REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aDrain the coolant circuit using the refrigerant
charging station.
aDisconnect the battery (see Battery: Removal - Re-
fitting) (80A, Battery).
aRemove the front bumper (see Front bumper as-
sembly: Exploded view) and (see Exterior body
front trim assembly: Exploded view) (55A, Exteri-
or protection).aRemove:
-the air deflector mountings (1) ,
-the air deflector (2) .
aRemove the intercooler (see ) (12B, Turbocharging).
II - REMOVAL OPERATION
aRemove the bolts from the pipes on the condenser
(see 62A, Air conditioning, Air conditioning: List
and location of components, page 62A-1) .
aDisconnect the pipes from the condenser (see 62A,
Air conditioning, Air conditioning: List and loca-
tion of components, page 62A-1) .
aFit blanking plugs on the pipe openings.
aRemove (see 62A, Air conditioning, Air conditio-
ning: List and location of components, page
62A-1) :
-the condenser bolts,
-the condenser. Equipment required
refrigerant charging station
IMPORTANT
To avoid all risk of damage to the systems, apply
the safety and cleanliness instructions and opera-
tion recommendations before carrying out any
repair (see Air conditioning: Precautions for the
repair) .
WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which are
open to the air.
Note:
Use blanking plugs for the fuel circuits with part
numbers 77 01 208 229 or 77 01 476 857 to plug
any openings exposed to the open air. They must
be clean. Do not use any which have already been
used to plug a fuel circuit.
WARNING
Consult the device's operating manual to avoid
incorrect use.

REFITTING
I - REFITTING PREPARATION OPERATION
a
aCheck, and if necessary replace, the refrigerant cir-
cuit pipe seal.
aClean the surface and the seal of the pipe using EN-
GINE CLEANER (see Vehicle: Parts and con-
sumables for the repair) (04B, Consumables -
Products).aUse a compressed air gun to blow the surface and
the seal of the connecting pipe.
aLubricate the surface of the connecting pipe and the
seal with air conditioning oil (see 62A, Air condi-
tioning, Air conditioning: Parts and consum-
ables for the repair, page 62A-9) .
aRemove the blanking plugs.
II - REFITTING OPERATION
aProceed in the reverse order to removal.
aConsult the refrigerant and oil quantity values before
filling the circuit (see 62A, Air conditioning, Air
conditioning: Parts and consumables for the re-
pair, page 62A-9) .
aFill the refrigerant circuit using the refrigerant
charging station (see Refrigerant circuit: Drain-
ing - Filling) .
aCheck that the air conditioning system is operating
correctly (see Air conditioning: Check) .
aCheck for leaks (see Refrigerant circuit: Check) . WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehi-
cle.
