[Reference Number] Manufacturer Part Number: 1122000015 A1122030275 A1122000015 1122030275 TI 45 87D TH31887G1 820495 78442 HOF8192599 FE102338 352317100680 Material: This coolant thermostat is made of metal, which is scratch-resistant, wear-resistant, sturdy, practical, and has high hardness, making it less prone to deformation or cracking, thus ensuring reliable durability and a long service life. Function: The function of an automotive coolant thermostat is to prevent insufficient engine cooling. The thermostat is a valve that controls the flow direction of coolant, ensuring its reliable heat and wear resistance. It effectively regulates heat dissipation, ensuring the engine operates within a suitable 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%.
