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

Initial signs of failure may include a slight increase in engine operating temperature or reduced heating performance in the cab. If ignored, the component can lead to sustained high temperatures, potentially causing engine damage. Continued operation with a compromised cooling system risks severe engine overheating and costly repairs.

Installation Tip

Ensure the cooling system is completely drained before removal to prevent coolant spillage. Do not overtighten mounting bolts, as this can distort the component or its mounting surface.

Service Note

Inspect all coolant hoses and the radiator for leaks or blockages when replacing this component.
