3. The thermostat is located inside the thermostat housing. To access the thermostat, you may need to remove the thermostat housing cover.
4. Once you have removed the thermostat housing cover, you will be able to see the thermostat. The thermostat is a small, round or hexagonal-shaped component with a spring-loaded valve.
