Thermostat, this valve is responsible for moderating the temperature of a vehicle’s engine. While many of us are aware of the potential perils of an engine overheating, an engine also will not work properly when it is too cold. Therefore, it is the job of the thermostat to regulate the temperature between these extremes, creating a happy medium that promotes optimum driving by controlling the flow of coolant that can circulate the engine. The thermostat valve allows coolant to circulate and keeps the engine cool.
As it functions as a valve, the thermostat has 2 positions: open and closed. When the valve is in the open position, coolant is able to flow through it, which lowers the engine’s temperature. When the valve closes, it blocks the entry of fresh coolant to the engine, allowing it to warm up. This part works alongside your vehicle’s radiator. When the coolant has become too warm, it passes it back to the radiator, which works to return it to a suitable temperature.
Cold Engine – When the thermostat determines an engine is too cold, it closes itself. This prevents coolant from leaving the engine and being cycled to the radiator for cooling. This allows the coolant to warm up with the engines heat, warming the engine overall.
Hot Engine – When the thermostat determines the engine is becoming too hot, it opens. This allows fresh, cold coolant to enter the system, which starts to cool it down to a safer temperature. The coolant which had become warm is cycled out to the radiator for cooling.
In short, without your vehicle’s thermostat, your engine is at risk of running too hot and overheating or running too cold and shutting down. The thermostat keeps the engine at its optimum temperature, meaning the parts of your engine system can work to the best of their ability and will last longer, all while giving you the best drive possible in the process.
