[Reference Number] Manufacturer Part Number: 5184570AH 5184570AG 5184570AI 5184570AJ 68136754AA CTM-CH-014 TH7358.95J 908-95K K05184570A Function: The automotive coolant thermostat is 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: This engine coolant thermostat is constructed from robust metal, offering reliable heat dissipation. These characteristics ensure reliable performance, extend component life, and thus improve the overall efficiency of the vehicle. 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%.
