• Cooling system repairs requiring seal replacement.

As with most sealing components, O-rings should always be replaced once removed.

Symptoms of a Failing Coolant Breather Line O-Ring

Signs of a worn or damaged seal include:

• Coolant leaks around the breather line.
• Pink, white or dried coolant residue.
• Low coolant warning messages.
• Frequent coolant top-ups.
• Sweet coolant smell from the engine bay.
• Reduced cooling system pressure.
• Small coolant drips after driving.

Replacing the O-ring at the first sign of leakage helps prevent overheating and further cooling system damage.

When Should the O-Ring Be Replaced?

Replacement is recommended whenever:

• The coolant breather pipe is removed.
• Cooling system components are replaced.
• A coolant leak is diagnosed.
• Carrying out thermostat or water pump repairs.
• Performing preventative cooling system maintenance.
• Rebuilding or servicing the engine.

Installing a new O-ring during reassembly ensures a reliable seal and reduces the risk of future coolant leaks.
