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

A worn fan hub may exhibit play in the bearings, leading to increased noise and vibration from the front of the engine. If left unaddressed, the bearing failure can cause the fan to seize or detach, leading to a rapid loss of engine cooling and potential overheating. This can result in significant engine damage and costly repairs.

Installation Tip

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

Service Note

Inspect the cooling fan blades for damage and check the condition and tension of the drive belt.
