Coolant hose kit for radiators by Kits for Porsche Cayenne 9PA (955) S, Turbo and Turbo S 4.5L, supplied as a matched set to support correct cooling system routing on selected models.
What This Product Does Coolant hoses link the engine, radiators and associated pipework so coolant can circulate and help keep operating temperatures within the intended range. A matched kit provides the key radiator hose pieces needed in one package for a consistent renewal of this part of the system.
Functions
- Route coolant between engine and radiators
- Support stable operating temperatures
- Help maintain coolant pressure integrity in the radiator circuit
- Group related hose parts for a coordinated replacement
Why Replacement Matters
Cooling system hoses and pipes age with heat cycles, pressure and coolant exposure. Rubber can harden or soften, plastic fittings may fatigue, and joints can begin to seep, particularly on older Cayenne models. Replacing ageing or suspect radiator hoses as a kit helps restore consistent coolant flow and pressure, reduces the risk of leaks developing at different times, and supports reliable temperature control. Proactive renewal is often chosen after signs of staining around joints, a persistent coolant smell or small leaks following hot use.

This OE Match water coolant bottom hose is a direct replacement for the original Porsche lower radiator hose fitted to Porsche 955 Cayenne 3.2L V6 models produced between 2003 and 2006. It forms part of the engine cooling system and transfers coolant between the radiator and engine cooling circuit to help maintain correct operating temperature and cooling efficiency.

The lower coolant hose transfers cooled coolant from the radiator back into the engine cooling system, helping maintain stable engine temperatures and efficient cooling system operation.
This hose is ideal for preventative cooling system maintenance, radiator servicing, or replacement during thermostat, water pump, or engine cooling repairs on Porsche 955 Cayenne V6 models.
Function
• Connects radiator to engine cooling circuit
• Transfers cooled coolant back to the engine
• Maintains stable engine operating temperature
• Supports efficient coolant circulation and pressure regulation
• Helps reduce risk of overheating and coolant loss
Cooling system hoses operate under constant heat, pressure, and vibration. Over time, hose material can deteriorate internally and externally, increasing the risk of leaks and cooling system pressure loss. A failed lower radiator hose may cause rapid coolant loss and engine overheating. Replacing worn coolant hoses helps maintain reliable cooling system performance and protects the engine from costly overheating damage.
When to replace
• Visible coolant leaks or staining
• Cracked, swollen, or brittle hose material
• Cooling system pressure loss
• Overheating or fluctuating coolant temperatures
• During radiator or thermostat replacement
• During preventative cooling system servicing

Radiator top and bottom hoses carry coolant between the engine and the radiator on Porsche models, helping to regulate operating temperature and support reliable running across everyday use and more demanding driving. OEMatch radiator top and bottom hoses are compatible replacements engineered to original-spec dimensions and tolerances — a practical option when genuine or OEM parts are unavailable.
Available Types- Moulded top hose and shaped bottom hose to match common Porsche coolant routing
- Reinforced rubber and fabric-wrapped constructions for higher temperature or pressure applications
- Complete hose assemblies including integrated fittings where applicable
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original radiator top and bottom hoses. OE (Original Equipment) refers to parts matching original specifications for the radiator top and bottom hoses and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM radiator top and bottom hoses engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Radiator hoses route hot coolant to the radiator and return cooled fluid to the engine; they are formed to fit around intake and accessory components and use clamps or quick-fit fittings to secure connections. OEMatch focuses on radiator top and bottom hose items selected for Porsche applications.
Benefits Include- Restored coolant flow and improved temperature stability
- Reduced risk of leaks and loss of coolant
- Materials chosen for heat resistance and flexibility to cope with engine movement
- Thermal ageing and repeated heat cycles cause rubber to harden and crack
- Chemical degradation from coolant additives can produce soft spots or swelling
- Abrasion, clamp wear or routing contact can lead to local damage and leaks
A failing hose can allow coolant loss and lead to overheating with risk to the engine. Replacing worn hoses maintains cooling circuit pressure and flow, supports stable engine temperature on Porsche models and reduces the chance of roadside breakdown. Fit the correct hose profile and use appropriate clamps or fittings to avoid leaks and ensure a reliable connection.
Advantages- Made to original-spec dimensions where applicable to aid fitment and routing
- Fits original mounting points and clearances to minimise refit work
- Available in multiple constructions to match repair needs and operating conditions
These items affect safety-critical systems. Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified.
