NRF 47351 Fan, radiator

NRF 47351 Radiator Fan

The NRF 47351 radiator fan is a high‑performance cooling component designed for use in the engine compartments of popular commercial and passenger vehicles such as Citroën, Fiat, Peugeot, and their various derivatives (Boxer, Relay, Ducato, Jumper). This fan is engineered to maintain optimal coolant temperatures under heavy load conditions, ensuring reliable engine operation and extending component life.

Key Functional Characteristics

• High airflow capacity: Generates a substantial volume of air through the radiator core, enhancing heat dissipation even during prolonged idling or high‑speed driving.
• Durable construction: Made from reinforced aluminum alloy and high‑strength plastic housing to resist corrosion, vibration, and thermal fatigue.
• Integrated motor control: Equipped with a built‑in speed controller that adjusts fan revolutions based on coolant temperature sensors, providing efficient power usage.
• Low noise operation: Precision-balanced blades reduce acoustic signatures, making it suitable for both commercial fleets and passenger vehicles where cabin quietness is valued.

Compatibility Overview

The NRF 47351 fan is a direct OEM replacement for a wide range of models. Below are the primary vehicle families and engine codes that this part supports:

Because the fan is a direct fit for these engines, no modifications to the radiator or mounting brackets are required.

Installation Guide

1. Disconnect battery to prevent accidental electrical contact while working on the cooling system.
2. Remove the existing fan by loosening the mounting screws and disconnecting the wiring harness. Keep the connector in a safe place for re‑attachment.
3. Align the new NRF 47351 fan with the mounting holes, ensuring that the blade orientation matches the original installation to maintain airflow direction.
4. Screw the fan into place using the supplied bolts and torque specifications (typically 10–12 Nm).
5. Reconnect the wiring harness, verifying correct polarity and secure contact.
6. Re‑install any protective covers or shields that were removed during removal.
7. Reconnect the battery and start the engine. Observe coolant temperature gauge to confirm proper fan operation.

Performance Benefits

• Consistent cooling: Maintains lower coolant temperatures, reducing thermal stress on pistons, valves, and head gaskets.
• Improved fuel efficiency: By keeping the engine within optimal temperature ranges, combustion efficiency is maximized.
• Extended component life: Lower operating temperatures decrease wear on bearings, seals, and other moving parts.
• Reliability in extreme conditions: Designed to function reliably in high ambient temperatures and heavy traffic scenarios typical of commercial fleets.

Maintenance Tips

Although the NRF 47351 fan is built for longevity, routine checks can pre‑empt failures:

• Inspect blade alignment monthly; misalignment can cause vibration.
• Check electrical connections for corrosion or loose contacts.
• Verify that the fan speed controller responds correctly to coolant temperature changes.
• Replace any damaged housing panels promptly to avoid water ingress.
