifically to maintain the temperature of the vehicle water in its optimum range.

When the car engine starts, the thermostatic valve is closed in order to allow the engine to reach the best working temperature. Once it reaches around 80-85° C, the thermostatic valve opens and the coolant flows.

If the engine temperature exceeds the standard limits, the cooling fan starts working in order to reduce the temperature again to its optimal level. On the contrary, if the engine temperature lowers below the inferior limit, the thermostatic valve closes interrupting the flow of more coolant in the system.

The way the thermostat works is quite simple but extremely important for the life of the engine. If the valve did not open, the coolant would not flow in the system, and this would cause a dangerous overheating of the engine, leading either to some break or the melting of some components such as the head gasket. If the valve got stuck in the open position, this would lead to a constant flow of water into the system, causing the engine to hardly reach the optimal working temperature, and inevitably leading to a higher waste of fuel.

Our suggestion is to keep the water temperature level on the dashboard under control: it must constantly be within the recommended range. In case of any problem, or if you have any doubts, contact your trustworthy mechanic for a further check.
