CYLIDER HEAD TIGHTENING A ND R ETI GHTENING

ATTENTION!

In order to obtain a correct tightening of the cylinder head screws, clean the attachment holes of the cylinder head of oil or coolant liquid, by means a syringe. Grease the thread of screws with engine oil.

CYLINDER HEAD TIGHTENING

Tighten at the required moment (6,5 daNm) observing the tightening sequence from the drawing.

CYLINDER HEAD RE TIGHTENING

Retightening of the cylinder head is performed as follows:

- for new vehicles at the 800 – 1000 km

check u;

- in case of engine repairing, which implies the cylinder head dismounting, after 800 – 1000 km driving;

- every 10.000 km.

For retightening, loose the screw (1) with 1/4 rotation, after that retighten it to the

require moment:

- 6,5 daNm at warm (50 min. after engine shopping);

- 5,5-6,5 daNm at cold.

Repeat this operation also for the other screws, observing the sequence showed in the

drawing.
