Remove the manifold mounting bolts and then remove the manifold.
REFITTING
IMPORTANT: note the rubber seal on the inlet tubes;
if necessary, seal this in its casing with some grease.
Bring all the cylinder head cover bolts into contact.
Tighten to 1.2 daN.m observing the tightening order
for the cylinder head cover bolts.
It is essential that you observe the order of tightening
and the torques recommended for refitting the
suspended mounting and the high pressure injection
section (see sections 13 and 19).
To refit, proceed in the reverse order to removal.

REMOVAL
Put the vehicle on a 2 post lift.
Disconnect the battery.
Bleed the engine cooling circuit and engine oil; do not
refit the oil drain plug.
Remove:
–the front right wheel,
–the right-hand wheel arch cover.
Remove the four mounting bolts of the coolant pump
cover.
Lock the crankshaft using a screwdriver in the starter
crown.
Remove the 30 hub lock nut from the coolant pump.Remove the coolant pump sprocket using the
U 14 L FACOM hub extractor
REFITTING
Replace the coolant pump.
WARNING: the rest of the coolant will drop into the
engine housing.
Ensure that the mating surface on the pump is clean
and that the coolant escapes from the engine housing
(oil change).
Refitting is the reverse of removal.

Suspended mountings
The right-hand suspended mounting is fitted with a
rear travel limiter linkage.
When removing the cover, linkage or cast iron
mounting attached to the cage, respect the tightening
procedure below which has been adapted for removed
parts.
Fit in the following order:
–the cast iron linkage mounting (1) on the shock
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
rubber pad (3) and fix to the linkage (2). Tighten the
linkage (2) mounting bolt (B) on the mounting (1) to
10.5 daN.m.Offer up the engine and tighten the cover mounting
bolts (D) on the engine to 6.2 daN.m.
Tighten the cover mounting bolt (E) on the rubber pad
(3) to 6.2 daN.m and the linkage connecting bolts (F)
on the cover (4) to 10.5 daN.m.

COOLING SYSTEM
Cooling system
Bleed the cooling circuit, the air conditioning circuit
(see special manual for air conditioning)
Open the relay unit at the top left of the ring and
disconnect the electric wiring harness from the cooling
system at the radiator.
Remove the front bumper, the radiator grille and the
radiator grille rack.
Remove the mounting bolts on the radiator
convergents and fold them to remove it from the
bottom.
Disconnect the air conditioning air hoses at the
compressor for the compressor/condenser connection
and at the quick-release union for the bottle/bulkhead
connection.
When removing/refitting the cooling system, it is
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).
REFITTING
Refitting is the reverse of removal.
Top up the coolant and the air conditioning circuit.
Replacement of the air conditioning condenser or the
cooling exchanger requires the removal of the cooling
system.

662AIR CONDITIONING
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.
REFITTING
Refitting is the reverse of removal.
