BRAKE FLUID
PERIODICITY OF THE BREAK FLUID CHANGE
The manufacturing conception of the brakes equipping the Dacia vehicles, especially
the di sks brake type (F 54 inner empty pistons, low qua ntity of fluid in t he c ylinders,
sliding calipers avoiding existence of a fl uid reserve in the less cooled area of t he wheel)
enable t he m aximum re jection of fluid vapori zation ri sk, even in c ase of intensive using of
brakes (mountain are a). The current bra ke fluids are subject in all cases to a slight degradation during the fi rst
months of use by a slight humidity absorpt ion seri es (see the Vehicle Warra nty and
Maintenance Booklet, for brake fluid change)
LEVEL COMPLETION
The wear of brakes pads and shoes generate a gradually diminution of brake fluid level
in its reservoi r. It is useless t o compensate t his diminution, because the level will be re -
stored in the moment of next changing the brake pads and shoes. Obviously, in the mean-
time, the level of brake fl uid in re servoir must not go down bellow the minimal mark.
HOMOLOGATED BRAKE FLUIDS
The mixture i n t he bra king circuit of two non compatible brake fluids may leads to loss
important risks mainly due to gasket damage
In order t o avoid such risks, it is obligatory t o use bra ke fluids checked and approved by
our laboratories and which are accordi ng to Norm SAEJ 1703, DOT 4.

DISMOUNTING
Release
the climate maintenance assembly from under the dashboard, dismounting beforehand
the central console, the documents compartment, the lower casing, the dashboard. Unscrew the attachment screws of the turbine deflector.
Unscrew the attachment screws of the blower.
Disconnect the blower from the blower wiring.
REMOUNTING
Perform in the reverse order the dismounting operations.

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.
