1Working in the engine compartment,
disconnect the cable from the bonnet lock by
pulling the cable sheath end fitting from its
bracket, then releasing the end fitting from the
lock lever.
2Remove the three securing screws and
withdraw the lock from the front panel.
3Refitting is a reversal of removal.
Models from 1987
4Remove the radiator grille panel.
5Disconnect the cable from the bonnet lock
by pulling the cable sheath end fitting from its
bracket, then releasing the end fitting from the
lock lever.
6Detach the bracing strut from the lock by
removing the screw, then remove the two
securing screws and withdraw the lock from
the front panel.
7Refitting is a reversal of removal.
Removal
1Open the boot lid, and place protective
covers (old rags or cardboard) beneath the
corners of the lid, and over the rear wings to
prevent damage to the paintwork.
2Where applicable, disconnect the wiring
from the lock solenoid and “boot lid ajar”
sensor, after disconnecting the battery
negative lead.
3Release the wiring loom grommets, taking
care not to lose them, then tie string to the
wiring loom(s), and pull the loom(s) through
the boot lid. Leave the string(s) in position in
the boot lid to aid refitting of the loom(s).
4Mark the location of the hinges on the
underside of the lid using a soft pencil or
masking type, then loosen the four hinge bolts.5With the help of an assistant, remove the
bolts and lift the boot lid from the vehicle.
Refitting
6Refitting is a reversal of removal, bearing in
mind the following points.
7Adjust the hinges to their original marked
positions before tightening the bolts.
8On completion, check that the boot lid is
central within its aperture and aligned with the
surrounding bodywork. Re-adjust the hinges
to give satisfactory alignment if necessary.
9Check that the lock striker engages fully in
the lock, and if necessary adjust the position
of the lock striker.
Removal
1With the boot lid raised, remove the lock
barrel retaining clip.
2Where applicable, disconnect the operating
lever from the central locking solenoid/motor,
then withdraw the lock barrel.
3Remove the three retaining screws from the
lock assembly, if necessary loosening the
reinforcing plate (see illustration).
4Where applicable, disconnect the battery
negative lead, the earth lead from the bootlid
and the “boot lid ajar” sensor wiring plug.
Unclip the luggage compartment light switch
from the lock assembly, where applicable.
5Withdraw the lock assembly from the boot
lid.
Refitting
6Commence refitting by inserting the lock
assembly and loosely refitting the retaining
screws.
7Insert the lock barrel, where applicable
reconnecting the operating lever to the
solenoid, and refit the retaining clip.
8Tighten the lock assembly retaining screws,
and where applicable reconnect the earth
lead and “boot lid ajar” sensor wiring plug,
and the battery negative lead.
9If the reinforcing plate was loosened during
removal, tighten the retaining screws.Note: On Hatchback models made before
1990 with an integral heated rear
window/radio aerial, note that the radio aerial
lead is routed through different openings to
that of other models in the rear bodywork and
the tailgate. If a new, later-specification
tailgate is to be fitted to an earlier vehicle, a
new opening must be made in the bodywork
for the aerial lead. Ideally, this work should be
carried out by a Ford dealer, who will have the
necessary template available to ensure that
the opening is positioned accurately.
Removal
1Disconnect the battery negative lead.
2Open the tailgate and prise out the trim
panel using a wide-bladed screwdriver.
3Disconnect the wiring from the heated rear
window, rear wash/wipe, interior light, lock
solenoid and “tailgate ajar” sensor, as
applicable. Disconnect the washer fluid hose
where applicable; be prepared for fluid
spillage.
4Release the wiring loom/hose grommet(s)
taking care not to lose it/them, then tie string
to the wiring loom(s)/hose, and pull the
loom(s)/hose through the tailgate. Leave the
string(s) in position in the tailgate to aid
refitting of the loom(s)/hose.
5Have an assistant support the tailgate, then
disconnect the support struts by prising out
the retaining clips. Do not remove the clips
completely, just raise them by a maximum of
4.0 mm (0.16 in) and then pull the struts off
their mountings (see illustration).
6Prise out the hinge fixing covers from the
headlining, unscrew the hinge nuts and
washers, and with the aid of the assistant,
withdraw the tailgate from the vehicle (see
illustration).
Refitting
7Refitting is a reversal of removal, but do not
fully tighten the hinge nuts until the tailgate is
positioned centrally in its aperture. If
necessary, adjust the position of the lock
striker so that it engages fully in the lock.

an earlier vehicle, the door panels must be
modified as follows to enable refitting of the
original components.
15Remove all the serviceable components
and fasteners from the original door.
16Working on the new door, use a small
round file to elongate the door interior handle
mounting hole “A” (see illustration)vertically
downwards so that it will align with the
