A thermostat is a critical component in the engine cooling system, regulating coolant flow to maintain optimal engine temperature (typically 80-100°C). It remains closed during cold starts to accelerate warm-up and opens once the engine reaches operating temperature, allowing coolant circulation for heat dissipation.
