What Is This Part?
This breather line forms part of the coolant expansion tank ventilation arrangement. It provides a passage through which air in the cooling circuit can reach the expansion tank, working alongside the tank and associated coolant pipework. Its condition matters both for keeping that passage clear and for maintaining sealed connections within the cooling system. The right-hand drive qualification identifies the applicable installation and must be checked when selecting a replacement.


What Does This Part Do?

  • Provides a breather passage: Allows air to travel towards the coolant expansion tank through the intended ventilation route.
  • Connects the ventilation circuit: Joins the expansion tank arrangement to its associated cooling system pipework.
  • Contains coolant: An intact line with correctly seated connections helps keep coolant within the circuit.


Why Replace This Part?
Replace the line if inspection confirms cracking, abrasion, distortion or leakage that prevents it from functioning correctly. Damage can allow coolant to escape, while a blocked or deformed passage can interfere with the intended ventilation route. Damp connections, dried coolant deposits or repeated coolant loss should prompt inspection of the line together with the tank and neighbouring pipework.

During expansion tank repairs, check the line and its connection points before refitting. Renew it if damage prevents secure seating or a sound seal; removing the tank does not automatically mean the breather line needs replacement. Coolant smells or gurgling alone do not identify this line as the cause, so confirm the source before changing parts.


When to Replace This Part?

  • Confirmed leakage: Fresh dampness or dried coolant residue is traced to the line or its connections.
  • Visible damage: Cracks, splits, rubbing damage or distortion affect the line.
  • Damaged connections: A connection is broken or cannot seat securely.
  • Restricted passage: Inspection confirms a blockage or deformation affecting the breather route.
  • Damage during repair: Removal or refitting leaves the line unable to reconnect correctly.


Where Is This Part Fitted?
Location: At the coolant expansion tank breather connection and associated cooling system pipework on the specified right-hand drive Macan applications.
