2017 Alfa Romeo 4C radiator cap

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 try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads 240°F
(116°C) or greater pull over and stop the vehicle.
Idle the vehicle with the air conditioner turned off
until the coolant temperature drops back into the
normal range 200–230°F (93–110°C). The digital
warning light may switch on (together with a mes-
sage on the instrument cluster display) to indicate
that the coolant temperature is too high; in this case,
stop the engine and call for service.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.

WHAT TO DO IN EMERGENCIES 193

the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifi-
cations, should be obtained immediately.
To minimize the possibility of catalytic converter dam-
age:
•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 malfunctioning operating conditions.
Cooling System
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
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
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
• 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 try to open a cooling
system pressure cap when the radiator is hot.

MAINTAINING YOUR VEHICLE 225

NOTE:
•It is the owner’s responsibility to maintain the proper
level of protection against freezing according to the
temperatures occurring in the area where the vehicle
is operated.
• 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
your local authorized dealer.
• Mixing engine coolant (antifreeze) types is not rec-
ommended and can result in cooling system damage.
If HOAT and OAT coolant are mixed in an emer-
gency, have a authorized dealer drain, flush, and
refill with OAT coolant (conforming to MS.90032) as
soon as possible.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant (antifreeze) and to ensure that engine
coolant (antifreeze) will return to the radiator from the
coolant recovery tank. The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing sur-
faces.
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.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze)
is a regulated substance requiring proper disposal.
Check with your local authorities to determine the
disposal rules for your community. To prevent ingestion
by animals or children, do not store ethylene glycol-
based engine coolant in open containers or allow it to
