FIAT IDEA LPG
LPG TANK
The vehicle has a (pressurised) tank A -
Fig. 3for LPG in a liquid state that is
toroidal in shape and located in the spare
wheel housing, where it is suitably pro-
tected.
The LPG in the tank Ais always in both liq-
uid and gaseous state, in a physical balanced
condition.
The liquid, which cannot be compressed,
dilates by around 0.25% for each increase
in temperature of one degree. For this
reason a suitable space allowing the in-
crease in volume of the liquid for all fore-
seeable temperature increases is guaran-
teed (e.g. car parked in the sunshine in
summer), without compromising tank in-
tegrity.
There is a safety valve that automatically
limits tank refilling (during refuelling) to a
maximum level of 80% (liquid) of its total
capacity.Periodically (at least once
every six months) it is advis-
able to let the LPG in the tank
run out and, at the first refu-
elling, check that it does not exceed the
maximum capacity of 31 litres (with a
tolerance of 2 litres excess) (see in-
structions in ‘Capacities’ paragraph in
this Supplement). If the value exceeds
31 litres, please go to a Fiat Dealer im-
mediately.
LPG TANK CERTIFICATION
The LPG tank is certified in accor-
dance with current regulations.
In Italy, the tank has a life of 10 years
as from car registration. If the car
has been registered in a different
country from Italy, the life of the
LPG tank and test/inspection proce-
dures may vary depending on the
laws in force in that particular coun-
try. In any case, when the time lim-
it in the individual country has run
out, go to a Fiat Dealer to have the
tank replaced.There is a plate on the tank B - Fig. 3con-
taining the following information:
- homologation country identification and
homologation number;
- type of gas for it has been designed
(LPG);
- name of tank manufacturer;
- tank test pressure (30 bar);
- maximum refilling percentage (80%);
- tank dimensions;
- nominal tank capacity in litres;
- tank manufacture date (month/year);
- tank serial number.
