Nj. E., In Leslie's Weekly.
If car is kept in heated garage
no difficulty will be experienced in
winter starting. for the interior of
the cylinders and the cooling water
will be kept at summer Temperature.
Starting conditions in cold garage
are different, however, and It must
be remembered that excessive amounts
OF gasoline are required for the warm.
Ing up process which seems to be so
necessary before an engine can be
expected to develop its normal power.
Drain Radiator.
From the standpoint of efficiency
rather than convenience. the best way
Is to drain the radiator on cold nights
and to fill the cooling system with
warm water when the car is to be used.
This then places the entire engine in
the same condition, as regards temper

for fifteen or twenty minutes. and will
save the amount of gasoline which
would otherwise be required to bring
the entire system to this temperature.
1t will save dilution of the crank case
oil, and through the ease of starting
which Is thus assured will save the
severe strain on the battery which cold
weather usually entails. The battery
IS an expensive necessity of car opera

starter before the motor will re-

Radiator covers, robes and the like
will serve to retain the heat of water
cooled car for several hours. Cars
which are kept standing idle on the
street or in garages for more than
three or four hours, however, in ex-
ceedingly cold weather should be pro-
vided with some form of anti-freezing
mixture in the radiator. A 25 per
cent solution of alcohol (one-quarter
alcohol and three-guarters water) will
freeze at zero, 80 per cent solution
will freeze at five degrees below and
40 per cent solution will freeze at
twenty degrees below.
GIycerin Can Be Used.
II should be remembered that the
boiling point of alcohol Is much lower
than that of water and consequently
this proportion of alcohol will be re-
duced rapidly as car Is operated.
Glycerin may prevent this exapora-
tion to a certain extent, but one manu-
facturer recommends the following
anti-freezing solution: Alcohol 20 per
cent, glycerin, 20 per cent and water GO
per cent, thus giving nonfreezing
insurance to the point of twenty de-
grees below zero. Proportions of 16,
16 and 6S. respectively, will prevent
freezing to points within five degrees
below zero.
