• Fluid‑Friction Coupling Design: Provides smooth, continuous fan speed adjustment without the need for electronic controls.
• Wide Operating Range: Handles low‑speed idle cooling and high‑load highway conditions with equal efficiency.
• Durable Construction: Made from high‑strength alloy and reinforced with a heat‑resistant gasket to withstand prolonged thermal cycling.
• Easy Installation: Fits the original mounting points on the G‑Class T1 chassis, requiring no modifications.
• OEM Compatibility: Matches the specifications of the original factory part, ensuring seamless integration.

Technical Specifications

Installation Guide

Installing the NRF 49533 is straightforward for technicians familiar with the G‑Class T1 cooling system:

1. Disconnect the battery to prevent accidental electrical contact.
2. Remove the existing fan clutch by loosening the mounting bolts and sliding it out of the fan housing.
3. Align the new NRF 49533 with the mounting flange, ensuring the gasket sits evenly.
4. Tighten bolts to the manufacturer’s torque specification (typically 30 Nm).
5. Reconnect the battery and perform a quick test run to verify fan operation.

Performance Benefits

• Consistent Cooling: Maintains engine temperature within the optimal range, reducing wear and improving fuel efficiency.
• Reduced Noise: The viscous coupling dampens fan vibration, resulting in a quieter cabin environment.
