Every 4000 miles thereafter, under normal operating
conditions, drain and refill the crankcase in the same
manner.
Adverse driving conditions;
such
as extreme
dust conditions or short trip winter driving (less than
1,000 miles per month) makes it advisable to change
oil every month. Similar short trip driving in the
sum
~
mer makes
it
advisable to change oil every two months.
For maximum protection under all driving
conditions,
it is recommended that you use oil designated "For
Service MS" or
"For
Service DG" in your
Corvair.
Check the oil level on the dipstick frequently. The
level should be somewhere between the "add oil" and
"full" marks on the dipstick. Do not overfill. The oil filter
element should be changed after the first 5000 miles of
driving and every 4000 miles thereafter, more often
under adverse driving conditions.

COOLING SYSTEM CARE
The Corvair engine, being an air cooled engine, is
entirely dependent on the fan belt and blower to
supply
sufficient
volume of air for cooling
purposes.
The
engine
fan belt
should
be checked for tightness at regular
intervals and
replaced
when necessary. Watch the
"Temp~Press"
and
"Gen~Fan"
indicator lights on the
instrument panel for signs of possible engine overheating.
The engine air inlet
louvers
are located in each side
of the car just above the rear wheels. Since these louvers
supply all of the
engine
combustion and cooling air, care
should be taken
that
they are
never sealed or blocked.
