This is a genuine TOYOTA Radiator Reservoir Tank Assembly, part number 16470F0011, specifically designed for US market vehicles. This essential component plays a critical role in your vehicle's cooling system. It serves as a storage container for excess coolant that expands when the engine heats up, preventing it from being lost. As the engine cools, the coolant is drawn back into the radiator, maintaining the optimal coolant level. Proper functioning of the reservoir tank is crucial for preventing engine overheating and maintaining the integrity of the cooling system. A damaged or leaking tank can lead to coolant loss, air entering the system, and ultimately, costly engine damage. Ensure your TOYOTA is equipped with a reliable and properly functioning cooling system by using this OEM replacement part. It is manufactured to meet TOYOTA's stringent quality and performance standards.
