Tire
Care
To enjoy maximum service from your tires, keep
them inflated to the pressures recommended on
page
46.
Regular Corvette tires should not be used for ex
treme vehicle operation. Special purpose tires are
available,
if needed, from major tire manufacturers. DRAINING
AND FILLING
THE COOLING SYSTEM
I. Open the drain cock at the bottom of the
radiator.
2. Remove the drain plug located on each side of the engine block just above the oil pan and be· hind the spark plug wire shields. 3. Replace the engine drain plugs and close the
radiator drain cock before refilling the radiator.
4.
To refill , add coolant until supply tank remains
one -half full. Then start engine and add coolant as necessary to maintain normal one-half- full level in supply tank. Recheck when cool and fill to
normal level.
Rotate tires
as shown every
6000 miles to distribute wear
. over all five tires. This will help you to obtain maxi
mum service from your tires.
(E) If the car will start but sta lls w h e n hot or has a roug h idle, you can sus pect a f aulty IDLE ADJUSTMENT, a malfunctioning AUTOMATIC CHOKE or an extremely
dirty and blocked AIR CLEANER ELEMENT. Clean
your air cleaner element if necessary. If the above Fuel Syste m checks and the checks suggested under the Electr ica l System followi ng do not corre ct the malfunction , i t is recommended that you turTI to your Authorized Chevrolet Dealer for further checks, adjust
ments or repairs.
ELECTRICAL SYSTEM If, when the ignition key is turned to "Star t," the engine
will not turn over, you have good reason to sus pec t elec
trical trouble.
(F) '
Vhen there is
no response at all to attempts to star t
the car , check the obv ious-your AUTOMATIC TRANS· M ISSION SELECTOR LEVER mus t be in Neutral or Park position befor e the engine can be started. Turning
the IGNITION SvVITCH rapidly back and forth several
times will sometimes correct a poor internal switch contact.
(G) The BATTER Y may be discha rged. If so, lights will
be dim and the horn will have a poor tone if it will blow a t
all. Usually a
garage recharge will be nece ssary to return the battery to operation. Occasiona lly, however, a p u sh start and long driv e will recharge the battery .
POOR BATTERY CONNECTIONS may be suspec ted if
th e car has operated prope rly a short time befor e and now not eve n the horn will operate. Check both ends o f both battery cables. If the connections are corroded, a car ma y
som etimes be restore d to operation by removing all cab le
e n ds, scraping all contacting surfaces clean with a pen
knife, and reassembling. If the cables a r e broken, they
must be replaced. The power supply should now b e restored
unless the battery is dead.
(H)
If, however, the lights and horn work properly but
th e starter will still not turn ove r , c heck the STARTER connections. A "click " from the starter soleno id indicates
th a t the wirin g to the starter is properly install ed. If the
wiring seems to be clean and tightly installed, the trouble
is proba bly in the starter itself and sho uld be referred to
your Authorized Chevr olet Dealer.
When the e ngine will "turn ove r " but will not start, [h e
foll owin g items may b e checked along with the Fuel Syst em
Checks listed previous ly.
(I) With a clean dry cloth wipe the ceramic portions o f
t he spark plugs dry. In particul arly damp or rainy weather dampness may be the cause of not starting, espec ially when the e ngin e is cold.
0) C heck the cables
at the top of the distributor and coil as well as eac h spark plug cable for tightness.
(K)
If the car w ill stilI not st art. ch eck for spark at the
spark plugs in th e foll owing manner:
Pull o n e of the spark plug wi res off its spark plug. Insert a
short piece of bare wir e (such as a bobby pin) between the
