TOYOTA Thermostat 90916WX003

This is a genuine TOYOTA thermostat, part number 90916WX003, also identified by the new part number 90916-WX009. It is engineered to precisely control the engine's operating temperature by regulating the flow of coolant. A properly functioning thermostat is crucial for maintaining the engine within its ideal temperature range, which directly impacts fuel efficiency, emissions, and overall engine longevity. When the engine is cold, the thermostat remains closed, allowing the coolant to circulate only within the engine block, helping it reach its optimal operating temperature faster. Once the coolant reaches a predetermined temperature, the thermostat opens, allowing coolant to flow to the radiator for cooling. This continuous cycle ensures that the engine does not overheat during demanding driving conditions or prolonged idling. Replacing your thermostat with a genuine TOYOTA part guarantees compatibility and adherence to the manufacturer's strict quality standards. This ensures reliable performance and helps prevent potential engine damage caused by temperature fluctuations. Trust in genuine TOYOTA parts for the best fit and function for your vehicle.
