COOLING
Engine cooling system: Specifications
D4F or D7F or K4M or K9K
19A
Vehicles in the current range have cooling systems
with the following basic specifications:
-hermetically-sealed pressurised circuit (with expan-
sion bottle valve),
-circuit using only type « D » fluid,
-passenger compartment heating system equipped
with a « heater matrix » type radiator located under
the dashboard which helps to cool the engine.
Coolant quantities
Special notes:
-protection down to - 25˚C ±± ± ±
2 for cold and temperate
countries,
-protection down to - 40˚C ±± ± ±
2 for "extreme cold" coun-
tries.

Expansion bottle cap valve rating:
I - CHECKING THE COOLING SYSTEM USING THE
TOOL (MOT. 1700)
a1 - Checking the expansion bottle cap valve
aUse the cooling system filling and diagnostic tool
(Mot. 1700). Consult the user's manual for this tool
(see Cooling system filling and diagnostic tool:
Use) (Technical Note 3857A, 19A, Cooling).
2 - Checking the sealing of the cooling circuit
aUse the cooling system filling and diagnostic tool
(Mot. 1700). Consult the user's manual for this tool
(see Cooling system filling and diagnostic tool:
Use) (Technical Note 3857A, 19A, Cooling).
II - CHECKING THE COOLING SYSTEM USING THE
TOOL (MS. 554-07)
a Special tooling required
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
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).
Note:
There are two procedures for checking the cooling
system:
-the procedure using the (Mot. 1700)
-the procedure using the (Ms. 554-07)
Expansion bottle cap with
...Valve rating
... a brown circle1.2 bar
... a yellow marking1.4 bar
... a white marking1.6 bar
... a grey marking1.8 bar
WARNING
If the coolant is leaking from the expansion bottle
cap, replace the valve.

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.
