Please note: Before ordering, please check the part number in the vehicle.

Mounted in the front radiator section, this OEM fan works in conjunction with the control unit and temperature sensors to modulate fan speed according to engine load, vehicle speed and ambient conditions. Its precision-balanced blades, high-quality bearings and sealed motor ensure quiet, efficient operation and long service life.

Function:
• Provides Porsche-calibrated airflow through the radiator and condenser
• Maintains optimal coolant and engine temperatures under all driving conditions
• Operates quietly and smoothly to meet Porsche NVH and durability standards.

A degraded or failing cooling fan can compromise the entire thermal management system, leading to elevated coolant temperatures, reduced performance and potential long-term engine damage. Choosing a Genuine Porsche 9P1959455CY ensures the cooling system functions exactly as designed, with the correct airflow, control response and refinement expected from a modern 911 or 982-series car.

When to Replace:
• Overheating or rising temperatures at idle/low speed
• Fan no longer runs, or only runs intermittently
• Noticeably louder fan operation compared with normal
• Cooling system warnings or stored fan-related fault codes
• During front cooling module / radiator repairs where the old fan shows wear, impact damage or water ingress.
