2017 Alfa Romeo 4C coolant temperature

1. Temperature Gauge•The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range
indicates that the engine cooling system is operat-
ing satisfactorily.
• The digital gauge will likely indicate a higher
temperature when driving in hot weather, or up
mountain grades. It should not be allowed to
exceed the upper limits of the normal operating
range.
NOTE: Driving with a hot engine cooling system could
damage your vehicle. The digital warning light may
switch on (together with a message on the display) to
indicate that the coolant temperature is too high; in this
case, stop the engine and contact a dedicated autho-
rized dealership.WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide
to look under the hood yourself, see “Maintaining
Your Vehicle.” Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
2. Tachometer •This gauge measures engine revolutions per min-
ute (RPM x 1000). Before the pointer reaches the red
area, ease up on the accelerator to prevent engine
damage.
3. Speedometer •Indicates vehicle speed.
4. Fuel Gauge •The digital display shows the amount of fuel in the
tank.
• The switching on of the digital warning light
indicates that 1 – 1.3 gallons of fuel are left in the
tank; in this situation, refuel as soon as possible.

engine fails to start within 10 seconds, turn the ignition
switch to the STOP (OFF/LOCK) position, wait 10 to
15 seconds, then repeat the “Normal Starting” proce-
dure.
Cold Weather Operation
Your engine is designed to operate at temperatures as
low as 0°F (-18°C).
CAUTION!
Use of the recommended SAE 5W-40 Synthetic oil
and adhering to the prescribed oil change intervals
is important to prevent engine damage and ensure
satisfactory starting in cold conditions.
If Engine Fails To Start
WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
CAUTION!
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with a Alfa Twin
Clutch Transmission cannot be started this way.
Unburned fuel could enter the catalytic converter
and once the engine has started, ignite and dam-
age the converter and vehicle.
• To prevent damage to the starter, do not continu-
ously crank the engine for more than 15 seconds
at a time. Wait 10 to 15 seconds before trying
again.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
Turbo Charger “Cool Down”
This vehicle is equipped with an after-run pump to cool
the turbocharger after the engine is shut off. Depending
on the type of driving and the amount of cargo, the
pump will run for up to five minutes after the engine
has been shut off to circulate coolant through the
turbocharger.

STARTING AND OPERATING 135

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

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.

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

MAINTAINING YOUR VEHICLE 225

CAUTION!(Continued)
•Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use addi-
tional rust inhibitors or antirust products, as they
may not be compatible with the engine coolant
and may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (anti-
freeze). Use of propylene glycol-based engine
coolant (antifreeze) is not recommended.
Adding Coolant
Your vehicle has been built with an improved engine
coolant (OAT coolant conforming to MS.90032) that
allows extended maintenance intervals. This engine
coolant (antifreeze) can be used up to ten years or
150,000 miles (240,000 km) before replacement. To pre-
vent reducing this extended maintenance period, it is
important that you use the same engine coolant (OAT
coolant conforming to MS.90032) throughout the life of
your vehicle. Please review these recommendations for using Or-
ganic Additive Technology (OAT) engine coolant (anti-
freeze) that meets the requirements of FCA Material
Standard MS.90032. When adding engine coolant (anti-
freeze):
•
We recommend using MOPAR Antifreeze/Coolant
10 Year/150,000 Mile Formula OAT (Organic Addi-
tive Technology) that meets the requirements of FCA
Material Standard MS.90032.
• Mix a minimum solution of 50% OAT engine coolant
that meets the requirements of FCA Material Stan-
dard MS.90032 and distilled water. Use higher con-
centrations (not to exceed 70%) if temperatures below
34°F (37°C) are anticipated. Please contact your
authorized dealer for assistance.
• Use only high purity water such as distilled or
deionized water when mixing the water/engine
coolant (antifreeze) solution. The use of lower quality
water will reduce the amount of corrosion protection
in the engine cooling system.

MAINTAINING YOUR VEHICLE 227

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
228 MAINTAINING YOUR VEHICLE

remain in puddles on the ground. If ingested by a child
or pet, seek emergency assistance immediately. Clean
up any ground spills immediately.
Coolant Level
The coolant expansion bottle provides a quick visual
method for determining that the coolant level is ad-
equate. With the engine off and cold, the level of the
engine coolant (antifreeze) in the bottle should be
between the “MIN” and “MAX” marks.
As long as the engine operating temperature is satisfac-
tory, the coolant bottle need only be checked once a
month.
When additional engine coolant (antifreeze) is needed
to maintain the proper level, it should be added to the
coolant bottle. Do not overfill.
Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is
normally a result of moisture from rain, snow, or high
humidity accumulating on the radiator and being va-
porized when the thermostat opens, allowing hot en-
gine coolant (antifreeze) to enter the radiator. If an examination of your engine compartment shows
no evidence of radiator or hose leaks, the vehicle may
be safely driven. The vapor will soon dissipate.
•
Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator and in
the coolant expansion bottle. If engine coolant (anti-
freeze) needs to be added, the contents of the coolant
expansion bottle must also be protected against freez-
ing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure
tested for leaks.
• Maintain engine coolant (antifreeze) concentration at
a minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion
protection of your engine which contains aluminum
components.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs
