–the pulley; remove the nut and take the pulley out
without removing the stud.
REFITTING
Fit:
–the pulley,
–the automatic tension wheel without tightening it and
position the groove (7) of the tension wheel correctly
in the pin,
–the three bolts at the centre of the inlet camshaft
sprocket holes (this must be free),
–the exhaust camshaft timing tool Mot. 1537.
Check that the crankshaft is at top dead centre.
Fit the timing belt at the same time as the exhaust
camshaft sprocket, and position the sprocket mounting
bolts at the centre of the holes.
Operation of the exhaust camshaft timing/locking tool
repeater: mobile mark (1) on the tension wheel pushes
the repeater (2) to the lower section (3). The upper
section has two edges (4) and (5) which, repeat the
position of the tension wheel index by aligning with the
edge (6) of the fixed section of the tool.Adjust the position of the tension wheel (by pivoting
the tension wheel eccentric anticlockwise) plus
approximately 5˚ by aligning sections (5) and (6).

1 daN.m.
Remove the camshaft timing tools Mot. 1534 and
Mot. 1537 and the TDC pin Mot. 1536.
Rotate the crankshaft through two revolutions in a
clockwise direction (timing side).
Pin the crankshaft to top dead centre (the top dead
centre mark on the crankshaft accessories pulley must
be in the vertical axis of the engine).
Fit the camshaft timing tools Mot. 1534 and
Mot. 1537.
Check that the tab of Mot. 1537 moves vertically
without constraint.
Undo the camshaft timing sprocket bolts by a
maximum of one turn. Checking the timing and the tension
Undo the tension wheel bolt (8) while holding the
eccentric with a 6 mm Allen key.
Pivot the tension wheel eccentric clockwise, until the
surface (10) of the tab (11) is aligned with the
upper surface (12) of tool 1537.

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.
