NOTE! When anti-freeze is added, it must first
be
mixed with a suitable quantity of water,
as
full circula-
tion cannot take place until the thermostat opens. If pure
anti-freeze is added, there is
still a risk
of
the engine
being damaged by ice
if
the anti-freeze does not mix with
the engine
coolant quickly enough.

FUEL SYSTEM
The engine is fitted with Bosch electronically controlled
fuel
injection equipment
or
with a Zenith-Stromberg car-
buretor.
The
fuel tank is placed underneath the car, between the
rear
wheels. The fuel level transmitter
is
fitted on top of
the tank.
The evaporation
loss control unit includes a charcoal
canister which is placed in the engine compartment. It
absorbs the vapor from the tank when the engine is not
running. The
charcoal
is
purged when the engine is run-
ning. This
is
achieved by fresh air which
is
sucked through
to the air
cleaner.
The fuel filter (fuel injected engine only) and the canis-
ter
filter should be replaced at intervals according to the
directions given in the maintenance program.
Air Cleaner
The air cleaner is located on the left-hand side
of
the
engine. The
replaceable cleaner insert should be changed
in accordance with the maintenance program.
If the car is
often driven on dusty roads, the
filter should be changed
more frequently. The
filter element is made
of
a special
type
of
paper and must not
be
washed
or
moistened, al-
though it may
be
carefully cleaned with low pressure com-
pressed air. The air
cleaner housing and cover should
be
wiped
off
from time to time.
The
fuel pump
for
the fuel injected engine is electri-
cally
operated and is located behind the fuel tank, together
with a separate
filter. A lid in the trunk provides access
to the
filter which should
be
changed in accordance with
the maintenance program. The
fuel pump
for
the car-
buretor equipped engine is
mechanically operated and
located on the engine cylinder block.
