Yes they can stick open or closed. An automobile thermostat is just as likely to stick open as it is to stick shut. Symptoms of a stuck open thermostat are slow to reach normal operating temperature and only warm air blowing from the heater. Symptoms of a stuck closed thermostat are engine over-heating and radiator boil-over.

How do you know if a thermostat is bad in a 1994 astro van?
Faulty thermostats can manifest themselvs in several ways. Some stick open, some stick closed and some stick in one position for a while then suddenly open or close. The ones that stick open will never allow the engine to completely warm up and you will get cold or cool air coming from the heater. The ones that stick closed will cause the engine to warm normally but then the temprature continues to climb and you can loose coolant and possibly harm the engine. The ones that stick for a while are interesting because the vehicle will run cold then turn warm quite rapidly or more likely the thermostat will stick closed and not open until the vehicle is quite warm and possibly you have started to loose coolant. In any case, the easiest way to detect a bad thermostat is to replace it. If the problem goes away, it was the thermostat. If you REALLY need to know if the thermostat is bad, remove it from the vehicle, put it in a pan of water and bring the water to a boil on the stove. Watch the thermostat. If it opens smoothly when the water gets to the designated temprature then the thermostat is ok. If the thermostat opens suddenly, fails to open or is open when you remove it from the vehicle, the thermostat has failed.
What affect will a bad thermostat have on an automobile heating system?
A stuck open thermostat will not allow the coolant to get up to proper temp, thus poor heat from heater. A stuck closed thermostat will not let coolant circulate and will cause the engine to overheat.

Can your thermostat be stick?
Yes
Can a bad thermostat cause your battery to go dead and ac blow hot air And what other negative effects can a bad thermostat have on your vehicle?
I've actually heard a bad thermostat can cause the evaporator core to malfunction.I've also heard of some a/c compressors will shut off if the engine temp gets to high which could be a thermostat issue. No, the thermostat has no effect on the battery or on the A/C. A thermostat either works correctly or it will stick open or stick closed. Sticking open will cause the engine to never reach full operating temperature, and as such your heater will not work properly. A thermostat stuck closed will cause the engine to overheat.
Why does the Temperature in my CRV Honda increases then drops to normal?
check the thermostat. they often stick and then when the temp goes up it will open and let coolant flow.
What effect will a bad thermostat have on an automobile heating system?
AnswerA bad thermostat won't give you any heat and or it will give you too much heat. You would be wise to change it. Usually there are two bolts that hold a thermostat in place. You need to remove these two bolts, take the old thermostat out and see how high the temperature setting on it is. Some cars have a temperature of 165 F while other cars go as high as 195 F. To be sure you are getting the right thermostat for your car you can always go to an Auto Parts store, give them the make and model for your car along with the year and they should be able to give you the right one for your car.Good luck.AnswerA thermostat can fail in one of several ways. It can stick open, which means that, in cold weather, the engine will not warm up properly, or the thermostat can stick closed, which will result in the engine overheating, or the device can stick somewhere between the two extremes, which usually will result in the vehicle running cold. The easiest way to check the thermostat is to remove the radiator cap with the engine cold, start the engine, and let it warm up. When the coolant reaches the preset temp of the thermostat, the thermostat should open, which will allow hot water to enter the radiator.

How do you know if your 95 geo prizm needs a thermostat change?
Thermostat can stick open or closed. If sticks open, car will take longer to warm up because coolant is constantly flowing thru engine. If thermostat is stuck closed, engine will eventually overheat. In order for all emission systems to work properly, thermostat needs to be working. For 1995 GEO Prizm, if thermostat is working correctly, car should maintain proper operating temperature after is warmed up. If any doubt about thermostat, changev it every few years as is inexpensive and easy to replace.
