How to assemble the bearing of the automobile water pump shaft!

When it comes to the replacement of auto parts, many small partners only know that similar filter elements are more common. And the car water pump shaft bearing we talked about today needs to be replaced when necessary, otherwise it will affect the reciprocating circulation of the coolant. In the end, the car water pump can generally be used for several years, how to judge the car water pump is broken.

There is no specific time limit for the service life of automobile water pump shaft bearings. If they are used improperly, they may be directly scrapped after a few years. So if it is well maintained in normal times, it will not be a problem to use it for more than ten years. At that time, you may not consider replacing the car's water pump, but directly replace it with a new car. But it should be noted that if the following phenomena occur, it is likely that the car water pump is damaged and needs to be inspected and repaired in time.

The phenomenon of damage to the bearing of the automobile water pump shaft:

Unsteady idling

First of all, we have to know that the water pump is connected with the belt to pump cold water out of the water tank to cool the engine. However, if the car water pump is damaged, it will definitely affect its rotation resistance. Then after the car is started, the engine speed will be unstable. When the resistance is very high (mostly in winter), the flameout is likely to occur.

Leaking water pump

The most common phenomenon is the leakage of coolant. At this time, we will find some water marks in the vents of the water pump. We must know that the coolant itself is to prevent the problem of "boiling the pot" when the engine is running at high speed. If the coolant leaks, there will naturally be a big problem. At this time, you need to check whether the cooling fan, radiator, and water pump are damaged, if any, you need to deal with it in time.

Noise problem

If we hear some abnormal noises like "chucking" (rotating friction sound), it is to remind us that the car's water pump shaft bearing has begun to be damaged. Of course, it may also be because the internal bearing is damaged or the impeller is loose or detached, which causes abnormal noise. Therefore, when there is a noise problem, you need to investigate these factors one by one, but it is really difficult to solve it by yourself, so we'd better leave it to professionals.
