2023 ALFA ROMEO GIULIA coolant temperature

189

NOTE:
Always reinstall the oil cap and tighten to proper
torque whenever it is removed to add oil to
engine. Never run the engine with cap removed
as this could cause oil to leak from engine.
Manual Oil Level Checking Procedure —
2.9L Engine
Check that the oil level is between the MIN and
MAX marks on dipstick, clean it with a lint-free
cloth and reinsert it. Extract the dipstick again
and check that the level is between the MIN and
MAX marks.
Top-Up And Oil Level Indication Update On
Display — 2.9L Engine
If an engine oil top-off is needed, in order to
ensure the correct indication of the oil level on
the display, proceed with the following process:
Leave the car on flat ground with the engine
running for approximately five minutes
(temperature higher than 198°F (90°C) and
shut the engine off.
Wait for five minutes, turn the ignition to the
ON mode without starting the engine and wait
for a few seconds.

NOTE:
If the level indication is not updated after the
previously described procedure, repeat the
engine adjustment, shut the engine off and wait
another five minutes before starting it again. If
the indication is not updated after the second
start, contact an authorized dealer.
Top-Up And Oil Level Indication Update On
Display — 2.0L Engine
If an engine oil top-off is needed, in order to
ensure the correct indication of the oil level on
the display, proceed with the following process:
Leave the car on flat ground with the engine
running for approximately five minutes
(temperature higher than 176°F (80°C) and
shut the engine off.
Start the engine again and idle it for about two
minutes.

NOTE:
If you have added the specified amount of oil and
the indicator is not reading “Full”, please contact
an authorized dealer.
ENGINE COOLANT
If the level is too low, remove the cap of reservoir
and add the fluid described on
Ú
page 233.
WASHER FLUID FOR WINDSHIELD/
H
EADLIGHTS
The windshield and headlights washer fluid
reservoir has a telescopic filler.
If the level is too low, remove reservoir cap and lift
the filler. Then, add the fluid described on

Ú
page 233.

NOTE:
Use care when filling under hood fluids such as
engine oil, windshield washer fluid, antifreeze
etc. to minimize spillage onto the top of the
engine. Any excess fluid that is spilled onto the
top of the engine should be removed using
compressed air or an absorbent cloth.
CAUTION!
Make sure not to add too much oil when
topping off the engine. Engine oil in excess
may damage the engine. Have the vehicle
checked. Never exceed the MAX level when
topping off engine oil. It is advisable to check
the oil level in intermediate steps using the oil
dipstick (2.9L Engine Only).
CAUTION!
The oil level is not refreshed immediately on
the display after topping off. Consequently,
wait for the oil level to be refreshed on the
display and see the following procedures.
WARNING!
If the engine oil is being topped up, wait for the
engine to cool down before loosening the filler
cap, particularly for vehicles with aluminum
cap (if equipped). WARNING: risk of burns!
CAUTION!
The oil level must never exceed the MAX mark.
If the MAX mark is exceeded (last notch on the
right turns red) after the fill-up, go to an
authorized dealer as soon as possible to have
the oil in excess removed.
Do not add oil with specifications different
from those of the oil already in the engine.
Used engine oil and oil filters contain
substances which are harmful to the
environment. To change the oil and filters, we
advise you to contact an authorized dealer.

ENGINE COOLING SYSTEM
Coolant Check
Your vehicle has two cooling systems and they
both need to be checked to ensure they are at
proper fill levels.
Check the engine coolant and intercooler coolant
level every oil change or before long trips.
If there are impurities in the engine coolant, the
system must be drained, flushed and refilled:
contact an authorized dealer.
Check the front part of the condenser for any
buildup of insects, leaves or other debris. Should
it be dirty, clean it by spraying delicately with
water.Check the hoses of the engine/intercooler
cooling system to ensure that the rubber has not
deteriorated and that there are no cracks, tears,
cuts or obstructions in the expansion tank side
and radiator side connectors. Should there be
any doubt regarding leaks from the system (e.g. if
frequent top ups are required), have the seal
checked at an authorized dealer.
With the engine off and at normal operating
temperature, check that the cooling system
radiator cap is closed properly.

NOTE:
Before removing the coolant reservoir cap, wait
for the system to cool down.
Topping Up / Draining / Flushing The Engine/
Intercooler Coolant
If the engine coolant (antifreeze) is dirty, have
cleaning and flushing carried out at an authorized
dealer.
For the correct servicing intervals

Ú
page 182.

NOTE:

For topping up, use a fluid with the same
characteristics as those indicated on

Ú
page 233.
Do not use pure water, alcohol-based coolants,
corrosions inhibitors or additional anti-rust
products because they may be incompatible
with the engine coolant and cause the clogging
of the radiator. The use of propylene
glycol-based coolant is also not recommended.
Use care when filling under hood fluids such as
engine oil, windshield washer fluid, antifreeze
etc. to minimize spillage onto the top of the
engine. Any excess fluid that is spilled onto the
top of the engine should be removed using
compressed air or an absorbent cloth.
Engine Cooling/Intercooler System Cap
To prevent loss of engine coolant, make sure that
the expansion tank cap is closed. If it is open,
screw it completely until you reach/hear the click.
Periodically check the cap and clean it from any
foreign bodies that may have deposited on the
external surface.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open the
hood until the radiator has had time to cool.
Never open a cooling system pressure cap
when the radiator or coolant bottle is hot.
Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood
is raised. The fan starts automatically and
may start at any time, whether the engine is
running or not.
When working near the radiator cooling fan,
disconnect the fan motor lead or turn the
ignition to the OFF position. The fan is
temperature controlled and can start at any
time the ignition is in the ON position.
WARNING!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated
engine. Heat causes pressure to build up in
the cooling system. To prevent scalding or
injury, do not remove the pressure cap while
the system is hot or under pressure.
Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
WARNING!
Never add coolant with the engine hot or
overheated.
Do not attempt to cool an overheated engine
by loosening or removing the cap. The heat
causes a considerable increase in pressure
in the cooling system.
To prevent damage to the engine, only use
the engine cooling circuit caps provided.
