move as much coolant as possible.
II - CLEANING
a Fill the cooling system with water through the expan-
sion bottle.
a Let the water run until the water collected from the
cooling radiator bottom hose becomes clear.
a Use a compressed air nozzle to blow air into the

move as much coolant as possible.
a Refit the cooling radiator bottom hose.

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 filling the cooling
system:
- the method using the tool, is recommended 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.
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.
