g Liquid Level
The radiator filler cap is also located under the hood at
the left, for convenience in checking the liquid level when
checking the oil. The level should be checked at least once
every week or ten days.
Ordinarily, only water needs to be added at these times,
although, if any considerable quantity is required during cold
weather, the strength of the anti-freeze solution should be
tested.
When the cooling system is drained and refilled, it is
necessary to use anti-rust solutions in summer and anti-
freeze in winter. The correct solutions for these purposes
are discussed on page 55.
Caution—When removing the filler cap from a hot
engine, rotate the cap toward the left until the stop is
reached. This is the vented position, which allows
steam to escape.
Keep in this position
until the pressure in the
system has been re-
lieved, then turn more
forcibly to the left to
remove. Turn the cap
all the way to the right
when reinstalling.

ire Pressure
The tire pressure is the fourth item requiring frequent
attention. All tires, including spares, should be checked
every week or ten days,* and maintained at the correct
pressure of 26 pounds minimum.
»
Check the pressure when the tires are cold, preferably in
the morning, and never after a fast run) Heat developed on
fast runs or from hot pavements increases the pressures and
they decrease again when the tires cool/>
Frequent checking is essential with low pressure tires,
as variations of only a few pounds make an appreciable
difference in riding qualities and tire wear.
If your spare tire is concealed in the rear compartment,
always unlock the lid and have the attendant check the spare
while he is checking the others.
The procedure for changing wheels when a tire is fiat is
given on page 62. •'.
The regular attention required by your LaSalle car,
in addition to the four topics just covered, includes lubr'u
cation at 1,000 mile intervals and a few items of general
care, all of which are explained on pages 41 to 47. Read
these pages before your car has traveled 1,000 miles.
*When touring and covering several hundred miles a day, check the tire
pressure every day or two.
