CHECKING THE FUEL PRESSURE
SPECIAL TOOLING REQUIRED
Mot. 1311-01 Fuel pressure test kit (with a pressure
gauge 0; + 10 bar tool kit)
Mot. 1311-05 Junction tool (for union K)
Mot. 1311-06 Tool for removing fuel supply unions
IMPORTANT : during the opening of the fuel cir-
cuit , be sure to use a cloth to avoid possible pro-
jections of fuel due to the residual pressure.
Disconnect the fuel supply pipe using the tool
Mot. 1311-06 with the largest section (see method
described in section 13 "Injector gallery").
Connect tool Mot. 1311-05 to the injector gallery,
then reconnect the fuel supply pipe to the tool
itself.

The pressure must be 3 bars ± 0,2.
By applying a pressure of 500 mbars to the
pressure regulator, a fuel pressure of 2.5 bars ±

Monitoring mode
Water temperature≥ 101°C
Coolant temperature ≤ 96°C Cooling fan assembly control time
≥ 10 minutes
Cooling fan assembly stops
Exit from monitoring mode
The monitoring mode is left 2 minutes after switching off the ignition in cases where the coolant
temperature is not greater than or equal to 101°C or once the coolant temperature falls below 92°C.

On this type of vehicle, the replacement of the
solenoid valve and of the coded electronic unit (A)
requires the removal of the injection pump from
the engine.
REMOVAL
With the pump on the bench, remove the protec-
tive fittings at (B).
These are secured by shear bolts which may be re-
moved either :
- using a small cold chisel or a punch and hitting
on the conical heads of bolts (C), (D) and (E)
to loosen them,
- using tool Mot. 1372 for bolt (F), drilling it
using the 4 mm diameter drill (drilling depth
approximately 4 mm) and the large diameter
drilling guide tube on the fitting side (2).
Use extractor (3) and its handle to remove it .
REFITTING
Tighten the fuel cut off solenoid valve to a torque
of 2 daN.m.
Refit a heat shrink cover on the fuel cut off sole-
noid, ensuring the wiring is correctly routed.
Refit the fittings using shear bolts and observing
their location and that of the spacers,
(depending on fitting).
IMPORTANT : using a torque wrench, tighten the
bolts, then remove the bolt heads by bending
them using a tube inserted in the bolt heads.
Location of bolts :
D :
∅ 5 x 25 mm ; torque =0.55 daN.m
C and F :
∅ 6 x 40 mm ; torque =1.2 daN.m
E :
∅ 5 x 33 mm ; torque =0.55 daN.m
Refit the cable of the fast idle speed LDA and
tighten the cable grip, leaving 2 mm play.
Refit the injection pump on the engine.

Remove :
- the fuel supply pipe (A),
- the fuel return pipe (B),
- the pump connector (C),
- the accelerator cable (D),
- the vacuum pipe (E) connected to the fast
idle speed LDA,
- the high pressure wiring loom using tool Mot.

Fit tool Mot. 1200 or Mot. 1317 , for retaining the
pump pulley.
12410R
Inserting a torx screwdriver in the gaps of the
RAM pulley, slacken:
- the three bolts mounting the pump
- the central nut securing the pump shaft to the
RAM pulley.
Slacken the central nut and all three of the bolts
mounting the pump until they are completely
free.
Extract the pump.
REFITTING
Clean the pump shaft very thoroughly, using sol-
vent to eliminate all trace of grease.
Refit the pump.
Tighten the three bolts mounting the pump .
Pretighten the central nut of the pump to 2
daN.m.
IMPORTANT : it is vital to carry out a pretighte-
ning operation before the final tightening; tigh-
ten the central pump nut to a torque of 4.5
daN.m.
Carry out the timing operations (see "Pump -
Timing").
For all other operations, refitting is the reverse of
removal.
