Cooling System - Alfa Romeo 4C Spider 2020 Owner's Manual

120 SERVICING AND MAINTENANCE
CAUTION!
The catalytic converter requires the use of

unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri-
ously reduce engine performance and
cause serious damage to the engine.
Damage to the catalytic converter can result

if your vehicle is not kept in proper operating
condition. In the event of engine malfunc-
tion, particularly involving engine misfire or
other apparent loss of performance, have
your vehicle serviced promptly. Continued
operation of your vehicle with a severe
malfunction could cause the converter to
overheat, resulting in possible damage to
the converter and vehicle.
Under normal operating conditions, the
catalytic converter will not require
maintenance. However, it is important to keep
the engine properly tuned to ensure proper
catalyst operation and prevent possible catalyst
damage.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly
malfunctioning engine operation, a scorching
odor may suggest severe and abnormal catalyst
overheating. If this occurs, stop the vehicle, turn
off the engine and allow it to cool. Service,
including a tune-up to manufacturer's
specifications, should be obtained immediately.
To minimize the possibility of catalytic converter
damage:
Do not shut off the engine or interrupt the

ignition, when the transmission is in gear and
the vehicle is in motion.
Do not try to start the engine by pushing or

towing the vehicle.
Do not idle the engine with any spark plug

wires disconnected or removed, such as
when diagnostic testing, or for prolonged
periods during very rough idle or malfunc-
tioning operating conditions.

OOLING YSTEM
WARNING!
Turn vehicle off and disconnect the fan

motor lead before working near the radiator
cooling fan.
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 pres-
sure cap when the radiator or coolant bottle
is hot.
WARNING! (Continued)
Keep hands, tools, clothing, and jewelry

away from the radiator cooling fan when
the hood is raised. The fan starts automati-
cally 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 switch to the OFF position. The fan is
temperature controlled and can start at any
time the ignition switch is in the ON position.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine coolant
(antifreeze) is dirty or rusty in appearance, the
system should be drained, flushed and refilled
with fresh engine coolant (antifreeze). Check the
front of the A/C condenser for any accumulation
of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically
down the face of the condenser.
Cooling System — Drain, Flush And Refill
NOTE:
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage. If any coolant is needed to be added to
the system please contact an authorized dealer.
