Filling and bleeding
There is continuous circulation in the heater matrices.
FILLING
It is essential to open the two bleed screws at the
top of the radiator and the cylinder head coolant
pipe housing outlet.
Fill the circuit through the expansion bottle opening.
Close the bleed screws as soon as the liquid starts to
flow in a continuous stream.
Start the engine (2 500 rpm).
Adjust the level by overflow for a period of about
4 minutes.
Close the bottle.
BLEEDING
Allow the engine to run for about 20 minutes at
2 500 rpm, until the engine fans(s) operate (time
necessary for automatic degassing).
Check the liquid level is at the "Maximum" marker.
DO NOT OPEN THE BLEED SCREWS WHILST THE
ENGINE IS RUNNING.
REFIT THE EXPANSION BOTTLE CAP WHILE THE
ENGINE IS WARM.

COOLING SYSTEM
Cooling system
Bleed the cooling circuit, the air conditioning circuit
(see special manual for air conditioning)
Open the relay unit at the top left of the ring and
disconnect the electric wiring harness from the cooling
system at the radiator.
Remove the front bumper, the radiator grille and the
radiator grille rack.
Remove the mounting bolts on the radiator
convergents and fold them to remove it from the
bottom.
Disconnect the air conditioning air hoses at the
compressor for the compressor/condenser connection
and at the quick-release union for the bottle/bulkhead
connection.
When removing/refitting the cooling system, it is
recommended that you do not disconnect the
connections between the high pressure pipes and the
condenser/bottle unit as the seals are special and
delicate to replace.Set the radiator cross member on a table with shims
and release the mountings.
Remove the two mounting bolts from the cross
member on the tips of the side members.
Lift the vehicle while holding the cooling system to
prevent damage (operation for two people).
REFITTING
Refitting is the reverse of removal.
Top up the coolant and the air conditioning circuit.
Replacement of the air conditioning condenser or the
cooling exchanger requires the removal of the cooling
system.
