ISMOUNTING

The car is set on a two-column lifting stand.
The battery is disconnected.
The cooling circuit is emptied at the filling stopper placed at the lower part of the radiator.
The following are taken apart.

- the distribution belt (see Chapter “Distribution belt”);
- the extending pulley / runner (1);
- the fixing screws of the water-pump.

The water-pump is taken out at the upper end of the engine compartment.

LEANING

It is very important that the fitting surfaces of the aluminum parts should not be scratched.
Use Decapjoint to dissolve the particles of fitting that are left stuck to them.
The paste is applied onto the cleaning surface and then you wait for approx. 10 minutes,

then it is removed with a wooden spatula.

During this operation you should used protection gloves.

EMO UNTING

The watertightness of the water-pump is done with LOCTITE 518; the H cord has the

thickness of 0,6-1 mm and must be applied according with the chart below.

The distribution belt is re-mounted (see Chapter “Distribution belt”).
The cooling circuit is filled and drained (see Chapter “Filling and Draining”).

DISMOUNTING - REMOUNTING EXHAUST

The catalytic converter, when in operation, reaches high tempera-

tures, and consequently must not co me in touch with flammable materials, which
would lead to self-combustion.

The catalytic converter will be kept out of mechanic shocks.

D

ISMO UNTING

In order to take apart the noise-damper system 1, the following operations are to be

performed:

The screw-nuts 2 of the fixing collar, between holder 3 and noise-damper 1, are

loosened;

The two elastic fixing stands of the damper are taken apart, at the back on the car

bodywork;

The noise-damper system is pulled and taken out.

In order to take apart the assembled holder 4, the following operations are to be performed:

Collar 4 is taken off and the assembled holder is disconnected from the catalytic

converter;

The elastic stands of the assembled holder are taken off;
The screw-nuts of the fixing collar 2 are loosened and the assembled holder is

taken out by gently rotating, and pulling it towards the front.

In order to take apart the catalytic converter system 6, the following operations are to

be performed:

The engine shield is taken apart;
The two screw-nuts 7 for the fixation of the engine shield on the two stud-bolts on

the exhaust gallery flange;

The fixing screws of converter stand 5 are taken off;
The oxygen probe is taken apart;
Collar 4 is taken apart, and the catalytic converter assembled on the assembled

holder is disconnected;

The catalytic converter is taken out.

R

EMO NTARE

The mounting operations are performed in the reverse order.
Make sure there perfect watertightness between the elements of the exhaust system,

by using the Wurth watertightening paste, along the (inner part of the) joining stretch,
between the gas expansion chamber and the catalytic converter (0.014 kg), and between
the noise-damper and the expansion chamber (0.013 kg);

The fittings of the oxygen probe will be replaced for each taking-apart operation;
The tightening couple between the damper and the holder: 3.5 daNm +/-0.5.
