Engines Powertrain
Accessory Drive Belts
• A V-ribbed drive belt is fitted to drive the engine accessories. There are two variants of
the accessory belt drive:
– Vehicles without A/C have one drive belt
– Vehicles with A/C have two drive belts
• Both variants have elastic drive belts (also termed as stretchy belt), i.e. they do not need
a tensioner. Since retensioning is not possible, the drive belt must not be re-used.
