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 indication of a failing water pump is often a visible coolant leak from the weep hole, signaling a compromised seal. If ignored, this can lead to a gradual loss of coolant and subsequent engine overheating. Continued operation with a faulty water pump risks severe engine damage due to uncontrolled heat buildup.

Installation Tip

Ensure the engine block's water passages are clean and free of debris before installing the new water pump. Do not reuse the old gasket; always use a new one or sealant as specified.

Service Note

Inspect the drive belt for the water pump, the thermostat, and radiator hoses for any signs of wear or damage during replacement.
