🔍 Key Concepts

• Automotive-type thermostat operation in a liquid cooling system • What happens when a wax pellet or bellows-type element loses its charge (fails) • Effect of fail-open vs fail-closed position on engine coolant temperature

💭 Think About

• Think about what the thermostat does when the engine is cold versus when it is hot. In which condition is it normally open, and in which is it normally closed? • If the bellows (or sensing element) loses its charge and can no longer respond to temperature, will the mechanism tend to stay in its spring-loaded (mechanical) position or its temperature-actuated position? • If coolant is allowed to circulate freely through the heat exchanger/radiator all the time, what will that do to the engine operating temperature compared to normal?

✅ Before You Answer

• Identify whether an automotive thermostat is normally open or normally closed when the engine is cold • Decide whether a loss of charge in the bellows makes it move more (open) or stops it from moving (so it stays in its default spring position) • Predict the resulting change in coolant temperature if the thermostat ends up stuck in that default position
