Note:
T ake care not to damage the exhaust gas inter-
cooler pressure faces on their mountings to pre-
vent any coolant leaks.
a Use ABRASIVE PADS to clean the exhaust gas in-
tercooler pressure faces between the exhaust gas
intercooler and the exhaust gas recirculation mount-
ings.
a Degrease the pressure faces with SURFACE
CLEANER (see Vehicle: Parts and consumables
for the repair) (MR 415, 04B, Consumables - Prod-
ucts) and CLEAN CLOTHS.
a Always replace:
- the rigid exhaust gas recirculation pipe,

1 - Refitting preparation operation for the exhaust
gas recirculation mounting on the gearbox side
a Always replace the exhaust gas recirculation mount-
ing seal on the gearbox side.
If replacing the exhaust gas recirculation mounting
on the gearbox side
a Use ABRASIVE PADS to clean the pressure faces
between the exhaust gas intercooler coolant circula-
tion cover and the exhaust gas recirculation mount-
ing on the gearbox side.
a Degrease the pressure faces with SURFACE
CLEANER (see Vehicle: Parts and consumables
for the repair) (MR 415, 04B, Consumables - Prod-
ucts) and CLEAN CLOTHS.
a Always replace the exhaust gas intercooler coolant
circulation cover seals.
a Refit:
- the new exhaust gas intercooler coolant circulation
cover seals,
- the exhaust gas intercooler coolant circulation cov-
er,
- the exhaust gas intercooler coolant circulation cov-
er bolts.
a Tighten the exhaust gas intercooler coolant circula-
tion cover bolts.
a Refit the exhaust gas recirculation solenoid valve
(see 14A, Antipollution, Exhaust gas recircula-
tion solenoid valve: Removal - Refitting, page
14A-11) .
2 - Refitting preparation operation for the exhaust
gas recirculation mounting on the timing end
a Always replace the exhaust gas recirculation mount-
ing seal on the timing end.
