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.

Remove:
–the mounting bolt from the low pressure air
conditioning pipe bracket (3),
–the mounting bolts (4) from the throttle body on the
engine housing. Use a 13 mm dowel, a cardan joint
and small extension. If necessary, remove the pipes
to access the bolts.
WARNING: avoid loosening the four self-tapping bolts
(A) which attach the top to the unit body.Remove the connection pipe (5) between the throttle
body and the inlet manifold,
If necessary, unclip the electrical wiring in front of the
damper unit to ease the downwards release of this
unit.
REFITTING
Proceed in the reverse order from removal.
Tighten the mounting clips to 5.5 daN.m.
Check that there are no stored faults using a fault
finding tool. Erase them if necessary.

REMOVAL
Put the vehicle on a 2 post lift.
Disconnect the battery and the electrical connections
on the alternator and the air conditioning compressor.
Remove:
–the front right wheel,
–the right-hand wheel arch cover,
–the lower engine cover,
–the bumper,
–the windscreen washer tank,
–the air exchanger/throttle body unit pipe after
disconnecting it,–the accessories belt (see method on page 11-1),
–the accessories belt pulley.

Undo the four air conditioning compressor mounting
bolts and allow this to hang by its pipes.
Undo and remove the lower mounting bolt on the
alternator; undo the upper bolt without removing it,On the right-hand side below, remove the vertical
engine tie-bar mounting bolt.
Undo without removing the pre-catalytic converter
mountings on the exhaust pipe.
Remove the upper mounting bolt on the alternator by
manually lifting the engine and transmission assembly
forwards; the bolt passes just above the right hand
side member.
REFITTING
Refitting is the reverse of removal.

COOLING SYSTEM
Cooling system
Bleed the cooling circuit, the air conditioning circuit
(see special manual for air conditioning)
Open the relay unit at the top left of the ring and
disconnect the electric wiring harness from the cooling
system at the radiator.
Remove the front bumper, the radiator grille and the
radiator grille rack.
Remove the mounting bolts on the radiator
convergents and fold them to remove it from the
bottom.
Disconnect the air conditioning air hoses at the
compressor for the compressor/condenser connection
and at the quick-release union for the bottle/bulkhead
connection.
When removing/refitting the cooling system, it is
recommended that you do not disconnect the
connections between the high pressure pipes and the
condenser/bottle unit as the seals are special and
delicate to replace.Set the radiator cross member on a table with shims
and release the mountings.
Remove the two mounting bolts from the cross
member on the tips of the side members.
Lift the vehicle while holding the cooling system to
prevent damage (operation for two people).
REFITTING
Refitting is the reverse of removal.
Top up the coolant and the air conditioning circuit.
Replacement of the air conditioning condenser or the
cooling exchanger requires the removal of the cooling
system.

Additional heating
OPERATING PRINCIPLE
The vehicle with a G9T engine is fitted with an additional heating system as an option in some countries (Germany,
Nordic countries...). This comprises an engine coolant heater, mainly for starting when cold.
The heater is switched on if the following three conditions are met:
–starting the engine,
–air intake temperature less than 5 ˚C,
–coolant temperature less than 75 ˚C.
The heater is usually switched off when the engine is stopped or the coolant temperature reaches 85 ˚C.
The temperature is measured inside the heater.
The driver does not control operation.
The system is fitted with several safety features (see page 61-3).
The heater is connected as the outlet of the thermoplunger unit on the coolant circuit and operates independently of
this. It is fitted outside the left-hand side member in the front bumper.

662AIR CONDITIONING
Air conditioning compressor
The G9T engine vehicle is fitted with a variable
geometry air conditioning compressor; that is, the
compressor adapts the flow of refrigerant fluid
according to a difference in pressure between the
compressor inlet and outlet, and not according to the
temperature read by the sensor (omission of the
evaporator sensor).
The system cannot be adjusted
The pressure relief valve is still present but calibrated
differently.
REMOVAL
Put the vehicle on a 2 post lift.
Disconnect the battery.
Drain the refrigerant circuit (see special "AIR
CONDITIONING" manual).
Remove:
–the front right wheel,
–the right-hand wheel arch cover,
–the lower engine cover,
–the air exchanger/throttle body unit pipe after
disconnecting it,.
–the accessories belt (see methods in section 07
"Accessories belt"),Unscrew the two mounting clamps on the compressor
refrigerant pipes and carefully plug the openings.
Unscrew the four mounting bolts from the air
conditioning compressor and remove it.
REFITTING
Refitting is the reverse of removal.
