You follow the top radiator hose from the radiator to the engine. The housing that the hose connects to has the thermostat inside. Unclamp the hose, wrestle it off the housing, unbolt the housing and pull out the thermostat. The housing will also have a gasket or "O" ring that should also be replaced at the same time......... Oh yeah, did the mention you should also have a drain pan to put under the radiator and undo the pet cock to drain as much coolant as possible before you start...
