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 fan assembly may initially present as a slight increase in engine coolant temperature, especially under load. If ignored, the fan's reduced airflow will lead to progressively higher operating temperatures, potentially causing overheating warnings. Continued operation with a compromised fan assembly risks severe engine damage due to sustained high temperatures.

Installation Tip

Ensure the fan blades are correctly oriented to pull air through the radiator, not push it away. Avoid overtightening the mounting bolts, as this can strip the threads or warp the fan hub.

Service Note

Inspect the radiator for bent fins and the fan shroud for damage or obstructions when replacing the fan assembly.
