absorber cage and tighten the bolts (A) to 3 daN.m,
–the linkage (2) on the mounting (1) without tightening
it,
–the rubber pad (3) on the cage and tighten the bolts
(C) by 5 to 6.5 daN.m,
–the suspended engine mounting cover (4) on the

recommended that you do not disconnect the
connections between the high pressure pipes and the
condenser/bottle unit as the seals are special and
delicate to replace.Set the radiator cross member on a table with shims
and release the mountings.
Remove the two mounting bolts from the cross
member on the tips of the side members.
Lift the vehicle while holding the cooling system to
prevent damage (operation for two people).

Air conditioning compressor
The G9T engine vehicle is fitted with a variable
geometry air conditioning compressor; that is, the
compressor adapts the flow of refrigerant fluid
according to a difference in pressure between the
compressor inlet and outlet, and not according to the
temperature read by the sensor (omission of the
evaporator sensor).
The system cannot be adjusted
The pressure relief valve is still present but calibrated
differently.
REMOVAL
Put the vehicle on a 2 post lift.
Disconnect the battery.
Drain the refrigerant circuit (see special "AIR
CONDITIONING" manual).
Remove:
–the front right wheel,
–the right-hand wheel arch cover,
–the lower engine cover,
–the air exchanger/throttle body unit pipe after
disconnecting it,.
–the accessories belt (see methods in section 07
"Accessories belt"),Unscrew the two mounting clamps on the compressor
refrigerant pipes and carefully plug the openings.
Unscrew the four mounting bolts from the air
conditioning compressor and remove it.
