Not sure what year you have but on my 1984 its on top of the engine. Under the dome at the end of the radiator hose. There are 2 bolts that have to be removed in order to get to the thermostat. On a 1998 model, follow the top radiator hose to the engine. The hose attaches to an aluminum elbow with a brass slotted screw on top (the slotted screw is loosened to let air out of the cooling system). Remove the two bolts to take off the aluminum elbow and there will be your thermostat.
