REMOVAL
To remove the manifold, the throttle body must
be removed (see previous pages).
There are no special notes for removal.
The inlet manifold is fitted with an electrical
heater (2) with a PTC type resistance (positive
temperature coefficient).
This is mounted in the inlet manifold, opposite
the throttle, and is secured by a circlip.
The heater is fed via a relay by the computer up to
a coolant temperature of 68°C.
If the coolant temperature sensor is faulty, the
heater is permanently fed.

REFITTING
When refitting, replace the manifold gasket and
bleed the cooling circuit.

K7M engine
Unscrew the steel pipe (11) which goes to the
manifold from the EGR solenoid valve mounting
(release the clip first).
All engine types
Remove the two bolts from under the manifold
which mount the wiring retaining bracket.

From the manifold, disconnect:
- the pipe (12) connected to the absolute
pressure sensor,
- the pipe (13) connected to the brake servo,
- the fuel supply and return pipes.
Disconnect the two hoses from the canister bleed
solenoid valve (14).
Remove the four lower mounting nuts then the
five upper mounting bolts.
99371R
Remove the manifold.
REFITTING
Renew all gaskets and seals which have been
removed.
Refitting is the reverse of removal.
Remember to reclip the clip mounting the EGR
pipe.

EXHAUST

EXHAUST PIPE MOUNTINGS UNDER THE BODY
The exhaust pipe is attached under the body using
rubber mountings.
These may generally be released by hand by lif-
ting the exhaust pipe.
In certain cases however, the retaining bolts for
mounting (A) under the body may have to be
slackened to release the rubber mountings more
easily. The catalytic converter reaches high temperatures
during operation and consequently the vehicle
should never be parked in an area where there is
combustible material which could come into
contact with the exhaust and pose a fire risk.
Under certain conditions, this type of material
could catch fire.
IMPORTANT:
- sealing between the exhaust manifold gasket
face and the catalytic converter must be per-
fect,
- any seals removed
MUST be renewed (especial-
ly at the catalytic converter flange),
- during removal and refitting the catalytic
converter should not be subjected to repeated
mechanical impacts as it may be damaged.
CUTTING THE EXHAUST PIPE
The exhaust pipes are of monoblock construction.
This means there is no break between the inlet to
the catalytic converter or the expansion chamber
and the silencer outlet.
If one of the components requires replacement as
an After Sales operation, the exhaust pipe must
be cut.
To do this:
- mark up the cutting line correctly,
- use the cutting tool Mot. 1199,
- fit the After Sales sleeve.
