DISMOUNTIN G
Disconnect the battery.
Dismount :
- dashboard (see chapter 57 “dash-
board”);
- central console;
- electric windows control connectors;
- front pillars coverings;
- driving post cross beam;
- climate control box protector;
- gas purge vessel;
- climate control box gasket;
- engine air filter;
- climate control box central part from
the eight attachment screws;
- attachment screws of the climate c on-
trol unit and release the climate control blower
after disconnecting it.
- RACV attachment screws (1) on the
climate control box.
Clamp t he two hoses from the heating ra-
diator by means of the MOT 453 device.
Disconnect then the fast couplings from the
RACV heating radiator, recovering the c ool-
ing fluid. Dismou nt then:
- acoustic plate ( 2);
- mixing a nd distribution fl aps control
cables attached on RACV. Release RACV (3).
REMOU NT I NG
Perform the dismounting operations in the
reverse order. Fill up the cooling fluid and perform the cool-
ing circuit purging (see chapter 19 “ Filling –
Purging cooling circuit”).
Check :
- good operation of the flaps cables;
- good attachment of t he air ducts.
The require d tightening moment of t he
RACV attachment screws (1) on the climate
control box is of 0,6 daNm.

Disconnect the battery.
Dismoun
t the distributor of ventilation air con-
ditioning (RACV) position (2) by recovering the
cooling fluid (see R.A.C.V. Dismounting- Re-
mounting). Dismount the attachment screw of the heating
radiator (1 ) and after detaching from clips release
it.

fluid level after purging.
REMARK :
The self-adhesive gaskets (3), (4) and (5)
are to be obligatory replaced with new
ones.

AIR CONDITIONING
62 - 1
General
The purpose of the air conditioning unit is to produce a decrease of the tempera ture in t he
passengers compartment a nd to obt ain a l ower value tempera ture c ompare d to the e xterna l
environment one, reducing in the same time the air moisture.
MAINTENANCE
For a vehicle equipped with air conditioning, during the year it is recommended:-the checking of the refrigerant fluid filling;
- the cleaning and the air-blowing of the condenser and the cooling radiator fins;
- the checking of the condensation removal pipe on order not to be clogged.
For important leakage repair, for any components replacement (compressor, condenser, etc)
and if moisture was noticed in the air conditioning circuit, replace the dryer filter tank and drain
the unit; the same is valid also in case the conditioning circuit remains open without protection
covers more than 10 minutes.
IMPORTANT !
During winter, it is recommended the frequent start of the system, in order to prolong
the lifetime of t he compressor and of the whole system.
T he vehicle equipped with an air c onditioning system shall be not exposed for more
than 20 minutes i n painting c abin where there are temperatures higher than 80 °C.
It is obligatory the use of t he refrigerating agent and compressor oil type prescribed
by the manufacturer.
It is absolutely forbidden to perform welding works on the elements of the ai r condition
circ uits.
The fi lling of the air c onditioning system c an be pe rformed only by means of c harging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended piping protection in order to avoid t heir disconnection
by accident.
Avoid the drip of the oil compressor on the painted vehicle carriage body.
For component replacement implying t he circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.

SPECIAL TOOLS
MOT 453Hoses clamp
MOT 1202-01 Elastic clips pliers
The condenser is placed on the c ooling
radiator, ensuring the exhaust of the refrigerant
heat accumulated at compression.
DISMOUNTING
Disconnect the battery.
Drain the AC unit and recover t he oil and
the refrigerant fluid at the charging station.
Dismount the front grill.
Dismount the air filter inlet pipe.
Dismount the engine fan off the radiator.
Disconn ect the pipes from the condenser and
immediately close the disconnected pipes ends
and the condenser connections with protection
caps in order to avoid humidity and impurities
penetration in circuit.
Clamp the hoses from the radiator by means
of the MOT 453 device.
Di smount the hoses from the radiator by
means of the elastic clips pliers MOT 1202-01 ,
recovering the cooling fluid.
Dismount the radiator side attachment
supports on the radiator upper cross beam and
release the radiator together with the condenser.
Re l e a se t he condense r f rom t he four
attachment screws on the radiator.
REMOU NT I NG
Perform the dismounting operations in the
reverse order.
Tighten to t he required m oment the pipes
nut s .
- thread 3/4 “ 1,8 – 2,2 daNm
- thread 5/8 “ 1,0 – 1,4 daNm
Fill the AC unit with refrigerant fluid HFC
134a (0,600 Kg) by means of the charging unit.
Check for refrigerant fluid leaks.
Fill and purge the cooling circuit.
Check the good operation of the AC unit.
REMARK :
When mounting, line up the marks of
the hoses and mating parts .
