Is it worth it to engage in such repairs that are associated with the generator belt? Of course, it is worth it if you are not afraid to get your hands dirty and want to understand the principle of the device itself. Replacing the alternator belt is a fairly simple thing that even those who have never been involved in car repair can handle it.
The most accurate and true indicator for repair is when the
alternator belt whistles
. This sound usually begins to appear when a lot of energy is supplied to the car, that is, you turn on the headlights or the radio. Many machines have special sensors that indicate a malfunction.
Before starting work, stop supplying energy. To do this, disconnect the negative charge wire from the battery. Do not forget to turn off the car beforehand. Now we begin a thorough visual inspection of the alternator belt. It is necessary to identify whether there are cracks or tears on it, and also check its elasticity. It often happens that the problem is not in the wear of the belt, but in its tension - it may be too loose.
After you are convinced that the replacement of the alternator belt is necessary, you should purchase the same belt in the store. In order to remove the old, it needs to be loosened. On different brands of cars, that process occurs in different ways and with different details. This can be either a tension bolt or a rail represented by a semicircle. Usually, all work is done using special keys. After the tension is loosened, clearly review the location of the belt. In order not to get confused, you can draw yourself a consistent circuit.
On vehicles with tension bolts, select the key you need to loosen the belt. Then use it to twist the bolt in one direction or the other. No need to twist it completely. Having chosen the desired direction of rotation, scroll the bolt until the belt begins to dangle and you can easily remove it.
After removal has been completed and the alternator belt has been nearly replaced, make sure the new and old belts are the same. If everything fits together, then you can proceed with the installation of a new belt. The most important thing is to observe a clear sequence, otherwise it can lead to damage to the car. Belt replacement ends with a bolt tension. Turn it in the opposite direction. Typically, the optimum tension is indicated in the machine manual. Nevertheless, it is worth remembering that the belt should not be too tight, because it can simply break.
After replacing the alternator belt, it is necessary to check whether everything is done correctly. To do this, connect the power to the battery by inserting a negative wire on the terminal. Next, turn on the ignition. Then we start and turn on almost all the devices that are in the car. We give the car gas. You can pogazat longer. If after that a whistle appears again, this means insufficient tension. Repeat the tightening procedure and check the car again in the same way.
