Diagram ref no 1

The bottom coolant hose transfers cooled coolant from the radiator back into the engine cooling circuit. This continuous coolant flow helps regulate engine temperature and prevents overheating during normal driving and high-load conditions.

Designed to withstand heat, pressure, and engine movement, the hose provides a secure and leak-free connection within the Porsche Cayenne cooling system

Functions & Technical Role
•  Coolant circulation: Transfers coolant between radiator and engine
•  Temperature regulation: Supports stable engine operating temperatures
•  Pressure resistance: Designed for high-pressure cooling systems
•  Leak prevention: OE moulded hose construction ensures proper sealing
•  OEM precision: Manufactured to Porsche factory specifications for exact fitment and reliability

Fitment / Position on Car
•  Fitting position: Lower radiator hose
•  Location: Between radiator and engine cooling system
•  System: Engine cooling / coolant circulation system

The lower radiator hose is constantly exposed to heat, coolant pressure, and engine movement. Over time, hoses can harden, crack, or swell, leading to coolant leaks and reduced cooling efficiency.

When to replace
•  Coolant leaks or seepage
•  Cracked, swollen, or brittle hose material
•  Cooling system pressure loss
•  During radiator or cooling system overhaul
•  Signs of overheating or coolant smell
