Exhaust Assembly
ATTENTION !
Descending pipe in operation, may reach high temperatures and consequently must not
come in contact with flammable materials which may lead to their auto-ignition.
Catalytic converter is to be mechanical shock protected.
DISMOUNTING
I
n order to dismount the noise absorber assembly (1), lift the vehicle on an elevator and
perform the following operations:
Loosen the nuts (2) of the attachment collar between the expansion chamber (3) and the
noise silencer (1).
Dismount the three attachment elastic supports of the noise absorber, on the carriage
body, rear part.
Release the noise silencer.
In order to dismount the assembled expansion chamber (3), perform the following operations:
Dismount the collar (4) and disengage the expansion chamber assembled with the de-
scending pipe.
Dismount the three elastic supports of the assembled expansion chamber.
Loosen the attachment collar nuts (2) and remove the assembled expansion chamber by
easy rotation and onward pulling.
In order to dismount the descending pipe assembly (6), perform the following operations:
Dismount the engine shield.
Dismount the catalytic converter attachment nuts (7) on the two studs of the exhaust manifold
flange.
Dismount the attachment screws of the converter support (5).
For EURO 96, dismount the oxygen sensor located in upstream of the catalytic converter.
For EURO 00, dismount the oxygen sensors located in upstream, consequently, in
downstream of the catalytic converter.
Dismount the collar (4) and disengage the assembled catalytic converter from the assembled
expansion chamber.
Remove the descending pipe.
REMOUNTING
Perform the dismounting operations in the reverse order.
Ensure a perfect sealing between the exhaust assembly elements, using sealing paste Wurth,
on the joining area length (inside) between the noise absorber – expansion chamber (0.013 Kg);
The oxygen sensor gasket is to be replaced at each dismounting.
The tightening moment between noise absorber and expansion chamber is: 3.6 daNm.
The tightening moment of descending pipe attachment nuts on the exhaust manifold flange is:
2 daNm.
Tightening moment between the catalytic converter and expansion chamber: 2.5 daNm.
All elements are to be assembled having the ambient temperature.

Fuel tank
IMPORTANT:
During the intervention on the fuel tank
and on the fuel supply circuit, at the working
place, do not smoke and do not bring near
any incandescent parts.
Fuel tank draining is not implying tank
dismounting. The access is allowed through the
vehicle interior (trunk).
Dismount:
- trunk carpet;
- visiting whole cover (by dismounting the
three attachment screws);
- disconnect the rapid coupling A;
- adjust to exit A, an enough long hose to
be introduced in a vessel outside the vehicle.
From the fuse box located inside the engine
compartment, remove the H relay of the petrol
pump and bridge across plugs 3 and 5 of the
relay connector, ensuring the petrol pump
working (12V).
Stop the pump working when petrol
discontinuous draining s noticed.
Detach the plugs bridge.
Mount the petrol pump relay.

FILLING CAP
Fuel tank
The fuel tank is having a filling cap, sealed-type, with key. The filling cap for unleaded fuel has
a filler whole incompatible with a classical filling gun (lead has a negative effect upon the de-
pollution system : oxygen sensor and catalyst).
In case of vehicle overturning, the anti-overturning valve is getting blocked, avoiding in this
way, the petrol leakage towards the carbon can.
