E)
Coolant Level: Have the coolant level checked
during each stop at the gasoline station. Add
water to bring level to about 11,4 ' below the
bottom of the filler neck. Overfilling will dilute
the anti ·freeze and also result in coolant loss
through the overflow tube. CAUTION : Driving
In heavy traffic, at high altitudes, or in very
hot weather may build up pressure in the
cooling system. When removing the cap place
a cloth over the cap, turn left to first stop,
allowing steam to escape through overflow
tube, then remove cap.
Thermostat Your new car is equipped with
180 degree thermostat for use with perma·
nenl-type anti-freeze.
If
you later prefer an
lcohol type anti-freeze use only a 160 degree
thormoslat.
Manifold Heal Control Valve_ A cold engine
will warm up faster and accelerate more
moothly if the valve that controls heat flow
In the mani fold works freely. It is normal for
I d deposits to accumulate in time on the
y lve shaft causing it to tighten up'. Manifold
II t Control Valve Solvent, available from
your dealer, should be applied at six month
lnt Iva Is. Slide shaft in and out and rotate a
, w times to distribute the solvent. Apply
only when manifold is cool.
The Carburetor Air Filter. The special easy
to change fire-resistant filter installed in your
carburetor should be cleaned and inspected
every 6 months and replaced once every two
years, to assure good fuel economy. Clean or
replace more often when car is driven in
dusty or sandy areas. Replace filter if dam-
aged. DO NOT wash or oil. Simply remove
the metal container, unscrew the wing nut
and lift out filter. Clean with compressed air,
holding nozzle about two inches from filter.
Fuel Filter. Your new car has a filter in the
fuel tank to prevent water and foreign mate-
rial from entering the fuel system. There is
also a fuel filter in the fuel line at the fuel
pump outlet. If this filter is plugged it can
limit car speed and cause hard starling.
Under normal operating conditions the filter
should be changed at 20,000 mile intervals,
or every two years.
011 Cap Filler. The cap on the oil filler tube
is a combination ventilator and permanent
filter. The filter inside the cap should be kept
clean to allow clean air to remove combustion
products from the crankcase. To clean the
filter wash th e entire cap periodically in kero-
sene and rel ubricate with SAE 30 engine oil.
ENGINE PERFORMANCE EVALUATION
Engine operation efficiency depends on cor-
rect ignition, carburetor adjustments, and on
valve lash where applicable. To obtain best
engine performance, Chrysler Corporation
recommends that the engine be evaluated
every 10,000 miles and tuned, if necessary.
Services performed during this evaluation
should include the following :
SPARK PLUGS-Remove and inspect each
spark plug. Most plugs can be cleaned,
adjusted, and reinstalled. Rough idle, hard
starling, frequent engine miss at high speeds,
or apparent physical deterioration, are indica-
tions that the spark plugs should be replaced.
DISTRIBUTOR-Clean and inspect the dis·
tributor cap and rotor if required (wash cap
in household detergent and water solution).
Check breaker points for abnormal pitting.
distributor secondary wires and tower caps
are clean and connected properly. See that
ignition timing is set to vehicle specifications.
CARBURETOR- Remove and clean air filter.
Check operation of manifold heat control
valve and choke diaphragms, use solvent
recommended. Clean crankcase ventilator
system. Check and adjust choke fast-idle cam
and fuel mixture.
BATTERY-Check specific gravity. Clean and
tighten terminals; apply grease to post and
terminals. Check circuit voltages.
