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.

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.
1 Drain plug
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

Removal - refitting
The method for removing/refitting the PK1 G9T
gearbox is the same as for the G8T engine.
See Workshop Repair Manual 315 section 21
"Transmission: removing/refitting the PK1
gearbox".
Please observe the recommendations for bleeding the
hydraulic clutch system given in Technical Note
3345A when refitting.
IMPORTANT:
The TDC sensor (1) may be moved during the gearbox
removal/refitting operation.
If necessary, push this until it is in contact with the
backing plate.
Too great a gap could cause a starting fault which is
not visible on the fault finding tool.

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.

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.
