2018 Alfa Romeo 4C maintenance

•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.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• 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
may result in unsatisfactory engine coolant (anti-
freeze) performance, poor gas mileage, and increased
emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. You would not
have your full braking capacity in an emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately
if the “Brake Warning Light” is on.
Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to bring
the fluid level up to the requirements described on the
brake fluid reservoir. Fluid level can be expected to fall
as the brake pads wear. The brake fluid level should be
checked when the pads are replaced. However, low
fluid level may be caused by a leak and a checkup may
be needed.
212 SERVICING AND MAINTENANCE

Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants ” in “Technical Speci-
fications” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids And Lubricants” in “Tech-
nical Specifications” for further information. Us-
ing the wrong type of brake fluid can severely
damage your brake system and/or impair its per-
formance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
• To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during
hard or prolonged braking, resulting in sudden
brake failure. This could result in a collision.
(Continued)
WARNING! (Continued)
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should
be taken to avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.
CAUTION!
Use of improper brake fluids will affect overall
clutch system performance. Improper brake fluids
may damage the clutch system resulting in loss of
clutch function and the ability to shift the transmis-
sion.

Checking Brake Fluid
To check the brake fluid level, proceed as follows:
1. Loosen the two screws and remove the brake fluidprotection panel. 2. Check that the fluid is at the max. level.
3. After checking, reposition the brake fluid protection
panel and tighten the two screws.

Adding Brake Fluid
If the fluid level in the reservoir is not sufficient,
proceed as follows:
1. Take the black funnel for topping up the brake fluidand its extension pipe from the service kit in the
luggage compartment.
2. Loosen the reservoir plug and introduce the funnel with the extension pipe in the reservoir inlet.
3. After topping up, remove the funnel with the exten- sion pipe.
4. Tighten the reservoir plug. 5. Reposition the brake fluid protection panel and
tighten the two screws.
NOTE: Be very careful while removing the plug from
the opening to prevent the plug from falling inside the
vehicle body.
Alfa Twin Clutch Transmission
Selection Of Lubricant
It is important to use the proper transmission fluid to
ensure optimum transmission performance and life. Use
only the manufacturer ’s specified transmission fluid.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for fluid specifications. It is important to maintain
the transmission fluid at the correct level using the
recommended fluid. No chemical flushes should be used
in any transmission; only the approved lubricant should
be used.
CAUTION!
Using a transmission fluid other than the manufac-
turer ’s recommended fluid may cause deterioration
in transmission shift quality. Refer to “Fluids And
Lubricants” in “Technical Specifications” for fluid
specifications.

Special Additives
The manufacturer strongly recommends against using
any special additives in the transmission.
Transmission fluid is an engineered product and its
performance may be impaired by supplemental addi-
tives. Therefore, do not add any fluid additives to the
transmission. The only exception to this policy is the
use of special dyes for diagnosing fluid leaks.
CAUTION!
Do not use chemical flushes in your transmission as
the chemicals can damage your transmission com-
ponents. Such damage is not covered by the New
Vehicle Limited Warranty.
Fluid Level Check
The fluid level is preset at the factory and does not
require adjustment under normal operating conditions.
Frequent fluid level checks are not required, but have
your authorized dealer check the fluid level as specified
in the Maintenance Schedule to ensure proper transmis-
sion function and longevity. The transmission has no
dipstick, but your authorized dealer can check your
transmission fluid level using special service tools. Ifyou notice fluid leakage or transmission malfunction,
visit your authorized dealer immediately to have the
transmission fluid level checked. Operating the vehicle
with an improper fluid level can cause severe transmis-
sion damage.
Fluid Changes
Under normal operating conditions, the fluid installed
at the factory will provide satisfactory lubrication for
the life of the vehicle. However, change the fluid if it
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
RAISING THE VEHICLE
In the case where it is necessary to raise the vehicle, go
to an authorized dealer or service station.

•P (Passenger) — Metric tire sizing is based on U.S.
design standards. P-Metric tires have the letter “P”
molded into the sidewall preceding the size designa-
tion. Example: P215/65R15 95H.
• European — Metric tire sizing is based on European
design standards. Tires designed to this standard
have the tire size molded into the sidewall beginning
with the section width. The letter Pis absent from
this tire size designation. Example: 215/65R15 96H.
• LT (Light Truck) — Metric tire sizing is based on U.S.
design standards. The size designation for LT-Metric
tires is the same as for P-Metric tires except for the
letters “LT” that are molded into the sidewall preced-
ing the size designation. Example: LT235/85R16.
• Temporary spare tires are designed for temporary
emergency use only. Temporary high pressure com-
pact spare tires have the letter “T” or “S” molded into
the sidewall preceding the size designation. Ex-
ample: T145/80D18 103M.
• High flotation tire sizing is based on U.S. design
standards and it begins with the tire diameter
molded into the sidewall. Example: 31x10.5 R15 LT.
