When working in the engine compartment, take
care as the radiator fan(s) may start up unexpect-
edly (risk of being cut).
To avoid any risk of serious burns when the engine
is hot:
-do not open the expansion bottle cap,
-do not drain the cooling system,
-do not open the bleed screw(s).
WARNING
Before the operation, protect the electrical accesso-
ries to prevent any risk of shor t circuiting and pro-
tect the belts to avoid damaging them.
WARNING
The coolant helps to keep the engine running prop-
erly (heat exchange).
The system does not operate using pure water.
WARNING
The seals m ust always be replaced.

I - REFITTING PREPARATION OPERATION
aparts always to be replaced: coolant tempera-
ture sensor seal.
aUse SURFACE CLEANER (see Vehicle: Parts
and consumables for the repair) (04B, Consuma-
bles - Products) to clean and degrease:
-the seal housing in the water chamber,
-the seal mating face of the coolant temperature
sensor if reused.
II - REFITTING OPERATION
aRefit:
-the coolant temperature sensor fitted with a new
seal,

aConnect the coolant temperature sensor connector. IMPORTANT
The circuits are designed to be pressurised, so be
careful at high temperatures (risk of serious burns).
Do not remove the cap from the expansion bottle
while the engine is hot.
Take care when carrying out a repair under the bon-
net, as the radiator fan(s) may start to operate with-
out warning.
Do not open the bleed screw(s) with the engine run-
ning.

ries to prevent any risk of shor t circuiting and pro-
tect the belts to avoid damaging them.

EXHAUST
Exhaust: Precautions for the repair
19B
I - PARTS AND CONSUMABLES FOR THE REPAIR
1 - Parts always to be replaced:
- the exhaust trunking (if fitted)
- the seal or sealing ring on the connection between the
catalytic converter or catalytic pre-converter and the
rest of the exhaust system
- the exhaust clip(s) (if fitted)
2 - Consumables (see part no. in Technical Note
5068, 04B, Consumables - Products):
- exhaust mastic
- surface cleaner
- abrasive pads
II - ADVICE TO OBSERVE
1 - During removal and refitting, the catalytic converter
or catalytic pre-converter must not receive any knocks
or impacts as this could damage it.
2 - The whole exhaust pipe is made of stainless steel.
3 - After working on the bracket between the catalytic
converter or catalytic pre-converter and the rest of the
exhaust system, ensure that the connection is perfectly
sealed.
To do this:
-clean the pressure faces of the connection using the
ABRASIVE PADS,-degrease the pressure faces of the connection using
SURFACE CLEANER and clean cloths,
-always replace the seal or sealing ring on the connec-
tion.
III - SPECIAL NOTES ON THE SINGLE UNIT
EXHAUST PIPE
1 - Cutting the single unit exhaust pipe
The exhaust pipe is a « single unit type » .
To replace different parts of the exhaust system it must
be cut.
To do this be sure to carry out these precautions in the
following order:
-correctly identify the area to be cut, as explained be-
low,
-use the cutting tool correctly (Mot. 1199-01),
-position the exhaust trunking correctly.
2 - Identifying the area of the exhaust system to be
cut
Two marks made on the exhaust system define the
area to be cut (see Exhaust: Parts and consumables
for the repair) (see MR for vehicle concerned, 19B,
Exhaust).
Example of cutting area Special tooling required
Mot. 1199-01Exhaust pipe cutter (diame-
ter 35/50 mm and diameter
50/65mm). Complete kit in a
case.
IMPORTANT
Do not park and run the engine in a place where
combustible substances and materials such as
grass or leaves can come into contact with the hot
exhaust system.
IMPORTANT
Catalytic converters contain ceramic fibres , these
are contained within a closed unit, and cannot dis-
perse. Drilling or cutting catalytic converters is pro-
hibited.

EXHAUST
Exhaust: Precautions for the repair
19B
Before cutting the exhaust system, draw a line (D) be-
tween the two marks (P1) and (P2) .
The distance between the two marks on the exhaust
pipe is (X1) : 90 mm (all types except RENAULT
SPORT).
The distance between the two marks on the exhaust
pipe is (X1) : 80 mm (RENAULT SPORT).
3 - Operate tool Mot. 1199-01Fit the (Mot. 1199-01) (1) on the exhaust pipe.
Tighten the two bolts on the tool until they touch the
pipe in order to clamp the tool onto the pipe.
Turn the cutting tool using the handle and pressing it
against the pipe (as indicated in the diagram above).
Tighten the two bolts on the tool whilst cutting, until the
pipe is completely cut.
Once the pipe is cut, file and deburr the end of the pipe
to be used on the vehicle again.
4 - Positioning the exhaust trunking
100649
Note:
For CLIO II RENAULT SPORT with F4R*730,
F4R*732 and F4R*736 engines, the cutting area is
shown by a single mark on the exhaust pipe.
Cut the exhaust pipe by placing the (Mot. 1199-01)
on the mark.

Note:
Do not over-tighten the tool onto the pipe to avoid
deforming it.
WARNING
Do not reuse an old exhaust trunking.

EXHAUST
Exhaust: Precautions for the repair
19B
Exhaust trunking with 1 bolt
Exhaust trunking with 2 bolts
Fit the exhaust trunking onto the part of the exhaust
system fitted to the vehicle.
Position the pipe onto the lugs (2) inside the exhaust
trunking.
Tighten the exhaust trunking bolt(s) slightly (depending
on the version).
Position the second part of the exhaust system under
the vehicle, fitting it in the exhaust trunking.Position the second exhaust pipe onto the lugs inside
the exhaust trunking.
Check that the two cut marks (3) are aligned (if applica-
ble).
Position the trunking so that there is no risk of contact
between its bolt or bolts and the heat shields.
Torque tighten
-the exhaust trunking nut with 1 bolt (25 N.m) (if fit-
ted),
-the exhaust trunking nuts with 2 bolts (18 N.m) (if
fitted).
Check the following and deal with if necessary:
-no underbody contact between the exhaust system
and the heat shields,
-all of the heat shields are present and secure.
Start the engine.
Check that there are no leaks: deal with any leaks.
