V-ribbed alternator belt

As a generator drive, Opel uses a flat belt, reinforced on the working side, turned to the belt pulleys, with numerous ribs. The so-called V-ribbed belt rotates on drive pulleys, which are provided with a profile suitable for this. A special tensioning device constantly maintains the correct tension of the polypin belt. This is carried out by a tensioning element, which, by means of a spiral spring, presses the tensioning roller against the reverse side of the polypin belt.

In fact, this reliable frame should have served throughout the life of the engine. However, the belt may fail. If the V-ribbed belt breaks, you are good to go! Because the water pump is driven by a toothed belt. Although the power steering pump or air conditioner compressor is not working.
