Engine Cooling System - Alfa Romeo Giulia 2024 Owner's Manual

Open welding or loose connections may permit exhaust
gas to enter the passenger compartment.
Have the exhaust system checked every time the
vehicle is raised. Replace the components where
necessary (for these operations, contact an authorized
dealer).
In normal operating conditions, the catalytic converter
does not require maintenance. To ensure that it
operates correctly, however, and prevent it from getting
damaged, it is extremely important that the engine
operates perfectly.
To minimize the risk of damaging the catalytic
converter, proceed as follows:
□
Do not stop the engine or deactivate the ignition
with gear engaged and vehicle in motion.
□
Do not attempt to start the engine by bump starting.
□
Do not persist in using the vehicle if idling is very
irregular or the operating conditions are very notably
irregular.
WARNING!
□
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you unconscious
and can eventually poison you.
□
A hot exhaust system can start a fire if you park
over materials that can burn. Such materials
might be grass or leaves coming into contact with
your exhaust system. Do not park or operate your
vehicle in areas where your exhaust system can
contact anything that can burn.

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.
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.
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.
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.
