The Porsche Breather Line for Water Tank is a genuine Porsche cooling system component designed to vent excess air and pressure from the coolant expansion tank while maintaining the correct operating conditions within the cooling system. Manufactured to Porsche's exact specifications for fit, flexibility and durability, this breather line helps ensure efficient coolant circulation and stable cooling system performance.
Fits:
- Porsche 95B.1 Macan S Petrol 3.0L V6 (340Bhp) 2014-18
- Porsche 95B.1 Macan GTS Petrol 3.0L V6 (360Bhp) 2014-18
- Porsche 95B.1 Macan Turbo 3.6L V6 (400Bhp) 2014-18
Diagram Ref No 22
Constructed from high-quality, heat-resistant reinforced hose, the breather line is engineered to withstand continuous exposure to coolant vapour, engine heat, pressure fluctuations and vibration. Precision-moulded for factory-correct routing, it provides secure, leak-free connections and supports the proper operation of the coolant expansion tank and engine cooling system.
What This Product Does:
- Vents air and coolant vapour from the coolant expansion tank.
- Helps regulate pressure within the cooling system.
- Maintains efficient coolant circulation.
- Supports proper filling and bleeding of the cooling system.
- Prevents air locks within the cooling circuit.
- Provides a secure, leak-free connection.
- Helps maintain stable engine operating temperatures.
- Forms an essential part of the engine cooling system.
Symptoms Of Wear Or Failure:
- Coolant leaks around the expansion tank.
- Visible cracks or splits in the hose.
- Coolant smell from the engine bay.
- Air entering the cooling system.
- Frequent coolant loss.
- Engine overheating.
- Coolant warning light or repeated low coolant warnings.
- White or coloured coolant residue around hose connections.
- Swollen, brittle or hardened hose material.
- Difficulty bleeding the cooling system after servicing.
Why Replacement Matters:
- The breather line is continually exposed to heat, coolant vapour, pressure changes and engine vibration. Over time, the hose material can harden, crack or lose flexibility, while connections may weaken, leading to coolant leaks or allowing air to enter the cooling system.
- A leaking or blocked breather line can disrupt pressure regulation within the coolant expansion tank, increasing the risk of air locks, coolant loss and engine overheating. Continued operation with a compromised cooling system can lead to reduced engine efficiency and potentially serious engine damage.
- Replacing a worn or damaged breather line restores the integrity of the cooling system and ensures the coolant expansion tank operates as designed. A genuine Porsche replacement provides factory-correct fitment, premium-quality materials and long-lasting reliability, helping maintain optimum engine temperatures, cooling efficiency and the dependable performance expected from your Porsche.
