Attention: Vehicles manufactured from 8/93 and models with a 1.9 liter supercharged diesel engine with G60 and VR6 engines are equipped with a V-ribbed belt instead of a V-belt to drive the alternator, see next chapter.
V-belt for generator drive
4-cylinder petrol engine: Loosen bolts for tensioning bracket -1- and alternator by approx. 1 turn.
Attention: The generator must only be slightly loosened so that it can deflect to the side under the influence of its weight.
Diesel engine: tensioning nut -2- is located under the alternator. Loosen bolts -1- and locking bolt -3- at least 1 turn. Now the generator should be mobile enough.
Turn tensioning nut -2- to the left, this will loosen and remove the V-belt.
Apply V-belt.
Attention: if the V-belt is replaced, an original V-belt of the same size from VW must be installed.
Turn the tension nut to the right to tighten the V-belt. The V-belt will be tensioned correctly if, for a used V-belt, the tension nut is turned to the right by a torque of 4 Nm, and for a new V-belt by a torque of 8 Nm. While holding the nut in this position, tighten the mounting bolts to 35 Nm.
Attention: to tighten the tension nut, a torque wrench with an interchangeable SW 32 ring wrench is required. A conventional HAZET 2593-22 wrench can also be used complete with a torque wrench and a strongly curved SW 13 ring wrench.
Tighten the alternator and tension bracket bolts.
Vehicles with optional equipment such as power steering and air conditioning have additional V-belts to drive the power steering pump and compressor. For the tension of these belts, see chapters «Steering» and «Heating system».
