Checking the setting of the valve timing.
Peg :
- The engine flywheel, using tool [3]. (From under the vehicle).
- The camshaft, using tool [5].
WARNING :On removing screws (6), (7), (9), and (5) of the timing cover, refit the
screw(5) equipped with a spacer (thickness :17 mm).
Tighten to 1,5 ± 0,1m.daN.
(The screw (5)is one of the screws fixing and sealing the water pump).
WARNING : Should it be impossible to peg the camshaft, check that the offset
between the camshaft pinion hole and the pegging hole is not more than 1 mm,
with the help of a mirror «a» and a Ø 7 mm screw.

Checking the setting of the valve timing (continued).
IMPERATIVE : If it is impossible to line up the marks on the chain and on the camshaft drive
pinions, restart the camshaft setting.
(See operation for removing and refitting camshafts).
- If the marks on the chains and pinions are coinciding, continue the checking operations.
Peg :
- The crankshaft, using tool [3].
- The camshaft pinion, using tool [5]
IMPERATIVE : Should it be impossible to peg the camshaft, check that the offset between the
camshaft pinion hole and the pegging hole is not more than 1 mm (use a screw 7 mm in dia.).
If the offset is more than 1 mm, restart the setting of the valve timing
(See corresponding operation).
- Remove the tools [3] and [5].

FILLING AND BLEEDING THE COOLING CIRCUIT
TOOLS
[1] Filling cylinder: 4520-T
[2]Adaptor for filling cylinder: 4222-T.
ESSENTIAL : Respect the safety and cleanliness recommendations.
- The draining and refilling operations can be carried out by means of a WINN’S coolant replacement
apparatus or similar; it is essential to follow the instructions when using this apparatus.
Filling and bleeding
- Fit the cylinder adaptor [2] 4222-Tand the filling cylinder [1] 4520 -T.
- Use the coolant to ensure protection between - 15°Cand - 37°C.
- Slowly fill the system.
NOTE :Keep the cylinder filled up (visible level).
- Close each bleed screw as soon as the coolant flows without air bubbles.
- Start the engine : Engine speed 1500 rpm.
- Maintain this speed until the third cooling cycle (cooling fans have cut in and cut out).
- Stop the engine and allow it to cool down.
- Remove the filling cylinder [1] 4520-T and the adaptor [2] 4222-T.
- Top up the system to the maximum mark, with the engine cold.
- Refit the filler cap.
