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.

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.

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.

MAINTENANCE
The principal maintenance operations on this
assembly are:
–replacing the ignition spark plug (5),
–cleaning the filter at the pump inlet (13) (see
page 61-2).
REMOVING - REFITTING COMPONENTS
FUEL PUMP INLET FILTER (13)
Remove the front bumper.
Rotate the pump (12) (see page 61-2) if it turns and
loosen the union covering the filter (13). Clean or
replace the filter if there is a combustion problem.
IGNITION SPARK PLUG
Disconnect and remove the heater without draining the
cooling circuit (use pliers Mot. 453-01).
Remove:
–the turbine cover (1),
–the control unit (9) and the cap (16),
–the spark plug (5) after disconnecting it.
FLAME DETECTOR
Disconnect and remove the heater without draining the
cooling circuit (use pliers Mot. 453-01).
Remove:
–the turbine cover (1),
–the control unit (9) and the cap (16).
Disconnect the flame connector by pulling the flat
terminals from the connector.
Remove the flame detector.
(WARNING: fragile part)COMBUSTION CHAMBER (4) AND EXCHANGER (3)
Remove:
–the flame detector and spark plug,
–the wiring harness fitted on the overheating
detector (8) and the temperature sensor (7),
–the turbine support (1).
Remove the combustion chamber (4) and the
exchanger (3) if necessary.
FAULT FINDING
In case of a fault, check:
–if there is fuel in the tank,
–if the fuses are intact
–if the pipes, connections and electrical unions are
intact,
–if the combustion air ducts or exhaust gas ducts are
blocked (unblock them if necessary).
In the even of combustion with the production of soot,
check:
–if the combustion air ducts or exhaust gas ducts are
blocked (unblock them if necessary),
–if there is a deposit in the exchanger (3) or the
combustion chamber (4); clean these if necessary,
–if the dosing pump flow is correct;
To do this:
●remove the bumper,
●disconnect the electric pump inlet fuel pipe (12),
from the side opposite the fuel filter (13),
●connect a pipe to the electric pump so that the flow
can be collected in a glass at the same height as
the heater,
●start the heater (if necessary, bridge the
temperature sensor located in front of the battery
screen). After approximately 40 seconds, the fuel
arrives and begins to bleed the circuit. Switch off
the ignition. Empty the glass and start again,
collecting the stabilised flow for approximately
30 seconds. Switch off the heater and measure the
quantity of fuel collected.
Normal flow: between 6.8 cm
3 and 7.8 cm3 for
90 seconds of operation.
