left rear side of the 6-cylinder block or at each side of the V.S block.
The radiator of your car is filled with "permanent" type anti.freeze

ENGINE LUBRICATION
After the first 1000 miles
of
driving, the original light body, heavy
duty, oil should be drained from the engine and the crankcase refilled
with oil as recommended on page 25. Every 2000 miles thereafter,
under normal operating conditions, drain and refill the engine in the
same manner. Adverse driving conditions may make it necessary to
change the oil more frequently. Where the car is very seldom driven,
seasonal changes may be satisfactory. Check oil level on the dipstick
regularly.
If
your Chevrolet is equipped with on oil filter, replace the filter
element after the first 1000 miles and every 6000 miles thereafter.
Again, adverse driving conditions may make more frequent changes
necessary.
TYPES OF OIL
Engine oils were formerly classified as Regular, Premium and Heavy
Duty types. These terms have been replaced by the designations "For
Service ML", "For Service
/I/INI"
and "For Service MS or DG".
For maximum driving protection under all driving conditions it is recom-
mended that you use oils designated "For Service MS" or "For Service
DG" in your Chevrolet.
