Plugs Need Change
Every '10,000, Miles
A spark plug. may look
good to the casiial observer
after 15,000, 20,000'or even
30,000 miles.
So why change plugs
after 10,000miles of use
in your family "car?
There's a .. good reason
according •to experts. 'The
10,000 mile change recom-
mendation is not actually
based on the tact that
spark plugs are "worn out"_
in the strictest sense after
10,000 miles of service.
This figure — selected
after extensive spark plug
life tests = merely repre-
sents a safety factor be-
yond which plugs may
misfire under the sudden
demands of peak acceler-
ation or extremely heavy
load.
Gas Economy Drops
It also represents the
poirit at which gas econ-
omy begins to drop. In
addition, the car is harder
to :start, power is lost .in • ..
passing.
A spark plug is con-
sidered worn out when it
reaches the point where it
is likely to misfire —; re-
gardless bf its appearance.
And, contrary to' popular
opinion, misfiring doesn't
necessarily mean the plug
didn't create a spark. It
means simply that the
plug failed to. ignite the
gasoline properly—wheth•-
er a spark was produced
or nbt!
A new spark plug with
the correct gapsetting
needs about 5,'000 volts to
fire. However, asthe plg
remains in service, co -
stant heat and chemical
attack .plus electrical ero-
sion cause the gap to be-
come -wider, thus increas-
ing the amount of,voltage
.to fire the plug.
Gap Gets Wider
Spark -plug gap growth
occurs at a rate of .about'
.001 inch for each 1,000
miles of driving. Conse-
quently, a set of plugs that
has 'been in° service for .
10,000 miles generally will
have gaps that are about
,010 inch wider than the
original 'settings an°d
higher voltage is needed•
to make 'them spark.
And, this is only ' for
normal °driving. Operating
the engine . at very high
speed can decrease , the
amount of coil voltage
available to fire the spark
plugs by 30 to 40 percent!
Accelerating to passon a
.highway may practically
double the voltage. burden
on the spark plug.
•
Needs More Voltage
That's why misfiring is
first noticed while accel-
erating because it's here
that the plugs actually
can require more voL age
to produce a spark than
the ignition system is ca-
pable of producing — es-
pecially if the plugs are
badly worn.
Remember, as plugs re-
main in service, more volt-
' age is needed to make
them spark. As the ignition
system ages, its ability
to produce high voltage
lessens. If the point is
reached where the 'spark
plugs require more voltage
i to spark than the system
can produce, the spark
plugs misfire,:
Changing spark plugs at
10,000 mile intervals' pre-
vents this from.happening..

Guess Again -Universal Joint.„,a
Is Nota .United Nations Bar
If your favorite service
mechanic tells you that
you need a universal joint,
he's not inviting you to
invest in a bar near the
United Nations building.
He's telling you that a
critical parte of your car''s
drive shaft needsreplace-
inent. '
There are a number of
common automobile seri-
ice terms that could be
confusing, if you don't
talk the language. The
Americb,n Petroleum In-
stitute provides a. 'iort
dictionary of those terms.

BAD SHOCKS --
Your mother-in-law
is comings .- -
Shock absorbers im-
prove the riding comfort
bysoftening the impact
of bumps in the road. For
safety, shocksshould be
checked for damage, wear
or fluid leaks.

KING PINS —
Ronal brooches.
Not really. They're met-
al rods which allow your-
front
ourfront wheels to pivot when
you make a turn. If they're
worn, get them fixed; it's
dangerous.
* * *
FRONT END WOBBLE —
A go-go dancer.
Wrong again —' it's ' a
vibration caused by worn
parts of the steering
mechanism, wheels that
are out of line fromhit-
ting bumps, or worn king
pins ... and it should be
corrected immediately.

WORN SHOES
Hippie sandals.
It's brake shoes they're
talking about. When you,
step on the brake pedal
the shoes are hydrauli'=
cally forced against the
brake drums, causing the
car to slow down. Improp-
erly adjusted shoes may
cause premature wear and
damage to the brake drum.

FILTER —
The end .of a cigarette.
There are three filters
on your car. One helps
keep dirt" out of the air
entering the carburetor,
another purifies the ,oil
circulating in the .crank-
case, and a third traps
.sediment from the . gaso-
line ' before it' enters your
'carburetor. These filters
need periodic cleaning or
changing. v

CATALYTIC MUFFLER —
An exotic fur neckpiece:
Nope. Catalytic mufflers
are pollution control de-
vices currently designed to
reduce certain exhaust
emissions. Basically, they
chemically "purify" the
gases left after. the fuel
has burned.

PLUGGED PCV —
An assassinated foreign
dignitary.
Misse'd again. The Posi-
tive Crankcase Ventilation
valve is a pollution control
device designed td help cut
down . on emissions into
the air we breathe. When
it isn't checked regularly,
it could hamper your car's
performance.

DIRTY LIFTERS —
Sneaky thieves.
When sludge accumu-
lates on the valve lifters,
the valves can't do their
job, and grit and other
contaminants get into the
finely machined parts of
the engine, causing wear.
A clogged oil line maybe
the culprit.
Fun with Signs
International -type road signs, indications• that give
their messages in • pictures not words,. are beeoming
more popular on this continent. It doesn't take much
of a humorous flight. of fancy to read things into these
• signs that may not have been their original intent.
For instance, thc.se signs might -he saying:
A. Get a Horse! E. Dry`Ma.rtinis Ahead
B.. Unorthodox Chureh F. ,No Red Cars Allowed,.
Ahead G. The Natives Aren't
C. Ban Half the Bomhs • Friendly
U. Gas Station Ahead,, , H. High 'Winds, Watch

For what they aettially' mean, see below:
A. Horses Ahead
B. Traffic ,Entering from
Both Sides • G. "1'.wo-Way' Traflie

Safety Requires Check
Of Power. Steering
If your car is equipped
with poWer steering, you
may think that this sys-
tem is very complicated
and must be serviced by
highly skilled. technicians -
using costly special tools.
This is not the case.
Granted, a power steer-
ing system is considerably
more complex than a non-
power system. But most
power steering mainte-
nance can -be atcon plished
bys$the motorist .or his
service station operator.
Special tools are not' usu-
ally required.
At Heart is Pump
At the ' heart of your
car's power steering sys-
tem is- the power steer-
ing pump.. This hydraulic
pump merely supplies the
pressure to urn your car's
wheels ,whe you turn the
gine. If this belt should
break, your entire power
steering system will cease
to function, immediately.
This could be extremely.
dangerous if you are trav-
elling at high speed on.the
freeway.
Check Fluid teve1
While you are checking
• the fluid level and the
drive belts, check the hose's
that connect the pump to
- the other' components in
the system. Hose connec-
tions should be tight and
leak -free. Hoses should be
firm and free of cracks.
Leakage in the hoses of
the system is the main'
cause of fluid loss, 'which
in turn is the main cause
of power steering troubles.
'How can you tell if your
power steering systemt-
needs attention? Usually,
steering wheel. This punl,p the first sign is either an
unusual noise (squealing,
chattering or knocking
sound) or a change in the
"feel" of your steering
(sluggishness, jerkiness or
a tendency to pull to one
side) .
If .any of these symp-
toms occur, you should
waste no time in getting
your system checked; ear-
, ly attention can prevent
big problems later,
rarely breaks down as long
as yotPmake sure its sup-
ply of power steering fluid
does not get too low. Peri-
odic checking of the fluid
level is all that is neces-
sary for regular mainte-
nance of the power steer-
ing pump.
One other item that
should be checked period-
ically is the belt that con-
nects the pump to the en-
