The radiator fan assembly for the Porsche Macan delivers reliable cooling performance with factory-correct airflow and fitment. Designed to prevent overheating and maintain stable engine temperatures, it ensures efficient radiator and A/C operation under all driving conditions. It includes the electric fan motor, fan blade, and the plastic shroud/cowling that mounts directly behind the radiator.
Fits:
Porsche 95B.1 3.0L / 3.6L Macan 2014 - 2018
Porsche 95B.2 2.9L / 3.0L Macan 2019 - 2021
Porsche 95B.3 2.9L / 3.0L Macan 2022>>

• Position on Vehicle: Installed at the front of the engine bay’s cooling system, the radiator fan with cowling sits behind the radiator and directs airflow across the coolant exchanger when the vehicle is at idle or under load.
• Cross-Reference / Alternative Numbers: OEM number: 95B 121 003 E (also listed as 95B121003E), related references: 95B 121 003 A/B/C and 95B 121 003.
• Applications: Ideal replacement when the original radiator fan assembly fails, exhibits reduced airflow, or during cooling-system upgrades where factory-equivalent performance is required.
A correctly functioning radiator fan is essential for maintaining engine temperature, particularly under load or high ambient heat. A degraded or damaged fan/shroud can lead to overheating, reduced coolant circulation, increased wear or potential engine stress. Replacing it restores correct cooling system behaviour, ensures consistent performance and contributes to long-term vehicle durability.
When and why to replace:
• Engine temperature fluctuates or rises unexpectedly when idling or in traffic.
• Fan motor runs intermittently, loudly or doesn’t activate when it should.
• Visible damage to the fan blades or cowling, loose mounting or excessive vibration.
• During a cooling system overhaul or when replacing radiator, hoses or cooling components.
• High mileage Macan where original fan may be showing signs of wear or aging.

Radiator for water coolant fluid (also known as Coolant radiator, Water radiator or Water coolant fluid cooler) is the backbone of a Porsche engine’s thermal management system. It dissipates heat from the engine’s water-based coolant, stabilising engine temperatures, preserving performance, efficiency, and long-term reliability.
Fits:
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2005 - 2008
Porsche 987C.2 Cayman 2009 - 2012
Porsche 997.1 Carrera 2005 - 2008
Porsche 997.1 GT3 2007 - 2009
Porsche 997.2 Carrera 2009 - 2012
Porsche 997.2 GT3 2010 - 2011
The radiator’s main role is to remove heat from the engine coolant that carries thermal energy away from the engine block and cylinder head. Hot coolant flows into the radiator, where it travels through a series of fine tubes and cooling fins. Air passing through the radiator core (from vehicle motion and fans) absorbs the heat, lowering coolant temperature before it returns to the engine.
Proper heat rejection helps:
• Maintain optimal engine operating temperature
• Prevent overheating under everyday and high-load conditions
• Support fuel efficiency and emission control
• Preserve engine component durability and longevity
