Wear and Tear: Over time, the seals and bearings in the pump can wear down, causing leaks o r mechanical failure.
Coolant Contamination: If coolant is not replaced regularly o r is of poor quality, contaminants can damage the water pump and other cooling system components.
Electrical Issues: For the inverter pump, electrical faults e.g., wiring issues o r failed pump motors can cause it to malfunction.
