using an allen spanner at «d».
Should this fail, repeat the operation to tension the timing belt.
Hold the tensioner roller (18).
Tighten the tensioner roller fixing nut to 3,7 ± 0,3 m.daN.
Check the position of the tensioner roller (the alignment of the marks «g» and «h» has to be correct).

Rotate the crankshaft six times (clockwise).
IMPERATIVE: Never rotate the engine backwards.
WARNING: Do not touch or damage the track of the target of the engine speed sensor (14).
Peg the crankshaft, using tool [3].
Check the position of the tensioner roller (the alignment of the marks «g» and «h» has to be correct).
If this is not the case, repeat the operation to tension the timing belt.
Peg the camshaft pulley, using tool [2].
IMPERATIVE: Should it be impossible to peg the camshaft, check that the offset between the
camshaft pinion hole and the pegging hole is not more than 1 mm. If the value is not correct,
