The fan hub is the central mounting point that connects the engine-driven fan to the front of the engine, transferring rotational force from the crankshaft pulley to spin the cooling fan at the correct speed. It supports the fan blade assembly and, in many configurations, houses or interfaces with a bearing assembly that allows smooth, low-friction rotation. When the fan hub wears, cracks, or its bearing surface deteriorates, fan wobble or complete detachment can follow — reducing airflow, causing rapid engine overheating, and potentially damaging surrounding components including the radiator and fan shroud.
