Remove:
– the battery,
– the engine undertray.
Drain:
– the cooling circuit through the bottom hose of the
radiator,
– the gearbox and the engine (if necessary),
– the refrigerant circuit (if fitted) using filling equipment.
Remove:
– the front wheels along with the mudguard,
– the sub-frame and body tie rods,
– the track rod ends,
– the brake calipers (as well as the ABS sensors, if
fitted) and secure them to the suspension springs,
– the shock absorber base bolts,
– the heat shield (A) as well as the gearbox control,
– the clip (1) of the catalytic converter and secure this
to the body.
– the front bumper,
– the horn,
– the two mountings for power assisted steering
hoses on the right hand side of the sub-frame,
– the nut and the eccentric bolt of the steering shaft
yoke, after pushing back the guard.SPECIAL NOTES FOR VEHICLES FITTED WITH A
DRIVER'S AIRBAG
Remove (for the Scénic):
– the windscreen wiper arms using tool Elé. 1294-01,
– the front grilles,

WARNING
In order to eliminate any risk of damaging the
rotary switch under the steering wheel, observe
the recommendations below:
!Before the steering column and the steering
rack are uncoupled, the steering wheel MUST
be immobilised with the wheels straight for the
duration of the operation using a "steering
wheel locking tool".
!If there is any doubt regarding the correct
alignment of the rotary switch, the steering
wheel must be removed so that the alignment
procedure described in the "AIRBAG" section
can be applied.
REMINDER: in this case, only qualified
personnel who have received training may carry
out the operation.

– 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.

Fit tool Mot. 1040-01 under the engine sub-frame.
Lower the lift until the tool touches the ground.
Remove the sub-frame mounting bolts and take out
the engine and transmission assembly by lifting the
body.
When starting to lift the body, ensure that the catalytic
converter is removed and extract the radiator from its
upper mountings (then place it on the sub-frame).
NOTE: for any operation requiring the engine, gearbox
and sub-frame assembly to be separated, take care to
mark the position of tool Mot. 1159 on the sub-frame.REFITTING
The alignment of the sub-frame with the body will be
made easier by positioning two threaded rods
Mot. 1233-01 in the two front mountings of the sub-
frame on the body.
When lowering the body onto the engine - gearbox
assembly, ensure that the catalytic converter is
refitted.
Tighten the sub-frame mounting bolts to a torque of:
– 6.2 daN.m at the front,
–10.5 daN.m at the rear.
See section 19 "Suspended engine mounting" for
the tightening torques for the engine and gearbox
assembly mountings.
Refitting is the reverse of removal.
Refit the heat shields correctly.
Apply Loctite FRENBLOC to the caliper mounting
bolts and tighten them to the recommended torque.
Press the brake pedal several times to bring the
pistons into contact with the brake pads.
Fill:
– the engine and gearbox with oil (if necessary),
– the cooling circuit and bleed it (see section 19
"Filling - bleeding").
Fill the refrigerant circuit using the filling equipment (if
fitted).

Idle speed correction
IDLING SPEED CORRECTION ACCORDING TO COOLANT TEMPERATURE
CORRECTION OF THE IDLING SPEED WHEN THE POTENTIOMETER IS FAULTY
If the accelerator pedal potentiometer is faulty, idling speed is held at 1200 rpm.
If the information from the accelerator pedal position potentiometer and the brake switch information does not
correspond, the speed is changed to 1250 rpm.
CORRECTION OF THE IDLING SPEED ACCORDING TO THE GEAR RATIOS
The running idling speed is modified according to the gear engaged in the gearbox:
– in 1
st, 2nd and 3rd gears the speed is 835 rpm.,
– for other gears the speed is 925 rpm.

Thermal plunger

13-19
Thermal plunger
The three thermal plungers are located on a water unit
fixed under the manifold at the engine - gearbox joint.
The objective of the system is to reheat the coolant.
The thermal plungers are supplied with 12 volts by
two relays. One relay controls two thermal plungers,
and the other relay controls one thermal plunger. This
enables control of one, two or three thermal plungers
as required.
The resistance of the thermal plungers is:
0.45 ± 0.05 Ω at 20˚C. Control strategy
When the thermal plungers are operating the idling
speed is brought to 900 rpm.
Thermal plungers cannot operate in the case of:
– preheating,
– post heating,
– heated windscreen selected,
– engine speed below 700 rpm.,
If the conditions mentioned above apply, the thermal
plungers are controlled according to a characteristics
map linked to the air and coolant temperature.
Unshaded zone: Thermal plunger not supplied
Shaded zone: Thermal plunger supplied
