maintenance Alfa Romeo 4C 2018 Owner's Guide

WARNING!
The air induction system (air cleaner, hoses, etc.)
can provide a measure of protection in the case of
engine backfire. Do not remove the air induction
system (air cleaner, hoses, etc.) unless such removal
is necessary for repair or maintenance. Make sure
that no one is near the engine compartment before
starting the vehicle with the air induction system
(air cleaner, hoses, etc.) removed. Failure to do so
can result in serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. Mopar engine air
cleaner filters are a high quality filter and are recom-
mended.
Engine Cover
To avoid possible damage to the engine cover, please
disconnect each of the four mounting studs by pulling
the engine cover upward, and then lift off the complete cover. Tilting the engine cover when one or more studs
are still engaged will lead to premature failure of the
couplers.
To reassemble the cover back onto the engine, first make
sure it is properly aligned, the oil cap is centered, and
that all four studs are lined up with their couplers. Then
gently push on the four corners of the engine cover to
snap the stud back into position.
No tools are required to remove or reassemble the
engine cover.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and a perfor-
mance test. Drive belt tension should also be checked at
this time.
WARNING!
•
Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are

flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer
to Warranty Information Book, for further war-
ranty information.
• The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refriger-
ant or any repair requiring lines to be discon-
nected should be done by an experienced techni-
cian.
CAUTION!
Do not use chemical flushes in your air condition-
ing system as the chemicals can damage your air
conditioning components. Such damage is not cov-
ered by the New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling — R–1234yf
R–1234yf Air Conditioning Refrigerant is a hydrofluo-
roolefin (HFO) that is endorsed by the Environmental
Protection Agency and is an ozone-friendly substance with a low global-warming potential. The manufacturer
recommends that air conditioning service be performed
by an authorized dealer using recovery and recycling
equipment.
NOTE:
Use only manufacturer approved A/C system
PAG compressor oil, and refrigerants.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as Mopar Spray White Lube to assure quiet, easy
operation and to protect against rust and wear. Prior to
the application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit; after
lubricating excess oil and grease should be removed.
Particular attention should also be given to hood latch-
ing components to ensure proper function. When per-
forming other underhood services, the hood latch,
release mechanism and safety catch should be cleaned
and lubricated.
The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small

amount of a high quality lubricant, such as Mopar Lock
Cylinder Lubricant directly into the lock cylinder.
Wiper Blades
Clean the rubber edges of the wiper blades, the wind-
shield, and rear window periodically with a sponge or
soft cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt, waxes, or road film, and
help reduce streaking and smearing.
Operation of the wipers on dry glass for long periods
may cause deterioration of the wiper blades. Always
use washer fluid when using the wipers to remove salt
or dirt from a dry windshield or rear window.
Avoid using the wiper blades to remove frost or ice from
the windshield or rear window. Make sure that they are
not frozen to the glass before turning them on to avoid
damaging the blade. Keep the wiper blade out of contact
with petroleum products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depend-
ing on geographical area and frequency of use. Poor
performance of blades may be present with chattering,
marks, water lines, or wet spots. If any of these condi-
tions are present, clean the wiper blades or replace as
necessary.
Blade Lifting
If it is necessary to lift the blade from the windshield (In
the event of snow or blade replacement) Proceed as
directed:
1. Rotate the end of the multifunction lever to the OFF position.
2. Turn the ignition to the MAR-ON position then to STOP.
3. After turning the ignition to the STOP, within two minutes move the right stalk upward, into the un-
stable (“anti-panic”) position, for at least half of a

second. The windshield wiper then executes part of a
stroke; at each command, approximately 1/3 of a
normal wiper stroke is triggered.
NOTE: The previous operation can be repeated up to
three times. In order to move the blades to the most
suitable position.
4. Lift the blade from the windshield and proceed with the required operation.
5. Carefully lower the blade, bringing it back in contact with the windshield.
6. Bring the blade to the initial rest position, turning the ignition to MAR-ON.
NOTE: Do not operate the screen wiper with the blades
lifted from the windshield.
Front Wiper Blade Removal/Installation
1. Lift the front wiper arm upward to raise the wiper blade off of the windshield.
2. Push the release button on the arm of the wiper blade.
3. Push the wiper blade up and remove it. 4. Install the wiper blade and firmly push the wiper
blade until it snaps into place.Windshield Washer Nozzles

If there is not a jet of fluid, first check that there is fluid
in the washer reservoir. Refer to “Adding Washer
Solvent” in this chapter for further information.
Then check that the nozzle holes are not clogged; use a
suitable tool such as a needle to unblock them if
necessary.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine ex-
haust system.
If you notice a change in the sound of the exhaust
system; or if the exhaust fumes can be detected inside
the vehicle; or when the underside or rear of the vehicle
is damaged; have an authorized technician inspect the
complete exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit exhaust
fumes to seep into the passenger compartment. In
addition, have the exhaust system inspected each time
the vehicle is raised for lubrication or oil change.
Replace as required.
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. To avoid breath-
ing CO, refer to “Safety Tips” in “Safety” for
further information.
• 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.
CAUTION!
• The catalytic converter requires the use of un-
leaded fuel only. Leaded gasoline will destroy the
effectiveness of the catalyst as an emissions con-
trol device and may seriously reduce engine per-
formance and cause serious damage to the engine.
• Damage to the catalytic converter can result if
your vehicle is not kept in proper operating

CAUTION!(Continued)
condition. In the event of engine malfunction,
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 dam-
age to the converter and vehicle.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is
important to keep the engine properly tuned to assure
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 specifi-
cations, 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 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.

SERVICING AND MAINTENANCE 207

WARNING!(Continued)
•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.
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 (anti-
freeze). 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 local authorized dealer.
If the engine coolant (antifreeze) is dirty or contains
visible sediment, have an authorized dealer clean and
flush with OAT coolant (antifreeze) (conforming to
MS.90032).
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifi-
cations” for further information.
208 SERVICING AND MAINTENANCE

NOTE:
•Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) engine
coolant (antifreeze), may result in engine damage
and may decrease corrosion protection. Organic Ad-
ditive Technology (OAT) engine coolant is different
and should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant (anti-
freeze) or any “globally compatible” coolant (anti-
freeze). If a non-OAT engine coolant (antifreeze) is
introduced into the cooling system in an emergency,
the cooling system will need to be drained, flushed,
and refilled with fresh OAT coolant (conforming to
MS.90032), by an authorized dealer as soon as pos-
sible.
• Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the radiator engine coolant and
may plug the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycolbased engine coolant (anti-
freeze) is not recommended. •
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.
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 (240,000 km) Formula OAT (Or-
ganic Additive Technology) that meets the require-
ments of FCA Material Standard MS.90032.

SERVICING AND MAINTENANCE 209

•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 an
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.
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 a
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 expansion bottle/recovery tank if so equipped.
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.

210 SERVICING AND MAINTENANCE

WARNING!(Continued)
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
engine damage may result.
Disposal Of Used Coolant
Used ethylene glycol-based 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
coolant in open containers or allow it to 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.
