Follow the radiator hose from where it attaches to the radiator, the bulb it is attached to contains the thermostat. put the old one in a pan of boiling water to see if it opens and closes if not replace, be sure to clean the surface that this metal bulb rests one both bottom and top and use a good sealer when re installing with a NEW gasket, take care in NOT tightening the two bolts too tight as that is light cast iron or aluminum
