a
aRemove the air filter unit (see 12A, Fuel mixture,
Air filter unit: Removal - Refitting, page 12A-13) .
aRemove the front engine cover.
aOpen the bleed screws (1) and (2) .
aFill the cooling system with engine coolant recom-
mended by the manufacturer (see Vehicle: Parts
and consumables for the repair) (04B, Consum-
ables - Products) via the expansion bottle until it
overflows.
aClose all the bleed screws as soon as the coolant
starts to flow in a continuous stream.aRefit the air filter unit (see 12A, Fuel mixture, Air fil-
ter unit: Removal - Refitting, page 12A-13) .
aRefit the engine cover.
aPressurise the system using the (Ms. 554-07) to
check that there are no leaks (see 19A, Cooling,
Engine cooling system: Check, page 19A-2) .
aRefit the expansion bottle cap.
aClean any surfaces soiled by the coolant.
IV - BLEEDING
a
aStart the engine.
aMaintain the engine speed at 2500 rpm using the
pedal press for 5 min.
aStabilise the engine speed at 2000 rpm until the fan
assembly has been activated twice.
aMaintain the engine speed at 2500 rpm, using the
pedal press for 5 minutes.
aStabilise the engine speed at 2000 rpm until the fan
assembly is activated.
aNote the coolant level in the expansion bottle after
this first activation.
aAccelerate at a minimum of 4000 rpm for several
seconds, until the level of coolant fluid in the expan-
sion bottle drops. 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.

3 times approximately every 2 minutes until the fan
assembly starts for the second time.
aMaintain the engine speed at 3000 rpm using a ped-
al press, until the fan assembly has been activated
for a third time.
aCheck that the heating is operating correctly.
aAllow the engine to cool until the engine coolant tem-
perature is less than 50˚C.
