In freezing weather the vehicle must be driven after adding
water to properly mix it with the electrolyte and prevent freez-
ing. It is also important to keep the battery in a fully charged
condition in cold weather as a discharged battery will freeze
at a little below the freez-
ing point of water (32 de-
grees F.).
The state of charge in the
battery should
be
checked
regu larly . Your Chevrolet
dealer will gladly perform
this
service; however, if
it is
inconvenient to take the
truck to the dealer the state
of charge
in
the battery can
be checked by using a
bat-
tery hydrometer as shown in

batteries. When corrosion appears on the terminals they should
be cleaned in a solution of baking soda and water or ammonia
