~ANTi-FREEzE MIXTURE

An anti-freeze solution is a sub,
stance that has a low freezing point
but in using such a solution n must
be sure that it also has q boiling point
as nearly as possible to that of water
PIP degrees f. While the solution
may prevent freezing, if it is Of the
wrong sort it may also cause overhead,
ing on a moderately cold day. Any
salt, ordinary table salt for example
may be dissolved in water and used as
an anti-freeze, but / would advise
against the use of ordinary salt unless
it gives the desired freezing point and
also is free from any acid. Certain
commercial salts may produce an cleo
trolytic action in the cooling system,
and while this action may be slight, 1t
may cause serious damage, especially
to the radiator. Some experimenters
have stated that the action is too slight
to bother with, but why use a solution
with any action when it is possible to
get solutions that have no detrimental
effect.
Calcium chloride is commonly used
in solution with water because OF its
low freezing point. The commercial
salt is usually acid in action. hence IT
it remains in the cooling system all
winter there will be some bad results.
Instead of the commercial salt, pre-
bdIeu COl1ptu1uo u Ihc Gu1h ouSht -
be used. Many Of the compounds sold
in packages contain this salt, some of
the mod not. At any rate, the pre-
pared compound is supposed to be neu-
trail in action and therefore is safer to
use than salts you might get. The low
cost of salts inclines the owner to use
too little in solution, with the result
that the freezing point is correct only
for ordinary days. If a very cold day

freeze.
Alcohol Solution Best
A number of years ago, before we
used salt solutions commonly, motor
lists in general used alcohol and glycer-
inc combinations. These are best, as
is alcohol alone. The difficulty with
any alcohol mixture is that the alcohol
evaporates rapidly and one must have
made-up solution or plain alcohol to
add. So far as it's efficacy is con-
cerned, there is no questioning alcohol.
or the alcohol -glycerine mixture. The
latter is better than wood or dena-
tured alcohol alone, as the glycerlne
content tends to prevent evaporation
of the alcohol. Another advantage of
this mixture is that it may be made
any where. 1t is more expensive than
prepared compounds considering not
only initial charge but replacement as
well.
In the same class with home made
alcohol base mixtures are those mix
lures which may be purchased made-up
at the automobile supply store. These
are very effective and in some cases
are practically the same as solutions
one would make up using alcohol as a
base.
Some motorists have little or no con
ception of economy in car operation,
and this class will attempt to use any
old liquid or salt that someone says
won't freeze. Old engine oil has been
suggested. and a lot of waste products
that do not cost much.
Kerosene has been used as an anti
freezing solution. When kerosene is
used in place of water the cooling sFs-
tenn is protected from freezing, but
the engine is likely to overhead on a
moderately cold day. The odor about
the car is not what is to be desired,
but therwise kerosene is satisfactory.
