REMOVAL
I - REMOVAL PREPARATION OPERATION
aPosition the vehicle on a two-post lift (see Vehicle:
Towing and lifting) (02A, Lifting equipment).
aDisconnect the battery (see ) (80A, Battery).
aDrain the refrigerant circuit using a refrigerant
charging station (see Refrigerant circuit: Drain-
ing - Filling) (62A, Air conditioning).
aRemove:
-the front wheels (see Wheel: Removal - Refitting)
(35A, Wheels and tyres),
-the front wheel arch liners (see Front wheel arch
liner: Removal - Refitting) (55A, Exterior protec-
tion),
-the front bumper (see Front bumper: Removal -
Refitting) (55A, Exterior protection).
aDisconnect the pressostat connector (1) .
aRemove the plastic cover (2) from the condenser.
aUnscrew the condenser connecting pipe unions (3) . Special tooling required
Mot. 1448Remote operation pliers for
hose clips .
Equipment required
refrigerant charging station
safety strap(s)
IMPORTANT
When working in the engine compartment, take
care as the radiator fan(s) may start up unexpect-
edly (risk of being cut).
To avoid any risk of serious burns when the engine
is hot:
-do not open the expansion bottle cap,
-do not drain the cooling system,
-do not open the bleed screw(s).
WARNING
Before the operation, protect the electrical accesso-
ries to prevent any risk of shor t circuiting and pro-
tect the belts to avoid damaging them.
WARNING
When carr ying out a repair that requires a complete
change, it is essential to flush the circuit with clean
water, blast compressed air through the circuit to
drive out the water, fill and bleed the circuit and
then measure the effective protection.
The cr iteria to be met are:
-protection down to -25˚C ±± ± ±
2 for cold and temper-
ate countries,
-protection down to -40˚C ±± ± ±
2 for "extreme cold"
countries.
WARNING
The coolant helps to keep the engine running prop-
erly (heat exchange).
The system does not operate using pure water.AIR CONDITIONING
