So many people use alcohol as
warning as to wood alcohol will
not be amiSS. Wood alcohol. also
known as methyl alcohol or
methanol, is real poison. 1t is
dangerous to the human system,
particularly the eyes, when in
hailed as a vapor or absorbed
through the skin. Worse still it
has an accumulative effect, the
body accommodating and retaining
the poison. 1t can generally be
told from denatured alcohol
(which is denatured ethyl alcohol,
treated to render il useless as a
beverage) by the sense of smell.
If wood alcohol should be used,
precautions should be taken to see
that the vaporS are not inhaled
or that the fluid does not come
into contact with the skin. In
some States users are protected
by statutes, which require han
ding in such a way that the user
is informed that he is getting
wood alcohol and is instructed
how to handle it.
Does Not Boil or Evaporate.
Manufacturers of glycerin de-
clare that this preparation will
neither boil nor evaporate and
that the solution can be placed in
the radiator while the weather is
still warm so that the car can be
protected against cold weather's
sudden setting in. This method
of preventing radiator freezing
costs more quart by quart than
volatile anti-freeze preparations,
but Is said to have it's eco
nQmical advantages because of it's
non-evaporating qualities. For

GIycerin Radiator Proportions.
Where exact radiator capacities
cannot be determined, the follow
ing table of proportions should be
used: To protect to plus 10 de-
greeS Fahrenheit, one part water
to every one and one-quarter
parts radiator glycerin; to pro-
tect to zero Fahrenheit, one part
water to every two and one-quar-
ter parts radiator glycerin; to
minus 10 degrees Fahrenheit, che
part water to every four and one
half parts radiator glycerin; to
minus Is degrees Fahrenheit, one
part water to every six and one
half parts radiator glycerin; to
minus 20 degrees, one part water
to every 10 quarts radiator
glycerin, and to minus 80 degrees,
use radiator glycerin without
dilution.
A Summer season of hard driv-
ing usually takes it's toll in over
heated engines due to clogged
cooling systems. Water contain
ing all sorts of minerals and i'm
puritieS are sometimes used, and
these impurities, including al
kalieS, not only eat the interior of
tack the radiator and interior of
the water jacketing of the engine
as well. This results in the for
nation of hardened residue and
rust. To assist the owner in con-
ditioning the cooling system of
his car, one of the service bureaus
offers these suggestions:
Prior Needs Outlined.
: I'm anticipating the extra de-
mandS on the engine in Winter
driving, the cooling system should
be properly conditioned. The first
step Is to drain all water from the
cooling system. Then fill with
system has been filled to capacity,
open the drain cocks, permitting
clean hydrant water to run
through the system for 10 or Is
minutes with the engine running.
ITO remove scale and Sludge
formation, use good radiator
cleansing compound, preferably
one recommended by the radiator
manufacturer, simply following
the instructions on the container.
Some kind of neutraliZing powder
should be placed in the radiator
after it has been flushed and
refilled to prevent corrosion. Most
authorized distributors and deal
ers have special information in
this connection.
"Once the system has been
cleaned, it is desirable to replace
both radiator hose with new ones.
While the outside of the old hose
may appear in perfect shape. the
interior is nearly always eaten
away by the action of minerals in
the water, plus the natural wear
and tear from the circulation of
hot water containing rust and
alkalieS. These deposits restrict
the flow of water and often cause
the engine to run hot.
1.-THE pump should be checked
for leaks, and the packing re-
placed if necessary by a compe-
tent mechanic. Finally, to COM
plete the job of checking the
water cooling system, the fan belt
should be adjusted or replaced if
necessary"
