water pump Alfa Romeo 166 2006 Owner handbook (in English)

Faulty ABS anti
wheel-locking
This warning light comes on when the
system is inefficient. In this case normal
braking is ensured without though, mak-
ing use of the ABS system. Alfa Romeo
Authorized Services should however be
contacted as soon as possible.
When the ignition key is turned to
MARthe warning light comes on but
must go out after approx. 4 seconds.>
Presence of water
in the fuel oil filter
(JTD 20V Multijet versions)
When the ignition key is turned to the
MARposition the warning light should
come on and must go out after approx. 4
seconds.
The warning light switches on fixed
when driving, to indicate the presence of
water in the fuel oil filter.
In case the indicator light switches on,
even if just for a few seconds, we recom-
mend to contact an Alfa Romeo Autho-
rised Service as soon as possible in order
to purge the water from the fuel oil filter
and avoid severe damages to the injec-
tion pump and to the fuel oil supply cir-
cuit as well as the engine irregular opera-
tion.
c
Glowplugs
(JTD 20V Multijet versions)
The warning light comes on
when the ignition key is turned to MAR
position. When the glowplugs have
reached the established temperature the
warning light will go out. Start the en-
gine as soon as the warning light has
gone out.
For versions/markets where applica-
ble, the warning light flashes for approx.
30 seconds after starting the engine
meaning that there is a fault to the glow
plug warning system, in which case,
contact Alfa Romeo Authorized Services.
With a high ambient temperature the
warning light may turn on imperceptibly.
m
The car is fitted with an
electronic braking device
(EDB). If the
>andxwarning
lights turn on at the same time, this
means that there is an EBD system
fault; in this case violent braking
may be accompanied by early rear
wheel locking, with the possibility
of skidding. Drive the car ex-
tremely carefully to the nearest
Authorized Alfa Romeo workshop
to have the system checked.
WARNING

91
ADDITIONAL HEATER
(Optional, for diesel versions, where
applicable)
The additional heater makes it possible
to integrate heating of the engine coolant
fluid, immediately after starting the en-
gine and when travelling, to more quickly
reach and maintain the optimum operat-
ing temperature of the engine and pas-
senger compartment heater.
The device works completely automati-
cally and it is activated only when the en-
gine is running with an outside tempera-
ture of +5°C or less and a coolant fluid
temperature below 60°C.
When the coolant fluid reaches 61°C,
the electronic control unit reduces the
power of the burner and stops the heater
when a temperature of 72°C is reached,
reactivating it automatically when the flu-
id temperature falls below 60°C. Con-
versely, if after reducing the power of the
burner, the fluid temperature begins to
fall, the control unit cuts in to restore full
power.The system comprises:
– a fuel oil burner for heating the water
and a combustion gas exhaust silencer.
– A batching pump connected to the car
reservoir pipes to supply the burner.
– An electronic control unit for control-
ling burner adjustment.
– An outside temperature sensor.IMPORTANT The heater is fitted with
a thermal limiting device which cuts off
combustion in the event of overheating
due to lack/leaks of coolant fluid.
The heater is also protected by the auto-
matic fuel cut-off switch, which shuts off
the fuel in the event of a crash of a cer-
tain size: to see how this works see the
“automatic fuel cut-off switch” para-
graph.

CHECKING AND TOPPING UP
THE WINDSCREEN/HEADLIGHT
WASHER FLUID
(fig. 12-13)
Access to the windscreen/headlight
washer fluid reservoir, remove the cover
(A-fig. 12) after turning the pins (B).
Then remove the cap (C-fig. 13) and
pour the fluid in the tank until the level
can be seen through the filler neck.
Then close the filler with the cap and re-
fit the cover fastening with the two pins.To avoid damaging the
pump motor do not use
the windscreen washers
when the reservoir is empty.

Symbolπon the con-
tainer indicates synthetic
type brake fluid distinguishing it
from the mineral kind. Using min-
eral type fluids damages the spe-
cial rubber braking system gaskets
beyond repair.
WARNING
Brake and clutch fluid is
poisonous and corrosive.
In the event of contact wash the
parts concerned immediately with
neutral soap and water, then rinse
thoroughly. See a doctor at once if
the fluid is swallowed.
WARNING
Some commercial addi-
tives for windscreen
washers are inflammable. The en-
gine compartment contains hot com-
ponents which could set it on fire.
