2006 Alfa Romeo 156 cooling

CORRECT USE OF THE CAR
203
Keep your speed
down when snow
chains are fitted.
Do not exceed 50 km/h. Avoid
potholes, steps and pavements and
avoid also to drive for long dis-
tances on roads not covered with
snow to prevent damaging the car
and the roadbed.
VEHICLE INACTIVITYIf the car is to be left inactive for long pe-
riods, the following precautions should be
noted:
– House the vehicle under cover in a dry
and possibly ventilated place.
– Engage a gear.
– Check that the handbrake is not en-
gaged.
– Clean and protect the painted parts us-
ing protective wax.
– Disconnect the negative terminal (–)
and check the battery charge. This check is
to be repeated every three months.
Recharge if the optical indicator shows a
dark colour without the central green area.
WARNINGWhere applicable, switch off
the electronic car alarm with the remote con-
trol.– Clean and protect the shiny metal parts
using special compounds readily available.
– Sprinkle talcum powder on the rubber
windscreen and rear window wiper blades
and lift them off the glass.
– Slightly open the windows.
– Cover the car with a cloth or perforated
plastic sheet. Do not use sheets of non-per-
forated plastic as they do not allow mois-
ture on the car body to evaporate.
– Inflate the tyres to 0.5 bar above the
normal specified pressure and check it at in-
tervals.
– If you don’t disconnect the battery from
the electric system, check its charge every
month and recharge it if the optical indica-
tor shows a dark colour without the central
green area.
– Do not drain the engine cooling system. Snow chains cannot be
fitted to the spare wheel
so, if a front (drive) tyre is
punctured and chains must be fit-
ted, the rear wheel should be fit-
ted to the front of the vehicle (in-
flate the tyres to the specified
pressure as soon as possible) and
the spare tyre should be fitted to
the rear. A snow chain can then be
safely fitted to the front wheel.

ENGINE COOLANT LEVEL
Top up only with the same
fluid contained in the cool-
ing circuit. PARAFLU UP
(red) cannot be mixed with
PARAFLU 11 (blue) or with other
fluids. Should this take place, do
not start the engine and contact Al-
fa Romeo Authorized Service.
The level of the coolant in the header tank
(reservoir) should be checked with the en-
gine cold and the car on a level surface and
it should be between the MINand MAX
marks on the tank. If the level is low, loosen
the header tank cap (A) and slowly pour
a mixture of the fluid specified in the ”Flu-
ids and lubricants ” table in section “Tech-
nical Specifications”, through the filler neck
until nearing the MAXmark; have this op-
eration carried out at Alfa Romeo Authorised
Services.
The antifreeze mixture contained in the
cooling circuit guarantees protection down
to –35°C.fig. 16 - 2.5 V6 24V version

Fig. 16: 2.5 V6 24V versionThe cooling system is
pressurised. If necessary,
replace the cap only with
another genuine one, otherwise
system efficiency could be compro-
mised.
Do not remove he cap
when the engine is hot:
danger of burns.
