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.

COOLING
Engine cooling system: Check

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)

WARNING
If the coolant is leaking from the expansion bottle
cap, replace the valve.
