cup at the end of the spark plug
wire and the tubular metal con-
nector inside of it. If t!'le spark
plug wire is wet or oily, wipe it
dry. Wrap a dry handkerchief or
facial tissue, folded several thick-
nesses, around the wire at least
three inches back from the end
and grasp wire at this point.
Hold the bare wire about
%
inch
from the bare tip of the spark
plug from which you removed the
wire.
When'
the engine is "turned

over'! a spark should jump across the

ample current supply. If no spark jumps, the difficulty is probably
caused by a defective ignition part and should be corrected by
your Authorized Chevrolet Dealer.
COOLING SYSTEM
When the car will run but evidences serious overheating on the
temperature gauge in the instrument panel, there are several items
which may be checked.
IL)
Engine overheating will occur when the OIL LEVEL falls danger-
ously low. Check the oil level as a matter of
course.
CAUTION: Never drive the car whep the
"Temp·Press"
indicator
in the instrument panel is lighted.
.. ..
1M) Check the air intake louvers. Clean them if they are plugged
with leaves or other foreign material.
IN) Condition of the FAN BELT
is very important, not only for en-
gine cooling but also for proper
generator operation. Check the
condition of the
belt.
Replace it
if it is worn or frayed. Loosen the
idler bracket bolts and move the
bracket toward the engine to
remove and replace the belt.
Tighten the belt, whether new or
old, by loosening the idler bracket
nuts, prying with a bar on the
Clteeking Fan 8e" Ten.lon
bracket until the belt is tensioned properly, then retighten the
bracket
bolts.
Proper belt tension is such that, when belt is deflected
downward with moderate thumb pressure at a point midway be-
.
tween the generator and fan pulleys, the belt will deflect about
%"
to 7 / 16". Do not overtighten the belt.
(0)
Another cause of engine overheating may be an inoperative
COOLING SYSTEM. If the cooling system door should fail to open,
it will not permit air to circulate through the engine. See your
Authorized Chevrolet Dealer.
