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.

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).
