Remove the suspended engine mounting.
Remove the timing cover, water pump cover and
suspended engine mounting cover on the cylinder
head .
Turn the engine in the operating direction until
the timing reaches its setting point (the camshaft
and crankshaft markings are aligned), whilst in-
serting pin Mot. 1054 into the flywheel.

Tighten the tension wheel nut.
Turn the engine at least twice (never in the op-
posite direction to normal operation).
Insert the pin in the engine at TDC, then remove
the pin .
Check that the timing is correct on the crankshaft
and camshaft side.
Slacken the tension wheel nut and turn it slightly
clockwise using tool Mot. 1135-01 until the two
holes of the tension wheel are lined up
horizontally.
Retighten the tension wheel nut.
b)Turn the engine at least twice (never in the
opposite direction to normal operation).
Insert the pin in the engine at
TDC then re-
move the pin.
Using tool Mot. 1386, apply a pretensioning
torque of 1 daN.m between the crankshaft
sprocket and the water pump.
Fit tool Mot. 1273 and note the tension measure-
ment, which should be 20±
3 US (fitting tension),
or simply adjust by varying the position of the
tension wheel using Mot. 1135-01 and repeat the
tensioning process in (b).
Tighten the tension wheel nut to a torque of
5 daN.m.
IMPORTANT
Following each variation of the tension wheel
position, turn the engine at least twice before
proceeding to measure the tension .
Apply the pretensioning of 1 daN.m which allows
all belt play to be eliminated.
Refitting is the reverse of removal.
Fit the suspended engine mounting .

This test can only be carried out using a lead testing kit supplied by NAUDER.
To obtain a testing kit, contact your local After Sales Head Office.
Part numbers : - Complete kit : T900
- 40 test papers : T900/1
ANTIPOLLUTION
Test for the presence of lead
14
METHOD
a - Test conditions :
- Engine stationary.
- Exhaust pipes warm.
- Do not test when the temperature is below 0°C.
b- If necessary use a soft cloth to clean the inside of the exhaust pipe so any soot deposits are removed.
c- Wearing the gloves, take a test paper and moisten it slightly with distilled water (the paper is not
effective if it is too wet).
d- Press the damp paper onto the cleaned exhaust pipe immediately and hold it there firmly for about a
minute.
e- Remove the test paper and allow to dry. The test paper will turn red or pink if lead is present.
IMPORTANT: The test for lead should only be carried out on the exhaust pipe, never on the oxygen
sensor.

COOLING
Filling and bleeding
19
There is no heater matrix water control valve.
Water flow is continuous in the heater matrix,
which contributes to the cooling of the engine.
FILLING
Check the tightening of the drain plug(s).
Open the two bleed screws.
Fill the circuit through the opening in the expan-
sion bottle.
Tighten the bleed screws as soon as the liquid
flows in a continuous jet.
Start the engine (2 500 rpm).
Adjust the level by overflow for a period of about
4 minutes .
Close the bottle.
BLEEDING
Allow the engine to run for about 10 minutes at
2 500 rpm, until the fan(s) operate (time necessary
for automatic degassing).
Check the liquid level is at the "Maximum" mar-
ker.
DO NOT OPEN THE BLEED SCREWS WHILST THE
ENGINE IS TURNING.
RE-TIGHTEN THE EXPANSION BOTTLE CAP WHILST
THE ENGINE IS WARM.
