wheel bolts Alfa Romeo 166 2008 Owner handbook (in English)

144
– Two or more spare wheels should never
be used together. Have the wheel changed
repaired and refitted as soon as possible.
Rims
The bolts should be tightened to a
torque of 86 Nm (8.8 kgm).
Tyres
The tyres installed on the vehicle are of
the tubeless type and do not have an in-
ner tube. To obtain the greatest degree of
comfort, safety and length of life of the
tyres, the following recommendations
should be observed.
– With new tyres do not drive at full
speed until the first 100 km have been
reached.
– Before entering a tight bend, even if
the vehicle permits it, reduce speed.
– Avoid sharp acceleration and unneces-
sary braking.
– Do not travel for long periods at sus-
tained high speed especially on rough
roads.– Have the wheels balanced and the
front and rear axles set correctly.
– Avoid hitting the side walls of the
tyres, for example when parking.
– Never tamper with the valve on the
tyre.
– Do not insert anything between the
rim and the tyre.
– If the rim is bent, have it replaced.
– In the event of an abnormal drop in
the tyre pressure replace the wheel and
have it checked.
– When balancing the wheels use the
counterweights which are specifically de-
signed for tubeless tyres. To balance light
alloy rims only Alfa Romeo original
weights should be used.
– The tyre pressure, including that of
the spare wheel must reflect the indica-
tions given in the “Technical specifica-
tions” of this manual.
– Have the tyres checked periodically to
ensure that they are not damaged in any
way.– Second-hand tyres of unknown origin
or over 6 years old must only be used in
emergencies and with great care.
– Inner tubes must not be fitted to
tubeless tyres.
– Avoid parking the vehicle on the edge
of a step or other irregularities in the road
surface.
– Have the tyre tread checked periodi-
cally and replace when the legal mini-
mum is reached.
IMPORTANT Some types of tyres are
fitted with wear indicators. As soon as
these wear indicators appear on the tyre
tread, the tyres must be replaced.
Periodically check that the tyres are not
showing signs of irregular tread wear. If
they are, contact Alfa Romeo Authorized
Services who will eliminate the cause of
irregular wear.
Tread wear increases the danger of
aquaplaning on wet surfaces.

158IN THE EVENT
OF A PUNCTURE
Wheel changing and cor-
rect use of the jack and
spare wheel call for some precau-
tions as mentioned below.
Signal the presence of the station-
ary vehicle according to current
regulations: hazard warning lights,
reflecting triangle, etc.
Any passengers should leave the
car, specially if the vehicle is heav-
ily laden, and wait for the wheel
to be changed out of harm of the
traffic.
If parked on a slope or rough road,
place wedges or other suitable de-
vices under the wheels to prevent
the car from rolling. Do not grease
the threads of bolts before in-
stalling them; they might slip out.
WARNING
The spare wheel is specific
to your model of car: do
not use it on another model or use
the spare wheel of other models on
your car. On cars fitted with tyres
215/55 R16 (*), 225/45 R17,
235/40 R18 and spare wheel with
tyre 215/55 R16 (*), since the
spare wheel is different from the
standard wheels, observe the in-
structions for use given below:
– The spare wheel should only be
used in an emergency.
– Use of the spare wheel should
be kept to a minimum. Do not
drive at speeds of over 80 km/h.
– The car will handle differently
when the spare wheel is fitted.
Avoid sudden acceleration or brak-
ing, sharp corners and fast bends.
– Check at regular intervals that
spare wheel pressure is equal to
2.7 bar (2.7 kg/cm
2).
– Two or more spare wheels
should never be used together.
Have the wheel changed repaired
and refitted as soon as possible.
WARNING
On cars fitted with tyres
215/55 R16 (*), 225/
45 R17, 235/40 R18 and spare
wheel with tyre 215/55 R16 (*),
do not apply the wheel cap on the
spare wheel. The spare wheel has
an orange sticker with the main
cautions about use of the wheel it-
self and instructions for use.
The sticker must absolutely never
be removed or covered.
The sticker contains the following
instructions in four languages:
– WARNING! Only for temporary
use 80 km/h max!
– Replace with standard service
wheel as soon as possible.
– Do not cover these instructions.
The vehicle may fall if the jack is
not positioned correctly.
WARNING
(*) Tyre 205/55 R16 for versions/mar-
kets where applicable.

