Product Information
Product Information
Cooling Water Tube.

The Cooling Water Tube is a OE MATCH coolant pipe designed to route engine coolant through the vehicle’s cooling and heating system. This rigid water tube helps maintain correct coolant circulation between key cooling components, supporting stable engine operating temperatures and reliable heater performance. It provides precise fitment and long-term durability for Porsche 970 Panamera models.

Fits:

  • Porsche 970.1 Panamera V6 3.6L 2WD 2009-13
  • Porsche 970.1 Panamera 4 V6 3.6L 4WD 2009-13
  • Porsche 970.2 Panamera V6 3.6L 2WD (310Hp) 2014-16
  • Porsche 970.2 Panamera 4 V6 3.6L 4WD (310Hp) 2014-16

What This Product Does:

  • Routes engine coolant through the cooling circuit to support proper circulation.
  • Helps regulate engine operating temperature by ensuring coolant flows efficiently through the system.
  • Supports the heater system, since cabin heating depends on hot coolant being circulated through the heater core.
  • Provides a rigid, stable coolant pathway, reducing the risk of hose collapse or kinking in tight routing areas.

Symptoms Of Wear Or Failure:
  • Coolant may seep or drip from the tube itself or from the joints where hoses connect, often leaving residue or staining.
  • A failing tube can cause gradual coolant loss, leading to frequent top-ups.
  • Leaks or internal restrictions can disrupt coolant circulation, causing rising or fluctuating engine temperatures.
  • A noticeable sweet smell in the engine bay is a common sign of a coolant leak from the tube.
  • Because it’s a rigid pipe, wear often appears as corrosion or pitting, cracking, weakened areas near joints or mounting points
  • If coolant flow is compromised, the heater core may not receive enough hot coolant, resulting in poor heater performance.
  • Modern Porsche models may trigger low-coolant or overheating warnings if the tube begins to fail.

Why Replacement Matters:
  • Prevents coolant leaks that can lead to low coolant levels and loss of system pressure.
  • Helps avoid engine overheating, which can cause severe and expensive engine damage.
  • Restores proper coolant flow, ensuring the cooling system works efficiently under all driving conditions.
  • Maintains reliable heater performance, since cabin heat depends on hot coolant reaching the heater core.
  • Protects surrounding components, because leaking coolant can damage hoses, sensors, seals, and nearby engine parts.
