Z itself serves a tWotold purpose II
I frees the radiator from accumulated

Z Is apt 70 open tiny leaks which pre-
/ vicus to the cleaning were kept
] closed by dirt If the cleaning were
] neglected the calcium chloride solu-
I ton would open these small leaks IN
I short order, the solution, leaking out
would render the spot unsightly ana
I a certain chemical action would be
set up at the mixtures exit All this
Z IS avoided, however, II the radiator

filled with anti-freezing solution
Alcohol Is Valuable.
Denatured alcohol enjoys we'll
deserved popularity with motorists
who during cold weather render their
radiators and engine jackets immune
TO damage by adding alcohol to the
water. The advantages OF alcohol are
that &c does not have any destructive
action on rubber connections or on
metal that il viii not form deposits
OF foreign matter and produce no
electrolytic effects The drawbacks
sucl-are. that It Is somewhat eL-
pensive, and that II boils at lower
temperatures than water and must
therefore be replentshed from time TO
time.
when denatured alcohol is added 20
the water, a 10 per cent solution
made by including a little over three /
quarters Of a pint Of alcohol in each {
gallon Of water-Wiu Withstand g !
tempera ture Of IS degrees above zero ]
+. A. IS per cent solution-one quart 4
OF alcohol IN each gallon Of solution /
will Withstand a temperature Of I
zero; and 40 per cent solution
three and a quarter pints OF alcohol /
per gallon OF mixture-Wiu give per /
feet safety at % degrees below. In /
general. a Is per cent solution wiz
be found sufficient The easiest way /
to secure this mixture Is to iii the
radiator from a quart container, Civ
ing quart OF alcohol for every three
quarts Of water
While Elycerine alone makes a
rather expensive and odOriferous anti
freezing mixture. when glycerine Is
used in limited quantities and in
combination with alcohol and when
the slight drawback OF its being in
.urious to rubber connections is left
1nConsidered. a mixture for tempera- n
lures not lower than five degrees
above zero is made up by compound
ng mixture which In each gallon
contains one and one-uuarter pints OF
slycerine and one and one-quarter
