This is a genuine TOYOTA Pipe Sub Assy, Water By-Pass, part number 162090E040. Designed and manufactured to meet TOYOTA's stringent quality standards, this component plays a crucial role in your vehicle's cooling system. Proper functioning of the by-pass pipe is essential for regulating engine temperature, especially during warm-up phases. It allows coolant to circulate without going through the radiator when the engine is cold, helping it reach optimal operating temperature faster and reducing wear. When the engine heats up, the thermostat opens, and this pipe ensures the coolant continues to flow correctly through the system. Replacing a damaged or leaking by-pass pipe with a genuine TOYOTA part ensures a perfect fit and restores the integrity of your cooling system. This helps prevent overheating, leaks, and potential engine damage, maintaining the performance and longevity of your TOYOTA vehicle.
