REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aDrain the refrigerant circuit using a refrigerant
charging station (see 62A, Air conditioning, Re-
frigerant circuit: Draining - Filling, page 62A-8) .
aDisconnect the battery (see ) (80A, Battery).
aRemove:
-the wiper arms (see Windscreen wiper arm: Re-
moval - Refitting) (85A, Wiping - Washing),
-the scuttle panel grille (see Scuttle panel grille:
Removal - Refitting) (56A, Exterior equipment),
-the scoop under the scuttle panel grille (see Scoop
under the scuttle panel grille: Removal - Refit-
ting) (56A, Exterior equipment). Special tooling required
Mot. 1410Set of refrigerant pipe union
disconnection sockets.
(dimensions in inches): 5/16,
3/8, 1/2, 5/8, 3/4, 7/8.
Equipment required
refrigerant charging station
compressed air nozzle
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 62A, Air conditioning, Air conditioning:
Precautions for the repair, page 62A-1) ,
- (see Vehicle: Precautions for the repair) (01D,
Mechanical introduction).
WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which are
open to the air.
WARNING
In order to avoid any refrigerant leaks, do not dam-
age (deform, twist, etc.) the pipe.
Note:
Use blanking plugs for the fuel circuits with part
numbers 77 01 2008 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
To prevent the surrounding components from over-
heating, do not damage (tear, pierce, bend, etc.) a
heat shield.
Any damaged heat shields must be replaced.
Note:
The « expansion valve - intermediate pipe » and
« expansion valve - dehydrator reservoir » connect-
ing pipes cannot be separated.
WARNING
Consult the device's operating manual to avoid
incorrect use.
