Wait 3 minutes settling time.
Tightening the cylinder head:
– cylinder head tightening is carried out in stages, and
the following procedure is applied successively to
bolts 1-2 then 3-4, 5-6, 7-8 and 9-10,
– slacken bolts 1-2 until they are completely free,
– tighten bolts 1-2 to 2.5 daN.m, then angle tighten to
213 ±7˚,
– repeat the slackening and tightening operations for
bolts 3-4, 5-6, 7-8 and 9-10.
