【High Quality】Constructed from high quality materials for optimum corrosion resistance and longevity, manufactured with precision to meet OE standards.
【Regularly Inspect】The engine coolant thermostat works by opening and closing at a predetermined temperature. When the engine is cold, the thermostat is closed, blocking the flow of coolant to the radiator and allowing the engine to warm up quickly. Once the engine reaches the desired operating temperature, the thermostat opens, allowing coolant to flow through the radiator and cool the engine.
