Filling and bleeding
There is continuous circulation in the heater matrices.
FILLING
It is essential to open the two bleed screws at the
top of the radiator and the cylinder head coolant
pipe housing outlet.
Fill the circuit through the expansion bottle opening.
Close the bleed screws as soon as the liquid starts to
flow in a continuous stream.
Start the engine (2 500 rpm).
Adjust the level by overflow for a period of about
4 minutes.
Close the bottle.
BLEEDING
Allow the engine to run for about 20 minutes at
2 500 rpm, until the engine fans(s) operate (time
necessary for automatic degassing).
Check the liquid level is at the "Maximum" marker.
DO NOT OPEN THE BLEED SCREWS WHILST THE
ENGINE IS RUNNING.
REFIT THE EXPANSION BOTTLE CAP WHILE THE
ENGINE IS WARM.

OIL CAPACITY :
–Maximum: 2.8 l
–Minimum: 2.3 l
OIL LEVEL
The oil level is adjusted using a locally manufactured
dipstick, inserting into the oil filler hole (2) (see
Technical Note 2579A).
To check the level it is necessary to remove the left
hand front wheel and the left hand wheel arch cover.
The oil can also be changed and refilled with the
recommended quantity.

2 Fuel filler cap
WARNING: the fuel filler cap (2) should not be used to
check the level by overfilling; using too much oil may
damage the seals and overheat the oil. Marks to graduate:
–B: 22 ± 0.5 mm
–C: 30 ± 0.5 mm

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.

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.

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.
