Water Hose, 18 X 3,5 X 50.
The Genuine Porsche Water Hose 90018106250 is a short coolant connector hose used within the water-cooling circuit associated with the Tiptronic automatic-transmission heat exchanger on selected Porsche Boxster and Cayman models.

Although positioned within the transmission-cooling system, this hose carries engine coolant rather than automatic transmission fluid.
Coolant circulating through the ATF heat exchanger transfers heat between the engine cooling system and the automatic transmission fluid, helping the transmission reach and maintain an appropriate operating temperature.
Because the hose operates as part of the pressurised engine cooling system, it must remain flexible, securely clamped and completely leak-free.
Age, heat, coolant exposure and repeated pressure cycles can eventually cause the rubber to harden, swell, crack or lose its ability to seal correctly.
Replacing a deteriorated hose helps restore coolant-system integrity and reduces the risk of coolant loss, transmission heat-exchanger problems and engine overheating.
What This Product Does:
This hose provides a short flexible coolant connection within the Tiptronic transmission oil-cooling circuit.
Its functions include:
- Carrying engine coolant through the transmission heat-exchanger circuit.
- Maintaining coolant circulation around the ATF cooler.
- Helping regulate automatic-transmission fluid temperature.
- Maintaining a sealed and pressurised cooling circuit.
- Providing flexibility between adjoining rigid coolant components.
- Accommodating vibration and thermal movement.
- Preventing coolant loss at the connection.
Symptoms Of Wear Or Failure:
Common symptoms include:
- Visible coolant leakage.
- Coolant residue around the hose.
- Damp hose connections.
- Gradual loss of coolant.
- Low-coolant warning.
- Sweet coolant smell.
- Drips beneath the vehicle.
- Cracked rubber.
- Hardened hose material.
- Soft or swollen rubber.
- Bulging.
- Leakage around the hose clamps.
- Engine temperature rising above normal.
- Steam following a major coolant leak.
Why Replacement Matters:
Replacing a worn or leaking water hose helps restore:
- Cooling-system sealing.
- Correct coolant circulation.
- Proper system pressure.
- Reliable ATF heat-exchanger cooling.
- Stable engine operating temperature.
- Reduced risk of coolant loss.
- Long-term cooling-system reliability.
A small coolant hose is inexpensive compared with the potential consequences of major coolant loss or overheating.
