Rear bumper
Removal
8Remove the rear trim panel from the
luggage compartment by prising up the top
edge to release the clips, then lift the panel
upwards to free it from the lower locating
tags. The bumper retaining nuts are now
exposed (see illustrations).
9Note that the bumper is removed as a
complete assembly with its lower trim panel.
10Disconnect the battery negative lead, then
prise the number plate lamp from the bumper,
and disconnect the wiring.
11Unscrew the bumper retaining nuts, and
recover the washers. On DOHC models, the
bumper securing nuts are accessible from
underneath the vehicle.
12Where fitted, remove the special locking
rivets, one each side, securing the bumper to
the wheel arch.
13Additional clips may be present on the
underside of the bumper which must also be
removed.
14Release the bumper retaining clips at the
front edges of the bumper by tapping the
centre pin through the expanding clip, using a
pin punch or similar. The pin will drop out as it
is pushed through - recover it for refitting.

rear of the vehicle, then pull the end of the
bumper from the rear wing.16Carefully withdraw the bumper from the
vehicle, taking care not to strain the number

pull the upper edge of the grille panel
forwards and free the retaining clips using a
screwdriver. Then lift the panel to release the
lower locating lugs from their grommets in the
lower body front panel (see illustration).

negative lead, then disconnect the
underbonnet lamp wiring plug and feed it
through the cowl panel, noting its routing as a
guide to refitting.
4Working from one end of the cowl panel,
carefully prise the panel from the body. Care
must be taken, as the panel is easily
damaged.

a combination of self-tapping screws and
plastic clips. Removal and refitting is self
explanatory, remembering the following
points (see illustration).
2Some of the securing clips may be held in
place using a central pin, which must be
tapped out to release the clip.
3The clips are easily broken during removal,
and it is advisable to obtain a few spare clips
for possible use when refitting.

13Remove the glass panel, as described
previously in this Section.
14Extract the two securing screws (Allen or
Torx type), then lift the gutter from the roof
aperture.
Refitting
15Refit the gutter to the roof aperture at an
angle, pushing it up to the stop on both sides
until the retaining lugs engage with the gutter
guides.
16Refit and tighten the securing screws,
then refit and adjust the glass panel as
described earlier in this Section.
Sunshade
Removal
17Remove the glass panel and the gutter, as
described previously in this Section. 18Carefully prise the four sunshade spring
clips out of the roof guides using a plastic or
wooden implement to avoid damage, then

remembering the following points.
25Before finally refitting the crank handle,
the crank drive must be adjusted as follows.
26Temporarily refit the crank handle, and
position it so that it faces forwards, then
depress the locking button.
27Remove the crank handle and turn the
crank drive pinion anti-clockwise by hand as
far as the stop.

1The various interior trim panels are secured
by a variety of screws and plastic clips.
2Where press-fit plastic fasteners are used,
it is advisable to use a forked tool similar to
that shown to remove them, to avoid damage
to the clips and the trim panel (see
illustration).
3Removal and refitting of most of the trim
panels is self-explanatory but in all cases,
care must be taken, as the panels are easily
damaged by careless handling and the use of
sharp instruments to release clips.

seat belt lower mountings. Prise up the carpet
to expose the mounting bolts, and unscrew
the relevant bolt(s) from the floor (see
illustrations).
9Prise off the trim, and unbolt the seat belt
upper mounting from the body pillar. Recover
the spacer (see illustration).
10Open the relevant rear door, and pull back
the weatherstrip from the rear of the door
aperture.
11On Hatchback models, remove the
screws securing the upper rear quarter trim
panel to the body. Note that all the screws are
of the Torx type, and when working on the
right-hand side, it will be necessary to open
the first-aid kit/warning triangle cover flap in
the luggage compartment for access to some
of the screws. Withdraw the trim panel
carefully, taking care not to damage
surrounding panels.
12Detach the front edge of the lower rear
quarter trim panel from the body. The panel is
secured by clips on Saloon models, and by
screws on Hatchback models.
13Pull the lower rear quarter trim panel away
from the body sufficiently to gain access to
the seat belt inertia reel unit (see illustration).14Unscrew the securing bolt, and lift the
inertia reel unit from the body panel, then
withdraw the seat belt assembly from the
vehicle.
15If desired, the upper seat belt mounting
height adjuster can be unbolted from the body
pillar (Torx bolts), after removing the upper
rear quarter trim panel (see illustration).
Refitting
16Refitting is a reversal of removal, but note
that, when refitting the height adjuster (where
applicable), the arrows should be uppermost,
pointing towards the vehicle roof. Ensure that
the belt is fitted untwisted.
42Seat belt tensioners - general
5
1All 1993-onwards Cavalier models are
equipped with mechanical front seat belt
tensioners which automatically tighten the
front seat belts in the event of a head-on
collision. The mechanically operated device
ensures that the seat belt remains close to the
body, thus preventing the wearer from sliding
out, under the belt, during impact (see
illustration).
2The tensioner system consists of a powerful
preloaded spring, contained in a cylinder,
which is released in the event of severe
impact. The spring pulls back the seat belt by
means of a bowden cable and fulcrum
mechanism attached to the belt stalk,
mounted on the seat frame.
