TOP AND FRONT OF ENGINE
Timing belt
11 E7J - K7M ENGINE
REFITTING
There is an arrow on the back of the belt showing
the direction of rotation and two marks for adjus-
tment.
Align the reference marks (marks N) on the belt
with those on the sprockets ( L ) and the casings
( M ).
Ensure the belt is fitted in the correct direction
and begin positioning it on the crankshaft
sprocket.
By moving the tensioner using tool Mot. 1135-01,
tighten the belt until the fitting tension is obtai-
ned (see section 07 Timing belt tension ).
Tighten tensioner nut ( O ) to 5 daN.m.
It is vital to tighten the tensioner nut to 5 daN. m
to avoid any loosening of the tensioner which
could damage the engine.
Refitting is the reverse of removal.
NOTE
- To refit the crankshaft pulley, tighten the
crankshaft pulley bolt to 2 daN.m plus an angle
of 68° ± 6°.
- To tension the accessories belt (see section 07
accessories belt tension).

REMOVAL
Put the vehicle on a 2 post lift.
Disconnect the battery.
Remove:
- the computer and its mounting,
- the accessories belt in the following manner:
Slacken the tensioner (4) by the central bolt,
using a 7 mm allen key, by a quarter turn (cut
the end of the tool to approximately 12 mm)
while holding the outer nut with a 22 mm open
wrench.
Slackening the tensioner using the 22 mm wrench
automatically damages the adjustment teeth,
destroying the air conditioning and/or power as-
sisted steering mounting.
