The easiest way to find it is to follow the upper radiator hose from the radiator to the engine. The place it enters the engine is probably the thermostat housing. From there, you probably have two bolts to take it off. Replace the stat and the gasket. Make sure you clean the mounting surfaces well. Good luck!!!!!
