RULES FOR MAKING
STARTING EASIER IN
SHARP WINTER AIR
Liberty Service People Offer
Useful Information on Cold
Weather's Effect on Motor,
Carburetor and Oil.

Carburetor and Oil.
The service department of the Lib
erty Motor Car company recently pre-
pared some very helpful information
on the starting of cars in cold weather.
This was intended primarily for Lib
erty owners, but proved so applicable
to great many other cars that the
company has since made the informa
ton available for all motorists. Their
instructions follow:
There are three main reasons for
difficulty in starting the motor In cold
weather:
1. Poor gas mixture.
2. Reduced efficiency Of battery.
3. Stiff motor.
An intelligent understanding of the
changes brought about by lowered
temperature, on the carburetor, cleo
trical equipment and oil, will help
overcome your individual trouble.
THE cARBURETOR.
The functioning of the carburetor is
| to vaporize the liquid gas and mix 1t
| with an adequate proportion OF air,
which, under compression, constitutes
the explosive mixture. Heat and cold
have very definite influences on the
| CarDufetlOn OF INC llqulu 6aSoiihS.
Gasoline is a volatile liquid and
easily vaporized under the influence Of
heat, being less susceptible with
decrease in temperature. The gasoline
yapor is Just as easily reduced back
to LIQUID form under the influence of
| cold. Thus, cold thrush Of air
through the carburetor on an already
cold Get of gasoline. will result in 81
very weak mixture of air and gaso-
line vapor. Therefore, 1t follows, that
tho carburetor must be adjusted TO
give stronger or richer mixture when
starting the motor under cold weather
ELECTRICAL EQUIPMENT.
| The only part of the electrical
equipment influenced by the cold Is the
battery, which provides both the power
| to rotate the starter and the current
which induces spark at the plugs.
When called upon to rotate the motor
by means of the starter, the battery
sets free all it's stored up energy to
be used without restraint. However, q
battery, like everything else, has Its
limitations, and can only store up Just
so much energy. Furthermore, 1t is
true of an electric storage battery that
with a lowering of the temperature, Its
effectiveness decreases. so IL follows
that in cold weather the starter Is less
able to do it's work, because or de-
irving less power from the battery,
than under normal weather conditions.
OIL.
Heat causes oil to become thin and
flow easily Cold causes II to congeal
and become viscous or sticky. 1t Is
readily susceptible to either influence.
The moving parts of the motor are
covered with oil which becomes con-
gealed if the motor is left to stand ldie
at a low temperature. III II be cola
| enough, the motor will literally be
come frozen. And it is then, in cold
weather, that the starter is called upon
to perform it's work.
Iubricating oils are obtainable In
varying degrees of viscosity, or thick
ness, at normal temperatures, usually
termed arctic light, medium, ana
heavy grades, arctic being the thinner.
This arctic grade should be used dur
'"s FOR EASY STARTING.
It is obvious that warmth is desir-
able for starting the motor easily.
However. for those who must start
their motor cold, we suggest the foi-
lowing:
1. Equip the car with radiator and
hood Jacket.
Q. Put the following anti-freeze So
luton in the radiator.
"A mixture of dena tured alcohol and
glycerine in the following quantities.
for the Liberty: Alcohol, ! Id gar
Ions glycerine, II gallon; water, !
gallons
g. Take battery to charging sta
ton and have it charged and checked
over.
A. Have electrical equipment thor
oughly checked over and adjusted by a
nj fern hlV at an
| official service station-to ensure there
| is no wastage of current due to bad
| terminal connections and insulation.
| 8. Have carburetor adjusted al
service station to suit weather condi-
lions.
g. Drain oil from motor and trans
| mission and refill both with high
grade thin or arctic oil.
| Z. Carry In your car strip or wood
with which to prop open the clutch.
8. See that printing cup taps work
easily and freely.
9. Fill small oil can with gas and
keep it in a convenient place on the
car.
The above are general principles te
observe In putting your car in the
best condition for easy starting. Here
| are some further provisions to be OBJ
| served Mt the time you stop your car
| which will make it much easier to get
| the motor going again when you want
| to use II.
/ I. Before switching off motor, pull
down front flap on the radiator Jacket
2. Race the motor for few Sec
onds, then switch off, opening up the
throttle at the same time.
i 3. Push out clutch and prop oper
with suitable strip of wood before
motor Is switched.
4. II the motor has been left LONG
enough to become icy cold, squirt gas
oline into the printing cups before
cranlsing.
Do not waste all the current in thu
