Water Coolant Hose. Porsche 95B.1 Macan 2.0L 2014-18  ❭  95B121056

Water Coolant Hose.
The OE Match Water Coolant Hose is a high-quality replacement cooling system component designed to transport engine coolant between key cooling system components while maintaining a sealed, pressurised circuit. Manufactured to OE specifications for fit, flexibility and durability, this coolant hose ensures efficient coolant circulation to help maintain the correct engine operating temperature under all driving conditions.  

Fits:

Diagram Ref No 22

Constructed from premium-quality reinforced rubber with heat- and pressure-resistant materials, the hose is engineered to withstand continuous exposure to hot coolant, engine vibration and fluctuating operating pressures. Precision-moulded to match the original routing and connection points, it provides secure installation and reliable leak-free performance.  

What This Product Does:

• Transfers coolant between engine cooling system components.
• Maintains efficient coolant circulation throughout the cooling system.
• Helps regulate engine operating temperature.
• Supports effective heat transfer through the radiator.
• Provides secure, leak-free coolant flow under pressure.
• Works with the water pump, thermostat and radiator to optimise cooling.
• Protects the engine from overheating.
• Contributes to long-term engine reliability and performance.

Symptoms Of Wear Or Failure:

• Coolant leaks around the hose or hose connections.
• Low coolant level warnings.Engine overheating.
• Cracks, splits or perishing of the hose material.
• Swollen, soft or excessively hardened hose sections.
• Coolant odour from the engine bay.
• White or coloured coolant residue around the hose.
• Bulging or collapsed hose under pressure.
• Steam escaping from the engine compartment.
• Reduced heater performance due to coolant loss or restricted flow.

Why Replacement Matters:

• Coolant hoses operate under constant pressure and are continually exposed to high temperatures, engine vibration, coolant chemicals and environmental ageing. Over time, the rubber material can harden, crack, swell or lose its structural integrity, increasing the risk of coolant leaks or sudden hose failure.
• A failed coolant hose can rapidly reduce coolant levels and compromise the engine's ability to regulate temperature. Continued driving with insufficient coolant circulation may result in severe engine overheating, potentially causing warped cylinder heads, head gasket failure and costly internal engine damage.
• Replacing a worn or damaged coolant hose restores reliable coolant circulation and maintains the integrity of the engine cooling system. An OE Match replacement provides factory-style fitment, dependable sealing performance and long-lasting durability, helping preserve the performance, efficiency and reliability expected from your Porsche.
