Information
Water hose for cars with Tiptronic gearbox
High-quality OE Match coolant hose engineered to match the original Porsche specification for fit, flexibility, and durability. It is designed for the Porsche 996 (911) 1998–2005 with Tiptronic automatic transmission, and carries coolant within the engine’s cooling circuit to maintain proper operating temperatures. It installs directly in place of the original hose with no modification required, ensuring correct coolant flow and long-term service life.
Fits:
Porsche 996 C2 / C4 / C4S 1998 - 2005 Tiptronic Gearbox
Diagram ref no 33.
The Porsche 996’s water cooling system is responsible for regulating engine temperature under all driving conditions - from cold starts to high-speed touring. The water hose is a critical link in the coolant circuit, connecting key components such as the water pump, thermostat housing, radiator, and cylinder head.
Over time, heat cycling, pressure fluctuations, and environmental exposure cause hoses to age. Rubber can harden, swell, crack, or develop soft spots that lead to leaks, reduced coolant flow, or sudden failure. Because this hose operates under both thermal and pressure stress, deterioration can compromise cooling performance and increase the risk of engine overheating.
The water hose:
• Carries pressurised engine coolant between major cooling system components
• Maintains consistent coolant flow for stable temperature control
• Withstands heat, vibration, and pressure from the engine’s cooling system
• Helps prevent overheating and protects engine components
A compromised water hose can lead to:
• Coolant leaks
• Reduced heating efficiency
• Engine overheating
• Loss of pressure in the cooling circuit
Replacing old or degraded hoses with an OE Match water hose helps maintain coolant flow, preserves optimal engine temperatures, and prevents unexpected breakdowns due to hose failure.
Replace this water hose if you notice:
• Visible cracks, soft spots, or swelling
• Coolant leakage at hose ends
• Unexplained engine overheating
• During water pump or thermostat service
• As part of preventative maintenance on higher-mile vehicles
