Function
Driving of the alternator (G2) and coolant pump is by means of a poly-V belt which is tensioned by a spring-loaded tensioning device. Transfer of the spring force on the V-belt takes place via the tensioner pulley mounted on the clamping device.
For vehicles with code (I01) Air conditioning Plus the drive for the refrigerant compressor is by means of a stretch belt.
