• Easy Installation: The fan’s design aligns with standard mounting points and electrical connections found on the original vehicle, allowing for straightforward swap without extensive modifications.
• Consistent Performance: Equipped with a reliable motor and robust bearings, the fan maintains steady operation across varying engine loads and ambient temperatures.

Technical Specifications

Installation Overview

The NRF 47402 fan is designed for a plug‑and‑play installation. The process typically involves:

1. Removal of the Existing Fan: Detach the old radiator fan by disconnecting electrical connectors and unscrewing mounting bolts.
2. Mounting the New Fan: Align the NRF 47402 with the existing mounting points, secure it with bolts, and reconnect the wiring harness.
3. Testing: Start the engine and verify that the fan engages correctly at idle and under load. Check for proper airflow and absence of vibration or noise.

Performance Benefits

• Enhanced Cooling Capacity: The fan’s optimized blade design increases airflow, reducing radiator temperature by up to 5 °C compared to standard fans.
• Reduced Engine Wear: By maintaining lower operating temperatures, the fan helps prevent thermal stress on engine components, extending overall durability.
• Improved Fuel Efficiency: Efficient cooling allows the engine to operate within its optimal temperature band, which can lead to modest gains in fuel economy.
• Noise Reduction: The fan’s balanced construction minimizes vibration, resulting in quieter cabin conditions during operation.

Maintenance Tips

Although the NRF 47402 is built for longevity, routine checks can ensure peak performance:

• Inspect Wiring: Periodically examine electrical connections for corrosion or loose contacts.
• Check Mounting Bolts: Tighten bolts to manufacturer specifications to prevent wobble.
• Clean the Fan Blades: Remove debris that may accumulate on blades, which can impair airflow.
• Verify Speed Control: Ensure the fan’s speed regulation responds correctly to engine temperature changes.

Compatibility Summary

The NRF 47402 radiator fan is suitable for a wide array of Volkswagen models, including but not limited to:

• Golf Mk2 & Mk3 (1988‑1999)
• Passat B1 & B2 (1988‑1996)
• Vento (1989‑1998)
• Corrado (1989‑1995)
• Caddy (1995‑2000)

Engine displacement compatibility ranges from 1.4 L to 2.0 L, covering both petrol and diesel variants.

Conclusion
