Hi,

My 940 Turbo 2.0L, has 270000Km.
During the last three years, I am experiencing extreme and fast wearing of the the alternator belt, all genuine Volvo belts.
The current belt has only 9000 Km and will break soon.

Please see some pictures I just took:

Typically they lasted about 60000 Km
The belt before my current one, it lasted 20000 Km
The one I currently have is on its way to break, after 9000 Km

When I saw the present belt deteriorate, I changed the alternator rubber bushing, but I am afraid the belt was already compromised.
I guess that in order to know if the rubber bushings were the problem, I need to put on a new belt.

In general, I did not have any issues, in 2016 I changed all the belts in one go, timing belt, AC, alternator, and power steering.
It may be a coincidence, but since then, the alternator ones do not last.

The pulleys seem perfectly aligned, but this is to the naked eye.

What is the best way to make sure the pulleys are perfectly aligned?

Any further advice is welcome.

Thank you,
Alex
