NRF 47305 Fan, radiator

NRF 47305 Fan – Radiator Cooling Solution

The NRF 47305 Fan is a high‑performance radiator cooling fan designed specifically for the Nissan Murano and other vehicles equipped with the VQ35DE 3.5 L engine. This fan delivers reliable airflow, ensuring optimal engine temperature control even under demanding driving conditions.

Key Features

• Power: 250 W – sufficient to drive a robust 344 mm fan blade set.
• Voltage: 12 V DC – compatible with standard automotive electrical systems.
• Dimensions: Approx. 344 mm diameter, engineered for tight engine bay spaces.
• Construction: Heavy‑duty aluminum housing with reinforced fan blades to resist vibration and thermal expansion.
• Mounting: Includes a complete mounting frame (bastidor) that aligns precisely with the Nissan Murano radiator support structure.
• Cooling Efficiency: Dual‑stage airflow design enhances heat dissipation from the engine block, cylinder head, and coolant passages.

Compatibility Overview

The NRF 47305 Fan is engineered for the following vehicle models and configurations:

• Nissan Murano I (Z50) – 2003‑2008 model years with a 3.5 L V6 engine.
• All Nissan Murano variants equipped with the VQ35DE powerplant.
• Vehicles requiring a 344 mm, 12 V, 250 W radiator fan for optimal cooling performance.

Because of its standardized mounting frame and electrical connector layout, the fan can be swapped into any compatible Nissan engine bay with minimal adjustments.

Installation Guide

1. Disconnect Battery: For safety, remove the negative battery terminal before working on the cooling system.
2. Remove Existing Fan: Unscrew the mounting bolts that secure the current fan to the radiator support. Carefully detach the electrical connector and set the old fan aside.
3. Position NRF 47305: Align the new fan’s mounting frame with the radiator brackets. Secure it using the supplied bolts, ensuring a snug fit to prevent vibration.
4. Connect Wiring: Attach the fan’s electrical connector to the vehicle’s power and ground terminals. Verify polarity to avoid reverse operation.
5. Test Operation: Reconnect the battery and start the engine. Observe the fan engaging at idle and increasing speed as engine temperature rises.

Performance Benefits

• Consistent Airflow: The 250 W motor drives a large‑diameter blade set, delivering steady airflow even under high ambient temperatures.
• Reduced Engine Heat: By maintaining lower coolant temperatures, the fan helps prevent overheating during prolonged idling or heavy load conditions.
• Longevity: The aluminum housing and reinforced blades resist corrosion and wear, extending service life beyond typical aftermarket fans.
• Quiet Operation: Precision-balanced blades reduce noise levels, contributing to a more comfortable cabin environment.

Maintenance Tips

1. Regular Inspection: Check the fan blades for dents or cracks every 12,000 km. Replace if damage is detected.
2. Electrical Connections: Inspect wiring harnesses for fraying or corrosion. Clean connectors with a contact cleaner to ensure reliable power delivery.
3. Lubrication: The fan motor shaft is sealed; no external lubrication is required. However, keep the surrounding area free of debris that could impede airflow.
4. Cooling System Flush: Perform a coolant flush every 30,000 km to maintain optimal heat transfer between the engine and radiator.
