This is a genuine HONDA Reserve Tank, part number 19101PDAE00. It is designed to fit specific HONDA models, ensuring a perfect fit and reliable performance. The reserve tank, also known as an overflow tank or expansion tank, plays a crucial role in your vehicle's cooling system. Its primary function is to store excess coolant that expands when the engine heats up. As the coolant cools down, it contracts, and the reserve tank allows this coolant to be drawn back into the radiator, maintaining the optimal coolant level. This prevents the cooling system from running dry and protects the engine from overheating. Maintaining a functional reserve tank is essential for the longevity of your engine. A cracked or leaking tank can lead to coolant loss, overheating, and potential engine damage. Replacing a faulty reserve tank with a genuine HONDA part ensures that your cooling system operates as designed by the manufacturer.
