[Reference Number] Manufacturer Part Number: 11537536655 11537549476 11537544788 Function: The engine coolant thermostat is manufactured using reliable processes and undergoes strict quality control to ensure reliable heat and wear resistance. It effectively regulates heat dissipation, ensuring the engine operates within a suitable temperature range. Material: The thermostat is made of metal, offering heat resistance and impact resistance, keeping the engine at a reliable operating temperature, thereby improving overall engine performance and efficiency, extending its lifespan, and reducing replacement frequency. 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%.
