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.

IMPORTANT
When working in the engine compartment, take
care as the radiator fan(s) may start up unexpect-
edly (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 drain the cooling system,
-do not open the bleed screw(s).
WARNING
Before the operation, protect the electrical accesso-
ries to prevent any risk of shor t circuiting and pro-
tect the belts to avoid damaging them.
WARNING
When carr ying out a repair that requires a complete
change, it is essential to flush the circuit with clean
water, blast compressed air through the circuit to
drive out the water, fill and bleed the circuit and
then measure the effective protection.
The cr iteria to be met are:
-protection down to -25˚C ±± ± ±
2 for cold and temper-
ate countries,
-protection down to -40˚C ±± ± ±
2 for "extreme cold"
countries.
WARNING
The coolant helps to keep the engine running prop-
erly (heat exchange).
