On the passenger side of the car, trace the hose from the bottom of the radiator upwards. This hose is tapped by another hose from the coolant surge tank. Follow the hose towards the engine block. The thermostat is located at the end of this hose. There are two small screws that hold the thermostat housing to the larger housing. Apply penetrating oil to these screws if they are tight. Remember to drain the radiator of coolant before removing the thermostat housing. There is no gasket between the thermostat housing and the larger housing. When remounting the housing, use the paste that is specifically manufactured for this purpose. It is sold at any auto supply store. Remember which direction the spring of the thermostat points before you remove it.
