How do you know if your car thermostat is working?

Asked By: FacePalm Date created: May 01, 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: oz123 Date created: May 05, 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.
