What happens if your thermostat is faulty?

A faulty thermostat most likely causes it to remain in its closed position. This means when the engine is running hot and the coolant normally flows toward it, the closed thermostat will block the coolant from going into the engine. This will cause the coolant to overflow from the thermostat housing.

What happens when thermostat goes bad?

A faulty thermostat will result in strange temperature changes during engine operation. In this case, the thermostat will not get stuck in one position, but there will still be false readings causing control issues. The engine temperature will change unpredictably and the radiator coolant will not flow normally.

How do I fix an unresponsive thermostat?
