CLEANING AND INSPECTION

BATTERY

The following information details the recommended

cleaning and inspection procedures for the battery
and related components. In addition to the mainte-
nance schedules found in this service manual and the
owner’s manual, it is recommended that these proce-
dures be performed any time the battery or related
components must be removed for vehicle service.

CLEANING

(1) Clean the battery cable terminal clamps of all

corrosion. Remove any corrosion using a wire brush
or a post and terminal cleaning tool, and a sodium
bicarbonate (baking soda) and warm water cleaning
solution (Fig. 22).

(2) Clean the battery tray and battery hold down

hardware of all corrosion. Remove any corrosion
using a wire brush and a sodium bicarbonate (baking
soda) and warm water cleaning solution. Paint any
exposed bare metal.

(3) If the removed battery is to be reinstalled,

clean the outside of the battery case and the top
cover with a sodium bicarbonate (baking soda) and
warm water cleaning solution using a stiff bristle
parts cleaning brush to remove any acid film (Fig.
23). Rinse the battery with clean water. Ensure that
the cleaning solution does not enter the battery cells
through the vent holes. If the battery is being
replaced, refer to Battery in the index of this service
manual for the location of the factory-installed bat-
tery specifications. Confirm that the replacement bat-
tery is the correct size and has the correct ratings for
the vehicle.

(4) Clean the battery thermoguard with a sodium

bicarbonate (baking soda) and warm water cleaning
solution using a stiff bristle parts cleaning brush to
remove any acid film.

(5) Clean any corrosion from the battery terminal

posts with a wire brush or a post and terminal

cleaner, and a sodium bicarbonate (baking soda) and
warm water cleaning solution (Fig. 24).

INSPECTION

(1) Inspect the battery cable terminal clamps for

damage. Replace any battery cable that has a dam-
aged or deformed terminal clamp.

(2) Inspect the battery tray and battery hold down

hardware for damage. Replace any damaged parts.

(3) Remove the thermoguard from the battery

case. Inspect the battery case for cracks or other
damage that could result in electrolyte leaks. Also,
check the battery terminal posts for looseness. Bat-
teries with damaged cases or loose terminal posts
must be replaced.

(4) Inspect the battery thermoguard for cracks,

deformation or other damage. Replace any battery
thermoguard that has been damaged.

(5) Inspect the battery built-in test indicator sight

glass for an indication of the battery condition. If the
battery is discharged, charge as required. Refer to
Battery in the index of this service manual for the
location of the proper battery diagnosis and testing
procedures for more information on the use of the
battery built-in test indicator. Also refer to Battery
Charging in the index of this service manual for the
location of the proper battery charging procedures.
