BATTERY REPLACEMENT
Removal
(1) Loosen cable clamps.
(2) Use puller to remove cables if necessary. Re
move positive cable first.
WARNING: Use extreme care to prevent dropping bat
tery and splattering the electrolyte because it can cause
severe eye injury and skin burns. Rubber gloves, rubber
aprons, protective eye shields and steel-toed shoes will
decrease the hazards of this type accident. Immediate
first aid is required for electrolyte splashed into the eyes
and on the skin. Electrolyte spills should be immediately
neutralized with a solution of sodium bicarbonate (bak
ing soda) and water and then thoroughly rinsed with
water.
(3) Loosen holddowns and remove battery.
(4) Inspect cables for corrosion and damage. Re
move corrosion using wire brush or post and terminal
cleaner and soda solution. Replace cables that have dam
aged or deformed terminals.
(5) Inspect battery tray and holddowns for corro
sion. Remove corrosion using wire brush and soda solu
tion. Paint exposed bare metal. Replace damaged
components.
(6) Clean outside of battery case if original battery
is to be installed. Clean top cover with a diluted am
monia soda solution to remove acid film. Flush with
clean water. Ensure soda solution does not enter cells.
Remove corrosion from terminals with wire brush or
post and terminal cleaner. Inspect case for cracks or
other damage that would result in leakage of electrolyte.
Installation
(1) Refer to Specifications to determine if battery
has correct rating for vehicle.
(2) Use hydrometer to test battery electrolyte.
Charge if necessary.
CAUTION: Ensure battery tray is clear of loose hard
ware or debris that could damage battery case.
(3) Position battery in tray. Ensure positive and
negative terminals are correctly located. Cables must
reach their respective terminals without stretching.
(4) Ensure tang at battery base is positioned in tray
properly before tightening holddown.
CAUTION: It is imperative that the cables are con
nected to the battery positive-to-positive and negative-
to-negative. Reverse polarity will damage alternator
diodes and radios.
(5) Connect and tighten positive cable first. Then
connect and tighten negative cable.
NOTE: The tapered positive terminal is 1/16 inch (1.6
mm) larger in diameter than the negative terminal. The
opening in the positive cable clamp is correspondingly
larger.
(6) Apply thin coating of petroleum jelly or chassis
grease to cable terminals and battery posts.
(7) Inspect negative cable connections on engine
and vehicle body for condition, security and electrical
continuity.
MAINTENANCE
Always observe the correct polarity when connecting
a charger to a battery. Reversed battery connections will
damage the alternator diodes and radios. The NEGA
TIVE battery terminal is grounded to the engine and
body.
WARNING: Explosive gases are present within and
around the battery at all times. Avoid openflames and
sparks. The danger of battery explosion is compounded
by the fact that the acid would be splattered in every
direction. Wear protective eye shields and clothing when
servicing any battery. Ensure battery has adequate ven
tilation when charging.
It is important that the battery be fully charged when
a new vehicle is delivered. Maintaining a battery at
partial charge could shorten its life.
Inspect electrolyte level in the battery at 15,000 mile
(24 000. km) intervals and at the beginning of the winter
season. Add distilled water to each cell until the level
reaches the bottom of the vent well. DO NOT OVER
FILL. Operate the engine immediately after adding wa
ter (particularly in cold weather) to assure proper
mixing of the water and electrolyte.
Inspect to determine the external condition of the
battery and the cables periodically.
The holddown should be tight enough to prevent the
battery from vibrating or shifting position and cause
damage to the battery case.
