Failure Symptoms

The first sign of a failing fan hub is often an audible noise, such as grinding or rattling, coming from the front of the engine. If left unaddressed, the fan may begin to wobble excessively or stop spinning altogether, leading to rapid engine overheating. Prolonged overheating can cause severe damage to the engine block, cylinder head, and other critical components.

Installation Tip

Before removing the old hub, mark the orientation of the fan pulley relative to the hub to aid in reassembly. Ensure the mounting bolts are torqued to the manufacturer's specifications to prevent loosening.

Service Note

Inspect the cooling fan blades for damage and the drive belt for wear and proper tension when replacing the fan hub.
