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.
