TOYOTA Radiator Reservoir Tank Assembly - Part 1647037021

This is a genuine TOYOTA radiator reservoir tank assembly, specifically designed for JP model vehicles. It plays a crucial role in your vehicle's cooling system by safely storing excess coolant that expands when the engine heats up. As the engine temperature rises, the coolant expands and is pushed into the reservoir tank. When the engine cools down, the coolant is drawn back into the radiator. This assembly helps maintain the correct coolant level and prevents air from entering the system, which is vital for efficient cooling and preventing overheating. Crafted to meet TOYOTA's stringent quality standards, this part ensures a perfect fit and reliable performance. Replacing a damaged or leaking reservoir tank is essential for the longevity of your engine and the overall health of your cooling system.
