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 electrolyte level in the battery. Use
a putty knife or another suitable wide flat-bladed tool
to pry the cell caps off (Fig. 31). Do not use a screw-
driver. Add distilled water to each cell until the liq-
uid reaches the bottom of the vent well. DO NOT
OVERFILL.
