release the pipe from its clips,
–the water hoses connecting the engine to the tank
and the heater matrix element.
Right side:

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.

TECHNICAL SPECIFICATIONS
The heater is fitted with an igniter appropriate for the
vehicle fuel.
It operates in two power levels:
–1˚) Low speed:
●Power: 1600 Watts,
●Fuel consumption: 0.2 l/hour.
–2˚) High speed:
●Power: 3300 Watts.
●Fuel consumption: 0.4 l/hour.
When the engine is started, the heater is operated at
high speed; circulation of the coolant inside the
exchanger is ensured by the vehicle coolant circuit.
A Temperature (˚C)
B Minutes
–Range a:
High speed.
–Range b:
Low speed.
–Range c:
Heater stop.
Coolant temperature measured inside the heater.SAFETY SYSTEMS
The system is fitted with several safety features; it cuts
out:
–if the difference in coolant temperature read by the
two internal heater sensors reaches 15 ˚C,
–if the coolant temperature reaches 120 ˚C (different
safety features than reading 85˚),
–if the flame detector does not detect combustion,
(notably the heater fuel pump),
–if the battery voltage is greater than 16 volts or less
than 10 volts.
Other safety devices:
–when the heater does not light 90 seconds after the
supply of fuel is started, the starting procedure is
repeated. If, during the following 90 seconds the
system still does not start, the emergency stop is
engaged.
–if the flame extinguishes during operation the starting
procedure is repeated. If the heater does not start up
in the following 90 seconds, the emergency stop is
engaged.
–in the event of overheating (lack of coolant,
incorrectly drained cooling circuit...), the overheating
switch reacts, the fuel supply is stopped and the
emergency stop is engaged. The heater can be
restarted after the source of overheating has been
eliminated and the heater has cooled sufficiently.
SWITCHING OFF
To temporarily disconnect the heater (operation with
engine running in an enclosed space, noises when
cold,...), disconnect the connector (15) (page 61-2).
If possible, check that the heater engages after it is
reconnected.
The main F49 (70 A) fuse on the engine
intercommunication unit supplies the additional
heating system.
