    Remove all top covers of the engine. Disconnect the electromagnetic valve of an adsorber of the fulfilled gases and remove a forward right air line. Mark with a chalk or a felt-tip pen a rotation direction on клиновом a belt.

Change of a direction of rotation of the belt which was in work, can lead to its rupture.

    Ослабьте wedge a belt also remove it. For this purpose incline the tension device the suitable lever, for example, 3299/3299/1 in a rotation direction.



    Installation is carried out in sequence, the return to removal. Thus at first put on wedge a belt a pulley of a cranked shaft and then on a tension roller.
