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

An initial sign of a failing fan spider assembly is audible rattling or wobbling noise from the fan area. If left unaddressed, this can lead to uneven fan rotation and reduced cooling efficiency, potentially causing the engine to overheat. Continued operation with a compromised assembly risks damage to the fan blades, shroud, and cooling system components.

Installation Tip

Ensure the fan clutch (if applicable) is properly serviced and functioning before installation. Avoid overtightening the mounting bolts, as this can strip the threads or warp the assembly.

Service Note

Inspect the fan belt tension and condition, as well as the water pump and radiator for leaks or blockages, when replacing the fan spider.
