ENGINE
DESCRIPTION
deaner
The air cleaner is mounted ,on top: of the· engine and serves
both to clean the induction air and as an induction silen-
cer.
The air cleaner•cartridge is made of a special grade of
paper which may not be washed or moistened. The only
service measures are blowing through with compressed
air or replacement of the cartridge.
To preheat the induction air in cold weather, the inlet of
the downward-pointing, air·deaner snorkel con be placed
behind a special preheater plate, screwed to the exhaust
flange of the lefthand cylinder head. In warmer weather,
when preheating is no longer necessary, the upper part
of the airideaner is loosened and turned so that the snor-
kel inlet comes in front of the preheater plate. During
model 1972 an air cleaner made of plastic was intro-
duced. When altering the pre-heater position loosen the
clamp around the pre-heater snorkel and turn the snorkel
to the desired position.
Winter position should be used at permanent tempera-
ture below 50°F (+10°C).
As from model1970 for the U.S.A. the cars are equipped
with a thermostatically controlled preheating valve (see
section 232).
