Technical Specifications

Installation Overview

The NRF 47217 fan is designed for straightforward installation on most automotive radiator assemblies. Follow these steps to ensure optimal performance:

1. Disconnect the Battery: Always isolate the electrical system before working on cooling components.
2. Remove Existing Fan: Unscrew the mounting bolts, detach the fan from the radiator housing, and disconnect any wiring harnesses.
3. Prepare New Fan: Verify that the O‑ring gasket is intact. If damaged, replace it with a new one to maintain water‑tight integrity.
4. Mount the Fan: Align the fan flange with the radiator mounting holes and secure using the supplied bolts. Tighten evenly to avoid warping.
5. Reconnect Wiring: Attach the fan’s electrical connector, ensuring a firm connection. Use a multimeter to confirm correct polarity.
6. Test Operation: Reconnect the battery, start the engine, and observe fan activation during coolant temperature rise. Check for any abnormal vibrations or noises.

Maintenance Tips

• Regular Inspection: Periodically check the fan blades for dents or debris that could impair airflow.
• Clean Gaskets: Remove accumulated grime from the O‑ring area to preserve a proper seal and prevent coolant leaks.
• Electrical Check: Inspect wiring harnesses for fraying or corrosion; replace any compromised sections promptly.
• Lubrication: If the fan housing includes bearing seals, apply a light lubricant as per manufacturer recommendations to reduce wear.
