Manufactured from high-quality reinforced rubber with heat-resistant construction, the hose is designed to withstand high coolant pressures, temperature fluctuations and continuous exposure to engine bay conditions. Precision-moulded to match the original routing, it ensures secure connections and leak-free performance throughout the cooling system.  

What This Product Does:

• Transfers coolant between engine cooling system components.
• Maintains efficient coolant circulation throughout the engine.
• Helps regulate engine operating temperature.
• Supports effective heat transfer to the radiator.
• Prevents coolant loss through secure, sealed connections.
• Works with the water pump, thermostat and radiator to optimise cooling.
• Protects the engine from overheating.
• Contributes to reliable engine performance and longevity.

Symptoms Of Wear Or Failure:

• Coolant leaks around the hose or connection points.
• Low coolant level warnings.Engine overheating.
• Visible cracks, swelling or soft spots in the hose.
• Coolant odour from the engine bay.
• White or coloured coolant residue around hose connections.
• Bulging or collapsed hose sections.
• Steam from the engine compartment.
• Reduced heater performance due to coolant loss.
• Cooling system pressure loss.

Why Replacement Matters:

• Engine coolant hoses are continuously exposed to hot coolant, pressure fluctuations, engine vibration and harsh under-bonnet temperatures. Over time, the rubber material can harden, crack, swell or weaken, while the internal reinforcement may deteriorate, increasing the risk of leaks or sudden hose failure.
• A damaged coolant hose can cause coolant loss, reduced cooling efficiency and engine overheating. If left unresolved, overheating can result in serious engine damage, including warped cylinder heads, head gasket failure and premature wear of critical engine components.
• Replacing a worn or damaged coolant hose restores proper coolant circulation and maintains the integrity of the engine cooling system. A genuine Porsche replacement ensures factory-correct fitment, dependable sealing and long-term durability, helping preserve the performance, reliability and longevity expected from your Porsche.
