Removal
18. Follow the steps described in paragraph. points 1 and 2, if you haven't done so yet.
19. Disconnect the ground cable from the battery (refer to paragraph "Disconnecting the battery").
20. Loosen the two bolts securing the tension pulley assembly to the engine (figure 12.20).
Figure 12.20. Loosen the two tension roller mounting screws (marked with arrows)...
21. Turn the adjusting bolt to move the tensioner pulley away from the drive belt and provide enough slack in the belt to remove the belt, then remove the belt from the pulleys (figure 12.21).

Note: If the belt is to be reused, mark the direction of rotation on it before removing it. This will ensure that the belt is installed correctly.
Installation
22. When replacing a belt, ensure that the new belt is the correct type, and if installing a removed belt, follow the marks made during removal to ensure it is installed correctly. Place the belt on the pulleys so that the belt ribs fit correctly into the grooves on the pulleys and the belt is routed properly.
23. Select the belt slack using the tension pulley adjusting bolt. Then tighten the belt as described below.
Stretching
24. Follow the steps described in paragraph. points 1 and 2, if you haven't done so yet.
25. Correct tension of the drive belt ensures its long service life.
26. The belt should be tensioned so that when pressing firmly with the thumb in the middle of the longest section between the pulleys there is a deflection of approximately 5.0 mm (see the note at the beginning of this paragraph).
27. To make the adjustment, loosen the two tension pulley assembly mounting screws and turn the adjusting bolt until the correct tension is achieved. After ensuring the correct belt tension, rotate the crankshaft two revolutions and check the tension again.
28. After ensuring that the belt tension is correct, securely tighten the tension pulley assembly mounting screws and connect the ground wire to the battery.
29. Fix the coolant hoses in the standard position and install the mudguard (or a technological lid). Install the wheel and lower the vehicle.
