AIR CONDITIONING

62- 10

DISMOUNTING
Disconnect the battery.
Drain the air condiotioning unit to the station

by recovering the refrigerant fluid

Dismount it from screws (6) and release the

cold air-blowing device (2) from the climate con-
trol box (see D.S.A.F. dismounting-remounting)

Disconnect and release the two attachment

screws (3) of the air blower.

Dismount the resistance’s assembly (7)
Supply the gear motor in order to bring the

recycling control flap in vertical position.

Dismount the attachment screw (1) of the air

filter protection cap (9) and release the filter (8).

Dismount the attachment screws (4) of the

D.S.A.F. cases and release the evaporator (5).

REMOUNTING

Perform the dismounting operations in the

reverse order.

Vacuum then charge the air conditioning

circuit with refrigerant fluid HFc 134a by
means of the charging station.

Check the good operation of the air

conditioning system.

Compressor

FUNCTION

The compressor is suction the vapors com-

ing from evaporator at low temperature and
pressure, compress them and transmit the gas
at high temperature and pressure towards con-
denser.

The refrigerant fluid in entering in condenser

in vapors condition, at high temperature and
pressure, where, by condensing, is transmitting
in the external environment the abstracted heat.

At condenser exit, the refrigerant fluid is in

liquid condition, at high pressure and tempera-
ture.

DISMOUNTING

Drain the refrigerant circuit to a charging

station.

Disconnect the battery.
Disconnect the supply wiring connector of

the compressor clutch.

Dismount the screw of attachment clamp

of the refrigerant pipes on compressor.

Cover the open piping with protectors.

Dismount the compressor-driving belt.
Dismount the four compressor attachment

screws.

Extract the compressor.

REMOUNTING

In case compressor is replaced, this one is

delivered filled with oil.

Position the compressor with the filling cap

upwards.

Mount the compressor attachment screws.
Tighten the compressor attachment screws

to the required moment of 2,1 daNm.

Remount the two refrigerant pipes and

tighten the attachment clamp screw to the re-
quired moment of 1,2 daNm.

Mount the compressor-driving belt and ten-

sion it by acting upon the screw (1) according
to the method described in chapter 07 “ Ac-
cessories belts tensioning”.

The tensioning values are :
150 - 155 Hz - compressor belt;
214 – 230 Hz – DA pump/compressor belt.
Connect the supply wire connector of the

compressor clutch.

Vacuum and fill the circuit with refrigerant

fluid HFC 134a, by means of the charging sta-
tion (see chapter 62 “Draining – Filling unit
refrigerant circuit”).

REMARK :
Before mounting check the condition

of the gaskets and lubricate them with
compressor oil PAG SP 10.

Condenser

SPECIAL TOOLS
MOT 453

Hoses clamp

MOT 1202-01

Elastic clips pliers

The condenser is placed on the cooling

radiator, ensuring the exhaust of the refrigerant
heat accumulated at compression.

DISMOUNTING

Disconnect the battery.
Drain the AC unit and recover the 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.
Disconnect 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.

Dismount 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.

Release the condenser from the four

attachment screws on the radiator.

REMOUNTING

Perform the dismounting operations in the

reverse order.

Tighten to the required moment the pipes

nuts.

- 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.
