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 Battery: Removal - Re-
fitting) (80A, Battery).
aDrain the air conditioning circuit using a refrigerant
charging station (see Refrigerant circuit: Drain-
ing - Filling) (62A, Air conditioning).
aRemove:
-the engine undertray bolts,
-the engine undertray,
-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).
aDrain the cooling system (see 19A, Cooling, Cool-
ing system: Draining - Refilling, page 19A-9) . Special tooling required

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
Prepare for the flow of fluid, and protect the sur-
rounding components.
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.
