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 failure is often a visible coolant leak, typically appearing as puddles under the machine or a persistent sweet smell. If left unaddressed, the leak will worsen, leading to a significant drop in coolant level and potential engine overheating. Continued operation with a compromised cooling system can lead to severe engine damage.

Installation Tip

Ensure the mating surfaces on the engine block and radiator are clean and free of debris before installation. Avoid overtightening the clamps, as this can damage the tube or the sealing surfaces.

Service Note

Inspect hoses and clamps connected to this tube assembly for signs of wear, cracking, or leakage during replacement.
