Fan Rotor
Detroit Diesel

This fan rotor is a fundamental component in the engine cooling system, responsible for generating airflow to dissipate heat from the engine and prevent overheating. Crafted from high-strength steel, it offers durability and resistance to fatigue under continuous operation. With an outer diameter of 125 mm and a width of 26.50 mm, it is designed to fit precisely within the fan assembly, ensuring balanced rotation and maximum airflow efficiency. Properly functioning fan rotors promote optimal operating temperatures, extending engine lifespan and maintaining performance during heavy-duty tasks. The robust construction minimizes vibration and noise, contributing to a quieter, more reliable cooling system. Source One Parts Center recommends this component as a critical element for maintaining effective engine cooling, especially in demanding environments where heat management is vital for engine health.
