Follow the upper radiator hose from the radiator to the engine and at tne engine you will see the thermostat housing. Take out the two bolts and remove the thermostat and when you reinstall it make sure the spring goes toward the engine. You will likely need a deep socket set in order to remove the bolts. You may also need to remove the air filter in order to access the bolt to the rear.
Have a care when replacing the thermostat housing. The constant heating and cooling (and likely the chemicals in the anti-freeze) makes the metal brittle.
