NRF 47245 Fan, radiator

Overview

The NRF 47245 Fan, radiator is a high‑performance cooling solution engineered to keep engine temperatures within safe limits under a wide range of operating conditions. Designed for use in compact and mid‑size vehicles, this fan delivers reliable airflow while maintaining low noise levels and high durability.

Design & Build Quality

The fan features a compact aluminum housing that resists corrosion and heat buildup. Its sealed bearing system ensures smooth operation over thousands of operating hours, even in harsh environments. The integrated thermal sensor interface allows the vehicle’s ECU to regulate fan speed automatically based on coolant temperature.

Compatibility

The NRF 47245 is engineered for a broad range of engines, particularly those found in Fiat Punto, Lancia Ypsilon, and similar models. Its mounting flange matches standard radiator designs, making it a drop‑in replacement for many OEM fans. The fan’s dimensions (approx. 120 mm diameter) fit within the typical engine bay clearance of compact cars.

Performance Characteristics

• Airflow Capacity: Approximately 200 CFM at full speed, providing ample cooling for engines up to 1.5 L displacement.
• Noise Level: ≤ 60 dB(A) during normal operation, thanks to optimized blade geometry and vibration damping.
• Operating Speed: Variable speed control from 0–3000 RPM, enabling the ECU to match cooling demand precisely.
• Power Consumption: ≤ 200 W, keeping electrical load within typical vehicle specifications.

Installation Guide

The fan can be installed by following these steps:

1. Disconnect the battery to ensure safety.
2. Remove the existing radiator fan assembly, noting the orientation of wiring harnesses and mounting bolts.
3. Align the NRF 47245’s mounting flange with the radiator support and secure it using the supplied hardware.
4. Reconnect the electrical connector, ensuring a firm connection to the vehicle’s ECU or dedicated fan control module.
5. Verify that the fan spins freely without obstruction before re‑attaching any covers.

Maintenance & Longevity

Routine checks should include:

• Visual Inspection: Look for signs of wear, corrosion, or debris on blades and housing.
• Bearing Lubrication: If the fan is a non‑sealed model, apply high‑temperature grease every 20,000 km.
• Electrical Connections: Ensure connectors are clean and free of oxidation; replace any damaged wiring.

When properly maintained, the NRF 47245 can exceed 50,000 km of service life without performance degradation.

Technical Specifications

Frequently Asked Questions

What vehicles can use the NRF 47245?

The fan is designed for compact and mid‑size cars, especially those with 1.0–1.5 L engines such as Fiat Punto, Lancia Ypsilon, and similar models.

Is the fan compatible with aftermarket radiators?

Yes, as long as the radiator’s mounting flange matches standard dimensions, the NRF 47245 can be installed without modification.

Can I use a higher‑power fan instead?

While higher power fans exist, they may exceed the vehicle’s electrical capacity and produce excessive noise. The NRF 47245 balances performance with reliability for its target applications.

How do I know if my fan is failing?

Signs include increased engine temperature, abnormal noise, or a noticeable drop in airflow. If these symptoms appear, inspect the fan blades and bearings before replacing the unit.
