What This Kit Does
The Porsche 991.1 GT3 and GT3 RS use a high-performance engine cooling system designed to maintain stable operating temperatures during demanding road and track driving.
The centre radiator helps dissipate heat from the circulating engine coolant, while the connecting hoses allow coolant to flow through the radiator assembly.
The upper and lower rubber mountings hold the radiator securely in position and help isolate vibration from the surrounding structure.
Replacing these components together helps restore the original cooling system arrangement.
Key Features
- Complete Genuine Porsche centre radiator replacement kit.
- Includes one centre water/coolant radiator.
- Supplied with left and right radiator coolant hoses.
- Includes two upper and two lower rubber mountings.
- Designed for first-generation Porsche 991 GT3 and GT3 RS models.
- Supports efficient coolant circulation and engine temperature control.
- Ideal for radiator repairs, cooling system refurbishment and track car maintenance.
- Original Porsche components for factory-specification fitment.
Why Replace This Kit?
Radiators and coolant hoses are exposed to repeated temperature changes, cooling system pressure, road debris and vibration.
Over time, the radiator core can become damaged or corroded, coolant hoses may deteriorate and rubber mountings can harden or split.
A damaged centre radiator or leaking hose can lead to coolant loss, reduced cooling efficiency and increased risk of engine overheating.
Replacing the radiator, hoses and mounting supports together helps avoid retaining worn components during a major cooling system repair.
Common Reasons for Replacement
- Coolant leaking from the centre radiator.
- Damaged or corroded radiator core.
- Cracked or deteriorated coolant hoses.
- Low coolant warning.
- Cooling system pressure loss.
- Damaged or compressed radiator rubber mountings.
- Front bumper or radiator impact damage.
- Reduced cooling efficiency during demanding driving.
- Complete centre radiator refurbishment.
Where It Fits on the Car
The kit fits within the front centre radiator assembly, located behind the front bumper. The radiator connects to the engine cooling system through the supplied left and right coolant hoses and is supported by the upper and lower rubber mountings.

This Porsche Genuine OE Radiator is the factory-specified water coolant radiator for the 2011–2018 Porsche Cayenne 4.8 L V8 platform. Designed for high-efficiency, high-durability performance, it plays a crucial role in maintaining engine thermal stability and ensuring reliable operation whether in daily use or spirited driving.

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

This radiator is the primary heat exchanger in the Cayenne’s cooling system. It circulates water-based engine coolant through a network of tubes and cooling fins, where heat from the engine is transferred into the surrounding air. By efficiently dissipating heat from the coolant, it maintains stable operating temperatures, prevents overheating, and helps protect internal engine components from thermal stress. Proper cooling also supports optimal fuel efficiency, emission control, and engine longevity.
Functions & Technical Role
• Primary coolant cooling: Transfers heat from hot coolant to the outside air.
• Overheat prevention: Keeps engine temperature within safe limits under daily and heavy driving conditions.
• Factory-matched design: Porsche-specified core size, fin density, and inlet/outlet alignment for exact fit.
• Durable construction: Built to withstand heat cycling, vibration, and road conditions encountered by the Cayenne platform
The radiator is critical to engine cooling - if the radiator becomes clogged, corroded, or damaged, engine temperatures can rise rapidly, leading to compromised performance, overheating, and even serious mechanical damage. Choosing a genuine Porsche OE radiator ensures correct fitment, thermal performance, and long-term reliability, avoiding the compromises that generic or mismatched cooling components can introduce.

* PR: D6V, D58, DT1, DT5
Diagram Ref No 1.
The radiator is the primary heat exchanger in the cooling system. Coolant heated by the engine flows through the radiator’s core, where airflow draws heat away before the coolant returns to the engine. This circulation:
• Maintains stable engine operating temperatures
• Prevents overheating under load or heat stress
• Supports efficient engine performance and emissions
• Ensures proper cabin heating when required
A failing or inefficient radiator can lead to engine overheating, poor climate control performance, coolant loss, and accelerated wear on other cooling system components. Symptoms such as rising temperature gauge readings, coolant leaks, or reduced heater output indicate that the radiator may no longer be functioning optimally. Replacing it with an OE Match radiator ensures reliable cooling performance and helps maintain engine health and longevity.
When to replace:
• Persistent engine overheating
• Visible coolant leaks or core corrosion
• Bent, damaged, or clogged cooling fins
• During front-end repair or cooling system service
• After water pump, thermostat, or main hose replacement
