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.

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.

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.
