If the thermostat is plugged or stuck closed, the vehicle will usually run very hot or overheat quickly. But sometimes, if the thermostat is stuck open, the vehicle will not heat up to normal operating temp.(hard to tell in summer and not particularly harmful, unless using air conditioning, but very noticeable in winter when the heater won't heat and the engine runs constant high idle). A more visual way to check for certain is to remove the thermostat from the engine (usually a fairly simple procedure involving only partial draining of the radiator, a couple of bolts, a gasket, and some sealant). 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). However, as inexpensive (usually) as thermostats are, if one goes to the trouble of removing it from the car, one might as well buy a new one of the correct temp. range, install it in the vehicle and be done with it.
If your radiator isnt leaking and car is having a over heating problem and coolant spewing out. Chances are your thermostat needs replaced. possible the radiator needs to be flushed. But more likley its thermostat

Be sure the thermostat is not installed backwards.
If you suspect the thermostat is no good, replace it with a new one, don't leave it out.
1. If the engine is running hotter than usual. 2. If the vehicle's temperature gauge is showing the low. 3. If upon inspection you see an open thermostat valve Symptoms like these likely indicate you need a new thermostat
To change the thermostat in a car, first locate the thermostat housing. Drain the coolant, remove the housing, and take out the old thermostat. Install the new thermostat, replace the housing, and refill the coolant. Be sure to follow the manufacturer's instructions and use the correct tools for the job.
You will need a new head gasket if you see engine coolant in the oil. I don't know about the thermostat.
