NRF 47031 Radiator Fan

The NRF 47031 is a high‑performance radiator fan designed specifically for the cooling systems of Chrysler and Dodge vehicles, including the Grand Voyager, Caravan, and various van models. This fan delivers reliable airflow to maintain optimal engine temperatures under demanding operating conditions.

Key Features

• Diameter: 328 mm (12.9 in) – the ideal size for most Chrysler/Dodge radiators.
• Dual‑stage motor: Provides efficient power delivery while keeping noise levels low.
• High airflow capacity: Ensures rapid heat dissipation even during heavy load or high ambient temperatures.
• Durable construction: Made from corrosion‑resistant materials to withstand the harsh automotive environment.
• Easy installation: Fits standard mounting brackets used on Chrysler and Dodge models from the mid‑1990s through early 2000s.

Vehicle Compatibility

The NRF 47031 fan is engineered for a wide range of Chrysler and Dodge vehicles, including but not limited to:

• Chrysler Grand Voyager (various trim levels)
• Dodge Caravan (including the III MPV and later models)
• Chrysler Voyager/Grand GS, RG, RS variants
• Models equipped with 3.8 L engines from 1995‑2001
• Other Chrysler/Dodge vans that use a 328 mm radiator fan assembly

Because the fan is manufactured to match OEM specifications, it integrates seamlessly with existing cooling system components such as the condenser, heater core, and coolant hoses.

Installation Overview

1. Remove the old fan: Disconnect the electrical connector, unscrew the mounting bolts, and carefully lift the fan out of the radiator housing.
2. Prepare the new NRF 47031: Verify that the fan is free from packaging damage. If necessary, clean the fan blades with a soft brush to remove debris.
3. Mount the fan: Align the mounting holes with the radiator bracket and secure with bolts. Tighten to the manufacturer’s torque specification.
4. Reconnect electrical wiring: Attach the connector, ensuring proper polarity and a snug fit.
5. Test operation: Start the engine and observe fan activation at idle and under load. Check for any unusual vibrations or noises.

Performance Benefits

Installing the NRF 47031 fan offers several tangible advantages:

• Consistent cooling: Maintains engine temperature within safe limits, reducing the risk of overheating during long drives or heavy towing.
• Improved fuel efficiency: A well‑cooled engine operates more efficiently, potentially lowering fuel consumption.
• Extended component life: By preventing excessive heat buildup, critical parts such as the head gasket and cylinder heads experience less thermal stress.
• Reduced noise: The dual‑stage motor design minimizes whine compared to older single‑speed fans.

Maintenance Tips

To keep the NRF 47031 fan running smoothly, perform routine checks:

• Inspect the fan blades for dents or warping every 12,000 mi (or annually).
• Clean the fan housing and surrounding area to prevent dust accumulation.
• Verify electrical connections for corrosion or loose contacts.
• Replace any worn belts or pulleys that drive the fan motor.
