Two Popular Anti Freezing Sub
stances vii Prevent Serious
Damage In Winter.
CALCIUM CHLORIDE IS CHEAP
u Should Be Carefully Tested as Il
Frequently Contains impurities
and Free Aolds-Alcohol 10
Somewhat Expensive.

iheTe are w popular N easily
obtained a~ntlfreezing substances
which when used In proper proper
ions Will prevent the radiator con-
'ents from suffering damage during
.old weather, according to Ernest
Coler In Motor Life. The trst OF these
s calcium chloride, the other alcohol.
Calcium chloride comes In the form
,f a salt, and is sold under It's W
1nme as well as under various pro-
prietary names which usually Indicate
is freeze-proofing quality. When pur.
chased In the open market calcium
chloride is cheapest as well as most
uncertain; II should be tested care
fully. since II frequently contains I'M
purities and free acids which attack
aluminium ms well MS the metal and
solder OF radiators. Blue lltmus paper,
when moistened with n calcium chic
ride solution containing acids will
turn pink. The salt may be neutrallzed
by the addition of soda ash or am
monia until the litmus paper no longer
turns pink.
Amount TO Use.
The amount of calcium chloride 10
be used in the cooling system depends
on the temperatures likely TO be en-
countered and the capacity OF the
radiator. Two pounds OF calcium
chloride added to each gallon Of wa
ter Will keep the mixture from
freezing Mt temperatures not lower
than 10 degrees Fahrenheit. Three
pounds per gallon will withstand n
temperature as low as two and n half
degrees Fahrenheit. Four pounds OF
calcium chloride In each gallon of wa
ter will not freeze at 10 degrees below
zero.
The calcium chloride should be dis
solved In hot water, and care should
be exercised that non OF the mixture
Is spilled over the radiator or other
parts on which Il is apt to leave n
somewhat unsightly white deposit.
Whatever II lost of the mixture by
evaporation should be replenished
from a saturated solution of calcium
chloride In water. Such saturated So
luton Is made up by adding the salt
to hot water until the liquid refuses
to dissolve more Of the salt and n
layer Of undissolved calcium chloride
remains at the bottom of the container.
Cleaning Essential.
A point of great importance "a 10
clean the radiator thoroughly before
rendering It freeze-proof with calcium
chloride solution. This cleaning is
perhaps most competently done by one
Of the radiator cleaning compounds
sold by dealers. The cleaning Itself
serves a twofold purpose. II frees the
radiator from accumulated rust, scale
and dirt, and incidentally is apt tc
open tiny leaks which previous to the
cleaning were kept closed by dirt. II
the cleaning were neglected the cal
!, cium chloride solution would oper
these small leaks in short order, tn,
solution, leaking out, would render tn,
spot unsightly, and a certain chemica
action would be set up at the mixture'
, exit. All this Is avoided, however, 4
the radiator Is cleaned out and al
leaks are repaired before the COOLING
: system is filled with antifreezing solu
! ton.
: Denatured alcohol, enjoys well-de
. served popularity with motorists VIII,
: during cold weather render their radla
tors and engine Jackets immune L
!, damage by adding alcohol to the wa
ter. The advantages Of alcohol ar
, that It does not have any destructiv,
. action on rubber connections or oil
, metal, that 1t will not form deposit
. Of foreign matter and produces n
: electrolyt!c effects. The drawbacks o
! alcoholic they may be called such
: are. that It is somewhat expensive
. and that II boils at lower temperature
than water, and must therefore be re
, plenished from time to time.
