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.

Battery tray

DESCRIPTION

The battery is mounted in a molded plastic tray (Fig. 4) located in the left front corner of the engine compartment. The battery tray is secured on the inboard side with screws to a stamped steel battery tray support located on the left side of the radiator, on the outboard side with screws to the front extension of the left front wheelhouse inner panel and at the front to the front closure panel on the left side of the radiator yoke. The battery tray support is secured at the front with screws to the left side of the radiator yoke, and at the rear with a screw to the front extension of the left front wheelhouse inner panel.

A hole in the bottom of the battery tray is fitted with a battery temperature sensor. Refer to Battery Temperature Sensor in the index of this service manual for the location of more information on the battery temperature sensor. The battery tray also includes two stanchions that are molded into the rear of the tray, which support the forward end of the Power Distribution Center (PDC). Refer to Power Distribution Center in the index of this service manual for the location of more information on the PDC mounting.

OPERATION

The battery tray provides a mounting location and support for the vehicle battery. The battery tray also provides anchor points for the battery hold down hardware. The battery tray and the battery hold down hardware combine to secure and stabilize the battery in the engine compartment, which prevents battery movement during vehicle operation. Unrestrained battery movement during vehicle operation can result in damage to the vehicle, the battery or both.
