When the battery starts to “moan” at the first frost, or the engine no longer wants to start at all, the driver goes for a new battery. However, this often does not solve the problem. In addition, whistling noises begin to come from under the hood when the engine is running. The AvtoVzglyad portal tells about the causes of breakdowns and their consequences.
You should pay attention to the generator and pulley when the car’s odometer is over 80,000 km. It is after this run that problems can arise. For example, after starting the engine, whistling noises can be heard under the hood. This indicates that the lubrication of the assembly has developed.
It is necessary to inspect the overrunning clutch of the generator. It would seem that it resembles an ordinary roller, but in fact a consumable is a complex device. Inside there are several bearings with which the entire belt drive of auxiliary units is synchronized. This solution reduces the jerky loads on the generator while extending the life of the drive belt. But if the bearings and the inner ring of the assembly wear out a lot, they can seize up. In this case, the design turns into an ordinary roller, which causes a problem: the speed of the drive belt and the rotational speed of the generator begin to strongly disagree.
As a result, strong loads act on the generator, reducing its resource. And the same loads go to the “drive”. As a result, it may weaken, which will inevitably affect the battery’s condition. The battery charge drops and the engine does not start at the first cold weather.
In the worst case, the belt breaks. This can lead to the fragments already hitting the timing belt, which threatens to deform or come loose. The result is an engine overhaul.
Finally, carefully inspect the tensioners. If it is clear that at least one of them is skewed, and the working surface is all in “shells”, then such a spare part will not work well. And it will “kill” any new belt. This item needs to be changed urgently.
