Sounds Like Loose Wheel.
Some of the perplexing noises
heard in the rear end OF any car
are likely to be due to a loose rear
wheel. There is nothing alarming
in this. In fact, rear wheel can
be loose enough to cause consider
able noise yet there is no danger OF
it coming off. Rear wheels are drawn
up on tapered axle end Thus if the
wheel slips just a little on the axle
it will do SO with a loud cracking
noise which at times will sound like
a decided crack as of something
breaking When looseness occurs
simply have the service man tighten
the wheel. A large wrench is needed
for this purpose, not to mention ell
bow grease.
Watch Your Reasoning
Safe driving today is a matter of
constant concentration on the sub
ject and of having your wits about
you. The other day found myself
trying to pass city bus on the
right. Subconsciously I thought OF
1T as street car on tracks.
Overtaking another car on the
highway may seem simple and safe
enough il there is a second car a
reasonable distance ahead of it. But
there is hidden danger. Ever pass
one car and nave the second one
suddenly slow down, thus cutting
down space needed to cut back into
line?
He Who Laughs Last.
A friend OF mine tells the true
story of his first ride in the family
car. Upon returning nome from a
l0-mile "trip" the agent tor the car
was astounded to find that the
owner had driven the entire way in
second gear, finding second fast
enough Today this seems ludl-
crous. but aren't many of us doing
just about the same thing when We
stay in high gear for very low specs
and find it quite slow enough?
Shouldn't we. too, make better use
of the transmission by shifting to
second or low when in the very low
speed range or when upgrades are
steep. The car may run all righ
in high, yet this may not be best
for It.

@ My service man tells me the;
the cylinder head of my cars en-
rrir ic ha DIV, clyaI thot will
have to replace it Immediately. He
believes that the engine must have
overheated, but I do not recall hav-
ing had such trouble as the engine
always has been cool running What
could have caused the crack?-E.
T. N.
A. This was probably caused BY
adding cold water to the engine
when it was hot.
@. In putting last winters suppl;
of anti-freeze in jugs I noticed tha'
the fluid smelled of gas. You might
think l had drained off the crank
case rather than the cooling sys-
TEN. Is this normal, or does il
mean that something is Wrong?-
S. S. V.
A. Any loose cylinder head joint
will allow leakage of exhaust gas
into the cooling system. This con-
teammates the coolant and gives
the smell of exhaust gas. This alone
isn't an objection. But the pres
ence of exhaust gas with the anti
freeze chemicals means that the
cooling system is becoming a chem
lcal factory. Some undesirable acids
also are present. That is why it
doesn't pay to save anti-freeze from
one year to the next.
Q. The instruction book calls for
use of fairly light engine oil even
in summer I wonder if I would
be getting better oil mileage if I
used heavier grade of oil, espe-
cially on trips-L. L. S.
A. Tests have shown that lighter
oils give better results on the road
than in loW-Speed city driving. This
Is due to the fact that they operate
at lower temperature. flowing more
freely and giving up their heat more
readily when returned to the crank
case.
