Even auto water pump shaft bearing assembly way!

Said to the auto parts replacement, a lot of friend only know similar to filter the more common. And today we're talking about auto water pump shaft bearing, also need to replace when necessary, otherwise it will affect the cooling fluid of the reciprocating cycle. How on earth was that auto pumps usually can use a few years, auto water pump is broken. Auto water pump shaft bearing the use fixed number of year, and don't have a specific time, inappropriate use of words may directly discarded after a few years. If at ordinary times maintain well, with more than ten years is not a problem, then you might not consider replacement auto water pump, but directly in a new car. But notice that if appear the following phenomenon is, probably because auto water pump damaged, need to check the maintenance in a timely manner. Auto water pump shaft bearing damage phenomenon: idle instability, first we need to know the pump is connected with the belt to the cold water pumped from the tank to the engine cooling. However, if the pump case of damage to the car, is certainly affect its rotational resistance. Then, after the car starts the engine speed beating instability occurs. In the very great resistance ( In winter) , it is likely that would be a stall. Is one of the most common phenomenon coolant pump leak leakage, we can find some water mark on the pump shaft. To know the cooling fluid is itself in order to prevent the engine operate at a high speed, 'boiled' problems. If cooling fluid leakage, nature is there is a big problem. This time will need to check the cooling fan, radiator and water pump whether there is any damage, if any need timely treatment. The noise if we heard some similar 'ChengChengCheng' sound ( Rotating friction sound) , is a reminder that, auto water pump shaft bearing has been damaged. Of course, it may also be because the internal bearing damage or loose impeller in or out of, resulting in sound. So, at the time of the noise problem, trying to identify these factors one by one will be needed, but depend on oneself to solve indeed is a little difficult, so we'd better to professionals.
