- Helps maintain proper system pressure balance, preventing over-pressurisation.
- Supports stable coolant circulation by reducing air pockets within the cooling loop.
- Cracks or loose connections can cause coolant seepage around the reservoir area.
- A leaking breather line can lead to gradual coolant loss, requiring frequent top-ups.
- If the hose cannot vent properly, the system may experience excess pressure or improper pressure regulation.
- Low coolant or temperature warnings may appear if coolant loss occurs.
- A coolant odor in the engine bay is a common sign of leakage from the vent line.
- Common signs include cracking or splitting, hardened or brittle rubber, swollen sections, degraded connectors or fittings, coolant residue buildup.
