No the thermostat is not in the radiator u havr to follow the upper rad hose to the motor on the top and u will find the housing it sits in usually held in by 2 or 3 bolts and u will need a new gasket and make sure u clean both surfaces before u put it back together make the bolts tight but not too tight and run car with rad cap open and add antifreeze as it needs it hope that helps
