REMOVAL
Put the vehicle on a two post lift.
During this operation, it is necessary to secure the
vehicle to the lift using a strap to prevent the vehicle
from losing balance.
See Technical Note 2988A for the procedure for fitting
the strap. TIGHTENING TORQUES (n daN.m)

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).

WARNING
In order to eliminate any risk of damaging the
rotary switch under the steering wheel, observe
the recommendations below:
!Before the steering column and the steering
rack are uncoupled, the steering wheel MUST
be immobilised with the wheels straight for the
duration of the operation using a "steering
wheel locking tool".
!If there is any doubt regarding the correct
alignment of the rotary switch, the steering
wheel must be removed so that the alignment
procedure described in the "AIRBAG" section
can be applied.
REMINDER: in this case, only qualified
personnel who have received training may carry
out the operation.

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.

REFITTING
Engine cold (ambient temperature).
Check that pin Mot. 1054 is in place.
Fit the timing belt by aligning the belt markings with
those of the camshaft, injection pump and crankshaft
sprockets.
Bring the tension wheel into contact with the belt by
tightening a bolt to the inner timing cover.
Remove pin Mot. 1054.Apply a pretensioning torque using Mot. 1543 (fitted
with cover N˚ 3) by using a torque wrench adjusted to
a torque of 1.1 daN.m on the edge of the belt to be
measured.

Fit the reading head of Mot. 1505 and carry out the
measurement, then adjust the tension using the bolt
in contact with the belt until pretension value
T1 = 68 ± 3 Hertz is reached.
Tighten the tensioner.
Turn the crankshaft four times and reposition the
timing at top dead centre using the pin.
Remove pin Mot. 1054.
Apply a pretensioning torque using Mot. 1543 (fitted
with cover N˚ 3) by using a torque wrench adjusted to
a torque of 1.1 daN.m on the edge of the belt to be
measured.
Fit the reading head of Mot. 1505 and carry out the
measurement, then adjust the tension using the bolt
in contact with the belt until pretension value
T2 = 61 ± 5 Hertz is reached.
Tighten the tension wheel nut to a torque of 5 daN.m.
NOTE: it is vital that you tighten the tension wheel
nut to torque to avoid any slackening which may
cause damage to the engine.
Never refit a belt once removed, but replace it.
Replace the crankshaft pulley bolt and tighten it to a
torque of 2 daN.m plus an angle of 115˚ ± 15˚.
See section 07 "Accessories belt tension" for the
tension value for fitting the power assisted steering
belt.The belts on vehicles fitted with air conditioning are
tensioned by bringing the automatic tensioner plate to
a stop at bolt (B), without forcing it, using a 9.35 mm
square.

REFITTING (special notes)
Fit the cylinder head gasket. This is centred by two
dowels.
Bring the pistons to mid-stroke position to prevent
them from coming into contact with the valves as the
cylinder head is tightened.
Centre the cylinder head on the dowels.
Lubricate the threads and under the heads of the
mounting bolts.
Tighten the cylinder head using an angular tightening
wrench (see section '07 "Tightening the cylinder
head").

mounting
Offer up the three touching bolts then apply a torque of
2.5 daN.m respecting the order shown below.
Refitting is the reverse of removal.
Refit the timing belt, (see procedure described in
section 11 "Timing belt").
Fill and bleed the cooling circuit, (see section 19
