-the bolts (23) from the exhaust gas recirculation as-
sembly,
-the exhaust gas recirculation assembly.
REFITTING
I - REFITTING PREPARATION OPERATION
a Always replace the seals on the air inlet metal tube.
a Use ABRASIVE PADS to clean the joint faces of the
exhaust gas cooler mounting on the gearbox end.
a Use SURFACE CLEANER (see Vehicle: Parts
and ingredients for the repairwork) (04B, Consu-
mables - Products) to clean and degrease:
-the housing of each air inlet metal tube seal,
-the housing of the air inlet metal tube in the cylinder
head,
-the housing of the air inlet metal tube in the ex-
haust gas cooler mounting on the gearbox end.
a parts always to be replaced: Exhaust gas recir-
culation rigid pipe (11,07,01,08).
a parts always to be replaced: Exhaust gas recir-
culation pipe seal (11,07,01,15).
II - REFITTING OPERATION FOR PART
CONCERNED
a Fit the new exhaust gas recirculation rigid pipe with
a new seal on the exhaust gas recirculation assem-
bly.
a Refit the exhaust gas recirculation assembly equip-
ped with the exhaust gas recirculation rigid pipe on
the cylinder head.
a Fit without tightening:
-the bolts of the exhaust gas recirculation assembly
on the cylinder head,
- the bolts of the exhaust gas recirculation rigid pipe
bracket on the cylinder head,
- the exhaust gas recirculation rigid pipe bolts on the
exhaust manifold.
a Tighten to torque:
- the bolts of the exhaust gas recirculation as-
sembly on the cylinder head (25 N.m),
- the bolts of the exhaust gas recirculation rigid
pipe bracket on the cylinder head (25 N.m),
- the bolts of the exhaust gas recirculation rigid
pipe on the exhaust manifold (36 N.m),
- the bolts of the exhaust gas recirculation rigid
pipe on the exhaust gas recirculation assembly
(12 N.m).
a Refit the exhaust gas recirculation assembly.
a Tighten to torque:
- the bolts of the exhaust gas recirculation as-
sembly (25 N.m),
- the bolts of the exhaust gas recirculation as-
sembly mounting (25 N.m).
III - FINAL OPERATION
a Connect the cooling hoses of the exhaust gas cooler
cover.
a Fit the clip on each cooling hose of the exhaust gas
cooler cover using the tool (Mot. 1448).
WARNING
Do not scrape the joint faces of the aluminium,
any damage caused to the joint face will result in
a risk of leaks.
WARNING
To ensure proper sealing, the gasket surfaces
must be clean, dry and not greasy (avoid any fin-
ger marks).
