sequence for cylinder head bolts
Note: Loosen the bolts in the reverse order when removing the cylinder head.
R etorquing of cylinder head bolts
Retorque after 1 000-2000 km (600-1200 miles). The en­
gine
should be cold or almost cold.
Tighten each bolt separately in correct sequence (see
above
illustration).
Tighten bolt 90°. Note: This should be done in one move ­
ment without stopping.
Bolts should not be slacken ed
first.

g
hten cylinde r h ea d bolts in stages
Remove oil and dirt from bolt holes. Oil left in holes will
reduce the pressure on the cylinder head gasket.
Bolt threads and washers must however be oiled, other-
wise
frictional forces will be too large.
Use new bolts .
Tighten in six stages in sequence shown above
Stage 1 = 40 Nm (30 ft Ib)
2 = 60 Nm (44 ft. Ib)
3 = 75 Nm (55 ft. Ib)
4 = tighten 180°. Note: This should be done in
one movement without stopping .
5
= run engine until oil temperature is at least
+50°C (112°F).
6 = tighten 90°. Note: This should be done in one
movement without stopping
