[Reference Number] Manufacturer Part Number: A2782000815 2782000815 A2782000415 2782000415 Product Features: This coolant thermostat provides precise temperature control, designed to accurately regulate engine coolant flow, helping the engine reach and maintain a reliable operating temperature faster, especially during cold starts or prolonged idling. Material: We proudly present our automotive coolant thermostat made of ABS material, reliable, and effective at controlling engine operating temperature to prevent overheating. 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%.
