OE Match radiator cooling duct and fan for selected Porsche 958 Cayenne 3.6L petrol and 3.0L Hybrid applications. This assembly combines the cooling-air duct with its fan, rather than being a coolant radiator.

Fits

• Porsche 958 Cayenne 3.6L 6-speed >>2014
  
• Porsche 958 Cayenne 3.0L HYBRID >>2014
  
  

Check fitment for your specific vehicle (model, year, engine) before ordering.

Diagram reference number 9

What This Product Does

The duct guides cooling air through the radiator area, while the fan supplies airflow when vehicle movement alone provides less air. It forms part of the engine-cooling assembly but does not replace the radiator core, coolant hoses or other fluid-carrying components.

Functions

• Directs air through the radiator area.
• Provides fan-assisted cooling airflow.
• Supports heat transfer from the radiator to the surrounding air.
  
  

Technical Details

• Assembly reference: 958121203A; identified as a cooling-air duct with fan.
• Associated supplied references: 95810606130, 95810606131 and 95810606140.
  
  

Symptoms of Fault

Increasing coolant temperature in traffic or intermittent overheating can warrant inspection of the cooling system, including its fan and air duct. These symptoms are not proof that this assembly has failed. Coolant loss, damp patches, staining or a sweet smell also require investigation of the radiator, hoses and connections.

Why Replacement Matters

A faulty fan or damaged air duct can interfere with radiator airflow. Replacement should follow diagnosis, with the surrounding cooling components inspected at the same time. OE Match focuses on Porsche replacement applications, using reference and specification checks within its product-development process.

FAQs

Is the coolant radiator included?
The supplied identification describes a duct-and-fan assembly. The diagram identifies the coolant radiator separately.

Does overheating confirm a fan fault?
No. Cooling-system leaks, restricted radiator flow and other faults can produce similar symptoms, so establish the cause before replacing parts.

What should be checked before selection?
Compare the original reference, model year, engine, transmission and applicable PR codes with the vehicle specification.

Radiator For Water Coolant.
The Porsche Water Coolant Radiator is a genuine engine cooling system component designed to dissipate heat from the engine coolant and maintain the correct operating temperature of the engine. Engineered to Porsche's exact specifications for fit, cooling efficiency and durability, this radiator plays a critical role in protecting the engine from overheating while ensuring optimum performance and reliability.  

Fits:

• Porsche 9YA Cayenne GTS V8 4.0L Petrol (460Hp) 2020-23
• Porsche 9YA Cayenne Coupe GTS V8 4.0L Petrol (460Hp) 2021-23
• Porsche 9YA Cayenne Turbo V8 4.0L Petrol (550Hp) 2020-23
• Porsche 9YA Cayenne Coupe Turbo V8 4.0L Petrol (550Hp) 2019-23
• Porsche 9YA.2 Cayenne S V8 4.0L Petrol (474Hp) 2023>>
• Porsche 9YA.2 Cayenne S Coupe V8 4.0L (474Hp) 2023>> 

 
Diagram Ref No 1

Constructed from high-quality aluminium with precision-engineered cooling fins and internal coolant passages, the radiator maximises heat transfer as coolant flows through the unit. Working in conjunction with the thermostat, cooling fans and water pump, it helps regulate engine temperature under all driving conditions, from everyday commuting to heavy-load and high-performance driving.  

What This Product Does:

• Dissipates heat from the engine coolant.
• Maintains correct engine operating temperature.
• Prevents engine overheating.
• Supports efficient coolant circulation throughout the cooling system.
• Helps maintain optimum engine performance and fuel efficiency.
• Protects critical engine components from heat-related damage.
• Works with cooling fans, thermostat and water pump to regulate temperature.
• Contributes to long-term engine reliability and durability.

Symptoms Of Wear Or Failure:

• Engine overheating or elevated coolant temperatures.
• Coolant leaks from the radiator core or end tanks.
• Low coolant level warnings.
• Visible corrosion or damage to the radiator fins.
• Coolant pooling beneath the vehicle.
• Reduced cooling system efficiency.
• Frequent overheating during traffic or heavy-load driving.
• Blocked or damaged cooling fins restricting airflow.
• Sweet coolant odour from the engine bay.
• Cooling system pressure loss.

Why Replacement Matters:

• The radiator is continuously exposed to coolant flow, pressure fluctuations, road debris, moisture, corrosion and temperature extremes. Over time, internal passages can become restricted, cooling fins may become damaged and corrosion can weaken the radiator structure, reducing its ability to dissipate heat effectively.
• A failing radiator can compromise cooling system performance, increasing the risk of engine overheating. Continued operation with inadequate cooling can lead to severe engine damage, including warped cylinder heads, damaged head gaskets and premature wear of internal engine components.
• Replacing a worn or damaged radiator restores proper cooling system efficiency, helps maintain stable operating temperatures and protects the engine from costly overheating-related damage. A genuine Porsche replacement ensures factory-correct fitment, optimal heat dissipation and long-term reliability, helping preserve the performance, efficiency and durability expected from your Porsche.
