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

The first sign of a failing radiator is often a gradual increase in engine operating temperature, especially under load. If left unaddressed, leaks can worsen, leading to significant coolant loss and severe engine overheating, which can cause catastrophic internal damage. Continued operation risks major mechanical failure and extended equipment downtime.

Installation Tip

Ensure the engine is completely cool and the cooling system is properly drained before attempting removal to avoid burns and coolant spills. When installing, ensure all mounting points are aligned correctly to prevent stress on the radiator core.

Service Note

When replacing the radiator, it is crucial to inspect and clean the cooling fan, shroud, and all coolant hoses for any signs of wear or damage.
