What is a thermostat in a car?
A car thermostat is a small device that sits between the radiator and the engine of a liquid-cooled car. Its principal function is to regulate the flow of engine coolant from the engine to the radiator. When closed, engine coolant cannot flow into the radiator which can lead to a rapid increase in engine temperature.
What happens if the thermostat is closed on a car?
If the thermostat stays closed, the engine’s coolant cannot reach the radiator and, therefore, cannot cool down. This will cause the engine to overheat – which you can see in your dashboard with an ascending temperature display in the ticker – and you won’t be able to drive for more than 10 minutes before it starts overheating again.
When should I check the thermostat on my car?
If both your temperature gauge and the heat inside the car fluctuate, it is definitely a good time to check the thermostat. If the thermostat is not working properly, the hot coolant in the engine coolant chamber will find a way to escape because of too high pressure.
What temperature does a 195 degree thermostat open?
If a thermostat is advertised as "195 degrees," that means the thermostat is designed to start opening (thus allowing coolant to flow through the radiator and cool the engine) when engine coolant temperature reaches 195 degrees.
How do I know if my car thermostat is open?
Start your car's engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
How long should it take for thermostat to open?
Start your engine and let it idle for 10-20 minutes. From a cold start, your vehicle's thermostat will stay closed and you won't notice any coolant flowing into your radiator. Leave the vehicle running for about 10-20 minutes so it can reach its optimal running temperature.
Does a thermostat open and close?
The engine thermostat can open and close. When it's open, the coolant flows through, lowering the temperature of the engine. When it's closed, the coolant is blocked until the engine warms up.

What Does the Thermostat in a Car Do?
The thermostat is a valve that is strategically positioned in your cooling system, and it keeps tabs on your car’s temperature and releases coolant accordingly when it gets to be too warm. As long as your thermostat is doing its job and you have enough coolant in your car, you shouldn’t ever have to worry about your engine overheating. Your car will continue to push coolant from your radiator to your engine and then back again to keep everything at the right temperature.
