2008 Alfa Romeo 166 checking oil

55
IMPORTANTSThe triggering of air
bags releases a small amount of powder.
This powder is not harmful and does not
indicate a start of fire; also the surfaces
of the deployed bag and the car interior
may be covered with dusty residue: this
may irritate the skin and eyes. In the
event of exposure, wash with neutral
soap and water.
The air bag system has a validity of 14
years as concerns the pyrotechnic charge
and 10 years as concerns the coil contact.
Contact Alfa Romeo Authorized Services as
this date approaches.IMPORTANTIf an accident has trig-
gered the air bag, Alfa Romeo Authorized
Services must be contacted to have the de-
vices activated replaced and to have the
whole system checked.
All operations involving checking, repair-
ing and replacing components concerning
the Air bag must be carried out by Alfa
Romeo Authorized Services.
If the car is to be demolished, Alfa Romeo
Authorized Services should be contacted be-
forehand to have the system deactivated.
If the car changes ownership, the new
owner must be informed of the instructions
for use and of the above warnings and be
given this “Owner’s Manual”.
IMPORTANTThe triggering of the pre-
tensioners, front air bags and side bags is
decided by the electronic control unit in a
differentiated manner depending on the
type of crash. The failure to trigger one or
more of them does not necessarily indicate
a system malfunction.GENERAL WARNINGS
Never lean head, arms
and elbows out of the
window.
WARNING
If the ¬warning light
does not turn on when
turning the ignition key to MAR or
if it stays on when travelling, this
could indicate a failure in safety re-
taining systems; under this condi-
tion air bags or pretensioners could
not trigger in the event of collision
or, in a restricted number of cases,
they could trigger accidentally.
Stop the car and contact a Alfa
Romeo Authorized Services to
have the system checked.
WARNING
Do not cover back rest of
front seats with trims or
covers there are not set for the
use of side bags.
WARNING

155 VEHICLE INACTIVITY
If the vehicle is to be left inactive for
long periods the following precautions
should be noted:
– House the vehicle under a cover in a
dry and possibly ventilated place.
– Engage a gear.
– Release the handbrake.
– Clean and protect the paintwork by
applying silicon wax.
– Cover the rubber windscreen wiper
blades with talcum powder and raise
them off the glass.
– Open the windows slightly.
– Cover the vehicle with a cloth or per-
forated plastic cover. Do not use compact
plastic covers which prevent the humidity
on the surface of the vehicle from evapo-
rating.
– Inflate the tyres to a pressure of 0.5
bars above normal. If possible rest the
tyres on wooden planks and periodically
check the pressure.– Switch off the alarm system (if fit-
ted) with the remote control, then deacti-
vate it with the emergency key.
– Disconnect the terminals from the
battery poles (negative pole first) and
check the battery charge. When the vehi-
cle is in storage, this check should be car-
ried out once a month. If the no-load volt-
age is less than 12.5V, recharge the bat-
tery.
REMOVING FROM STORAGE
Before using your vehicle after a long
period of inactivity the following opera-
tions should first be carried out:
– Do not dust the outside of the vehi-
cle.
– Visually check that there are no
leaks (oil, brake and clutch fluid, engine
coolant etc.).
– Replace the engine oil and filter.
– Check:
Gearbox-differential oil level
Brake-clutch fluid level
Level of engine coolant fluid.– Check the air cleaner and replace if
necessary.
– Check tyre pressure and ensure that
they are not damaged, cracked or cut. If
they are they must be replaced.
– Check the state of the drive belts in
the engine bay.
– Connect the cables of the battery af-
ter checking that the charge is adequate.
– Re-activate the alarm system, if fit-
ted, using the emergency key.
– With the gear lever in neutral start
the engine and allow the engine to run
for a few seconds whilst repeatedly
pumping the clutch pedal.

