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.

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

It’s ideal as a cost-effective replacement when the factory fan has become noisy, weak, or failed completely.

Function:
• Draws air through the radiator and condenser to assist engine cooling
• Supports stable coolant temperatures at idle, low speeds and high load
• Integrates with the vehicle’s fan control strategy for staged or variable-speed operation.

Over time, cooling fans are subjected to heat, vibration and moisture, which can wear motor bearings, damage windings or throw the fan out of balance. A weak or failing fan can’t move enough air, causing rising coolant temperatures, especially in slow traffic or on hot days. Replacing it with a properly spec’d OE-Match unit restores consistent cooling performance and helps protect the engine from overheating.

When to Replace:
• Coolant temperature climbs at idle or in traffic
• Fan runs noisily (grinding, humming or excessive vibration)
• Fan fails to start even when the engine is hot
• Intermittent fan operation or related fault codes
• Radiator/condenser replacement where the old fan shows wear or damage.
