Vent Hose. Porsche 970 Panamera 3.6L / 4.8L 2010-16  ❭  97010642202

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 hose helps maintain proper cooling system balance by directing overflow coolant and vented pressure to the coolant reservoir, supporting stable engine temperatures and reliable cooling performance. Manufactured to Porsche specifications, it provides precise fitment, durability, and long-term resistance to heat and coolant exposure for Porsche Panamera (970) models.

• Vents excess pressure from the cooling system during temperature changes.
  
• Routes coolant vapours or overflow safely to the coolant expansion/reservoir tank.
  
• Helps maintain correct system pressure, which is essential for stable engine cooling.
  
• Prevents coolant from escaping into the engine bay, helping keep the cooling system sealed and efficient.

• Coolant may seep from cracks or connection points, leaving dried residue around the hose or nearby components.
• A leaking vent hose can cause gradual coolant loss, leading to frequent top-ups.
• If the vent hose cannot manage pressure correctly, the cooling system may not regulate pressure as designed.
• A noticeable coolant smell in the engine bay or near the rear of the vehicle often indicates a leak.
• Common signs include cracking or splitting, brittle or hardened rubber, loose or deformed hose ends, wet staining or discoloration.
  
• Low coolant or pressure-related issues may trigger warning messages on the dashboard.

• Prevents coolant leaks that can lead to low coolant levels and cooling system pressure loss.
  
• Maintains correct cooling system venting, allowing pressure to stabilise during heat expansion and cooling cycles.
  
• Helps avoid overheating, since coolant loss or pressure imbalance can reduce cooling efficiency.
  
• Protects surrounding components, as leaking coolant can damage hoses, wiring, sensors, and engine bay parts.
  
• Restores reliable cooling system operation, ensuring overflow coolant is routed correctly back to the reservoir.
