Breather line
The Porsche Genuine OE Breather Line (Part No. 97010631001) is an original factory engine coolant vent / breather hose designed for the Porsche 970 Panamera models up to 2013.

Fits:
Porsche 970.1 Panamera 3.6L >>2013
Porsche 970.1 Panamera 4.8L S / GTS / Turbo >>2013

Diagram ref no 11

The breather line allows trapped air and coolant vapour to circulate correctly within the cooling system, helping maintain stable coolant pressure and efficient coolant flow. Proper venting is essential for preventing:
• Air pockets within the cooling system
• Pressure build-up
• Coolant overflow or circulation issues
This helps ensure efficient engine temperature control and reliable cooling system operation.

Functions & Technical Role
•  Cooling system venting: Helps remove trapped air from the coolant system
•  Pressure regulation: Assists in maintaining stable coolant pressure
•  Coolant circulation support: Helps optimise cooling system efficiency
•  Leak prevention: OE hose construction designed for secure sealing and durability
•  OEM precision: Manufactured to Porsche factory specifications for exact fitment and reliability

Fitment / Position on car
•  Fitting position: Engine cooling system
•  Location: Engine coolant line / engine block vent circuit
•  System: Cooling and venting system

The breather line helps maintain efficient coolant circulation and prevents trapped air within the cooling system. A damaged or leaking hose can affect coolant pressure and overall engine cooling performance.

When to replace
•   Coolant leaks around the hose connections
•   Cracked, brittle, or swollen hose material
•   Cooling system pressure issues
•   During coolant system overhaul or engine service
•   Signs of coolant vapour or air ingress in the system

Breather line
This OE match breather line is a direct replacement for the original Porsche coolant vent hose fitted to Porsche 970.1 Panamera models equipped with 3.6L and 4.8L petrol engines. It forms part of the engine cooling system and helps regulate coolant circulation, pressure equalisation, and venting within the cooling circuit.

Fits:
Porsche 970.1 Panamera 3.6L >>2013
Porsche 970.1 Panamera 4.8L S / GTS / Turbo >>2013

Diagram ref no 11

The breather line vents and circulates coolant within the engine cooling system, helping maintain correct coolant pressure, eliminate trapped air, and support stable engine operating temperatures.

Function
•  Connects coolant vent and expansion tank pipework
•  Helps eliminate trapped air from the cooling system
•  Supports coolant circulation and pressure regulation
•  Maintains stable engine operating temperatures
•  Reduces risk of coolant leaks and overheating

Cooling system vent hoses are constantly exposed to heat, coolant pressure, and vibration. Over time, the hose material can harden or crack, increasing the risk of coolant leaks and cooling system pressure loss. Replacing worn breather lines helps maintain reliable cooling system operation and reduces the risk of overheating or engine damage.

When to replace
•  Visible coolant leaks or staining
•  Cracked or brittle hose material
•  Cooling system pressure loss
•  Overheating or fluctuating coolant temperatures
•  During preventative cooling system maintenance
•  During radiator or expansion tank replacement

Diagram Ref No 7 (Diagram Ref No 8 and 9 Included)

What This Product Does:

• Feeds engine coolant between cooling system components such as the engine, radiator, and expansion/overflow tank.
• Helps maintain proper coolant circulation, which is essential for controlling engine temperature.
  
• Supports overheating prevention by ensuring coolant flows efficiently through the system.
  
• Provides a flexible connection that absorbs engine movement and thermal expansion without stressing rigid pipes.
  
  

Symptoms Of Wear Or Failure:

• Coolant may seep or drip from the hose itself or around the hose clamp connection points.
• A worn feed hose can cause gradual coolant loss, leading to repeated topping up.
• If the hose leaks or restricts coolant flow, the engine may run hotter than normal.
• A coolant leak often produces a sweet smell in the engine bay or around the vehicle.
• Visible signs of deterioration may include cracking, bulging, hardened rubber, wet staining
  
• If coolant circulation is affected, cabin heat may become weak or inconsistent.
• Modern Porsche models may display coolant level or overheating warnings when leaks develop.

Why Replacement Matters:

• Prevents coolant leaks that can cause low coolant levels and loss of pressure.
  
• Helps avoid engine overheating, which can lead to severe and expensive engine damage.
  
• Restores proper coolant circulation, ensuring the cooling system performs efficiently under all conditions.
  
• Maintains reliable heater performance, since cabin heating depends on correct coolant flow.
  
• Protects other cooling components, as leaks can introduce air into the system and increase strain on hoses, seals, and the water pump.
