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

Tighten bolt 90°. Note: This should be done in one move
ment without stopping.
Bolts should not be slacken ed

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
