Function: The engine coolant thermostat is designed to regulate the cooling capacity of the cooling system to ensure that the engine operates within the appropriate temperature range. Regulating Coolant Circulation: The coolant thermostat acts as the core temperature-control valve, automatically switching between small and large circulation loops based on coolant temperature. During a cold start, it closes the passage to the radiator, confining coolant circulation to the engine's internal "small loop" to help the engine rapidly reach its ideal operating range of 85–95°C. Maintaining Constant Operating Temperature:Once the target temperature is reached, the valve gradually opens to direct coolant into the radiator for "large loop" cooling. This prevents overheating and stabilizes the operating temperature within the optimal range, thereby boosting combustion efficiency by 12%–15%.
