Put thermostat in cold water on stove top. Turn on burner and when water begins to boil you should see it open if it is functional. Then prepare to be yelled at by your wife for doing it.

How do you check for a bad thermostat?
U take the thermostat out, get a pot of water, put the thermostat in it and start it to boiling. When the water reaches the temp that the thermostat is designed to operate at it should open , if not , it is defective
How do you get air out a car that is slightly running hot in a Honda Accord?
roll down the windows and turn the heater on full blast. It pulls hot air from the engine bay. Also check to see if you have a coolant leak or if your thermostat isn't opening all the way. you can test your thermostat in a pot of boiling water, boil the water to what ever degree thermostat you have. You could also burp the cooling system.
1995 Geo Tracker change the theromstat and heater core no heat in the car when running water ain't flowing though the raditior with thermostat in it. but take it out the water flows so What is wrong?
sounds like you installed new thermostat upside down if that's not the problem, you have wrong or faulty new thermostat to test thermostat out of vehicle, place in pot of boiling water and watch to see if thermostat opens
How can a thermostat be checked?
If you have it removed you can put it in a pot of boiliing water and see if it opens.
How do you know if your cars thermostat is partially stuck open?
Remove the thermostat from vehicle. Heat up a pot of water on the stove, insert thermometer in the water along with the thermostat, be sure to fill pot of water to cover thermostat. When temp reaches operating level (180 / 195 ) should be able to visually see thermost open. Get tongs and pull thermostat out of water. When it cools down you should see it close.
How do you check a 89 Chevy s-10 thermostat?
When in doubt, throw it out. If there is any doubt the thermostat may be bad, just replace it with a new one. If you insist on testing it, you can drop it into a small pot of water and heat it up on the stove. A 195 degree thermostat should open just before the water boils.
Why would antifreeze leak and started to smoke after a couple of miles driven it in the 1994 Chevy Silver ado?
If the smoke if coming from under the hood, then it sounds like your thermostat is stuck closed. Check the heat gauge (if equipped) on your instrument panel. If it is overheating or you don't have one, the next thing to do is pull the thermostat, take it to your kitchen, rinse it off, get a pot of water, place thermostat in pot (if using a nonstick pot, you will need to hold thermostat with tongs or something so you don't scratch the pot), and turn on your stove to high. The thermostat should open at around 195~200 degrees. I the thermostat doesn't open up right before the water comes to a full boil, then you have a bad thermostat and need to replace it.I am not sure where your thermostat is located. That is just a general troubleshooting procedure. you may have to drain your radiator before you can get your thermostat out. Keep in mind that antifreeze is poisonous to animals and humans if ingested and it does have a sweet taste so it is inviting to animals and it is a horrible death for them... If you have to drain it, dispose of it properly and refill with a 50/50 combo of antifreeze and water (distilled water recommended).
How do you tell if a new thermostat is defective?
Put the thermostat in a pot of water on the stove and boil it. Using a thermometer, check the temp. at which the thermostat opens and closes (most vehicles 185 - 215 degrees Fahrenheit). If no thermometer is available, then just the fact that the thermostat opens and closes around boiling tells you it's working (just not the specific operating temp. which matters in some vehicles and environments).
Replaced thermostat and radiator on 96 Camry 4-cylinder but now car is overheating and no heat when the car is overheating fans all work and now coolant is leaking from a tube What do you think?
Your description sounds like the thermostat is faulty. If the thermostat is stuck closed, there will be no heat for the interior. New thermostat's are occasionally bad, it has happened to me. The coolant is leaking from what tube? You can verify the thermostat operation, but unfortunately you must remove it from the engine (but with your symptoms that is the most logical failure). Put it into room temperature water in a pot on the stove. Heat the water and check the temperature at which it opens. This is a near foolproof check, but some thermostats are hard to tell when they open. You might have to pull it out of the water (use care it will be hot) to observe the open condition. In general 180-190 degrees F will be the temperature (water boils at sea level at 212 F) at which the thing is nearly fully open. But that depends on your exact version. The temperature is stamped on some them. For further advice read through the previous posts on overheating or thermostat replacement. Your description sounds like the thermostat is faulty.

1989 subaru legacy gets hot but the radiator does not What is wrong?
It sounds like your water pump is not circulating the water or the thermostat is stuck closed. The water pump and thermostat are at the front bottom of the engine attached to the bottom radiator hose. You may have a blockage, but that is less likely. To test the thermostat after you have removed it, drop it in a pot of boiling water and see if it opens.
Test a cars thermostat?
How to test a thermostat Most thermostats are rated to open at 190 degrees Fahrenheit. Testing the operation of a thermostat is simple: Get a pot of water heating on a stove, suspend the thermostat in the water by tying it to something that can hang across the top of the pot with some ordinary string, use a thermometer (one that can at least stand the boiling point of water which is 212 degrees Fahrenheit). Put the thermometer in the water along with the setup and watch the temperature. At around 190 degrees, the thermostat should open up indicating that it operates normally. If not, then it is defective, or it is rated to open at a different temperature. There is usually a stamp or engravement at the butt of the thermostat that shows its temperature rating.
What do you check when the temperature gauge on a 1996 explorer reads hot?
Sounds like the thermostat has stuck shut (gone bad). It's located where the to radiator hose attaches to the engine. To remove it loosen the hose clamp from the water neck then slide it off. once you've done that remove the water neck which is usually held on with two bolts. once you remove that the thermostat is right there. Just pry it off with a screwdriver. Do everything in reverse to replace it. Hint: To check to see if the thermostat is bad you can put in a pot of water and bring it to a slow boil. If it doesn't open when the water is boiling that means it's bad.
