It is in a housing in the engine end of the upper rad hose. Just take it out and when you go back with it make sure the spring goes toward the engine.
**Additional: The thermostat comes with a rubber ring to seat and seal the part into the counterbored holder. The paper gasket included with the thermostat should also be used as a spacer to maintain proper alignment of the pipe flange that is bolted over the thermostat. If the paper gasket is not used, the pipe flange will be bent into a slight arc because the rubber gasket is quite thick. Don't let the parts guy tell you that you don't need the gasket because of the O-ring. It's because of that O-ring that you do need the paper gasket.
