1988 OPEL CALIBRA headlamp

13Clean any foreign matter from the float
chamber. Renew the float, the float needle
valve and seat if wear is evident, or if the float
is punctured or otherwise damaged. Check
that the needle valve closes completely before
the float reaches the top of its movement. See
Section 15, for details of float level checking.
14Renew the diaphragms in the part-load
enrichment valve and in the accelerator pump.
If additional pump or valve parts are supplied
in the overhaul kit, renew these parts also.
15Further dismantling is not recommended.
Pay particular attention to the throttle opening
mechanism arrangement if it is decided to
dismantle it; the interlocking arrangement is
important.
16Reassemble in the reverse order to
dismantling. Use new gaskets and seals
throughout; lubricate linkages with a smear of
molybdenum based grease.
Refitting
17Carry out the following procedure before
refitting.
a)Position the fast idle adjustment screw on
the highest step of the fast idle cam.
b)Use a gauge rod or twist drill of the
specified diameter to measure the
opening of the primary throttle valve.
c)Adjust if necessary at the fast idle
adjustment screw.
d)Note that this is a preliminary adjustment;
final adjustment of the fast idle speed
should take place with the engine running.
18Refitting is a reversal of removal, but
renew the gasket(s).
19After refitting, carry out the following
checks and adjustments.
20Check the throttle cable free play and
adjust if necessary, as described in Section 11.
21Check and if necessary top-up the
coolant level, as described in Chapter 3.
22Check and if necessary adjust the idle
speed and mixture, as described in Section 14.
14Idle speed and mixture -
adjustment
3
Note: Refer to Section 2 before proceeding.
To carry out the adjustments, an accurate
tachometer and an exhaust gas analyser (CO
meter) will be required
1To check the idle speed and mixture
adjustment, the following conditions must be
met:
a)The engine must be at normal operating
temperature
b)All electrical consumers (cooling fan,
heater blower, headlamps, etc.) must be
switched off
c)The ignition timing and spark plug gaps
must be correctly adjusted - see Chapters
1 and 5
d)The throttle cable free play must be
correctly adjusted - see Section 11
e)The air inlet trunking must be free from
leaks, and the air filter must be cleanf)On automatic models, always select
position, “P”.
2Connect a tachometer and an exhaust gas
analyser to the vehicle, according to the
equipment manufacturer’s instructions.
3Start the engine, and run it at 2000 rpm for
approximately 30 seconds, then allow it to
idle. If the idle speed is outside the specified
limits, adjust by means of the throttle stop
screw (see illustration).
4When the idle speed is correct, check the
CO level in the exhaust gas. If it is outside the
specified limits, adjust by means of the idle
mixture adjustment screw. In production, the
screw is covered by a tamperproof plug;
ensure that no local or national laws are being
broken before removing the plug (see
illustration).
5On automatic models, when position “D” is
selected (all electrical systems switched off),
the idle speed should not drop perceptibly. If
it does, the vehicle should be taken to a
Vauxhall dealer for the idle-up system to be
checked using special Vauxhall test
equipment.
6With the idle mixture correct, readjust the
idle speed if necessary.
7If the cooling fan cuts in during the
adjustment procedure, stop the adjustments,
and continue when the cooling fan stops.
8When both idle speed and mixture are
correctly set, stop the engine and disconnect
the test equipment.
9Fit a new tamperproof plug to the idle
mixture adjustment screw, where this is
required by law.
15Needle valve and float -
removal, inspection and
refitting
4
Note: Refer to Section 2 before proceeding. A
new carburettor top cover gasket must be
used on reassembly. A tachometer and an
exhaust gas analyser will be required to check
the idle speed and mixture on completion
Removal
1Disconnect the battery negative lead.
2Remove the round air cleaner, on
applicable models. On other models,
disconnect the air trunking from the air
cleaner, then disconnect the vacuum pipe and
breather hose from the air box. Extract the
three securing screws and lift off the air box,
complete with air trunking.
3Thoroughly clean all external dirt from the
carburettor.
4Disconnect the fuel supply hose at the
carburettor. Be prepared for fuel spillage, and
take adequate fire precautions. Plug the end
of the hose, to prevent dirt ingress and further
fuel spillage.
5Identify the automatic choke coolant hose
locations as an aid to refitting, then
disconnect the hoses. Be prepared for
coolant spillage, and either plug the hoses, or
secure them with their ends facing upwards,
to prevent further coolant loss.
6Disconnect the choke heater wiring plug.
7Disconnect the lower vacuum hoses from
the choke pull-down unit.
8Remove the four carburettor top cover
securing screws, noting their locations, as two
lengths of screw are used (see illustration).
9Lift off the top cover and recover the
gasket.
Inspection
10Hold the cover vertically, so that the float
is hanging from its pivot. Then tilt the cover
until the float needle valve is just closed - the
needle spring must not be compressed by the
weight of the float.
11Measure the distance, dimension x (see
illustration),from the bottom of the float to
the gasket surface on the top cover’s

27Headlamps -alignment
2
1Correct alignment of the headlamp beams
is most important, not only to ensure good
vision for the driver, but also to protect other
drivers from being dazzled.
2Accurate alignment should be carried out
using optical beam setting equipment.
3In an emergency, adjustments may be
made by turning the adjustment screws
shown (see illustrations). If an adjustment is
made, the alignment should be checked using
beam setting equipment at the earliest
opportunity.
4All 1992-on models are fitted with the
headlamp aim adjustment system, operated
through the facia-mounted switch (see
illustration).
a)Position ‘0’, is for correct alignment if just
the driving seat is occupied.
b)Position ‘1’, if all seats are occupied.
c)Position ‘2’, if all seats occupied and
luggage.
d)Position ‘3’, for just driver and luggage.
28Headlamp dim-dip system -
general, removal and refitting
3
General
1The system (where fitted) is governed by the
dim-dip control unit mounted either behind
and above the glovebox (early models), or
behind the main fuse panel (later models).
2The control unit uses the oil pressure
warning lamp circuit to ensure that, when theengine is running and the sidelamps are
switched on, reduced current is fed to the
headlamp dipped-beam circuits. This lights
the headlamps with approximately one-sixth
of their normal power so that the vehicle
cannot be driven using sidelamps alone.
3To locate the dim-dip control unit, open the
main fuse panel covering flap and unclip it
from its bottom and top mountings (Section 3).
Then use a torch to see whether the unit is
fastened to the plastic bracket behind the facia
and fuse panel. The unit is usually rectangular,
of black plastic, and can be identified by the
colours of the five wires leading to it (see
applicable wiring diagram).
Removal
4If the unit can be seen, remove the driver’s
side lower facia and footwell trim panels
(Chapter 11), then unscrew the four retaining
screws and lower the plastic bracket until the
control unit can be detached.
5If the unit cannot be seen, remove the
glovebox assembly (Chapter 11). The unit will
be fastened to the underside of the facia top
surface.

1The wiper blades should be renewed when
they no longer clean the glass effectively.

some models it may be more convenient to do
this with the bonnet open.

the spring clip and slide the blade from the
hook (see illustration).
4If necessary, extract the two metal inserts
and unhook the wiper rubber.
