Compatible With LEXUS For ES300h 2.5L L4 For Hybrid 2013–2018 Engine Coolant Thermostat Housing Cover Assembly 1603136010 Function: The automotive coolant thermostat is a temperature-adjustable, constant-temperature heating device that controls the opening temperature, full-open temperature, and main valve lift. If any of these values do not meet the specified values, the thermostat should be replaced. Regular checks can improve vehicle performance. Material: This automotive coolant thermostat is made of ABS material, which is heat-resistant, impact-resistant, and highly reliable, making it trustworthy. 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%.
