on the wall of the carburetor air cleaner, should be cleaned
in solvent and reoiled with engine oil whenever the engine
oil is changed.
Positive crankcase ventilator valve
The positive crankcase ventilator valve should be replaced
every 12 months or 12,000 miles, whichever occurs first.
Crankcase vapors and other impurities can cause malfunctions
of the crankcase ventilator valve. Periodic replacement is
necessary for smooth engine operation and to insure efficient
functioning of the unit.
Fuel Alter
The fuel filter element should be replaced at least every spring
and fall. More frequent service is necessary under unusual
operating conditions. The filter element stops small dirt par-
ticles that may cause carburetor flooding.
Transmission Hold and strainer
The transmission bottom pan should be drained every 24,000
miles or 2 years, whichever occurs first, and new fluid added.
For cars in commercial use, and those subjected to heavy city
traffic during hot weather or when the engine is idled for long
periods, the bottom pan should be drained every 12,000 miles.
The strainer should be replaced only after the first 24,000
miles or 2 years, whichever occurs first.
