Engine coolant overflow hose, commonly referred to in Chinese as the engine coolant overflow pipe or expansion tank connection hose, is a rubber or plastic hose connecting the radiator to the coolant expansion tank (overflow tank).

Its primary function is to transport excess coolant generated by thermal expansion and contraction, ensuring stable cooling system pressure and preventing coolant loss.

• Discharging during thermal expansion: When engine temperature rises and coolant expands beyond radiator capacity, the overflow hose directs excess coolant into the overflow tank, preventing excessive system pressure.
• Recirculating during thermal contraction: As the engine cools, a vacuum forms within the system. Coolant from the overflow tank flows back through the hose to the radiator, maintaining proper fluid levels.
• Preventing coolant loss: By creating a closed-loop system, it prevents coolant from leaking directly into the external environment.

The overflow pipe serves as the cooling system's “breathing” passage, ensuring dynamic fluid level equilibrium and preventing overheating or dry-running.
