15. Release the electrical wiring tube (arrow on resist illustrations), remove the bolt (1) and remove the drive belt tensioner from the accessory bracket.
24.15 Removing the drive belt tensioner
16. Installation is carried out in the reverse order. When installing the tensioner (1 per resist. illustrations) insert it into the auxiliary bracket (3) and tighten the bolt (5). ledge (2) must fit into the hole in the accessory bracket. After installation, adjust the position of the supports (see Section 23).
