jections of fuel due to the residual pressure.
REMOVAL
Disconnect the battery.
Remove the air filter.
Remove:
- the fuel supply pipe (1)
- the fuel return pipe (2)
- the fuel pressure regulator pipe (3) .

REFITTING
Replace the O rings at the base of the injector (if
the injector has been removed, also replace the
seal which is level with the injector head).
To ensure that the fuel supply unions are correct-
ly fastened, it is necessary to hear a"click" sound
whilst fastening.
For all other operations, refitting is the reverse of
removal .

DIESEL EQUIPMENT
Pre-postheating control
13
The pre-postheating function is controlled by the
computer, which controls the preheating plug re-
lay housing.
1) Ignition - Preheating
The preheating process is divided in two
phases :
a) Variable preheating
This is dependent on the coolant tempera-
ture, on the battery voltage and on alti-
tude (internal computer sensor) when the
ignition is switched on (the preheating
warning light illuminates).b) Fixed preheating
After the preheating warning light has
extinguished (variable preheating), the
plugs remain fed for 8 seconds before the
engine is started.
2) Starting the engine
During the action of the starter motor, the
four plugs are fed continuously.
3) Engine running - Postheating
The postheating also may be divided in two
phases:
a) Fixed postheating
After starting the engine, the plugs are
supplied simultaneously for a period of 10
seconds.
b) Variable postheating
Variable postheating begins when fixed
postheating ends. The time during which
the plugs are fed (continuously) depends
upon :
- the coolant temperature
- the engine speed ,
- the load (load potentiometer on pump
lever ).
Maximum preheating limit (battery vol-
tage lower than 9.3 volts and altitude hi-
gher than 2 000 m).
Minimum preheating limit (battery
voltage greater than 10.5 volts altitude
lower than 350 m).

Coolant temperature °C0204060
Variable postheating may be interrupted :
- permanently, if the coolant temperature is >
60°C,
- temporarily , if the unit receives full load
information for more than 3 seconds; the
function is established once again if the
engine returns to idle speed or low load,
- temporarily again if the battery voltage is
>16 V; the function is restored if Ubatt
< 15 V.
In all cases, the total duration of the postheating
function will never exceed 3 minutes.
