It holds excess engine coolant as it expands when hot and returns it to the system as it cools, helping maintain proper cooling system pressure. The tank is constructed from high-durability, temperature-resistant plastic and comes with a 20 PSI pressure cap. Replacement is typically required when the original reservoir cracks, leaks, or the cap fails due to underhood heat and vibration over time.
