alcohol
It
will
not

evaporate

or

with
either

high

temperature
thermostat
It

flows

freely
transfers

efficiently
and
will
not

clog
the

products
This
coolant
can
be
used

throughout
tlie

seasons
of
the

year

Whenever

any

is

changed
the

Duirng
partial

operation
of

the

enigne

the
intake

manifold

sucks
the

blow

by

through
the

valve

Normally
the

capacity
of
the

valve
is
sufficient
to

handle

any
blow

by
and

a
small

amount
of

ventilating
air

The

ventilating
air

is
then

drawn
from

the
clean
side
of

the
carburetor
air

cleaner

through
the

tube

connecting

carburetor

cleaner
to
rocker

Under
full

throttle
condition
the
manifold
vacuum
is

insufficient
to
draw

the
blow

by
flow

through
the
valve

and
its
flow

goes

through
the

In
