Formula Suggested to
Take Care Of
Radiators

This is the season of the freeze pre-
ventive formula. The nip in the air is
followed by real frost, and then the car
that stands overnight in a heatless
garage or which remains out of doors
for long stretches with the engine quiet
needs protection against the elements.
Information on this timely topic is con-
tanned in a recent article in "Automo-
bile Dealer and Repairer."
There are three effective safeguard
ing methods. These are either to use
an anti-freezing solution, drain the cir
cuating system or garage the machine
in a heated building. The last named.
however, will require care when the
car is left on the street for any great
length of time and when the tempera-
ture is we'll belowfreezing. The empty.
ing of the radiator, etc, is favored
by many, but one must be sure that all
water is removed
The first method given, the use Of an
anti-freezing solution, is, perhaps the
best for all-around purposes, although
there are some who do not favor ITS
use. Calcium chloride, alcohol and
plycerine are non-freezing elements.
In using calcium chloride the CONNER
cial form should be avoided, as 1t con-
tains acid. Crystallized calcium chic
ride contains about so per cent water
of crvstallization and dissolves IN
about half it's weight in cold water;
consequently, eight pounds dissolved IN
one-half gallon of water will obtain
one -allon of the saturated ISOLATION.
The alcohol solution is favored by
manv because it is easily obtained and
prenared An alcohol solution may be
made with either wood or denatured
alcohol. the latter being alcohol that
is made unfit to drink by an admlxture
of certain substances.
/ Alcohol and glycerine is combina--
ton that is liked by some because OF
the low boiling point of the latter. The
disadvantage of using glvcerine Is that
il attacks the rubber hose of the cir
cuating system, causing the plies OF
fabric to disintegrate. Another factor
mitigating against its use is the cost.
Whenever used, it generally means re-
newing the hose in the spring.
In the use of calcium chloride, and
when employing other than the chemi-
cally pure article, one must guard
against the action of acid. This may
be neutralized by gradually adding
ammonia or soda ash until blue litmus
paper no longer turns red when dipped
IN the solution. Litmus paper indi-
Gates il acid be present.
With the alcohol solution one must
expect It to give off an odor when
heated and to boil readily when the
thermometer registers above the freez-
ing mark, or in mild weather. Be-
cause of these factors and the ten
dency Of the alcohol to evaporate
readily, thus lowering the freezing
point of the fluid, many object u
the solution. If one employs alcohol
it is advisable TO purchase and use a
hydrometer graduated TO read below
1000 These instruments are some
times termed promoters. They in
dictate to the user the strength of the
solution which should be maintained
according to the requirements Of the
locality.
Cleansing the Radiator
II is we'll to avoid the practice of
using any aiti-freezing solution until
the radiator and other components of
the cooling system are inspected for
leaks, for the alcohol will escape
through openings where water will
not pass. Il is also important that
all fur" scale or other deposits be
displaced from the radiator, matter
generally deposited through the use
of hard water.
