Vent Hose. Porsche 970.2 Panamera 3.0L 2013-16  ❭  97010642260

Vent Hose.
The Vent Hose is a genuine Porsche OEM coolant vent/overflow hose designed to route coolant vapours and excess pressure within the engine cooling system. This connector hose helps maintain correct cooling system balance by directing overflow coolant back to the reservoir, supporting stable coolant circulation and consistent engine temperature control. Manufactured to Porsche specifications, it provides precise fitment, durability, and long-term 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

What This Product Does:

• Routes coolant vapours and excess coolant back toward the coolant expansion/reservoir tank.
• Helps maintain proper cooling system pressure balance during engine heating and cooling cycles.
  
• Supports stable coolant circulation, helping prevent air pockets and pressure build-up.
  
• Keeps the cooling system operating as a sealed, controlled loop to protect against coolant loss.

Symptoms Of Wear Or Failure:

• Coolant may seep from cracks or loose connections, leaving dried residue or wet staining around the hose.
• A leaking vent hose can cause gradual coolant loss, requiring frequent top-ups.
• Improper venting may cause unstable system pressure, contributing to overheating or erratic temperature readings.
• A noticeable coolant smell in the engine bay often indicates leakage from the vent/overflow line.
• Common signs include cracking or splitting, brittle or hardened rubber, loose or damaged fittings, discoloration from coolant exposure.
  
• Low coolant or temperature-related warnings may appear if the hose begins to fail.

Why Replacement Matters:

• Prevents coolant leaks that can lead to low coolant levels and reduced cooling efficiency.
  
• Maintains correct pressure balance within the cooling system during temperature changes.
  
• Helps prevent overheating, since coolant loss or trapped air can disrupt proper circulation.
  
• Protects surrounding components, as leaking coolant can damage hoses, sensors, wiring, and nearby engine parts.
  
• Restores reliable cooling system operation, ensuring overflow coolant is routed correctly back to the reservoir.
