Although I'm not familiar with a 2002, you should find the thermostat by following the upper radiator hose to the engine. Usually the easiest route from the left side to the block.
Not 100% sure, but if you have a 2.2L, that's how mine was. They haven't changed much.
To replace the thermostat on a 2002 Cavalier 22 Ecotec, drain the radiator and remove the upper hose assembly. Replace the thermostat and refill the radiator.

Look where the upper radiator hose connects to the engine. You will find the thermostat housing near that location. The thermostat may be inside the housing where the hose connects.
