Checking For the Signs of a Bad Thermostat 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.
What causes thermostat to stick?
The most obvious cause is a blocked radiator, low water level, or a failed cooling fan. There are more involved reasons that include failed/ failing water pump, internal obstruction in the radiator, or the engine itself.
Can a thermostat be stuck open?
Symptoms of a bad thermostat Thermostat stuck open: When the thermostat is stuck open, the engine temperature drops below normal when driving, especially on the highway in cold weather. A stuck-open thermostat can also cause lack of heat from the heating system. The Check Engine light may come on too.
Can a thermostat be stuck closed?
If the thermostat becomes stuck in the closed position, the circulation of the coolant is blocked so the coolant cannot get to the radiator to be cooled which causes the engine to overheat.
What happens when a car thermostat is stuck closed?
Your vehicle’s thermostat opens to allow coolant to flow through the radiator and cool the engine down. However, if the thermostat gets stuck in the closed position, the coolant can’t flow through the radiator and can make your engine overheat.
How long can I drive with a bad thermostat?
Yes, but not for very long. Thermostats typically “fail closed,” which means your coolant won’t circulate and you’ll overheat very quickly. I wouldn’t – even removing the thermostat is better than leaving a failed thermostat in place (it will take longer to warm up, but it won’t overheat on you!)
What would cause thermostat not to open?
Once the coolant engine reaches proper operating temperature, typically 180 to 200 degrees, the thermostat opens up and allows the coolant to flow through the engine. Sometimes the thermostat fails and must be replaced; there are four main reasons for failure: overheating, sludge, defect and age.
How do I know if my thermostat is stuck open or closed?
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.
How can you tell if your thermostat is stuck closed?
The coolant should warm to the right temperature and begin to flow after 10 to 20 minutes. If it does not start to flow, but the temperature gauge on your dashboard rises, your thermostat is stuck closed.

Can you drive a car with a stuck thermostat?
Yes, you can drive a car without a thermostat. The thermostat function is to force the engine to operate at a specified temperature. Combustion engines are more efficient when operated hot. Of course too much heat is detrimental to the engines life. Drive it as long as you desire without the thermostat.
How can you tell if your thermostat is sticking?
