Refitting) (80A, Battery).
- Remove:
- the engine undertray,
- the windscreen wiper arms (see Windscreen wiper
arm: Removal - Refitting) (85A, Wiping -
Washing),
- the scuttle panel half-grille (see Scuttle half-grille:
Removal - Refitting) (56A, Exterior equipment),
- the windscreen wiper mechanism (see Windscreen
wiper mechanism: Removal - Refitting)
(85A, Wiping - Washing),
- the scoop under the scuttle panel grille (see Scoop
under scuttle panel grille: Removal - Refitting)
(56A, Exterior equipment).
- Remove the nut (1) from the bulkhead insulation.
- Separate the bulkhead insulation.
II - OPERATION FOR REMOVAL OF PART
CONCERNED
- Remove:
- the bolt (2) of the pipe union,
- the pipe union (3) .
| WARNING
In order to avoid any refrigerant leaks, do not
damage (deform, twist, etc.) the pipe. |
- Disconnect the expansion valve - condenser connecting
pipe (4) from the expansion valve.
| WARNING
To prevent moisture from entering the system,
place plugs on the cold loop components which
are open to the air. |
- Fit plugs into the openings.
- Remove the bolt (5) from the pipe union.
- Disconnect the expansion valve - condenser connecting
pipe (6) from the condenser.
- Fit plugs into the openings.
- Unclip the expansion valve - condenser connecting
pipe at (7) .
- Unclip the expansion valve - condenser connecting
pipe at (8) .
M9R
- Remove:
- the bolt (9) ,
- the support (10) .
- Remove the expansion valve - condenser connecting
pipe.
REFITTING
I - REFITTING PREPARATION OPERATION
- Always replace the seals on the refrigerant fluid connecting
pipes.
- Lubricate the seals using recommended air conditioning
oil to make fitting easier.
II - REFITTING OPERATION FOR PART
CONCERNED
- Refit the expansion valve - condenser connecting pipe.
M9R
- Refit:
- the support (10) ,
- the support bolt.
- Clip:
- the expansion valve - condenser connecting pipe
at (8) ,
- the expansion valve - condenser connecting pipe
at (7) .
| WARNING
Do not remove the blanking plugs from each
component until the last moment.
Also, do not remove the components from their
packaging until they are to be fitted to the vehicle. |
- Remove the opening plugs on the side concerned.
| WARNING
To avoid any leaks, check that the pipe surface is
sound before positioning the new seal. The surface
must be clean and scratch free. |
- Fit new seals to the refrigerant connecting pipes.
- Connect the expansion valve - condenser connecting
pipe on the condenser.
- Refit the bolt of the pipe union.
- Torque tighten the bolt of the expansion valve -
condenser connecting pipe union on the condenser
(4 N.m).
- Remove the opening plugs on the side concerned.
- Connect the expansion valve - condenser connecting
pipe on the expansion valve.
- Refit:
- the pipe union,
- the bolt of the pipe union.
- Torque tighten the bolt of the pipe union on the
expansion valve (4 N.m).
III - FINAL OPERATION.
- Fit the bulkhead insulation in its original position.
- Refit:
- the nut of the bulkhead insulation,
- the scoop under the scuttle panel grille (see Scoop
under scuttle panel grille: Removal - Refitting)
(56A, Exterior equipment).
- the windscreen wiper mechanism (see Windscreen
wiper mechanism: Removal - Refitting)
(85A, Wiping - Washing),
- the scuttle panel half-grille (see Scuttle half-grille:
Removal - Refitting) (56A, Exterior accessories),
- the windscreen wiper arms (see Windscreen wiper
arm: Removal - Refitting) (85A, Wiping -
Washing).
- Connect the battery (see Battery : Removal - Refitting)
(80A, Battery).
| Note:
When replacing a pipe, add 10 ml of the recommended
oil to the quantity of oil recovered. |
- Fill the refrigerant circuit using the refrigerant charging
station (see 62A, Air conditioning, Coolant
circuit Draining - Refilling, page 62A-11)
- Set the control of the passenger compartment
blower unit to the maximum speed.
- Check that the air conditioning system is operating
correctly (see 62A, Air conditioning, Air conditioning:
Check, page 62A-6) .
- Check for leaks (see 62A, Air conditioning, Coolant
circuit check, page 62A-9) .
