WARNING
Before fitting a new high-pressure pipe, lightly
lubricate the nut threads with the oil from the
applicator provided in the new parts kit.
Be careful not to allow oil into the high-pressure
pipe.
Do not lubricate high-pressure pipes supplied
without an applicator, as these high-pressure
pipes are self-lubricating.

REMOVAL
I - REMOVAL PREPARATION OPERATION
aRemove the front engine cover.
aDisconnect the battery ( (see Battery: Removal -
Refitting) ).
aProtect the alternator from fuel outflow.
aDisconnect:
-the heater plug connectors (1) from cylinders 3 and
4,
-the injector connectors (2) from cylinders 3 and 4.II - OPERATION FOR REMOVAL OF PART
CONCERNED
aDisconnect the fuel temperature sensor connector.

WARNING
Do not blast with compressed air once the fuel
circuit is open, otherwise impurities may enter
the system. Only use cleaning cloths.
Note:
Do not lubricate the seals with grease or old die-
sel fuel.

-cleaning cloths,
-set of K9K blanking plugs (DELPHI injection).
CHECK
aRemove the front engine cover.aDisconnect:
-the diesel return pipes (1) on the injectors,
-the diesel return pipe (2) on the Venturi fitted on the
high pressure pump.
aFit the correct blanking plug on the Venturi. Special tooling required

IMPORTANT
Consult the safety and cleanliness advice and oper-
ation recommendations before carrying out any
repair (see 13B, Diesel injection, Diesel injec-
tion: Precautions for the repair, page 13B-1) .
