My car is overheating and stalling, and I want to check if the thermos-stat is sticking. Or else do any of you know what else it can be? There was a spray on my windshield, but checking I could not find any where that there was a leak.

u cant check a termo without taking it out so better to just change it, as far as the over heating that could b the thermo it could other things, water pump, it could b something in the system slowing or stopping flow or radiator, i would start with the thermo and water pump check hoses for leaks and flush the system

If it has overheated to the point that it quit running you should seek professional assistance. The engine has most likely been damaged internally. The cooling fan is electrical and depends on sensors and the engine computer to turn it on. The spray on the windshield can come from several different places, regardless, it sounds as if it's been too hot and may have sustained permanent damage. Red warning lights on the dash mean STOP the engine! Amber warning lights mean get to a service facility soon as possible. The thermostat may have failed but it sounds like there are more problems. The thermostat can't work if the system has a leak that allows the coolant to get low. Low coolant level in the engine block can go undetected if the system has leaks. A leak in the system will not allow the coolant to be drawn back into the engine block from the surge tank when the coolant cools down and contracts. The engine block gets low and the surge tank stays full. An air pocket forms behind the thermostat. The system needs pressure to raise the boiling point to about 240 degrees. If the system cannot pressurize the coolant boils at 212 degrees. The engine fan is programmed to come on at about 235 degrees. Do you see the snowball effect here? The coolant boils before the fan comes on, the thermostat does not open because the coolant turns to steam before reaching it and blows back through the radiator. That system has to be free of leaks and must have the air purged from the block while filling it. It must be able to pressurize to allow the system to function. Good luck
The thermostat should be at the engine end of the upper radiator hose. under the housing that the hose attaches to.

NEVER replace any part till you know the problem. DO NOT remove the thermostat. I guarantee it's not your problem. Make sure the radiator is full when cold. don't try to remove the cap when hot.Find a RADIATOR SHOP, not an auto repair, and get your car there. Don't continue running it hot you will do damage. You can't fix it yourself so don't experiment.

Is your coolant level low or normal? If normal then you probably do not have a leak.
To inspect the thermostat you have to remove it. If you are going to bother doing that then just replace the thing - they only cost a few bucks and even if it hasn't failed yet, it probably will later. Just get er done.
