BATTERY SYSTEM (Continued)

The battery tray and support unit also includes a
engine vacuum reservoir, located in the rear of the
unit (Fig. 17). And a drainage hose, located in the
front of the unit (Fig. 17).
OPERATION
The battery tray provides a secure mounting loca-
tion and supports the battery. The battery tray also
provides the anchor point for the battery holddown
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. Unre-
strained battery movement during vehicle operation
could result in damage to the vehicle, the battery, or
both.
The battery tray used on this model also includes a
engine vacuum reservoir and drainage hose. The vac-
uum reservoir provides a storage container for engine
vacuum. Refer to the engine section of the service
manual for more engine vacuum information. The
drainage hose provides means for any liquid that
might collect in the bottom of the battery tray to
drain under the vehicle.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Remove the battery from the vehicle. Refer to
the procedure in this section.
(3) Remove the battery tray retaining fasteners
(Fig. 18).
(4) Pull battery tray up far enough to disconnect
the engine vacuum harness hose from the battery
tray mounted, vacuum reservoir.
(5) Remove the battery tray from the vehicle.
INSTALLATION
(1) Position the battery tray in the vehicle.
(2) Connect the engine vacuum harness hose on
the battery tray mounted vacuum reservoir.
(3) Position drainage hose and install the battery
tray retaining fasteners (Fig. 18).
(4) Install the battery in the vehicle. Refer to the
procedure in this section.
(5) Connect the negative battery cable.
THERMOWRAP
DESCRIPTION
A one-piece slip-on thermowrap unit shields the
battery case from engine compartment heat. The
thermowrap slips over the battery case and due to its
one piece design, the battery cables must be removed
in order to install or remove the thermowrap.
OPERATION
The thermowrap protects the battery from engine
compartment temperature extremes. The tempera-
ture of the battery can affect battery life. The air
trapped in the padded material of the thermowrap
creates a dead air space, which helps to insulate the
sides of the battery case from the air temperature
found in the surrounding engine compartment.
REMOVAL
(1) Disconnect and isolate the negative battery
cable.
(2) Disconnect the positive battery cable.
(3) Lift the battery thermowrap straight up to
remove from the battery.
INSTALLATION
(1) Position the thermowrap on the battery.
(2) Connect the negative and positive battery
cables.

WATER DRAINAGE AND WIND NOISE DIAGNOSIS
The sliding glass panel is designed to seal water
entry with a snug fit between the roof and the seal.
The fit can be checked by inserting a piece of paper
between the roof and the seal. The piece of paper
should have some resistance when pulled out when
the glass panel is in the closed position. The sunroof
housing will drain off a minimum amount of water.
Excessive wind noise could result if the gap clear-
ances are exceeded. The sunroof glass panel may
need to be adjusted. Refer to Sunroof Glass Panel
Adjustment for proper procedures.
Adequate drainage is provided by a drain trough in
the sunroof housing which encircles the sliding glass
panel and leads to drain hoses. If a wet headliner or
other water leak complaints are encountered, before
performing any adjustments, first ensure that the
drainage system is not plugged or disconnected. Use
a pint container to pour water into the sunroof hous-
ing drain trough. If water flow is restricted, use com-
pressed air to blow out any material plugging the
drain system. Retest system again.
To further check for a disconnected drain hose:
(1) Remove A-pillar trim, sun visors, and map
lamps/mini console.
(2) Remove sunroof opening trim lace. Refer to
Sunroof Opening Trim Lace.
NOTE: Care must be taken not to fold or kink the
headliner upon removal.
(3) Lower headliner as necessary to gain access to
sunroof housing drain tubes. Refer to Headlining
Removal and Installation for proper procedures.
(4) Repair as necessary.
DRAIN TUBE
REMOVAL
FRONT HOSES
NOTE: Front A-pillars are filled with sound deaden-
ing foam and the front drain tubes are sealed into
the pillars.
(1) Move glass panel to the fully closed position.
(2) Disconnect negative battery cable.
(3) Remove headliner (Refer to 23 - BODY/INTE-
RIOR/HEADLINER - REMOVAL).
(4) Disconnect the drain hose from the sunroof
housing (Fig. 1).
(5) Drain any liquid from hose connection, repair
as necessary.
REAR HOUSING HOSE
(1) Move glass panel to the fully closed position.
(2) Disconnect negative battery cable.
(3) Remove headliner (Refer to 23 - BODY/INTE-
RIOR/HEADLINER - REMOVAL).
(4) Remove third seat or seats from vehicle.
(5) Remove second seat belt lower anchor.
(6) Remove third seat lower anchor.
(7) Remove quarter trim bolster.
(8) Remove trim panel screws.
(9) Remove quarter trim panel
(10) Disconnect the drain hose from the sunroof
housing. (Fig. 1).
(11) Drain any liquid from hose connection, if nec-
essary, and remove tube.
