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

An initial symptom of a failing fan blade might be increased noise from the engine compartment, such as rattling or excessive whistling. If the blade becomes unbalanced or damaged, vibrations can be felt throughout the machine, and cooling efficiency will decrease, leading to higher engine temperatures. Continued operation with a compromised fan blade risks overheating the engine, potentially causing severe internal damage.

Installation Tip

Ensure the fan mounting bolts are torqued evenly in a star pattern to prevent warping the fan hub or blade. Double-check that the blade is oriented correctly for counter-clockwise rotation before final tightening.

Service Note

Inspect the fan drive belt and tensioner for wear and proper function when replacing the fan blade.
