when
engine is idling.
CAUTION: If either of these indicators light
while .
car is being. -driYen, immediately follow the
procedure outlined .vnder "EMERGENCY OPER­
ATING INSTRUCTIONS," so car may be driyen
to the nearest service facility.
BRAKE SYSTEM WARNING LIGHT
This dual purpose indicator light operates as
follows:
With parking brake applied the red light will light
when
the ignition switch is turned on.
As a dual service brake system warning, the red
light will come on when the brake pedal is depressed
if low pressure has developed in either the front or
rear brake system. Have your authorized Chevrolet
dealer locate and correct the trouble immediately.
EMERGENCY OPERATING INSTRUCTIONS
(To be followed if either
TEMP-PRESS or GEN-FAN indi­
cators
light while car is being
driven.)
1. Set heoter FAN and HEAT
controls to full "ON" positions.

(If equipped with air conditioning, turn air condi­
tioning
COOL switch to OFF.)
NOTE: After setting the heater controls, leave
them in that position until cause of trouble is
corrected.
2.
Stop the car a -s , soon as driving conditions permit.
furn ignition
key to OFF to stop engine but turn
key
back to·-PNso heoter blower will continue
to
cool engine.
3. Check for broken fan belt or belt off pulleys or
engine low oil level. If only GEN-FAN indicator
is lighted, belt is not broken or off pulleys and en­
gine oil level is satisfactory, car can be driven at
slow speeds; however, generator must be checked
and serviced as soon as possible.
4. If trouble is found to be a broken fan belt or belt
off pulleys, wait approximately five minutes, start
engine and drive car at no more than 25 miles per
hour until TEMP-PRESS indicator comes on, then
repeat Step 2.
NOTE: The GEN-FAN indicator will stay on until
fan
belt is installed.
5. Repeat Step 4 as necessary until facility is reached
where fan belt can be installed.

clean and reinsert it firmly for an accurate reading.
The oil level should be maintained in the safety margin,
neither going above the FULL line nor below the ADD
mark. Reseat the gauge firmly after taking the reading.
DO NOT OVERFilL.
COOLING SYSTEM CARE
The engine fan belt should be checked for tightness
at regular intervals. When a new belt is needed use only
the approved premium belt available from your Chev­
rolet dealer. If any other belt is installed, replace with
recommended belt when possible.
Watch the TEMP-PRESS and GEN-FAN indicators on the
instrument
panel for signs of overheating.
Air inlet louvers, located in the panel below the rear
window, supply air for engine combustion and cooling
and for the Direct Air Heater. Make sure the louvers are
never sealed or blocked.
TIRES
The factory installed tires on your car are selected
to provide the best all around tire performance for all
normal operation. When inflated as recommended in
the
tire inflation pressure table they have the load
carrying capacity to operate satisfactorily at all loads
up to and including the specified full rated load, at all
normal highway speeds.
RECOMMENDED TIRE INFLATION PRESSURES Pounds per Square I nch (Cool)
MODELS TIRE PLY
1 TO 6 PASSENGERS Standard
Coupe + 200 LBS. LUGGAGE 4-Ply Rating-2 Ply (1100 LBS. LOAD)

1 TO 5 PASSENGERS Monza Convertible -+ 200 LBS. LUGGAGE 4-Ply Rating-2 Ply (950 LBS. LOAD)
1. Tire inflation pressures
may increase as much as six (6) pounds per square
inch (PSI) when hot. 2. For continuous high speed operation (over 75 MPH) increase tire inflation pressures four (4) pounds per square inch over the recommended pressures up to a maximum of 32 pounds per square inch cool for 4-ply rating tires.
When the 4 psi pressure adjustment for sustained high speed with maximum vehicle load would require inflation pressures above the maximum allowable, speed must be limited to 75 miles per hour.

3. Cool tire inflation pressure: after vehicle has been inoperative for three (3)
hours or more or driven less than one (1) mile. Hot tire inflation pressure:
after vehicle has been driven ten (10) miles or more at 60-70 mph. 4. Vehicles with luggage racks do not have a load limit greater than specified. 5. When towi ng trai lers, the allowable passenger and cargo load must be reduced by an amount equal to the trailer tongue load on the trailer hitch.

Downloaded from www.Manualslib.com manuals search engine cup at the end of the spark plug
wire
and the tubular metal con­
nector inside of it. If the spark
plug wire is wet or oily, wipe it
dry.
Wrap a dry handkerchief or
facial tissue, folded several thick­
nesss, around the wire at least
three inches back from the end
and grasp wire at this point.
Hold the
bare wire about V4 inch
from the bare tip of the spark
plug from which you removed the
wire. When the engine is "turned Checking for Spork
over" a spark should jump across the V4 inch space, indicating
ample current supply.
If no spark jumps, the difflcultyis 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 checkd.
(L) Engine overheating will occur when the OIL LEVEL falls
dangerously low.
Check the oil level as a matter of course.
CAUTION: Never drive the car when 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 Checking Fan Be" Tension
bracket until the belt is tensioned properly, then retighten the
bracket bolts. Proper belt tension is such that, when belt is de­
flected downward with moderate thumb pressure at a point midway
between the
generator and fan pulleys, the belt will deflect about
:Va" to K6". Do not overtighten the belt.
(0) Another cause of engine overheating may be an inoperative
COOLING SYSTEM THERMOSTAT. If the thermostat should fail
in the closed position, it will not permit air to circulate through the
engine.
See your Authorized Chevrolet Dealer.
