Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of a failing fan hub include noticeable vibration of the cooling fan or unusual noises, such as grinding or rattling, emanating from the front of the engine. If the hub becomes severely worn or loose, it can lead to the fan wobbling excessively or even detaching, compromising engine cooling. Continued operation risks overheating and potential damage to surrounding components.

Installation Tip

Ensure the mounting surface on the water pump or fan drive is clean and free of debris before installing the new hub. Do not overtighten the mounting bolts, as this can strip the threads or damage the hub.

Service Note

Inspect the cooling fan blades for damage, cracks, or warping, and check the fan drive belt tension and condition when replacing the fan hub.
