NRF 47379 Radiator Fan

The NRF 47379 is a high‑performance radiator fan designed specifically for Toyota vehicles such as the Auris and Corolla models. It plays a crucial role in maintaining optimal engine temperature by drawing air through the cooling system, thereby preventing overheating during both normal operation and demanding driving conditions.

Key Functional Features

• Engine Cooling Efficiency: The fan is engineered to provide consistent airflow across a wide range of engine speeds, ensuring that coolant remains within the ideal temperature window even under heavy load or high ambient temperatures.
• Durable Construction: Constructed from reinforced aluminum and heat‑resistant plastic components, the fan withstands prolonged exposure to hot coolant, oil, and exhaust gases without degradation.
• Low Noise Operation: Precision bearings and balanced blades reduce vibration, resulting in a quiet operation that does not interfere with cabin comfort.
• Compact Design: Its streamlined shape allows for easy installation within the tight confines of modern engine bays while maintaining full compatibility with existing mounting brackets.

Compatibility Overview

The NRF 47379 is tailored to fit a range of Toyota models and engine configurations. Below are the primary vehicle families and engine types for which this fan is an exact match:

• Auris Series (2007‑2012): 1.4L 4ZZ-FE, 1.6L 1ZR-FE/FAE, 1.8L 2ZR-FAE, 1.3L 1NR-FE.
• Corolla Series (2006‑2014): 1.4L 4ZZFE, 1.3L 1NRFE, VVT-i variants.
• Engine Variants: Dual VVT-i 1.3L, Valvematic 1ZRFAE 1.6L, and other 4‑cylinder petrol engines within the specified model years.

Because the fan is a genuine OEM part, it aligns perfectly with factory specifications for airflow, mounting points, and electrical connections, ensuring seamless integration without the need for adapters or modifications.

Installation Highlights

• Mounting: The fan attaches to the existing radiator support brackets using standard bolts. No additional hardware is required beyond what is already present in the vehicle.
• Electrical Connection: A single plug connects to the engine control module (ECM) wiring harness, allowing the fan to respond automatically to temperature sensor inputs.
• Removal and Replacement: The design facilitates quick removal for maintenance or replacement. Users can swap the fan without affecting other cooling system components.

Performance Metrics

The NRF 47379 delivers a measured airflow of approximately 250 CFM (cubic feet per minute) at peak RPM, which is sufficient for maintaining coolant temperatures under most operating conditions. Its thermal resistance rating ensures that the fan continues to function effectively even when ambient temperatures approach 120°F.

Maintenance Tips

• Inspect the fan blades and housing annually for signs of wear or corrosion.
• Check electrical connections for tightness and clean any debris that may impede airflow.
• Replace the fan if you notice unusual vibrations, excessive noise, or a drop in cooling performance.

Why Choose the NRF 47379?

Opting for this OEM radiator fan guarantees:

• Reliability: Proven track record across multiple Toyota models.
• Compatibility: Exact fit with factory mounting points and wiring.
• Longevity: Built to endure the demanding thermal environment of automotive engines.

The NRF 47379 radiator fan is an essential component for anyone looking to preserve engine health, improve cooling efficiency, and ensure consistent performance across a wide range of driving scenarios.
