The OE Match Radiator Water Fan is a replacement electric cooling fan designed for selected Porsche Cayenne 955 and 957 models.
Mounted within the radiator cooling assembly, the electric fan draws air through the radiator and associated heat exchangers when additional airflow is required. This is particularly important when the vehicle is stationary, travelling slowly or operating under conditions where natural airflow through the front of the vehicle is insufficient.
By increasing airflow through the radiator, the fan helps remove heat from the engine coolant and supports stable operating temperatures. It also contributes to cooling-system and air-conditioning performance under demanding conditions.
The OE-equivalent fan is the smaller of the two radiator cooling fans, with the original Porsche specification listed at 300W and incorporating the fan's electronic output-stage control module.

What This Product Does:
The radiator fan provides forced airflow through the cooling pack when vehicle speed alone does not provide sufficient air movement.
Its functions include:
- Drawing cooling air through the radiator.
- Helping remove heat from the engine coolant.
- Supporting stable engine operating temperature.
- Providing additional cooling when the vehicle is stationary.
- Increasing airflow during slow-speed driving.
- Supporting cooling during high ambient temperatures.
- Helping manage temperatures when the engine is under increased load.
- Supporting condenser airflow for the air-conditioning system.
- Working with the vehicle's electronic cooling controls to vary fan operation as required.
- Replacing a seized, noisy, damaged or electrically failed original fan.
The cooling system depends on both coolant circulation and airflow. Even with a good radiator and water pump, insufficient airflow can allow temperatures to rise when the vehicle is not moving quickly enough to force air through the radiator naturally.
Symptoms Of Wear Or Failure:
Possible symptoms include:
- Engine temperature rising while stationary.
- Temperature increasing in slow-moving traffic.
- Engine temperature returning towards normal once vehicle speed increases.
- Cooling fan failing to operate when required.
- Fan operating intermittently.
- Fan running only at certain speeds.
- Fan remaining permanently on.
- Excessive fan noise.
- Grinding or scraping noises from the fan motor.
- Squealing from the fan bearing area.
- Fan blades rotating slowly.
- Fan failing to reach normal speed.
- Visible wobble while the fan is operating.
- Damaged or cracked fan blades.
- Fan contacting its shroud.
- Cooling-system warning messages.
- Engine overheating.
- Air-conditioning performance becoming poor while stationary.
- Blown cooling-fan fuse.
- Electrical fault codes relating to fan control.
- Burnt electrical smell from the fan or control electronics.
These symptoms can also be caused by coolant-system, wiring, sensor or control faults, so proper diagnosis should be carried out before replacement.
Why Replacement Matters:
The electric fan is a critical part of maintaining correct engine temperature when airflow through the radiator is limited.
A weak or non-operational fan can allow coolant temperature to rise beyond the intended operating range.
Replacing a faulty fan helps restore:
- Correct radiator airflow.
- Stable engine temperature.
- Reliable low-speed cooling.
- Improved cooling during idling.
- Correct air-conditioning condenser airflow.
- Consistent electronic fan control.
- Reduced risk of overheating.
- Reliable operation of the complete cooling system.

This radiator functions as the primary heat exchanger in the Porsche Panamera’s cooling system. It transfers heat from the hot engine coolant into the surrounding air, helping maintain stable engine operating temperatures. Efficient cooling supports power delivery, emission control, and engine longevity - especially under everyday driving and high-load conditions. A properly functioning radiator also reduces the risk of overheating, prevents needless stress on engine components, and contributes to consistent performance.

The radiator is the heart of the engine’s liquid cooling system, responsible for removing heat from the engine coolant before it returns to the engine. As hot coolant flows through the radiator’s core, heat is transferred to the air passing through the cooling fins, helping maintain ideal engine operating temperatures. Proper cooling prevents overheating, supports consistent performance, protects internal engine components from heat stress, and helps maintain fuel efficiency and emission control.

The water/coolant radiator serves as the cooling system’s primary heat exchanger, where hot coolant from the engine is cooled by airflow before being circulated back into the engine. This process helps:
• Maintain stable engine temperature
• Prevent overheating under load
• Improve heater and climate control performance
• Protect engine components from thermal stress
• Support efficient combustion and emissions control
A failing radiator can lead to engine overheating, coolant loss, performance penalties, and - in extreme cases - engine damage. Symptoms of radiator issues include rising temperature gauge readings, coolant leaks under the vehicle, reduced heater output, and visible core damage. Replacing an inefficient or damaged radiator with an OE Match unit restores effective cooling capability and helps maintain the Porsche Panamera’s performance and drivetrain health.
When to replace:
• Persistent engine overheating or temperature spikes
• Visible radiator leaks, punctures, or core corrosion
• Bent, clogged, or damaged cooling fins
• After front-end impact or collision
• During cooling system overhaul (water pump, thermostat, hoses)
