YOU AND YOURCAR
AIDED BY RUSSELL
CIogging of Smaller Holes
in Block and Head May
Cause 0verheating.

It's paradox, but the faster cars
go the heavier their depreciation be-
comes.
With warmer weather a not too
distant expectation it may be well
to make note of one cause of over
heating not generally considered. If
your engine is misbehaving it would
be well to consider the possibility that
the smaller holes for water passage,
in both block and head, are partially
clogged. Often these holes need to be
reamed out, SO incrusted lis the rust
and scale. Since the water tends to
seek the easiest way from block to
head, and vice versa, there is less
circulation through the smaller holes
and thus tendency for the engine
to overhead at such points.
Holes Of varying sizes are used in
order to control circulation and to
provide more water where needed
To restrict the flow of water at such
points is going beyond the engineers
Cold Test at Home.
The hired girl was just a little sur
prised when she opened the refriger-
ator and found there a small can of
automobile lubricant, but milady had
a reason for putting the grease on
ice. 1t was a sample of some gear
lubricant which back ALLEY mechanic
had put unto the rear end of her
automobile under pretext of safe
guarding the gears against cold
weather. The gears having been
damaged the next step was to seek
proof that the lubricant wasn't what
it should have been. Providing a
handy test the refrigerator showed
that even in mildly cold weather the
lubricant would CONCEAL and teil to
provide proper protection for hard
working gears.
Next year, if there is any reason to
be doubtful of the efficiency of the
lubricant you have bought for the
cars Winter protection, just remember
the handy refrigerator test.
Overheats From Ice.

so likely to be prepared for engine
trouble Yet it is not uncommon for
ice to form over the radiator grille
in such way as to retard circulation
of air through the core. When this
occurs the engine overheatS, starves
for normally cool air. The remedy

Where automatic shutters are used
the ice must be broken off if the

Machanic Joe Speaking.
I'm checking for water leakage it
is surprising how many people over
look the engines side plates. These
are the plates which cover the blocks
water jackets. Radiator, pump and
hose connections often are blamed for
leakage which originates at these
plates.
Speaking of these plates reminds
me to suggest that if the car is going
into its third or more years of service

plates and scrape out rust and sedi-
ment manually. To try to dislodge
this scale by boiling out the block
may mean driving a lot of it into the
radiator"
Warns of Excess Ease.
In the opinion of one seasoned
motorist at least the modern car is
entirely too easy to operate. He be-
lieves that ease of operation is one
of the signs of approaching deca-
dence in civilized races, and makes
the interesting observation that if
cars were harder to drive there would
be fewer accidents. He dips into
history to support his theory that
nothing is ever really worth while
unless there are difficulties in the path
of its accomplishment.
Theory Can Be Proved.
This view is more than belief
grounded in the knowledge that the
Roman and other erstWhile virile
empires lapsed into decay because
of the abundant life. 1t is also based
on actual engineering tests. Several
