[Reference Number] Manufacturer Part Number: 1338027, 1338297, 18528-79J80, 18528-79J80-000, 18528-79J81, 18528-79J81-000, 55241963, 55566104, 55573003, 71752861 Product Features: This automotive coolant thermostat features enhanced temperature regulation: it automatically adjusts coolant flow to maintain a reliable engine temperature, Material: The automotive coolant thermostat housing and water pump outlet are made of reliable and robust ABS material, offering stability, strength, and extended service life. 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%.
