Coolant Hose With Vacuum Valve. Porsche 958 Cayenne 3.0L Hybrid 2010-14  ❭  95810637402

Coolant Hose With Vacuum Valve.
Maintain precise coolant flow and system control with the Coolant Hose with Vacuum Valve. This OEM-quality assembly combines a coolant hose with an integrated vacuum-controlled valve, allowing regulated coolant circulation within the engine cooling system.

Fits:

• Porsche 958 Cayenne S V6 3.0L Hybrid (380Hp) 2010-17

Diagram Ref No 10

What This Product Does:

• Carries coolant between cooling system components
• Uses a vacuum valve to control coolant routing or flow
  
• Helps maintain stable engine operating temperature
• Improves cooling system efficiency based on engine conditions
• Supports proper heat management and prevents overheating

Symptoms Of Wear Or Failure:

• Coolant leaks near the hose or valve assembly
  
• Low coolant warning light
• Frequent coolant top-offs
• Engine overheating or rising temperature gauge
  
• Coolant residue or dampness around valve connections
  
• Sweet coolant smell from the engine bay
  
• Cracked, swollen, or brittle hose material
• Valve not opening/closing properly, affecting coolant circulation
  
• Erratic engine temperature changes
• Poor heating or cooling system performance
• Vacuum-related fault codes / check engine light (in some cases)
  
  

Why Replacement Matters:

• Replacing a worn coolant hose with an integrated vacuum valve is important because it affects both coolant circulation and the system’s ability to regulate engine temperature. Over time, the hose can crack or leak, and the vacuum valve may fail, stick, or stop responding correctly.
• If this part fails, coolant flow may be restricted or misrouted, which can lead to overheating, unstable temperature control, and reduced cooling system efficiency. Coolant leaks can also cause rapid coolant loss and serious engine damage if left unaddressed.
• Installing a new hose and valve assembly helps restore proper coolant routing, prevent leaks, maintain stable operating temperatures, and protect the engine for long-term reliability.
