A broken car water pump usually manifests itself in three ways: idling problems, leaking problems, and noise problems.
Damage to the water pump directly affects the idle speed, making the vehicle speed unstable. The speed will increase after the vehicle starts. If the resistance is too great, the motor will stall. . Leaking is a common fault. Due to the leak, symptoms such as high water temperature due to lack of coolant will seriously affect bearing wear. Noise is a sign that the water pump is starting to fail, so you need to pay more attention to it.
1. The idle speed is unstable. The car's water pump is connected to the belt to draw cold water from the water tank to cool the engine. If there is a problem with the rotation of the water pump, it will directly affect the RPMof the engine. The phenomenon is unstable vehicle speed, which is usually the case. occurs after starting the engine for a while. If the boost is too high, it will stall. From these phenomena, we can first judge that the water pump is damaged.
2. Coolant leaks. This is a common fault. The engine is prone to water leaks near the water pump. At this time, the coolant will leave water marks on the water pump vents. An engine lacking coolant will have a “high fever,” worsening wear. , and in severe cases, smoke or even fire, at that time you should first check whether the important parts of the cooling system (cooling fan, radiator, water pump, etc.) are damaged and do not drive reluctantly.
3. Noise problem. When the car's water pump starts to mountIf there are signs of damage, it will have abnormal noise symptoms, and the cause of the noise is probably because the internal bearings are damaged or the impeller is loose or separated from the rotating shaft, causing abnormal noise. . At this time, you should drive carefully and repair the corresponding parts in time, otherwise the water pump will be blocked and the car engine will not be completely cooled, causing the above situation.
