– the earth strap on the bulkhead,
– the mountings of the air conditioning hoses (if
fitted) on the compressor and the condenser.
NOTE: it is essential to insert plugs in the pipes and on
the compressor to prevent the moisture entering the
circuit.
Remove the upper radiator mountings and attach the
cooling system to the engine.
Fit the engine retaining tool Mot. 1453 ensuring that
the strap is correctly positioned.
Remove the suspended engine mounting cover.Insert a wooden block between the gearbox and the
sub-frame.
Remove the nut (1), then tap it with a copper hammer
to release the suspended engine mounting stud.
Fit tool Mot. 1159 as shown below.

Special features of vehicles fitted with air
conditioning:
Before removing the accessories belt, check the
centreline of the automatic tensioner (see
section 07 "Checking the accessories belt
tension").
Loosen bolt (A), then bolt (B) to past the shoulder
while holding the automatic tensioner plate using a
9.35 mm square, then relax the belt moving the
ratchet in the direction of the arrow.
Remove the Top Dead Centre pin plug.
Position the engine support, tool Mot. 1453 with the
retaining straps.Remove:
– the suspended mounting cover and its movement
limiter.
– the bolt (1), and slacken engine tie-bar bolt (2),
without removing it.
Adjusting the timing
Turn the crankshaft to align the camshaft and housing
timing marks while at the same time inserting the TDC
pin Mot. 1054 (begin to press one half tooth on the
pin before aligning the camshaft marks to prevent
it falling into a crankshaft balancing hole).

Fit the reading head of Mot. 1505 and carry out the
measurement, then adjust the tension using the bolt
in contact with the belt until pretension value
T1 = 68 ± 3 Hertz is reached.
Tighten the tensioner.
Turn the crankshaft four times and reposition the
timing at top dead centre using the pin.
Remove pin Mot. 1054.
Apply a pretensioning torque using Mot. 1543 (fitted
with cover N˚ 3) by using a torque wrench adjusted to
a torque of 1.1 daN.m on the edge of the belt to be
measured.
Fit the reading head of Mot. 1505 and carry out the
measurement, then adjust the tension using the bolt
in contact with the belt until pretension value
T2 = 61 ± 5 Hertz is reached.
Tighten the tension wheel nut to a torque of 5 daN.m.
NOTE: it is vital that you tighten the tension wheel
nut to torque to avoid any slackening which may
cause damage to the engine.
Never refit a belt once removed, but replace it.
Replace the crankshaft pulley bolt and tighten it to a
torque of 2 daN.m plus an angle of 115˚ ± 15˚.
See section 07 "Accessories belt tension" for the
tension value for fitting the power assisted steering
belt.The belts on vehicles fitted with air conditioning are
tensioned by bringing the automatic tensioner plate to
a stop at bolt (B), without forcing it, using a 9.35 mm
square.

Cleanliness
CLEANLINESS INSTRUCTIONS WHICH MUST BE FOLLOWED WHEN WORKING ON THE HIGH PRESSURE
DIRECT INJECTION SYSTEM
Risks relating to contamination
The system is very sensitive to contamination. The risks caused by the introduction of pollution are:
– damage to or destruction of the high pressure injection system,
– seizing of a component or a component which is not sealed.
All after-sales operations must be performed under very good cleanliness conditions. This means that no impurities
(particles a few microns in size) have penetrated into the system during removal or into the circuits via the fuel
unions.
The cleanliness principle must be applied from the filter to the injectors.
WHAT ARE THE POLLUTING ELEMENTS?
The elements which pollute are:
– metal or plastic splinters,
– paint,
– fibres:
!of cardboard,
!of brushes,
!of paper,
!of clothing,
!of cloths.
– foreign bodies such as hair,
– ambient air,
– etc.
WARNING: it is impossible to clean the engine using a high pressure washer at the risk of damaging connections.
Also the moisture may collect in the connectors and cause electrical connection problems.
INSTRUCTIONS TO BE FOLLOWED BEFORE
ANY WORK IS CARRIED OUT ON THE INJECTION SYSTEM
!Ensure that you have plugs for the unions to be opened (bag of plugs sold by the Parts Department).
Plugs are to be used once only. After use, they must be thrown away (once used they are soiled and cleaning is
not sufficient to make them reusable).
Unused plugs must be thrown away.
!Ensure that you have the resealable plastic bags for storing removed parts. There is less risk of parts stored in this
way being subjected to impurities. The bags can be used only once, and once used they must be thrown away.
!Ensure that lint-free cleaning wipes are available (cloths with SODICAM part numbers). The use of conventional
cloth or paper is prohibited. In fact, these create lint and may contaminate the system's fuel circuit. A lint-free
cloth should only be used once.

INSTRUCTIONS TO BE FOLLOWED BEFORE OPENING THE FUEL CIRCUIT
!For each operation, use new thinner (used thinner contains impurities). Pour it into a clean receptacle.
!For each operation, use a clean brush which is in good condition (the brush must not shed its bristles).
!Clean using the unions to be opened and the parts to be removed using thinner and tweezers.
!Blow compressed air over the cleaned parts (tools, set up the same way as the parts, connections and injection
system zone). Check that no bristles are left.
!Wash your hands before and during the operation if necessary.
!When using protective gloves, cover leather gloves with latex gloves (available from SODICAM).
INSTRUCTIONS TO BE FOLLOWED DURING THE OPERA
TION
!As soon as the circuit is open, all openings must be blanked to prevent pollution from penetrating the circuit. The
plugs to be used are available from the Parts Department. They must not be reused.
!Reseal the bag hermetically, even if it has to be reopened only a short time later. Ambient air carries pollution.
!All components of the injection system must, after having been blanked, be stored in a hermetically sealed plastic
bag.
!After opening the circuit, the use of a brush, thinner, bellows, sponge or normal cloth is strictly forbidden. In fact,
these elements are liable to cause the entry of impurities into the system.
!When replacing a component with a new one, do not remove it from its packaging until it is to be fitted to the vehicle.
