Constructed from premium multi-layer reinforced EPDM rubber, the hose is engineered to withstand high coolant pressures, extreme temperature fluctuations, engine vibration and long-term exposure to coolant. Precision-moulded to match the original factory routing, it provides direct OE-style fitment and dependable, leak-free performance.  

What This Product Does:

• Transfers coolant between engine cooling system components.
• Maintains continuous coolant circulation.
• Helps regulate engine operating temperature.
• Supports efficient heat dissipation from the engine.
• Provides a secure, leak-free coolant connection.
• Withstands high pressure and temperature changes.
• Helps prevent engine overheating.
• Forms an essential part of the vehicle's cooling system.

Symptoms Of Wear Or Failure:

• Visible coolant leaks.
• Cracked, split or swollen hose.
• Soft, brittle or deteriorated rubber.
• Coolant smell from the engine bay.
• Low coolant level.Engine overheating.
• White, pink or blue coolant residue around hose connections.
• Bulging hose when under pressure.
• Steam from the engine compartment.
• Coolant warning light or frequent coolant top-ups.

Why Replacement Matters:

• Coolant hoses operate in demanding conditions, where they are exposed to constant pressure cycles, hot coolant, engine vibration and changing temperatures. Over time, the rubber can harden, crack or weaken, while the internal reinforcement may deteriorate, increasing the risk of coolant leaks or sudden hose failure.
• A leaking or burst coolant hose can quickly reduce coolant levels, leading to engine overheating and potentially severe engine damage, including cylinder head distortion, head gasket failure and premature wear of internal engine components. Even a minor leak can reduce cooling system efficiency and result in costly repairs if left unattended.
• Replacing a worn or damaged coolant hose restores the integrity of the cooling system and ensures reliable coolant circulation. The OE Match replacement provides factory-style fitment, premium-quality materials and long-lasting durability, helping maintain optimum engine temperature, improve reliability and protect the performance and longevity of your Porsche.
