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.
