Alternator belts should be changed every 36,000 miles (60,000km) for proper maintenance.
We recommend you look at your old belt prior to ordering. In some cases, this belt applies to the later dual spark models. You may be able to confirm the correct belt if the BMW # 12 31 1 341 779 is still legible.
The Continental Ref # 4PK611 should also be visible.
