The battery hold down hardware (Fig. 3) includes two bolts, two U-nuts and a hold down strap/battery thermoguard unit. The molded plastic battery hold down strap is integral to the battery thermoguard unit, which encloses the sides of the battery case.

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 Battery Hold Downs in the index of this service manual for the location of the proper battery hold down installation procedures, including the proper hold down fastener tightness specifications.

OPERATION

The battery hold down hardware secures the battery to the battery tray in the engine compartment.

This hardware is designed to prevent battery movement during vehicle operation. Unrestrained battery movement during vehicle operation can result in damage to the vehicle, the battery or both. The battery thermoguard protects the battery from engine compartment temperature extremes. The air trapped between the thermoguard and the battery case creates a dead air space, which helps to insulate the sides of the battery case from the surrounding engine compartment air temperature.

The two hold down U-nuts are installed onto the battery tray before the tray is installed in the engine compartment. The U-nuts are installed over a hole in a molded formation integral to each side of the battery tray. After the battery is properly positioned in the battery tray, the hold down strap/battery thermoguard unit is installed over the top of the battery case. A long hold down bolt is then installed through a hole on each end of the battery hold down strap and threaded into the U-nuts on the battery tray.

The hold down bolts are then tightened to securely hold down the battery in the battery tray.
