Note:
If the fuel filter is to be reused, fit blanking plugs
to the fuel supply pipes and fuel filter openings,
using the appropriate blanking plug kit, depend-
ing on the engine (see 13B, Diesel injection,
Diesel injection: Precautions for the repair,
page 13B-1) .
WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehi-
cle.
Note:
Chec k that the fuel filter is correctly positioned
and secure on its mounting by shaking it: the fil-
ter must not move.
WARNING
Prepare for the flow of fluid, and protect the sur-
rounding components.

I - CHECKING THE OPERATION OF THE FUEL
VAPOUR ABSORBER BLEED
aCheck the condition of the pipes to the tank.aCheck the condition of the pipes to the tank.
II - FUEL VAPOUR ABSORBER BLEED
CONDITIONS
aThe fuel vapour absorber bleed solenoid valve is
controlled by the computer.
During « on board diagnostic » fault finding, fuel va-
pour absorber bleeding is not authorised.
The opening cyclic ratio of the fuel vapour absorber
bleed solenoid valve can be viewed on the Diagnos-
tic tool by reading parameter « Fuel vapour absorb-
er bleed solenoid valve OCR » .
The solenoid valve is closed for a value below 1.2%. Equipment required
Diagnostic tool
Note:
Incorrect operation of the system may result in
rough idle or engine stalling.

a
I - DRAINING
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aRemove the expansion bottle cap.aRemove the engine undertray.
aPosition the coolant recovery tray under the vehi-
cle.
aRemove the cooling radiator bottom hose clip using
the tool (Mot. 1202-01) or (Mot. 1202-02) or (Mot.
1448).
aOpen the cooling system by removing the cooling ra-
diator bottom hose using the tool (Car. 1363).
aUse a compressed air nozzle to blow air into the
system through the expansion bottle opening to re-
move as much coolant as possible.
II - CLEANING
aFill the cooling system with water through the expan-
sion bottle.
aLet the water run until the water collected by the
cooling radiator bottom hose becomes clear.
aUse a compressed air nozzle to blow air into the
circuit through the expansion bottle opening to re-
move as much water as possible.
aRefit the hose which was removed.
III - FILLING
a
1 - Filling procedure with the tool (Mot. 1700)
aFill the cooling system with engine coolant recom-
mended by the manufacturer (see Vehicle: Parts
and consumables for the repair) (04B, Consum-
ables - Products) using the tool (Mot. 1700).
For the use of this tool (see Cooling system filling
and diagnostic tool: Use) (NT 3857A, 19A, Cool-
ing). Special tooling required
Mot. 1202-01Clip pliers for hose clips
(large size).
Mot. 1202-02Clip pliers for hose clips
(small size)
Mot. 1448Remote operation pliers for
hose clips .
Car. 1363Set of tr im removal levers.
Mot. 1700Fault finding and filling -
bleeding the cooling circuit.
Ms. 554-07Instr ument for testing the
cooling circuit and the expan-
sion bottle valve. Contains
caps 554-01, 554-04, 554-06
Equipment required
coolant recovery tray
compressed air nozzle
pedal press
IMPORTANT
When working in the engine compartment, take
care as the radiator fan(s) may start up unex-
pectedly (risk of being cut).
To avoid any risk of serious burns when the
engine is hot:
-do not open the expansion bottle cap,
-do not dr ain the cooling system,
-do not open the bleed screw(s).
WARNING
Before the operation, protect the electrical acces-
sories to prevent any risk of short circuiting and
protect the belts to avoid damaging them.
K4M
Note:
There are two procedures for filling the cooling
system:
-the method using the (Mot. 1700) tool is recom-
mended by Renault. It saves a considerable
amount of time because it does not require the
cooling system bleed screws to be opened,
-the procedure without a special tool.

2 - Filling method without special tools
a
aRemove the air filter unit (see 12A, Fuel mixture,
Air filter unit: Removal - Refitting, page 12A-13) .
aRemove the front engine cover.
aOpen the bleed screws (1) and (2) .
aFill the cooling system with engine coolant recom-
mended by the manufacturer (see Vehicle: Parts
and consumables for the repair) (04B, Consum-
ables - Products) via the expansion bottle until it
overflows.
aClose all the bleed screws as soon as the coolant
starts to flow in a continuous stream.aRefit the air filter unit (see 12A, Fuel mixture, Air fil-
ter unit: Removal - Refitting, page 12A-13) .
aRefit the engine cover.
aPressurise the system using the (Ms. 554-07) to
check that there are no leaks (see 19A, Cooling,
Engine cooling system: Check, page 19A-2) .
aRefit the expansion bottle cap.
aClean any surfaces soiled by the coolant.
IV - BLEEDING
a
aStart the engine.
aMaintain the engine speed at 2500 rpm using the
pedal press for 5 min.
aStabilise the engine speed at 2000 rpm until the fan
assembly has been activated twice.
aMaintain the engine speed at 2500 rpm, using the
pedal press for 5 minutes.
aStabilise the engine speed at 2000 rpm until the fan
assembly is activated.
aNote the coolant level in the expansion bottle after
this first activation.
aAccelerate at a minimum of 4000 rpm for several
seconds, until the level of coolant fluid in the expan-
sion bottle drops. WARNING
It is essential to open all of the bleed screws to
remove as much as air as possible in the cooling
system. Failure to perform this procedure may
prevent the cooling system from filling properly
and may damage the engine.
