Radiator Protection.

Warning that frozen motors
annually cost car owners millions
of dollars, the American Automo-
bile Association declares that mo-
florists can save themselves heavy
repair bills and at the same time
divert approximately $50,000,000
into business channels by prepar-
ing their cars to withstand the
depredationS of Jack Frost.
The A. A. A. cites tabulationS OF
the United States Weather Bureau
to show that a downtrend of the
temperature may be expected
throughout the country within
the next three weeks, and, with
the possible exception of the eX-
IRENE South, it may be expected
to fall as much as 80 degrees.
Pointing out that more than
100000 motor vehicles are reg
iStered in the area where the
temperature falls the lowest, the
national motoring body says that
an average of three dollars spent
in preparing each of these for
cold weather would mean the eX-
with garages and service stations.
Repair Bills Saved.
cat the same time" says the
A. A. A., car owners would save
the annoyance and trouble result
| ing from frozen motors and bat
terieS. These usually follow in
the wake of sudden drops in the
temperature and often destroy
the mechanical efficiency of the
car, sometimes causing damage
beyond repair.
while anti-freeze preparations
form the basis of protecting the
car in Winter, they should not be
used until the automobile has
been made ready for the change
from Summer to Winter condi-
tons"
The A. A. A. outlines some of
the simple precautions that should
be taken as follows:
l. Have all rust and scale re-
moved from the engine jacket,
radiator and other parts of the
cooling system. This should eX-
tend to diSconnection of the hose
and complete cleansing with a
washing solution, preferably one
containing soda.
2. Tighten all parts of the cool
ing system. Careful attention
should be given to hose connec-
! lions, gaSketS, expansion plates,
drain cocks, pump packing and
grease cups or fittings on the
water pump. The radiator should
also be inspected for leaks.
8. Use anti-freeze solutions with
boiling points above that of water.
1t is desirable to use a solution
that will not boil out and leave
the motor unprotected.
The statement continues:
Do Not Put Off.
There is a tendency Of many
car owners to await the first re-
port of freezing weather and then
rush to the nearest filling station,
drain off some water, and fill the
radiator with an anti-freeze prep
aration. In the meantime, small
leaks have crept into the cooling
! system and passed unnoticed in
! the Summer. AS result, the
anti-freeze mixture, put in with
out an inspection of the cooling
system, soon evaporateS and sud-
denly the motoriSt is faced with
having his car engine freeze at a
time when the car is most needed.
THE Bureau of Standards,
which has been studying various
| types of anti-freeze solutions.
points out that where a glycerin
Cor glvcoD solution is used it is
essential that any leakage in the
cooling system be repaired to
avoid waste. The bureau also says
that there is no reason to believe
that distilled glycerin Cor glycoD
causes leaks except in so far as
It's solvent action, tending to
loosen scale, may uncover cracks
or holes in the metal.
Regardless of the type of anti
freeze used, the motoriSt should
avoid waste by having the level
of the liquid in the cooling sys-
/ tenn at least two inches below the
overflow to allow for thermal eX-
pansion."
