Information
Water coolant hose, supply
This original Porsche coolant hose forms part of the engine cooling system, helping route coolant through the supply side of the cooling circuit and maintain correct engine temperature control.
Fits:
Porsche 997.1 2005 - 2008
Porsche 997.2 2009 - 2012
Diagram ref no 17
This hose is used in the water cooling system on selected Porsche 997 models.
What This Part Does / Functions:
• Routes coolant through the supply side of the engine cooling system
• Helps maintain correct coolant flow and operating temperature
• Connects specified cooling system components where fitted
• Helps prevent coolant loss when correctly sealed and installed
• Replaces a cracked, swollen, leaking or heat-damaged original hose
• Provides correct OE Porsche hose shape, material and connection fitment
• Supports reliable cooling system operation.
Why Replace This Part?
Coolant hoses are exposed to heat cycles, coolant pressure, engine bay temperatures, vibration and age-related rubber deterioration. Over time, the hose can harden, swell, crack, split or leak. A failing coolant supply hose may cause coolant loss, low coolant warnings, overheating risk or visible coolant residue around the hose connections.
Replacing it with an OE Genuine Porsche water coolant supply hose helps restore the correct factory coolant routing and reliable cooling system sealing.
Common Symptoms of a Faulty Coolant Supply Hose
• Coolant leak from the hose or hose connections
• Dried coolant residue around the cooling system
• Low coolant warning
• Coolant smell from the engine bay
• Engine temperature rising above normal
• Hose swelling, cracking or softening
• Coolant pressure loss
• Damage found during cooling system inspection.
When to Replace This Part
• If the original coolant hose is cracked, swollen, leaking or damaged
• During cooling system overhaul
• When replacing related coolant pipes, water pump, thermostat or radiator components
• If coolant loss is traced to this hose
• After engine bay service where the hose has been disturbed
• If the hose has become brittle or oil-contaminated
• During preventative maintenance on older cooling systems
• When restoring the cooling system with OE Genuine Porsche parts.
Where It Fits on the Car
This hose fits in the engine cooling / water cooling system of the Porsche 997. It is identified as a supply-side coolant hose and is shown in Porsche cooling diagrams as diagram reference no. 17.
Correct routing, clamp positioning and sealing are important to prevent coolant leaks and maintain proper cooling system operation.
