Installation & Application Notes

Flush cooling system with distilled water before refilling. Use pre-mixed coolant — never plain water, which causes corrosion. Pressure-test system after any cooling repair. Check thermostat by immersing in hot water — should open at rated temperature.

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 failing spider fan assembly may first present as a wobble or vibration in the fan, accompanied by increased noise. If left unaddressed, the connection between the fan and the hub can weaken, leading to reduced airflow and potential fan blade detachment. This can result in significant engine overheating and damage.

Installation Tip

Ensure the fan hub is clean and free of debris before mounting the new spider assembly. Avoid striking the fan blades directly when tightening the mounting bolts, as this can damage the blades or the assembly.

Service Note

Inspect the fan belt tension and condition, as well as the fan blades for any signs of damage or imbalance, during spider fan assembly replacement.
