DIESEL INJECTION
Diesel injection: Precautions for the repair

I - RISKS RELATING TO CONTAMINATION
The high-pressure direct injection system is highly sen-
sitive to contamination. The risks caused by contami-
nation are:
-damage to or destruction of the high pressure injec-
tion system,
-a component seizing,
-a component not being properly sealed.
All After-Sales operations must be performed under
very clean conditions. Having carried out an operation
in good conditions means that no impurities (particles a
few microns in size) have penetrated the system during
dismantling.
The cleanliness principle must be applied from the filter
to the injectors.
What are the sources of contamination?
-metal or plastic swarf,
-paint,
-fibres:
•cardboard,
•brushes,
•paper,
•clothing,
•cloth,
-foreign bodies such as hair,
-ambient air,
-etc.
1 - Cleaning cloths
Use lint-free cleaning cloths (see Vehicle: Parts and
consumables for the repair) (04B, Consumables -
Products).
It is prohibited to use cloths or ordinary paper towels:
these produce lint and lose fibres, which then contami-
nate the fuel circuit.
Each cloth must only be used once.2 - Blanking plugs
The blanking plugs are used to cap the fuel circuit once
it is opened and to therefore prevent contaminants
from entering.
A set of blanking plugs should be used once only and
used plugs must be discarded after use: once used,
the plugs are soiled and cleaning them is not sufficient
to make them reusable.
Unused plugs must also be discarded and must not be
used when carrying out work on an injection system.
Part number for set of blanking plugs: (see Vehicle:
Parts and consumables for the repair) (04B, Con-
sumables - Products).
3 - Protective bags
Use hermetically-resealable plastic bags, using adhe-
sive tape, for example, to store components which will
be refitted and reused. Stored parts will therefore be
less subject to the risk of contamination.
These are single-use bags: after use they must be dis-
carded.
4 - Cleaning products
Two cleaning products can be used:
-an injector cleaner (see Vehicle: Parts and consum-
ables for the repair) (04B, Consumables - Products),
-an aerosol spray brake cleaner (see Vehicle: Parts
and consumables for the repair) (04B, Consum-
ables - Products).
To use the injector cleaner, be sure to have a clean
brush in good condition (the brush must not lose any
bristles) as well as a clean container which has no im-
purities in it. WARNING
Do not clean the engine with a high pressure
cleaner to prevent damaging the connections.
Note:
There is no specific set of blanking plugs for S9U
and S9W engines. In order to comply with the
cleanliness recommendations, use plugs that are
compatible with the blanking plug sets for F9Q,
G9U, G9T or ZD3 engines.
Note:
Use a new injector cleaner each time work is car-
ried out (a used cleaning agent will contain impuri-
ties).

II - ADVICE TO BE FOLLOWED BEFORE ANY
OPERATION
1) Carry out the work in a clean working area and take
care to protect removed components from dust using
plastic bags which are hermetically-resealable, for ex-
ample.
2) Always order the following from the Parts Depart-
ment before carrying out work:
-a new set of blanking plugs, specific to the engine,
-enough lint-free cleaning cloths.
-one of the two cleaning products for fuel pipe
unions,
-the parts that are always to be replaced after each
removal operation, mentioned in the operational pro-
cedures specific to the vehicle (see related Workshop
Repair Manual).
3) Wear safety goggles fitted with side shields to pre-
vent the cleaning product from splashing the eyes.
4) Wear leaktight protective gloves (Nitrile type) to
avoid prolonged contact with the skin.
5) Before carrying out work on the injection system,
use plastic bags or clean rags, for example, to protect:
-the accessories and timing belts,
-the electrical accessories (starter, alternator, power-
assisted steering pump, sensors and electrical con-
nectors),
-the flywheel face.
III - INSTRUCTIONS TO BE FOLLOWED DURING
THE OPERATION
Wash your hands before and while carrying out the
work.
Replace leaktight protective gloves (Nitrile type) when
they are soiled or damaged.
All components removed from the injection system
must be stored in a hermetically sealed plastic bag
once they have been capped.
Reseal the bag hermetically, for example using adhe-
sive tape, even if the bag must be opened shortly after-
wards: ambient air can be a source of impurities.After opening the fuel circuit, the use of brushes, clean-
ing agents, air blow guns, rifle-type brushes or stan-
dard cloths is strictly prohibited: these items are likely
to allow impurities to enter the system.
When replacing a component with a new one or when
refitting it after storing it in a plastic bag, do not unpack
it until it is time to fit it on the vehicle.
IV - CLEANING
There are currently two procedures for cleaning the
fuel circuit before opening it in order to carry out work in
the workshop.
These procedures enable the fuel circuit to be cleaned
to prevent contamination from entering: they both have
the same end result and neither is preferred over the
other.
1 - Cleaning using injector cleaner
Clear the access to the unions that need opening, fol-
lowing the work procedures specific to the vehicle (see
the relevant Workshop Repair Manual).
Protect sections which are sensitive to fuel leaks.
Pour the injector cleaning agent into a container which
is free from impurities.
Dip a clean brush, which is not shedding bristles, into
the container of injector cleaning agent.
Clean the unions carefully using the brush and the in-
jector cleaning agent.
Blast the components that have been cleaned with
compressed air (tools, workbench, and also parts,
unions and around the injection system). Check that no
bristles from the brush have come away and that the
area is clean.
Wipe the sections that were cleaned with fresh clean-
ing cloths.
Open the circuit at the unions and immediately fit the
relevant blanking plugs. Note:
When using leather protective gloves, wear a pair of
leaktight protective gloves (Nitrile type) over the top.
IMPORTANT
Wear leaktight gloves (Nitrile type) for this opera-
tion.
IMPORTANT
Wear goggles with side protectors for this opera-
tion.

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-lubr icating.
