The engine coolant overflow tube, also commonly referred to as an overflow pipe, expansion tank hose, auxiliary reservoir hose, or vent tube, is a small hose that connects the engine radiator (or radiator cap) to the coolant overflow reservoir/expansion tank.
Faults in overflow pipes are typically progressive and require regular inspection:
- Aging and Cracking: The most common fault, particularly at the two end fittings, due to long-term concentration of thermal stress.
- Hardening or Softening: Loss of elasticity, which may lead to loosening at connections or blockages.
- Internal Blockage: Caused by deteriorated flaking materials or deposits from using non-conforming coolant, resulting in restricted flow through the passage.
- Leakage at Connections: Loose clamps or aged/deformed pipe ends.
