Battery flnid level
Battery fluid level should be checked at every engine oil
change. However, in warm weather, fluid level should be
checked at two-week intervals. Maintain battery fluid level
up to the bottom of the slots in each cell.
A fluid level indicator is provided on top of the second cell
cap from the positive battery post. When fluid level is normal,
a black spot appears on the "eye" in the top of this cap. An
off-white spot indicates that fluid level is low. In such case,
check all cells and add water, as necessary, to bring them to
their proper level.
Ordinary tap water may be used except in areas where the
water is known to be exceptionally hard or to have a high
mineral or alkali content. In these areas use distilled water to
fill the battery. If water is added during freezing weather,
drive the car five or six miles before shutting it off. This mixes
the added water with the electrolyte and will prevent it from
freezing and damaging the battery.
Have the battery charge checked regularly during extremely
cold weather. Make sure the cables are clean and tightly
clamped to the battery terminals.
CAUTION: Since the normal battery chemical action
generates hydrogen gas which is highly explosive when
mixed with air, never expose the battery to an open flame
or electric spark. Also, avoid getting battery fluid, which
is sulfuric acid solution, on skin, clothing or other fabrics,
or on painted surfaces. Eye protection should be worn
while working on the battery for any reason.
Windshield washer solution
The recommended mixture of GM Windshield Washer Anti-
freeze and Gas Line De-icer or Optikleen Windshield Washer
Solvent (or the equivalent) should be added to your windshield
washer container during cold weather to retard freezing.
CAUTION: Follow the directions on the label for correct
mixture, otherwise paint damage may result.
Suspension
The suspension and steering linkage connections do not
require periodic lubrication. Suspension connections are packed
with a special long-life lubricant and normally need repacking
only when damaged seals are replaced. Steering linkage pivots
must be replaced when worn or loose.
Carburetor air cleaner and filter
The carburetor air cleaner should be inspected for dust leaks
every spring and fall. Inspect more frequently if the car is
operated in dusty areas. Install a new filter element if needed
