REFITTING
I - REFITTING PREPARATION OPERATION
aparts always to be replaced: Turbocharger nut.
aparts always to be replaced: seal between ex-
haust manifold and turbocharger.
aparts always to be replaced: Turbocharger cool-
ant pipe if replacing the turbocharger.
aUse a SURFACE CLEANER (see Vehicle: Parts
and consumables for the repair) (04B, Consuma-
bles - Products) to clean and degrease the sealing
surfaces:
-of the turbocharger (if being reused),
-of the exhaust manifold.
II - REFITTING OPERATION FOR PART
CONCERNED
aRefit:
-a new turbocharger seal,
-the turbocharger,
-new turbocharger nuts.
aTorque tighten the turbocharger nuts (21 N.m).
1 - If replacing the turbocharger
aRefit:
-the turbocharger cooling pipes,
-the turbocharger cooling hollow pipe bolts,
-the turbocharger cooling pipe bracket bolts,-the air outlet pipe of the air filter unit.
aTighten the clip of the air outlet pipe on the air filter
unit.
aTorque tighten:
-the turbocharger cooling pipe hollow bolts (30
N.m),
-the turbocharger cooling pipe bracket bolts (10
N.m).
a
aConnect the turbocharging pressure regulation
pipes.
aClip on the clips of the turbocharging pressure regu-
lation pipes.
2 - If the turbocharger is not being replaced
aClip the wiring onto the turbocharger coolant rigid
pipe strut.
aConnect:
-the turbocharger discharge air pipe,
-the oil vapour recirculation pipe on the air filter unit
air outlet pipe,
-the petrol vapour recirculation pipe on the air filter
unit air outlet pipe,
-the turbocharging regulation solenoid valve con-
nector from the turbocharger,
-the ignition coil connector.
aTighten the turbocharger discharge air pipe clip.
aRefit the turbocharger oil supply pipe (see 12B, Tur-
bocharging, Turbocharger oil pipe: Removal -
Refitting, page 12B-12) .
aRefit the turbocharger cooling pipe strut bolt.
aConnect the turbocharger cooling hoses.
aFit the turbocharger cooling hose clips using the tool
(Mot. 1448).
aRemove the tools (Ms. 583).
aRefit the turbocharger oil return pipe (see 12B, Tur-
bocharging, Turbocharger oil pipe: Removal -
Refitting, page 12B-12) . WARNING
Ensure that no foreign bodies enter the turbine or
compressor during the refitting operation.
Check that the turbocharger oil return pipe is not
partially or completely blocked by scale. Check
that there are no leaks. If there are, replace the
part.Note:
Dur ing this operation, use a set of feeler gauges
to ensure that there is a minimum clearance of 3
mm between the turbocharger water outlet pipe
and the turbocharger heat shield.

CHECK
aRemove the front engine cover.
aPrime the fuel circuit with the manual priming pump
until the disconnected pipes are filled with fuel (auto-
matic degassing).
aCheck that there are no fuel leaks.
aConnect the Diagnostic tool to the vehicle.aDeal with present faults,
aActivate command AC029 “high pressure circuit
sealing test”.
aCheck that there are no fuel leaks.
aDeal with the causes of any possible leaks.
aUse the Diagnostic tool to check for stored faults;
deal with these and clear them as necessary.
aDisconnect the Diagnostic tool.
aRefit the engine cover. Equipment required
Diagnostic tool
Note:
Check that there are no diesel leaks after each
operation.
Note:
The Diagnostic tool can be used to test the high
pressure circuit with the engine running. This
command can be used to run fault finding on a
leak due to an incorrectly fitted or tightened
union. This command only works if the engine
coolant temperature is greater than 60˚. The fault
finding procedure will not reveal small leaks due
to incorrect tightening.
IMPORTANT
Consult the safety and cleanliness advice and
operation recommendations before carrying out
any repair (see 13B, Diesel injection, Diesel
injection: Precautions for the repair, page
13B-1) .Note:
Certain faults will prevent this test from being
carr ied out: deal with them first.
Note:
The engine automatically runs a cycle of four
acceler ations and decelerations to lower the rail
pressure.
Note:
Do not leave anything on the engine compart-
ment dur ing the test phase (significant vibration).
