Car water pump failure causes: 1. Aging of the water pump seal ring; 2. Over-tightened engine serpentine belt; 3. Long-term neglect of coolant replacement; 4. The water pump has reached its service life. Symptoms of car water pump failure: 1. Elevated engine coolant temperature that does not decrease; 2. Coolant leakage near the water pump area of the engine; 3. Abnormal noises from the water pump area after starting; 4. Unstable engine idle speed. Automotive engines widely use centrifugal water pumps, whose basic structure consists of the pump housing, connecting flange or pulley, pump shaft and bearings or integrated shaft bearings, pump impeller, and water seal components.
