COOLING - EXHA U ST - FUEL TANK
The fuel tank has a watertight stopper; the inlet for the fi lling with unleaded fuel has a
filling orifice incompatible with a classical filling gun (as lead has a negative effect on the
anti-pol lution system, the oxygen probe and the catalyst).
THE ANTI - TILT VA L V E
In case the car is tilted / overthrown, the valve gets blocked, thus avoiding petrol from spilling
towards the carbon canister or the filling inlet.
T
HE SECURITY VALV E
In case the petrol vapour recycling circuit is stopped up, the security valve avoids over-pres-
sure or under-pressure in the tank. It is mounted with the red-marked end towards the joining tube “T”, and with the white-marked
en d towards the tube linking it to the filling inlet.

BRAKING SYSTEM DIAGNOSTIC
I. CONSTANT EFFECT TO THE PEDAL
EFFECTS
To u g h pedal:
High effort for small deceleration.
Elastic pedal
In order to di agnose, an i ncident where
the use was normal is t o be analyzed and
two tests are to be perform ed:
1. While driving the vehicle :
Interpretation tes t: pedal stroke/
deceleration rate.
2. While vehicle i s stopped, engine c ut.
Additional test of bra ke pedal press:
Pe rform five c onsecutive pressings on the
brake pedal in order to vacuum the
se rvobrake, before taking into
consideration the test re sult.
Long pedal
The test i s to be performed with stopped
vehicle and cut engine. REMARK:
It is neces sary to perform five
consecutive pressings on the brak e
peda l, in o rd er t o v a cuum t he
s ervobrake before takin g into
consideration the test result.
Floor pedal
The test i s to be performed with stopped
vehicle and cut engine.
REMARK :
Perfor m five consecutive pressings on
the brake pedal, i n order to vacuum the
s ervobrake before takin g into
consideration the test result. POSSIBLE CAUSES
- Assi stance defect
- Brake linings:
- greasy
- stacking to the disk ( non-conform )
- heating, prolonged bra king with c onstant
pedal pre ss
- Stuck piston
- Rigid duct narrowed (flattening)
- Air presence in the c ircui t: de fective
purging
- Internal leak in the braking circuit.
- Leak of fluid from reservoir (external fluid
leak from braking circuit).
Automatic adjustment : ha nd brake c able too
tighten. - Important and asymmetric wear of the
b rake linings
- St roke too ample between the servobrake
pushing rod and the brake pump
- Brake fluid having high temperature.
- Hydraulic leak (check the sealing of
the braking system components)
- Sealing gaskets defects of the two
b rake pump circuits.
- Brake fluid having high temperature

STEERING ASSEMBLY

PUSHER
PUSHER ADJUSTMENT
The pusher adjustment shall be performed taking into consideration, the wear degree of the
rack and the pusher.
1. Pusher
2. ”0” ring
3. Pusher spring
4. Assembled threaded plug
When mounting distribute 23 + / - 5cmc
of grease II Li Ca Pb with MoS2 for: the
rack, the gear, the pusher and the spring, the
inner surface.
ADJUSTEMENT METHOD
The clearance adjustment of the pusher is performed by tightening the threaded plug at the
required moment of 1+/-0,2 daNm and unscrewing it ˘ round.
The moment for the gear rotation will be
about 0,15 daN.m (maximum accepted 0,25
daN .m ) on the whole length of the rack or
the rack gliding effort of 25 daN (maximum
accepted 40 daNm ) without rigid points.
Securing of the unscrewing of the threaded
plug is perform ed by the distort ion of t he
securing element of the assembled threaded
plug towards the casing in two antipodal
points.

MECHAN ICAL ELEMENTS CONTROL
37BRAKE FLEXIBLE HOSES
The SUPER NOVA vehicles are equipped with flexible hoses with copper gaskets in order
to ensure the sealing.
PRECAUTIONS IMPOSED TO BE RESPECTED WHENDIS MOUNTING – REMOUNTING A RECEIVER
OR A BRAKE FLEXIBLE HOSE
D ue to security reasons, in order to avoid brake flexible hose twisting and the risk to get i n
contact with the suspension elements, it is necessary to observe the following operations sequence.
