Radiator water with hoses, Centre. Porsche 958 Cayenne 4.8L 2011-18  ❭  RADANDPIPEKIT958.V8.OEM

Radiator water with hoses. Centre.
This OE Match cooling system kit is a complete radiator and hose assembly engineered to refresh the core water/coolant circuit for the Porsche Cayenne 958 4.8 L from 2011 through 2018. It combines an OE Match radiator with precisely matched coolant hoses, genuine radiator mounts, and genuine hose clamps - everything needed to restore proper coolant flow and engine thermal management in one convenient package.

Fits:
Porsche 958 Cayenne 4.8L S / GTS / Turbo 2011 - 2018
* PR: D6V, D58, DT1, DT5

The cooling system in high-performance SUVs like the Cayenne 4.8 L must manage significant heat generated by the V8 engine, especially during heavy load, highway driving, towing, or hot ambient conditions. Over time, radiator cores can lose efficiency and material integrity, and hoses can harden, swell, or crack, leading to leaks or reduced coolant circulation.

This kit forms the core of the Cayenne’s coolant circulation loop at the centre radiator position. The radiator dissipates engine heat through airflow while the hoses route coolant in and out of the heat exchanger. Proper function of these components maintains optimal engine temperature, prevents overheating, supports heater performance, and protects critical components like cylinder heads, head gaskets, and turbocharger interfaces from thermal stress.

Function
•  Radiator: Transfers heat away from coolant to ambient air
•  Coolant Hoses: Provide secure, leak-free coolant routing
•  Mounts: Secure radiator in place with correct vibration isolation
•  Clamps: Ensure watertight connections under pressure and thermal cycling

Over time, radiator cores and coolant hoses degrade from heat cycling, pressure fluctuations, and environmental exposure. A weakened radiator or aging hoses can cause coolant leaks, overheating, inconsistent temperature readings, heater performance issues, and increased stress on the engine cooling network. Replacing these components as a matched kit increases reliability, restores cooling efficiency, and reduces the risk of roadside breakdowns and expensive engine repairs.

When to replace:
•  Coolant leaks at the radiator or hose joints
•  Frequent temperature gauge fluctuations
•  Hose bulging, cracking, or soft spots
•  Bent, collapsed, or clogged radiator fins
•  During scheduled cooling system service
•  After front-end collision or coolant system work
