aTop up the oil with the recommended type and vol-
ume of oil and refrigerant, depending on the work
carried out (see 62A, Air conditioning, Air condi-
tioning: Parts and consumables for the repair,
page 62A-2) .
aCheck there are no leaks using the electronic de-
tector (see 62A, Air conditioning, Refrigerant cir-
cuit: Check, page 62A-7) .
aCheck that the air conditioning system is operating
correctly (see 62A, Air conditioning, Air condi-
tioning: Check, page 62A-4) . WARNING
After injecting dye into the refrigerant, be sure to
indicate this on a label (supplied with the dye
capsule), and the date of the operation.
Position the label so it is visible near to the cold
loop filler valve.

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) .
aDrain the cooling system (see Cooling system:
Draining - Refilling) (19A, Cooling).
aDisconnect the battery (see ) (80A, Battery).
aRemove:
-the front wheels (see Wheel: Removal - Refitting)
(35A, Wheels and tyres),
-the front bumper (see Front bumper: Removal -
Refitting) (55A, Exterior protection),
-the radiator mounting cross member (see Radiator
mounting cross member: Removal - Refitting)
(41A, Front upper structure).
II - OPERATION FOR REMOVAL OF PART
CONCERNED
aRemove the cooling radiator (see Cooling radiator:
Removal - Refitting) (19A, Cooling). 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).
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
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.
WARNING
Consult the device's operating manual to avoid
incorrect use.D4F, and 780 – K9K – K4M
