The belts on vehicles fitted with air conditioning are
tensioned by bringing the automatic tensioner plate to
a stop at bolt (B), without forcing it, using a 9.35 mm

See section 07 "Accessories belt tension" for the
belt tension value for vehicles without air conditioning.
NOTE: never refit a belt once it has been removed,
but replace it.
