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

Observable signs of failure include a persistent coolant leak originating from the component or a consistent rise in engine temperature during operation. If ignored, the engine may begin to lose power, and prolonged overheating can cause severe internal damage.

Installation Tip

Ensure the engine is completely cool before starting removal to avoid burns from hot coolant. Never force the component into place; if it doesn't fit easily, recheck alignment and ensure no obstructions are present.

Service Note

During replacement, it is advisable to inspect the radiator, hoses, and water pump for any signs of deterioration or blockage.
