Information
Breather Line.
The Breather Line is a genuine Porsche OEM coolant vent tube designed to manage air, vapour, and overflow flow within the engine cooling system. This breather line connects key cooling circuit components to help regulate pressure changes and maintain proper coolant circulation, supporting stable engine operating temperatures and efficient cooling performance. Manufactured to Porsche specifications, it provides precise fitment, secure sealing, and long-term resistance to heat and coolant exposure. Designed for Porsche models 971.1 / 971.2 / 9YA, this breather line is essential for maintaining cooling system reliability and preventing pressure-related coolant issues.

What This Product Does:
- Vents trapped air and coolant vapour from the cooling system.
- Helps regulate cooling system pressure as temperatures rise and fall.
- Routes overflow coolant between the expansion tank and the main cooling loop.
- Prevents air pockets that could reduce coolant circulation and cooling efficiency.
- Cracks or loose fittings may cause coolant seepage near the vent line or expansion tank area.
- A leaking breather line can gradually reduce coolant levels, requiring frequent top-ups.
- If the line cannot vent properly, excess pressure may build up in the cooling system.
- Low coolant or overheating warnings may appear if leakage or pressure issues develop.
- A noticeable coolant odor in the engine bay often indicates leakage from the vent line.
- Common signs include cracking or splitting, brittle or hardened material, damaged connectors, coolant residue buildup.
- Air entering the cooling system or improper venting can reduce cooling efficiency.
Why Replacement Matters:
- Prevents coolant leaks that can lead to low coolant levels and reduced cooling performance.
- Maintains correct venting, allowing air and vapour to escape and preventing pressure buildup.
- Helps avoid engine overheating, since trapped air or coolant loss can disrupt circulation.
- Prevents air pockets in the cooling system, improving heat transfer efficiency.
- Protects surrounding components, as coolant leaks can damage wiring, sensors, and nearby engine parts.
