NRF 47207 Radiator Fan

The NRF 47207 is a high‑performance electric motor cooling fan designed specifically for the Audi A4, A6, Allroad, C5, and B5 series. It serves as an essential component in maintaining optimal engine temperature by drawing air through the radiator core, thereby dissipating heat generated during operation.

Key Functional Features

• High‑Efficiency Airflow: Engineered to provide a robust airflow rate that matches or exceeds OEM specifications for the target Audi models. This ensures consistent cooling even under high load conditions.
• Durable Construction: Constructed from corrosion‑resistant materials and reinforced with heat‑tolerant bearings, the fan can withstand prolonged exposure to engine bay temperatures without degradation.
• Compact Design: The fan’s dimensions are tailored to fit within the tight clearance of Audi radiators, allowing for seamless installation in both front‑wheel‑drive and all‑wheel‑drive configurations.
• Integrated Shroud Compatibility: Compatible with OEM radiator shrouds (e.g., part number 4Z7959455), which help direct airflow efficiently across the heat exchanger surfaces.

Installation Overview

Installing the NRF 47207 involves removing the existing fan assembly, aligning the new unit with the radiator shroud, and securing it using the supplied mounting hardware. The fan’s electrical connector is designed to match the vehicle’s wiring harness, ensuring a straightforward plug‑and‑play connection.

Performance Metrics

Compatibility Matrix

The fan is specifically engineered for the following Audi models:

• Audi A4 (8D2) – 1.8 L, 1995‑2000
• Audi A6 (C5) – 2.5 L and 2.7 L variants
• Audi Allroad (B5) – 2.5 L and 2.7 L variants
• Other OEM vehicles using the same radiator shroud (4Z7959455)

Maintenance Tips

1. Visual Inspection: Periodically check for signs of wear on the fan blades and housing. Look for cracks, warping, or corrosion.
2. Electrical Check: Use a multimeter to verify continuity in the motor windings and ensure the connector pins are free from oxidation.
3. Lubrication: The fan’s bearings are sealed; however, if any play is detected, consider replacing the unit rather than attempting lubrication.
4. Cleaning: Gently wipe the fan blades with a soft cloth to remove dust buildup that could impede airflow.

Benefits Over Stock Components

• Enhanced cooling capacity leads to lower engine operating temperatures, which can improve fuel efficiency and reduce wear.
• Brushless motor design reduces noise levels compared to older brushed models.
• The fan’s robust construction offers a longer service life in demanding driving conditions.

Conclusion

The NRF 47207 Radiator Fan is a reliable, high‑performance replacement that aligns with Audi’s stringent OEM standards. Its engineered airflow, durable build, and compatibility with key models make it an ideal choice for anyone seeking to maintain or improve engine cooling performance in the Audi A4, A6, Allroad, C5, and B5 series.
