Tightening the cylinder head
METHOD FOR TIGHTENING THE CYLINDER HEAD
REMINDER: in order to tighten the bolts correctly, use
a syringe to remove any oil which may have entered
the cylinder head mounting bolt holes.
All the cylinder head bolts must always be changed
after removal. There is no cylinder head retightening
operation.
Preseating the gasket
Tighten all the bolts to 3 daN.m, then angle tighten to
100˚ ± 4˚ in the order shown below.
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.
There is no cylinder head retightening operation.

Fit tool Mot. 1040-01 under the engine sub-frame.
Lower the lift until the tool touches the ground.
Remove the sub-frame mounting bolts and take out
the engine and transmission assembly by lifting the
body.
When starting to lift the body, ensure that the catalytic
converter is removed and extract the radiator from its
upper mountings (then place it on the sub-frame).
NOTE: for any operation requiring the engine, gearbox
and sub-frame assembly to be separated, take care to
mark the position of tool Mot. 1159 on the sub-frame.REFITTING
The alignment of the sub-frame with the body will be
made easier by positioning two threaded rods
Mot. 1233-01 in the two front mountings of the sub-
frame on the body.
When lowering the body onto the engine - gearbox
assembly, ensure that the catalytic converter is
refitted.
Tighten the sub-frame mounting bolts to a torque of:
– 6.2 daN.m at the front,
–10.5 daN.m at the rear.
See section 19 "Suspended engine mounting" for
the tightening torques for the engine and gearbox
assembly mountings.
Refitting is the reverse of removal.
Refit the heat shields correctly.
Apply Loctite FRENBLOC to the caliper mounting
bolts and tighten them to the recommended torque.
Press the brake pedal several times to bring the
pistons into contact with the brake pads.
Fill:
– the engine and gearbox with oil (if necessary),
– the cooling circuit and bleed it (see section 19
"Filling - bleeding").
Fill the refrigerant circuit using the filling equipment (if
fitted).

REFITTING
Put a drop of RHODORSEAL 5661 at (A) (on either
side of bearing N˚ 1), and at (B) (at the intersection of
the crankshaft closure panel and the cylinder block).
Refit the sump with a new gasket, pre-tightening it to a
torque of 0.8 daN.m, then tighten it finally to a torque
of 1.5 daN.m in the order recommended below.
Fill the engine with oil.

– the bolts (1) and (2),
– the alternator mounting bolts and remove the
alternator, then remove the bolts (3).
Loosen the exhaust pipe clamp mounting.
Remove:
– the catalytic converter mountings on the pre-catalytic
converter,
– the pre-catalytic converter stay (1),
– the mounting (6),
– the oil supply pipe at (7) and remove towards the
bulkhead,
– the pre-catalytic converter mountings to the turbo,
– the catalytic converter removing the engine towards
the cooling system,
– the oil return pipe (8),– the bolt (9) and loosen the other mounting bolts on
the lower timing cover without removing them,
– cylinder head bolts.
Release the cylinder head by setting aside the lower
part of the camshaft housing, without causing the
cylinder head to turn, since this is centred by the two
dowels.

CLEANING
It is very important not to scratch the gasket faces
of any aluminium component.
Use the Décapjoint product to dissolve any part of the
gasket which remains attached.
W ear gloves whilst carrying out the following
operation.
– Apply the product to the parts to be cleaned; wait
about ten minutes, then remove it using a wooden
spatula.
W e must draw your attention to the care which
must be taken during this operation, to prevent
any foreign bodies from being introduced into the
oil ways (ducts located in the cylinder block and in
the cylinder head).
CHECKING THE GASKET FACE
Check for gasket face bow using a straight edge and a
set of shims.
Maximum deformation: 0.05 mm.
No regrinding of the cylinder head is permitted.
Check the cylinder head for cracks.Checking piston protrusion
Clean the piston heads in order to eliminate any traces
of deposits.
Turn the crankshaft in its operating direction, to bring
piston n ° 1 close to TDC.
Fit tool Mot. 252-01 on the piston.
Fit the tool Mot. 251-01 fitted with a gauge on the
pressure plate Mot. 252-01 (the dial gauge measuring
pin being in contact with the cylinder block) and look
for the TDC of the piston.
NOTE: All measurements are to be carried out in the
longitudinal axis of the engine, in order to eliminate
any errors due to tilting of the piston.
Max. piston protrusion: 0.72 ± 0.077 mm

REMOVAL
NOTE: to slacken the turbocharger mounting nuts
more easily on the exhaust manifold, it is useful to
spray a releasing agent on the nuts when still hot, just
before removal.
Disconnect the battery.
Remove the engine cover.
From below
Remove:
– the engine undertray,
– the mounting stay (5),
– the two bolts fixing the turbo oil return pipe (7) to the
engine,
– the lower turbo mounting nut on the exhaust
manifold.