– Remove the wheel cap (A-fig. 4)
(only for versions with steel rims) lever-
ing on the edge with the flat-tipped
screwdriver provided in the tool bag.– Using the L-wrench (B-fig. 5) pro-
vided, loosen the fastening bolts (A) by
about one turn.
– Position the jack under the car next
to the wheel to be replaced (fig. 6):Position1: changing a rear wheel;
Position2: changing a front wheel.
– Turn the knob (A-fig. 7) of the jack
to extend it until the pin (B), on the on
the upper part of the jack inserts correctly
in the seat on the body (C).
– Fit the L-wrench (A-fig. 8) on the
jack pin (B).
– Work the jack and raise the car, until
the wheel is a few centimetres above
ground.
– Completely unscrew the fastening
bolts (A-fig. 9) and remove the wheel.
– Make sure the spare wheel is clean
and free of impurities on the hub contact
surface which could cause slackening of
the fastening bolts later.
– Install the spare wheel making the
hub pin (A-fig. 10) coincide with one
of the holes (B-fig. 11) of the wheel.

– Tighten the five fastening bolts (A-
fig. 12).– Lower the car and remove the jack
(fig. 13).– Completely tighten the bolts in the se-
quence shown (fig. 14).
– On cars having the same alloy rims
as the spare wheel ones, wheel cap can
be fitted following the instructions given
in the following paragraph.
IMPORTANTNever fit the wheel cap
to the spare wheel if the spare wheel is
different from the standard one.
After refitting a wheel:
– Stow the spare wheel in the space
provided in the luggage compartment and
fasten it with the ring nut (A-fig. 2).
– Put jack and tools back in the bag and
stow it in the boot.

REFITTING A NORMAL WHEEL
Refit the wheel as described below:
– Stop the car in such a position that it
is not dangerous for the traffic where it is
possible to change the wheel safely.
Where possible, park on a level, compact
surface.
– Engage the handbrake
– Engage 1st gear or reverse. For cars
with automatic gearbox set the lever to
positionP.
– Open the boot.
– Fold back the boot mat (A-fig. 1).– Take the tool bag (A-fig. 3) and
the spare wheel and bring them near to
the wheel to be changed.
– Remove the wheel cap (A-fig. 4)
(if present) levering on the edge with the
flat-tipped screwdriver provided in the tool
bag.– Using the L-wrench (B-fig. 5) pro-
vided, loosen the fastening bolts (A) by
about one turn.
– Position the jack under the car next
to the wheel to be replaced (fig. 6):
Position1: changing a rear wheel;
Position2: changing a front wheel.
– Turn the knob (A-fig. 7) of the jack
to extend it until the pin (B), on the on
the upper part of the jack inserts correctly
in the seat on the body (C).
– Fit the L-wrench (A-fig. 8) on the
jack pin (B).

– Work the jack and raise the car, until
the wheel is a few centimetres above
ground.
– Completely unscrew the fastening
bolts (A-fig. 16) and remove the
wheel.
– Make sure that the wheel to be in-
stalled is clean and free of impurities on
the hub contact surface which could cause
slackening of the fastening bolts later.
– Install the wheel making the hub pin
(A-fig. 10) coincide with one of the
holes (B-fig. 11) of the wheel.
– Tighten the five fastening bolts (A-
fig. 17).
For cars with alloy rims it is easier to in-
sert the wheel bolts using the specific
centering pin.– Screw the centering pin (A-fig. 18)
in one of the fastening bolt holes.
– Push the wheel on the pin and fasten
it with four bolts.
– Remove the centering pin (A-fig. 19)
and screw the last fastening bolt.– Lower the car and remove the jack
(fig. 20).
– Completely tighten the bolts in the se-
quence shown (fig. 21).
– If present, fit the hub cap so that the
valve can come out through the tapered
hole. Press the edges of the hub cap s-
tarting from near the valve hole (A-
fig. 22) and proceeding round until it is
securely attached.
IMPORTANT Incorrect fitting might
cause the wheel cap to come off when
the car is on the move.
After refitting a wheel:
– Stow the spare wheel in the space
provided in the luggage compartment and
fasten it with the ring nut (A-fig. 2).

Do not grease the threads
of bolts before installing
them; they might slip out.
The bolts should be tightened to a
torque of 86 Nm (8.8 kgm).
You are advised to have the wheel
bolt tightening checked by Alfa
Romeo Authorized Services as
soon as possible.
Indeed, insufficient tightening may
cause the wheel bolts to slacken
with the obvious dangerous con-
sequences. Excessive tightening
can strain the bolts.
