well an exact answer would rely on the motor size, but in most cases you just follow the top radiator hose from the radiator to the place it connects to on the motor.. where it connects there will be a small metal housing with 2 or maybe 3 bolts.. remove the bolts and you should be able to find the thermostat hiding under it lol...
