Diagnostics and replacement of the belt of auxiliary units

The drive belt, after a successful paid tensioning procedure at the dealer, sometimes still whistled. On a cold, under load, not for long, but whistled.
One friend advised him to change, because "There is sand in the streams and it is polished over time."

He turned out to be right

The belt is dry and there are cracks on it

I repeat once again - the belt for 1.6 rollers is tensioned (manually, NOT self-tensioning).
For convenience, I completely unscrewed the front of the fender liner. You can do everything from under the hood, but then pulling the belt is not very convenient. Yes, and the roller is easier to loosen from the bottom.

The belt was hung by Contitech 7PK1153, the price is 334 rubles.
I tested it cold this morning. Everything is quiet. The inclusion of energy-intensive devices is not accompanied by the sounds of incredible attempts from under the hood.
