What This Part Does / Functions
•  Secures radiator and coolant hoses in position
•  Helps maintain a tight seal at hose connection points
•  Prevents coolant leaks caused by loose or weakened clamps
•  Supports correct cooling system pressure retention
•  Helps maintain coolant flow through the radiator circuit
•  Provides correct OE Porsche clamp size and fitment
•  Replaces a corroded, weakened, damaged or missing original clamp
•  Supports reliable engine cooling system operation.

Why Replace This Part?
Coolant hose clamps are exposed to heat cycles, coolant, moisture, road debris and engine bay vibration. Over time, a clamp can corrode, weaken, lose tension or become damaged during hose removal. A poor clamp can allow coolant seepage or hose movement, which may lead to coolant loss, low coolant warnings or overheating. Replacing it with a Genuine Porsche OE radiator coolant hose clamp helps ensure the hose is secured using the correct factory-specified clamp for the application.

When to Replace This Part
•   When replacing radiator coolant hoses
•   If the existing clamp is corroded, loose or damaged
•   If coolant seepage is present at the hose connection
•   During radiator, expansion tank or cooling system repairs
•   If the original clamp has lost tension
•   If the clamp was damaged during removal
•   During preventative cooling system overhaul
•   When restoring the vehicle with correct Genuine Porsche hardware.

Where It Fits on the Car
This clamp fits within the engine cooling system / radiator hose assembly. It is used to secure coolant hose connections at the radiator, expansion vessel or related water hose pipework depending on the specific Cayenne application.

Correct positioning is important to ensure the hose seats properly and seals without damage.
