COOLING - EXHAUST - TANK
The heating radiator has no valve.
The fluid circ ulation is permanently done in the heating radiator, this leading to t he engine
cooling.
FILLING
Open the purging screw located on the water pipe between engine and climate control radiator.
Fill up the circuit by the expansion vessel hole
Tighten the purging screws in the moment when the fluid is flowing in a continuos jet.
Start the engine, maintaining it at 2500 rot/min.
Adjust the fluid level in the expansion vessel, during about 4 minutes.
Close the cap of the expansion vessel.
PURGING
Let the engine run for 10 minutes at 2500 rot/min, until engine fan starting (necessary
period for automatic gas purge).
Check if the fluid level in the expansion vessel is nearby the mark “Max”.
Do not open the purging screws with the engine running.
Ret ighten the expansion vessel cap with the warm e ngine.

The operation of the engine fan is controlled by the UCE injection, as follows:
1. For vehicles without air conditioning –cooling engine fan cooling is starting when water temperature is over 99°C;
– cooling engine fan cooling is stopping when water temperature is lower than 96°C.
2. For the vehicles with air conditioning. -cooling engine fan cooling is starting on first step when water temperature is over 99°C;
- cooling e ngine fan c ooling is start ing on second step when water temperature is over
104°C; - cooling engine fa n cooling is switching from second step to first step, when water
temperature is lower than 101°C; -engine fan cooling is stopping when water temperature is lower than 96°C.

I. CO NSTANT EFFECT TO THE PEDAL
EFFECTS
T ough pedal:
High effort for small deceleration.
Elastic pedal
In order to di agnose, an i ncident where
the use was normal is to be analyzed and two
tests are to be pe rformed:
1. While driving the vehicle :
Interpretation test: pedal stroke/ deceleration
rate.
2. While vehicle i s stopped, engine c ut.
A dditional test of brake pedal press:
Pe rform five c onsecutive pressings on the
brake pedal in order to vacuum the
servobrake, before taking into consideration
the test result.
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 brake pedal,
in order to vacuum the servobrake before
taking into consideration the test result.
Floor pedal
The test i s to be performed with stopped
vehicle and cut engine.
REMARK :
Perform 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 t he disk ( non-c onform )
- heating, prolonged bra king with c onstant
pedal press
- Stuck piston
- R igid duct narrowed (flattening)
- Air presence in the circuit: defective 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 l eak (check the sealing of the
b raking system components)
- Sealing gaskets defects of the two brake
pump circuits.
- Brake fluid having high temperature

II. CONSTANT EFFECT AT BEHAVIOUR
EFFECTS
Brakes not accomplishing the required
b raking distance
Vibrating brakes
When braking, the vehicle ( front part)
is left/right deviating
Braking
Heating brakes POSSIBLE CAUSES
- Non-uniform worn brake linings (backing
off);
- Brake l inings slightly gr eased;
- Springs with modified characteristics.
- Brake disks with high wobbling;
- Inconstancy brake disks width;
- Particles abnormal deposit on brake disks
(oxidation between linings and disk).
- Front axle suspension, steering (to be
checked);
- Stuck piston;
- Tires – wear, inflation pressure;
- R igid duct narrowed (flattening).
- Stuck piston;
Automatic adjustment : hand brake cable very
tighten.
REMARK :
Automatic recovering is performed by
means of the brake pedal, if there is no ab-
no rm al t ensi on in the hand brake cable
when released (hand brake released).
- Return spring.
- Insufficient hydraulic stroke of the brake
pump, not allowing the return at rest of the
brake pump pistons ( brake pump remaining
under pressure);
- St uck pistons or hardly returning;
- R igid duct narrowed (flattening);
- Def ective adjustment of the hand brake
control.

Repairing general conditions
The replacement (reparation) operations of the weldable elements described in this chapter
are specified subject to: cutting out of the parts to be replaced, access to the welded elements,
tools and checking devices accessibility , etc.
In case the vehicle body has suffered important deformations it is recommended the straight-
ening of the damaged body elements, by means of some hydraulic presses.
For this range of vehicles, the elements resistance structure which are affecting the vehicle
s ecurity, are not to be partially replaced (not to be cut), but entirely.
After welding detaching, the body elements must remain straight, without breakage or cracks,
the possible holes being covered out with filling material or by tinning. The body elements sur-
faces are to be pickled ( to eliminate possible oxidation marks), dried and initially applied a paint
layer. The electric welding detaching of the body elements, may be performed as follows:
- with a well sharpen c hisel, t his method may lead t o parts de formation or e ven pa rts
breaking. - by using some extractors equipped with steel cutter type Brendeo or Pickvant (max. 6
mm) having the cutting head shaped as shown in pict.1.
1. Centering point
2. Sharpen slope
3. Drill acting edges
4. Gap for catching the welding material
P = aprox. 0.4 mm
Whatever m ethod is used, the remaining element must be in good order and to a llow per-
forming of a good quality welding point.
The plates cutting it is recommended to be performed (subject of importance and thickness)
using manual scissors or pneumatic portable tools for plates cutting. During cutting or welding of the body elements it is necessary to protect the electric wiring
from the interior of the body structure. The cutting, welding, or strengthening operation done on body welded elements, are to be
performed on body checking/ straightening benches recommended by the producer.
IMP ORTANT !
When removing or straightening the body resistance elements, it i s forbidden the
total or partial heating, in order to avoid the mechanical resistance and metal elastic-
ity de creasing.
