Repair.
Respect the precautions to be taken prior to any operation:
- The front flexible pipe must be protected against any external mechanical damage.
- The front flexible pipe must not come into contact with corrosive products.
- Do not deform the front flexible pipe more than 20°angular (X), 20 mm axial, 25 mm shearing
(Y)(front flexible pipe removed).
- Do not deform the front flexible pipe more than 3°angular (X), 0 mm axial, 3 mm shearing (Y)
(front flexible pipe in place).
WARNING: Non-respect of these precautions will shorten the life of the flexible pipe.
It is therefore imperative to disconnect or remove the exhaust line for any operations
necessitating lifting of the engine-gearbox.

DRAINING, FILLING AND BLEEDING THE ENGINE COOLING CIRCUIT
Open the plug (3)to drain the second bank of cylinders.
Remove the drain plugs (2)and (3).
Filling and bleeding the circuit.
Prior to any filling, rinse the cooling with fresh water.
WARNING: Check the sealing of the cooling circuit.
Open the bleed screws of the following components:
- Heater matrix outlet.
- Coolant outlet housing.
- Radiator.
Close the drain screw (1)of the radiator.
Refit the plugs (2)and (3)with a new seal ; tighten to3 ± 0,3 m.daN.
Fit the filling cylinder assembly [1], [3], and [2]on the filler aperture.
Fill the cooling circuit.
NOTE:Keep the filling cylinder full to the maximum.

SAFETY REQUIREMENTS: HDi DIRECT INJECTION SYSTEM
Safety requirements.
Preamble.
All interventions on the injection system must be carried out to conform
with the following requirements and regulations:
- Competent health authorities.
- Accident prevention.
- Environmental protection.
WARNING: Repairs must be carried out by specialised personnel
informed of the safety requirements and of the precautions to be
taken.
Safety requirements.
IMPERATIVE: Take into account the very high pressures in the high
pressure fuel circuit (1600 bars), and respect the requirements
below:
- No smoking in proximity to the high pressure circuit when work is being
carried out.
- Avoid working close to flame or sparks.
Engine running:
- Do not work on the high pressure fuel circuit.
- Always stay clear of the trajectory of any possible jet of fuel, which could
cause serious injuries.
- Do not place your hand close to any leak in the high pressure fuel circuit.After the engine has stopped, wait 30 secondsbefore any intervention.
NOTE:This waiting time is necessary in order to allow the high pressure
fuel circuit to return to atmospheric pressure.
Cleanliness requirements.
Preliminary operations.
IMPERATIVE: The technician should wear clean overall.
Before working on the injection system, it may be necessary to
clean the apertures of the following sensitive componen (refer to
corresponding procedures):
- Fuel filter.
- Fuel high pressure pump.
- Fuel high pressure common injection rail.
- Fuel high pressure pipes
- Diesel injector carriers.
IMPERATIVE: After dismantling, immediately block the apertures of
sensitive components with plugs, to avoid the entry of impurities.
Work area:
- The work area must be clean and free of clutter.
- Components being worked on must be protected from dust.

Checks.
IMPERATIVE : Respect the safety and cleanliness requirements specific to high pressure
diesel injection (HDi) engines.
Connect the tool [1]between the booster pump and the fuel filter (white mark on the fuel supply
pipe).
Connect the tool [2]downstream of the diesel injectors, between the high pressure fuel pump and
the fuel filter green mark on the fuel return pipe.
Connect the tool [3]on tool [1]or on tool [2].
WARNING: Any check of pressure downstream of the fuel filter is prohibited.
NOTE:To check the pressures while the vehicle is being driven, insert the extension [4] between
tool [3]and tools [1]or [2].
