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 might be a persistent rise in engine coolant temperature, especially under load. This can progress to visible coolant leaks from the tanks or core, or even steam escaping from the engine bay, potentially leading to engine damage from overheating.

Installation Tip

Ensure all mounting brackets and connections are properly aligned before tightening to prevent stress on the radiator core. Always use new seals and O-rings for coolant connections to prevent leaks.

Service Note

Inspect the radiator cap, fan shroud, and coolant hoses for any signs of damage or wear when replacing the radiator.
