[Reference Number] Manufacturer Part Number: 12622410 Function: Automotive coolant thermostats are crucial for regulating engine temperature, preventing overheating, improving fuel efficiency, reducing wear on engine components, ensuring proper heater , and providing vital coolant temperature information to the engine control unit. Material: Our engine coolant thermostats are made of metal, offering excellent wear resistance and reliability. They undergo rigorous quality control, meet standards, and maintain stability in various harsh operating environments. 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%.
