It must be said that in infrequent cases the indication of the faulty cylin-
der is not exac t; the calculator can declare cylinder 1 as not working,
while it is not faulty. So, you have to check this cylinder as a priority,
an d if everything s correct, the other cylinders will be checked. These
indications will only be used if the polluting or destructive combustion
m isfires are present.
SUGGESTION
In this case, the problem is probably caused by an element which acts
only on this cylinder:
- its injector
-the spar k plug of this cylinder
-the plug of the spark for that cylinder.C YLINDER 1 IS

AIR CONDITIONING

62 - 1
GENERALITIES
GENERALITIES
The purpose of the a ir conditioning unit i s to produce a decrease of t he temperature in the
passengers compartment a nd to obtain a l ower value t emperature compared to the external
environment one, reducing in the same time the air moisture.
MAINTENANCE
For a vehicle equipped with air conditioning, it is recommended a frequent checking of the
refrigerating agent level. During the year it is recommended:
- the checking of the refrigerant fluid filling;
- the cleaning and the air-blowing of the condenser and the cooling radiator fins;
- the checking of the condensation removal pipe on order not to be clogged.
For important leakage repair, for any components replacement (compressor, condenser, etc)
and if moisture was noticed in t he air conditioning circuit, the dryer filter tank is to be replaced
and the unit draining is to be performed. The same is valid also in case the conditioning circuit
remains open without protection covers more than 10 minutes.
IMP ORTANT
Duri ng winter, it is recommended the frequent start of the system, in order to pro-
long the lifetime of the compressor and of the whole system.
The vehicle equipped with an air conditioning system shall be not exposed for more
than 20 minutes i n painting c abin where there are temperatures higher than 80 °C.
It is obligatory the use of the refrigerating agent and compressor oil type prescribed
by the manufacturer. It is absolutely forbidden to perform welding on the elements of the air condition
circ uits. The filling of the air conditioning system can be pe rformed only by m eans of charging
units and observing the instructions of the manufacturer. For mechanical or body
operations it is recommended pi ping protection in order to avoid their disconnection
by accident. Avoid the drip of the oil compressor on the painted vehicle body.
For component replacement implying the circuit draining, it is absolutely necessary
the use of new parts and of a special oil for compressor.