206 ANNUAL INSPECTION
PLAN
An annual inspection plan has
been established for cars that cov-
er less than 20,000 km a year
(e.g. 10,000 km). It consists of
the following:
– Checking the condition/wear of tyres,
and adjusting pressure (including the com-
pact spare wheel, where applicable).
– Checking the lighting system (head-
lights, turn indicators, hazard warning
lights, boot light, passenger compart-
ment, warning lights of instrument panel,
etc.).
– Checking the working order of the
windscreen wiper-washer and adjusting
the nozzles.
– Checking the positioning/wear of the
windscreen wipers.
– Checking the condition and wear of
the front brake pad.– Sight inspect the conditions of: en-
gine, gearbox, transmission, pipes and
hoses (exhaust - fuel - brakes), rubber
parts (boots, sleeves, bushes, etc.).
– Check for bonnet and boot lock clean-
ness, lever cleanness and lubrication.
– Check battery charge and fluid level
(electrolyte).
– Visually checking the condition of the
belts and various controls.
– Checking and topping up, if neces-
sary, the level of liquids (coolant, brake
fluid, windscreen washer fluid, battery
etc.).
– Change engine oil and oil filter, if re-
quired.
– Check and replace pollen filter, if re-
quired.
– Check and replace air cleaner, if re-
quired.
ADDITIONAL OPERATIONS
Every 1000 kmor before long jour-
neys check and if necessary top up:
– the engine coolant fluid level
– brake fluid/hydraulic clutch control
fluid level
– power steering fluid level
– windscreen washer and headlamp
washer fluid level
– tyre pressure and conditions.
– check light system operation (head-
lights, direction indicators, hazard lights,
etc.).
– check windscreen wiper/washer op-
eration and windscreen/rear window
blade position/wear.
Every 3000 kmcheck the level of
the engine oil and top up if necessary.
Every 5000 km(only for fuel oil en-
gines): drain the condensation water
from the filter. You are recommended to
use products of the FL Selenia, de-
signed and developed expressly for Alfa
Romeo cars (see the table “Fluids and lu-
bricants” in the Technical specifications”
chapter).

PROTECTIVE SHIELD UNDER
ENGINE
The car is fitted with a protective shield
under the engine.
IMPORTANTWhen changing the en-
gine oil and filter, checking and changing
the gearbox and differential oil, this pro-
tection should be removed. This operation
should be carried out by Alfa Romeo Au-
thorized Services.
CHECKING ENGINE OIL LEVEL
Fig. 3:3.2 V6 24V version
Fig. 4:JTD 20V Multijet version
The engine oil level should be checked
when the vehicle is standing on a level
surface a few minutes (about 5) after the
engine has been switched off.
Remove the dipstick (A), clean it, then
re-insert it completely, remove it once again
and check that the level is between the
MIN and MAX marks on the dipstick.The interval between the MIN and MAX
marks corresponds to approximately 1
litre of oil.
Max. engine oil consumption is usually
400 grams every 1000 km.
When the car is new, the engine needs
to run in, therefore the engine oil con-
sumption can only be considered sta-
bilised after the first 5000-6000 km.

When the level falls to the MIN mark,
cap (B) should be removed and the sys-
tem topped up to the MAX mark through
the filler neck.
Do not exceed the MAX mark when top-
ping up with engine oil.IMPORTANT After topping up the en-
gine oil, before checking the level, run the
engine a few seconds and wait for a few
minutes (approx. 5) after stopping it.
To avoid burns particular
care should be taken
when working inside the engine
compartment when the engine is
warm.

Fig. 10:3.2 V6 24V version
Check that the oil in the reservoir is at
the maximum level.
This operation must be carried out with
the car on level ground and when the en-
gine is stationary and cold.
fig. 8 - JTD 20V Multijet versionfig. 9 - JTD 20V Multijet versionfig. 10 - 3.2 V6 24V version On JTD 20V Multijet versions access to
the reservoir is gained by removing the cov-
er (A-fig. 8) after turning the fastening
pins withdraw the tube (B-fig. 9).
Slacken the cap (C-fig. 9-10) and
check that the level corresponds to the
reference notch of the maximum level on
the dipstick which is an integral part of
the cap.
TOPPING UP THE POWER
STEERING OIL
If the level of the oil in the power steer-
ing reservoir falls below the specified lev-
el, top up only with one of the products
listed in he table of “Fluids and lubri-
cants” in the “Technical specifications”
chapter as follows.
– Start the engine and allow the oil in
the reservoir to settle.
– When the engine is running turn the
steering wheel lock to lock a few times.
– Top up the MAX level notch and then
replace the cover.

When the cap (B) is
screwed off the reser-
voir ensure that the
electrical connections are not dis-
connected. Make sure that the
highly corrosive brake fluid
does not drip onto the paint-
work. If it does, wash it off
immediately with water.
IMPORTANT Contact Alfa Romeo Au-
thorized Services for maintenance and re-
pair operations.Oil consumption is very
low; if topping up again
is needed shortly after-
wards, have the system checked
for possible leaks by Alfa Romeo
Authorized services.
CHECKING AND TOPPING UP
THE BRAKE AND CLUTCH
FLUID
(fig. 11)
Check that the fluid level in the reservoir
is at maximum. Top up with the brake flu-
id specified in the table “Fluids and lubri-
cants” (see section “Technical Specifica-
tions ").
NOTEClean accurately the tank cap A
and the surrounding surface. When open-
ing the cap take the utmost care to pre-
vent impurities entering the tank. When
topping up, always use a funnel with
built-in filter with mesh equal to or lower
than 0.12 mm. On JTD 20V Multijet versions insert the
tube on the cap and refit the cover fasten-
ing with the three screws.
Do not allow power
steering fluid to touch hot
engine parts: it is inflammable.
