Engine Coolant Hose, Feed. Porsche 957 Cayenne S / GTS / Turbo / Turbo S 4.8L 2007-10  ❭  94810645702

Engine Coolant Hose, Feed.
The Engine Coolant Hose, Feed OE MATCH coolant hose designed to carry pressurised engine coolant through the feed side of the cooling system. This hose ensures correct coolant circulation between key cooling components, helping maintain stable engine operating temperatures and reliable cooling performance. It provides precise fitment, durability, and long-term resistance to heat and pressure for Porsche 957 models.

Fits:

• Porsche 957 Cayenne S/GTS 4.8L 2007-10

Diagram Ref No 4 (Diagram Ref No 5 And 6 Sold Separately)

What This Product Does:

• Feeds engine coolant between major cooling components such as the engine, radiator, oil cooler, or expansion tank.
  
• Helps maintain proper coolant circulation and pressure, which is essential for engine temperature control.
  
• Prevents overheating by ensuring coolant flows efficiently through the system.
  
• Provides a flexible connection that absorbs engine movement and thermal expansion without stressing rigid pipes.
  
  

Symptoms Of Wear Or Failure:

• Coolant may leak from the hose itself or around the hose clamp connections, often leaving wet residue or staining.
• A deteriorating feed hose can cause gradual coolant loss, requiring frequent top-ups.
• If coolant flow is reduced due to a leak or internal collapse, the engine temperature may rise or fluctuate.
• A noticeable sweet smell in the engine bay or around the vehicle often indicates a coolant leak.
• Common signs include cracking or splitting, swelling or bulging, soft spots or hardened rubber, coolant residue on the hose surface.
  
• If coolant circulation is compromised, the heater core may not receive enough hot coolant.
• Modern Porsche vehicles may display low-coolant or overheating warnings when hose failure begins.

Why Replacement Matters:

• Prevents coolant leaks that lead to low coolant levels and loss of system pressure.
  
• Helps avoid engine overheating, which can cause severe and costly engine damage.
  
• Restores proper coolant circulation, ensuring efficient heat removal under all driving conditions.
  
• Maintains reliable heater performance, since cabin heat depends on steady coolant flow.
  
• Protects surrounding components, as leaking coolant can damage sensors, wiring, hoses, and seals.
