Place the vehicle on a two-post lift (fit the safety belts).
Disconnect and remove the battery.
Drain the refrigerant circuit (if fitted) using the filling
station.
Remove:
–the engine undertray,
–the front wheels,
–the front right and left undertrays at the end of the
wheel arches,
–the wheel arch protectors,
–the front bumper,
–the side driveshafts (see section 29 of Workshop
Repair Manual 315 "Remove and refit side
driveshafts").
Open the degassing tank.
Drain the power assisted steering circuit:
–by the low pressure hoses on the cooler,
–by disconnecting the power assisted steering high
pressure pipe (lower pipe) from the steering rack
(tool Dir. 1282-01). Take care to prevent escape.Drain the cooling circuit through the lower radiator
hose.
Remove the air filter unit.

Disconnect the lead from the engine compartment
connection unit; be sure to mark the location of the
various connections correctly.
Separate:
–a connector from the battery tray,
–the control solenoid valve from the turbocharger
regulation valve.
Fit hose pliers on the clutch master cylinder supply
pipe (on the brake fluid tank side).
Open the clutch slave cylinder bleed screw
(WARNING: you must use a counter-spanner at (C)
to compensate the effort of loosening/retightening
the bleed screw (A); see Technical Note 3345A).Disconnect:
Left side:
–the clutch slave cylinder high pressure union and
release the pipe from its clips,
–the water hoses connecting the engine to the tank
and the heater matrix element.
Right side:
–the diesel supply (1) and return (2) element from the
injection pump to the filter. It is essential that you plug
the openings with the appropriate plugs from kit
Part No.: 77 01 206 381,
–the inertia switch connector (3),
–the air conditioning circuit low pressure pipe on the
mounting bracket on the throttle body.
Under the vehicle:
–the booster pump connector; refit the electric wiring
harness to the engine.

Prepare the universal mounting tool Mot. 1390 and
position it beneath the engine and transmission
assembly (two people).Remove:
–the right-hand suspended mounting cover,
–the travel limiter linkage located just behind this
cover,
–the left-hand suspension axis mounting nut.
Gently raise the vehicle in relation to the engine (two-
person operation).
IMPORTANT: when lifting, hold on to the gearbox
control cables to prevent them from becoming trapped
and being damaged.

REFITTING - Special points
Pre-position the gearbox control cables.
Position the engine/gearbox assembly in its
compartment. Check the rear of the gearbox in relation
to the sub-frame.
Fitting suspended mountings: see section 19
"Suspended mountings".
Tighten all the bolts, nuts and studs to the
recommended torques.
Refitting is the reverse of removal.
Press the brake pedal several times to bring the
pistons into contact with the brake pads.
Reprogram all the components deprogrammed by
disconnecting the battery.
Fill the refrigerant circuit using the filling station (see
section 62 "Air conditioning").
Refrigerant fluid R134a: 800 ± 20 g.
Carry out:
–filling and bleeding of the cooling circuit (see
section 19),
–filling and bleeding of the power assisted steering
circuit,–bleed the hydraulic clutch circuit.
Damage to the union leads to replacement of the
master cylinder, and thus removal/refitting of the
gearbox.IT IS ESSENTIAL THAT YOU FOLLOW THE
BLEEDING METHOD GIVEN BELOW
VERY IMPORTANT:
When bleeding use a 19 mm ring spanner to
immobilise the rotating union (C) while tightening
and loosening the bleed screw (A) so as not to
damage the slave cylinder and the union.

BLEEDING METHOD TO BE USED:
(for two people).
1) Filling the circuit:
Check that the clutch pedal is in the top position; put
it in this position and hold it by hand if necessary.
Fill the hydraulic circuit by connecting a filling system
and applying pressure to the tank, open the bleed
screw (A) (always compensate for the force using a
counter-spanner) and allow a little fluid to escape
(approximately 0.5 l) through a transparent tube
connected to the bleed screw. Close the bleed
screw.
2) Final bleeding of the circuit:
One operator slowly disengages fully and keeps the
pedal depressed. Wait approximately ten seconds in
this situation. With the pedal still depressed, a
second operator opens the bleed screw briefly (A).
With the bleed screw closed again, the operator
inside the vehicle releases the clutch pedal and
slowly lifts it to top position by hand (It is normal that
the pedal does not return independently in this
configuration).
After a few seconds repeat the operations described
above in 2) as often as required until no more
bubbles escape when bleeding. Then repeat these
operations five times to ensure that the system has
been bled correctly.
These repeated bleedings allow the slave cylinder to
eject all the air trapped in any section between the
stop and the bleed screw and which has not been
"cleaned" by the flow of liquid when refilling using the
traditional pressurisation system.
An air bubble in the circuit, no matter how small, may
lead to operating faults such as: incorrect pedal
return, crashing of the gears,..., which may lead to
incorrect fault finding and unnecessary replacement
of a component in the clutch circuit.
