What is the Chevrolet Cruze thermostat heater?

[AnthonyLee]

The thermostat heater in the Cruze is a heating device that automatically activates when the temperature falls below the set value, continuing to heat until the desired temperature is reached. The thermostat is a valve that controls the flow path of the coolant. It is an automatic temperature-regulating device, typically containing a temperature-sensing component that uses thermal expansion or contraction to open or close the flow of air, gas, or liquid. Symptoms of a faulty thermostat in the Cruze include: 1. Thermostat malfunction with insufficient opening, affecting the engine's large and small circulation cycles, preventing effective heat dissipation, leading to elevated engine temperature and triggering the coolant temperature warning light; 2. Excessive thermostat opening, causing the engine temperature to remain too low, slow temperature rise, increased fuel consumption, and abnormal engine noises; 3. Thermostat sticking, which can lead to carbon buildup, resulting in unstable engine idle and causing engine vibration.
