Electronic water pump is an important part of the engine cooling system, its damage may be caused by a variety of factors, the damage of the pump seal ring and bearing is one of the common reasons. When the water pump fails, it must be checked and replaced in time to prevent the water temperature of the engine from being too high during the working process, resulting in engine boiling, which affects the heat dissipation effect of the engine.
Engine water pump broken performance: Engine parts will have noise, idle instability, water pump leakage, coolant leakage, cooling system failure, water temperature is too high, engine water temperature is unstable, pump impeller cracking, cooling cycle ability weakened or even no cycle, idle jitter, hot air is not hot, water pump shaft wear and bend, rapid instability, please check whether the water pump is damaged. And timely replacement to ensure driving safety.
