What are the causes of car water pump failure?
1 Answers
Car water pump failure causes: 1. Coolant leakage caused by aging water pump seals; 2. Over-tightened engine serpentine belt leading to premature wear; 3. Exceeding service life without replacement; 4. Bent pump shaft, worn shaft neck, or damaged threaded end; 5. Broken impeller blades or worn shaft bore; 6. Wear degree of water seals and bakelite washers; 7. Poor pump performance causing circulation issues that generate high temperatures, leading to leaks or broken blades; 8. Long-term antifreeze neglect causing internal corrosion that ultimately damages the pump.
