Removing
6. Follow the steps in steps 1 and 2 if you have not already done so.
7. Disconnect the wire «masses» from battery (see «Disconnecting the battery»).
8. Loosen the top and bottom nuts/bolts (whichever is applicable) generator mounting and adjusting plate mounting bolt.
9. If necessary, turn the adjusting bolt to relieve tension on the drive belt, and then remove the belt from the pulleys (pic. 12.9).

Note. If the belt is to be reused, mark the direction of rotation on the belt before removing it. This will ensure that the belt is installed correctly.
Installation
10. When replacing a belt, make sure that the new belt is of the correct type, and if a removed belt is being installed, follow the marks made during removal to install it correctly. Slide the belt over the pulleys and use the adjusting bolt to take up the slack in the belt.
11. Tension the drive belt as described in the following paragraphs.
Stretching
Advice. Proper tension of the drive belt ensures its reliable operation throughout its entire service life, and sagging, slippage and squealing. Beware of exceeding the required tension, as this may contribute to increased wear on the generator bearings.
12. Follow the steps in steps 1 and 2 if you have not already done so.
13. The belt should be tensioned so that there is approximately 5.0 mm deflection in the middle of the longest section between the pulleys when applying strong thumb pressure (see note at the beginning of this paragraph).
14. To make the adjustment, turn the adjusting bolt just enough to give the correct tension. This should be done in a position where the mounting bolts are holding the alternator, but still allowing for a slight amount of movement.
15. Turn the crankshaft two turns, check the tension again, and then tighten both bolts / nuts securing the generator. If applicable, also tighten the adjustment bar bolt to the appropriate support bracket.
16. Connect the wire «masses» to the battery.
17. Fix the coolant hoses in their original position (where necessary) and install the wheel arch locker. Install the wheel and lower the car.
