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 If The Thermostat Is Stuck Closed? If the thermostat is stuck closed, it will not be able to get rid of the water as quickly as it needs too. As the water runs through the engine, it absorbs the heat of the engine. It is important that as things heat up, it can disperse the hot water and get fresh cooler water to the engine block.
How do I know if my thermostat is stuck closed?
Can you drive with thermostat stuck closed?
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.
What happens when thermostat is closed?
When the thermostat is closed (as it should be when first starting the engine), coolant is prevented from circulating. This quickly brings the engine to optimal operating temperature. Once this temperature is reached, the thermostat opens and allows coolant to pass through the radiator, hoses and engine to cool it off.

Will a stuck closed thermostat cause no heat?
A stuck-open thermostat can also cause lack of heat from the heating system. The Check Engine light may come on too. Thermostat stuck closed: When the thermostat is stuck closed, the engine might overheat. Besides these two cases, the thermostat may also need to be replaced if the thermostat housing is leaking coolant.
Can a stuck thermostat be fixed?
It's inexpensive and a fairly straightforward process. In short, you need to drain your coolant, disconnect the housing, remove the current thermostat, put in a new one, reconnect the housing, then refill your coolant line. In this guide, I'll tell you exactly how to unstick the thermostat in your car.
Can a stuck closed thermostat cause coolant loss?
4. Coolant Leaks Around Thermostat Housing or Under Vehicle. Another indication may be leaking coolant, which can occur when the thermostat does not allow coolant to flow when stuck in the closed position. This can be noticeable in a variety of locations, but most commonly around the thermostat housing.
How do you check if a thermostat is working?
Check the screen: Check the screen of the thermostat and make sure that it is lighted. A blank or unlighted screen could indicate a thermostat failure. Check the batteries: Many modern thermostats rely on battery power to operate. If the screen is blank or unlighted, a battery change could solve the problem.
How long does it take for a thermostat to open?
The thermostat can be opened within a few minutes depending on the temperature outside. It should open within five minutes.

Why is cold air coming out of my car vents when the heat is on?
Low Coolant Level The coolant (usually a mixture of water and antifreeze) in your engine doesn't just work to keep the engine from overheating: It's also the source of heat supporting the heating system. If there isn't enough coolant in your system, the heater core will blow cold air into your car.
How do I know if my radiator is flowing?
Why is my car running hot but not overheating?
If you find that you've got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.
What tells the thermostat to open?
At low temperatures, the outlet to the radiator is completely blocked -- all of the coolant is recirculated back through the engine. Once the temperature of the coolant rises to between 180 and 195 F (82 - 91 C), the thermostat starts to open, allowing fluid to flow through the radiator.

How can I tell if my water pump is working?
With the engine off, open your hood and locate the water pump pulley. With gloves on, grab it and wiggle it back and forth. There should be no movement, if there is, this along with the noise is a good indication you may have a water pump problem.
What causes coolant to not circulate?
The coolant level could be extremely low because of long-term neglect, or because a coolant leak has developed in the radiator or radiator hoses. Coolant circulates inside the engine block to cool it, and the leak might be in the block, or from the water pump or heater hoses.
How does a car act when the thermostat is bad?
If the car thermostat is bad, it won't allow coolant from flowing into the engine, which ultimately causes the car to overheat. So when this happens one of the possible causes is a broken thermostat.
What happens when the thermostat is stuck closed on a car?
The thermostat closes when the engine is cold, allowing coolant to remain in the engine block and warm it up. When the engine reaches operational temperature, the thermostat opens, allowing coolant to flow through the radiator and cool it. The engine will overheat because the coolant cannot flow when the thermostat is stuck closed.
What should I do if my thermostat is stuck?
Using your finger, carefully touch the top and bottom radiator hoses for a couple of seconds. If one is very hot and the other is cool, your car’s thermostat is likely stuck in the closed position. Alternatively, let your car idle for a while and open the hood with the engine still running.
Can a thermostat fail in the open position?
Some thermostats are designed to fail in the open position if a part of the device breaks. This is considered more desirable than feeling in the closed position because that would prevent coolant from circulating and your engine to overheat. It's easier to deal with the engine running too cold then it is to deal with one that runs too hot.
Can a thermostat that opens and closes when put in hot water?
Question: Can a thermostat that opens and close when put in hot water still become stuck at close when installed in the car? I am experiencing this situation. Answer: It is unlikely a problem with the thermostat if it has proven to open and close fine in boiling water.
