As the engine heats up, the thermostat should open up and allow the coolant to flow from the radiator to the engine.

If you see the coolant flowing through the radiator, then the thermostat opened and is working properly.

If not, then it is most likely stuck closed..

Can a thermostat be partially stuck?

Asked By: qbik Date created: May 08, 2022

Thermostat valves can fail in one of three ways: open, closed or stuck halfway. If the valve sticks in the closed position, coolant will constantly recycle through the engine without going to the radiator, causing the engine to overheat.

How do you know if your car thermostat is working?

Asked By: Niyaz Date created: May 13, 2022

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.

What does a stuck closed thermostat look like?

Asked By: Ian Vink Date created: May 04, 2022

Look to see if the coolant is swirling/flowing immediately — that means the thermostat's stuck open. If the coolant doesn't flow after 10 minutes or so and continues to be stagnant after the temperature gauge indicates it's hot, the thermostat's likely stuck closed. Replace the radiator cap and turn off the engine.

A vehicle can run just fine if the thermostat doesn't open. It will run on the warm side, not past halfway, and heat the interior just fine. But, when the weather gets warmer outside that thermostat stuck closed will not be able to allow the reservoir water flow and the vehicle will begin to have overheating issues.

How does a thermostat go bad in a car?

Why Car Thermostats Fail. Car thermostats fail when the valve of the thermostat fails to open, fails to close or gets stuck in a partially-open position. As the thermostat controls the flow of coolant to the engine, this can keep the car from warming up or cause it to overheat.

Can a thermostat fail closed?

All thermostats will fail in either a closed or open position; there is no such thing as a thermostat that will fail in a “safe” position. Although some brands may claim a thermostat fails in a safe position, it simply locks itself open while it is in a full stroke open position.

Thermostats fail because they become weak, stuck open or stuck closed. When a thermostat is stuck open, coolant constantly circulates and the engine takes longer to reach operating temperature.
