BATTERY HOLDDOWN (Continued)
The battery hold down hardware (Fig. 12) includes
two J-bolts, a hold down bracket and two hex nuts
with coned washers. The battery hold down bracket
consists of a stamped steel bracket that is then plas-
tic-coated for corrosion protection.
The hold down J-bolts are installed a hole in the
front and rear flanges of the battery tray from the
top, with the threaded ends of the bolts extending
upward. The hooked end of each J-bolt is then
engaged in a second hole in the front and rear
flanges of the battery tray from the bottom. The bat-
tery hold down bracket is installed across the top of
the battery case and over the two upright threaded
ends of the J-bolts. A hex nut with coned washer is
then installed and tightened onto each of the J-bolts
to securely hold down the battery in the battery tray.
When installing a battery into the battery tray, be
certain that the hold down hardware is properly
installed and that the fasteners are tightened to the
proper specifications. Improper hold down fastener
tightness, whether too loose or too tight, can result in
damage to the battery, the vehicle or both. (Refer to 8
- ELECTRICAL/BATTERY
HOLDDOWN - INSTALLATION) the proper hold
down fastener tightness specifications.

OPERATION

The battery holddown secures the battery in the
battery tray. This holddown is designed to prevent
battery movement during the most extreme vehicle
operation conditions. Periodic removal and lubrica-
tion of the battery holddown hardware is recom-
mended to prevent hardware seizure at a later date.
CAUTION: Never operate a vehicle without a battery
holddown device properly installed. Damage to the
vehicle, components and battery could result.

REMOVAL

All of the battery hold down hardware can be ser-
viced without removal of the battery or the battery
tray.
(1) Turn the ignition switch to the Off position. Be
certain that all electrical accessories are turned off.
(2) Loosen the battery negative cable terminal
clamp pinch-bolt hex nut.
(3) Disconnect the battery negative cable terminal
clamp from the battery negative terminal post. If

threaded ends of the two J-bolts and across the top of
the battery case.
(4) Install and tighten the nut with washer onto
the threaded end of each of the two J-bolts. Tighten
the nuts to 4.7 N·m (42 in. lbs.).
(5) Reconnect the battery negative cable terminal
clamp to the battery negative terminal post. Tighten
