There are many cracks in the support of Petrol Car water pumps and bearings, which is mainly caused by too frequent vibration and too large vibration amplitude. For example, if there are parts in the water pump that are bent, vibration will occur. If the vibration is too severe and frequent, a large number of cracks will appear in the water pump and bearing support. In addition, excessive engine load can easily cause damage to the water pump.
Since the Petrol Car water pump is connected to the belt to extract cold water from the water tank, if the rotation resistance of the water pump is affected, it will directly affect the engine speed, and the vehicle speed will be unstable, which is mainly manifested in the Petrol Car's speed jumping and unstable after starting. If the resistance is very large, it may also stall. This situation often occurs in winter.
Petrol Car parts manufacturers introduced that the most common fault of most Chery Car water pumps is leakage. The main reason for leakage is that the seal is not done very well, so that the coolant penetrates into the bearing of the water pump, thereby flushing the lubricant on the bearing, causing bearing damage. Such leakage is an internal leakage. External leakage is also the main cause of water pump damage, including aging of engine seals and gaskets due to long-term use, internal leakage of the heater, and leakage of the oil cooler.
If there is obvious noise in the Chery Car water pump, it means that the inside of the water pump has begun to damage. The main reason for the noise phenomenon is that the bearing begins to damage or the impeller begins to loosen during rotation and gradually separates from the shaft, resulting in noise.
It is mainly caused by improper installation. When installing the Petrol Car water pump, if it is not operated according to the specified method or is not installed in place, the bearing will not play the corresponding role, and the impeller will be more susceptible to damage. Another reason is that the impeller is corroded by antifreeze in the water pump, but with the gradual improvement of modern antifreeze production technology, such a situation is not common, but if it is not regularly inspected and well maintained, the impeller is still very easy to damage.
