Introduction

The Cummins 2874119 Fan Hub is a critical component in the cooling systems of heavy-duty trucks. It ensures optimal engine temperatures by facilitating efficient airflow through the radiator. This part is essential for maintaining engine performance and longevity under various driving conditions ¹.

Basic Concepts of a Fan Hub

A fan hub is a mechanical device that connects the engine-driven fan to the radiator. Its primary function is to control the fan’s operation based on the engine’s temperature. When the engine temperature rises, the fan hub engages the fan to increase airflow through the radiator, thereby cooling the engine. Conversely, when the engine is cool, the fan hub disengages the fan to reduce drag and improve fuel efficiency ².
