Tightening the cylinder head
METHOD FOR TIGHTENING THE CYLINDER HEAD
REMINDER: in order to tighten the bolts correctly, use
a syringe to remove any oil which may have entered
the cylinder head mounting bolt holes.
All the cylinder head bolts must always be changed
after removal. There is no cylinder head retightening
operation.
Preseating the gasket
Tighten all the bolts to 3 daN.m, then angle tighten to
100˚ ± 4˚ in the order shown below.
Wait 3 minutes settling time.
Tightening the cylinder head:
– cylinder head tightening is carried out in stages, and
the following procedure is applied successively to
bolts 1-2 then 3-4, 5-6, 7-8 and 9-10,
– slacken bolts 1-2 until they are completely free,
– tighten bolts 1-2 to 2.5 daN.m, then angle tighten to
213 ± 7˚,
– repeat the slackening and tightening operations for
bolts 3-4, 5-6, 7-8 and 9-10.
There is no cylinder head retightening operation.

REFITTING
For refitting operations, use the same procedure as for
removal in reverse.
IMPORTANT: you must change the copper gasket at
the turbo oil inlet connection.
IMPORTANT:
Before starting the engine disconnect the pressure
regulator manifold on the high pressure pump.
Then run the starter motor until the oil pressure
warning light goes out (wait a few seconds).
Reconnect the regulator, preheat and start the engine.
Run the engine at idling speed and check that there
are no leaks at the oil connections.
Erase the fault and check the turbocharging pressure
solenoid valve sensor.

Special precautions
!Before refitting, make sure that the lubrication is
correct for the turbocharger bearings. To do this
activate the starter motor having first
disconnected the high pressure manifold regulator
(do not start the engine) (erase the computer
memory). Sufficient oil should arrive via the oil
pressure pipes (place a container below). If this is
not the case, change the lubrication pipe.
!Ensure that no foreign bodies enter the turbine or
compressor during the refitting operation.
!If there has been a fault in the turbocharger, check
that the air-air exchanger is not full of oil.
If the air-air exchanger is full of oil, it must be
removed, flushed with a cleaning agent and then
left to drain properly.
!Check that the turbocharger oil return pipe is not
partially or completely blocked by scale. Check
also that it is perfectly tight. If not, replace it.

REMOVAL
Put the vehicle on a 2 post lift.
Disconnect the battery.
Remove (for the Scénic):
– the front right hand grille as well as the mounting
bolts of the left hand grille,
– the closure panel of the scuttle,Remove (all types):
– the turbocharging air ducts between the exchanger
and the engine,
– the pre-catalytic converter mountings to the turbo.
Loosen the exhaust pipe clamp mounting.
Remove:
– the pre-catalytic converter stay (1),
– the catalytic converter mountings on the precatalytic
converter and remove this by moving the engine
towards the cooling system,
– the oil return pipe (8),
– the starter electrical connections.
– the starter mountings,
– the starter motor.
REFITTING
To remove, proceed in the reverse order.
Check the presence of the starter motor centring
dowel.
