Breather Line. Porsche 970.2 Panamera 3.0L 2013-16  ❭  97010631061

The Breather Line is a OE MATCH coolant vent hose designed to connect the coolant expansion tank to the engine cooling system. This breather/vent line allows the cooling system to manage air and pressure changes while routing overflow coolant back into the closed-loop circuit. By supporting proper ventilation and fluid balance, it helps maintain stable engine operating temperatures and reliable cooling performance. It ensures precise fitment, durability, and resistance to heat and coolant exposure for Porsche Panamera (970) models.

Fits:

• Porsche 970.2 Panamera S V6 Turbo 3.0L 2WD (420Hp) 2014-16
• Porsche 970.2 Panamera S V6 Turbo 3.0L 2WD Executive 2014-16
• Porsche 970.2 Panamera 4S V6 Turbo 3.0L 4WD (420Hp) 2014-16
• Porsche 970.2 Panamera 4S V6 Turbo 3.0L 4WD Executive 2014-16  

• Vents trapped air and pressure from the cooling circuit into the expansion tank.
  
• Routes overflow coolant back to the coolant reservoir as temperatures rise.
  
• Helps maintain proper coolant level and pressure balance in the closed-loop cooling system.
  
• Supports stable coolant circulation, helping prevent air pockets that can reduce cooling efficiency.
  
  

• Prevents coolant leaks that lead to low coolant levels and reduced cooling performance.
  
• Maintains proper venting, allowing the cooling system to release trapped air and manage pressure changes.
  
• Helps avoid overheating, since coolant loss or air pockets can disrupt coolant circulation.
  
• Protects cooling system components, as pressure imbalance can stress hoses, seals, and the expansion tank.
  
• Restores reliable cooling system operation, ensuring overflow coolant is routed correctly back to the reservoir.
