Abnormal sound of automobile engine water pump

The symptoms of abnormal sound of water pump are as follows: Noise of the engine part: This sound is a friction sound of rotation, similar to the sound of "miso miso".This kind of sound can accelerate with the rotation of the engine and change the volume.

Abnormal sound of the water pump generally refers to the wear, loosening or lack of oil of the pump shaft bearing, the failure or installation of the pump shaft retaining ring, the movement of the bearing, the collision of the back of the impeller and the pump cover, and the resulting shaking of the pulley and fan impeller. When the engine is running, put the stethoscope on the water pump shell and change the engine speed at the same time.

The abnormal sound of the water pump needs to be replaced. First of all, the bearing gap in the water pump is large, or the bearing is worn out. If the abnormal sound is not replaced, the water pump may die if it is serious, then the cost of loss will be large. If there is a problem, it must be repaired as soon as possible. Don't leave a small problem as a big problem, so delay Mistakes also cost a lot of money.

The abnormal sound of the water pump is the sound made by the loosening of the rotor part in the shaft.This kind of sound is often periodic. For example, when the impeller and shaft sleeve of the circulating water pump are loose on the shaft, it will make a clicking impact sound.

What's wrong with the abnormal sound of Xuanyi water pump bearing

There are three main reasons for the abnormal sound of Xuanyi water pump: loose wear of the pump bearing, lack of lubricating oil in the pump, and incorrect installation of the shaft retaining of the pump. Centrifugal water pump is one of the main parts of automobiles, which is mainly composed of water pump housing, connecting plate or pulley, water pump shaft, bearing or sliding bearing, water pump impeller and water seal, etc.

The abnormal sound of Xuanyi water pump is generally caused by the wear, looseness or lack of oil of the pump shaft bearing, the pump shaft ring is not installed or not installed, the bearing is moving, the back of the impeller rubs against the pump cover, and the resulting shaking sound of the pulley and fan impeller.Just replace the water pump or add lubricating oil.

Xinxuanyi water pump squeaks Xuanyi engine abnormal sound Xuanyi water pump abnormal noise The reason is: pump bearing wear and loose; water pump lacks oil; water pump shaft stop ring is not installed.

The abnormal sound of Xuanyi water pump bearing can be detected in advance: remove the belt and turn it on again to listen to whether there is any abnormal sound. After the belt is removed, the pump does not work. If the abnormal sound is still there, it means that the pump bearing is not broken, and on the contrary, the pump bearing is damaged. To use this method, the engine must be turned off within 1 minute, otherwise the engine will be damaged.

The abnormal sound of the water pump may be caused by foreign matter or bearing wear inside. The symptoms of Xuanyi water pump failure are: the pump is damaged, the cooling circulation capacity is weakened or even not circulated, and the phenomenon of "coolant boiling" occurs; water leakage near the engine pump.

What is the reason for the abnormal sound of the car pump

1. The abnormal sound of the car's water pump may be caused by foreign matter inside the pump, or the wear of the car's bearing. If the car's pump is broken, it will also be accompanied by the water pump. There is water leakage and the cooling cycle capacity of the car is weakened.

2. [Pacific Automobile Network] The reason for the abnormal sound of Junwei water pump: the water pump bearing is damaged; the fan blade of the water pump falls off, the high-flow water flow drives the falling off blades to impact; the pump temperature is too high. It will cause poor heat dissipation in the water tank, and it is easy to cause the water tank to boil.

3. The reason why the car water pump is broken is: coolant leakage, water pump sealing ring aging; the engine combination belt is too tight, which will also cause premature wear of the water pump;If the antifreeze is not replaced for a long time, internal corrosion will cause damage to the water pump; the water pump will not be replaced for a long time when it reaches its service life.

4. There is an abnormal sound in the water pump when the engine is working. The abnormal sound of the water pump may be caused by foreign objects inside or bearing wear. The reason for the damage of the car water pump: unstable idle speed: the failure of the pump can increase the rotational resistance of the pump. Because the pump is connected to the timing belt, the increase in the rotation resistance of the pump can directly affect the rotation of the engine.

