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.

aComplete the cleaning of the parts using an abrasive
pad.
aDegrease the joint faces with SURFACE CLEANER
(see Vehicle: Parts and consumables for the re-
pair) (MR 411, 04B, Consumables - Products).
II - REFITTING OPERATION FOR PART

-the engine tie-bar (see 19D, Engine mounting,
Lower engine tie-bar: Removal - Refitting, page
19D-18) , WARNING
Do not scrape the joint faces of the aluminium,
any damage caused to the joint face will result in
a risk of leaks.
IMPORTANT
Wear latex gloves during the operation.
WARNING
The joint faces must be clean, dr y and free from
grease (avoid finger marks).

WARNING
Applying excess sealant could cause it to be
squeezed out when parts are tightened. A mix-
ture of sealant and fluid could damage certain
components (engine, radiator, etc.).
WARNING
Failure to observe the following procedure may
cause irreparable damage to the water pump
bearing.
Note:
To fit the pump on the two pins of the cylinder
block, never apply pressure to the water pump
pinion; instead use the pump mounting bolts by
pre-tightening them.
