follow the upper radiator hose and you will see it going to a housing, unbolt the 2 bolts and its under there, when you picking up a thermostat get a haynes manual, they show how to do the basic maintenance

Yes you can follow the large top radiator hose out of the radiator, the housing should be located on the engine heads right at the front above your belt.