How to deal with abnormal noise of engine pump

1. Noise of the engine part: This sound is the friction sound of rotation, similar to The sound of "miso miso". This kind of sound can accelerate with the rotation of the engine and change the volume. This kind of noise generally becomes more and more obvious with the severity of the failure; there is a strange sound in the pump when the engine is working.

2. If the engine is found to be abnormal when the car is driving, it should be stopped immediately for diagnosis and elimination. If you can't be sure by yourself, you can go to the nearby repair shop for professional investigation and maintenance according to the situation. The car engine is composed of multiple components. Pump noise: Pump noise is mainly caused by the pump wheel bearing of the pump.

3. At the upper outlet of the engine, a water pump is installed, driven by a fan belt, to drain the hot water from the engine cylinder waterway and the cold water is pumped in. There is also a thermostat next to the water pump. When the car is first started (cold), it is not turned on, so that the cooling water does not pass through the water tank and only circulates in the engine, commonly known as a small cycle.

4. The abnormal sound of Xuanyi water pump bearing can be detected in advance: remove the belt and then turn on the fire to listen to whether there is any abnormal sound. After the belt is removed, the pump does not work. If the abnormal sound is still there, it means that the pump bearing is not broken, and on the contrary, the pump bearing is damaged. To use this method, the engine must be turned off within 1 minute, otherwise the engine will be damaged.

5. When the car finds that there is an abnormal sound in the engine during driving, it should immediately stop for diagnosis and exclusion. If it cannot be determined by yourself, you can go to a nearby garage for professional inspection and maintenance depending on the situation.

Does the abnormal noise of the engine pump have a great impact on the engine

In the case of affecting the abnormal noise of the pump, the abnormal noise produced by the engine pump during rapid acceleration is the loosening of the connecting rod bearing and the melting of the bearing. Or inconsistent rotation of size, looseness of crankshaft bearing or burning of bearing, fracture of piston pin, fracture of crankshaft, centrifugal water pumps are widely used in automobile engines.

If there is an abnormal sound in the car water pump, it means that there is a fault. It is recommended to deal with it as soon as possible. If it is not treated, there may be no problem at that time. But when the water pump does not work properly, it may cause the high temperature of the engine and cause damage to the engine.

If the water pump breaks down, it will directly affect the idle speed, resulting in unstable speed. After the vehicle starts, the speed jumps. If the resistance is too great, it will cause the engine to shut down.Leakage is a common fault, which will lead to a lack of coolant after leakage, which will cause symptoms of high water temperature in the car and seriously affect the wear of the bearing.

It usually occurs for a period of time when the engine is started. If the power is too great, it will turn off; coolant leakage; noise problem: when the car water pump shows signs of starting to be damaged, it will show abnormal sound symptoms. The reason for the noise is that the internal bearing is damaged or the impeller is loose and detached from the hinge. Strange sound.

What is the reason for the abnormal sound of Xuanyi water pump?

1. The reasons for the abnormal sound of Xuanyi water pump are: the bearing of the pump is loose and worn; the pump lacks oil; and the pump shaft blocking ring is not installed well.

2. The reason for the abnormal sound of Xuanyi water pump is the wear and loosening of the pump bearing or lack of oil;The reason for the abnormal sound of Xuanyi water pump due to the failure of the pump shaft retaining ring is caused by loose wear of the pump bearings, lack of oil or improper installation of the shaft retaining ring.

3. The abnormal sound of Xuanyi water pump is generally due to the wear, looseness or lack of oil in the shaft bearing of the pump, the shaft of the water pump is not installed or not installed, the bearing is moving, the back of the impeller rubs against the water pump cover, and the resulting shaking of the pulley and the fan impeller.

4. The abnormal sound of the water pump may be caused by foreign matter or bearing wear inside. The symptoms of Xuanyi water pump failure are: the pump is damaged, the cooling circulation capacity is weakened or even not circulated, and the phenomenon of "coolant boiling" occurs; water leakage near the engine pump.

5. It usually appears after the engine starts for a period of time. If the power is too high, it will turn off; coolant leakage; noise problems:When the car water pump shows signs of starting to be damaged, it will show abnormal noise symptoms. The reason for the noise is that the internal bearing is damaged or the impeller is loose and the hinge is detached from the hinge to produce abnormal noise.
