check engine FIAT FULLBACK 2016 1.G Workshop Manual

The engine oil used has a significant
effect on the engine’s performance,
service life and startability. Be sure to
use oil of the recommended quality and
appropriate viscosity. All engines
consume a certain amount of oil during
normal operation. Therefore, it is
important to check the oil level at
regular intervals or before starting a
long trip.
1. Park the car on a horizontal surface.
2. Switch off the engine.
3.Wait a few minutes.
4. Remove the dipstick and wipe it with
a clean cloth.
5. Reinsert the dipstick as far as it
goes.
6. Remove the dipstick and read the oil
level, which should always be within the
range indicated.
7. If the oil level is below the specified
limit, remove the cap located on the
cylinder head cover and add enough oilto raise the level to within the specified
range. Do not overfill to avoid engine
damage. Be sure to use the specified
engine oil and do not mix various types
of oil.
8. After adding oil, close the cap
securely.
9. Confirm the oil level by repeating
step 4 to 6.
NOTE Check or refill the oil according
to the following manner.
When the oil level is checked in step
6 above, check it on a low side of the
dipstick because it is different in
appearance of oil level in the two sides
of the dipstick.
On vehicles without diesel particulate
filter (DPF), the oil level should be within
the range (A) to (B) on the dipstick.
On vehicles with DPF, the oil level
should be within the range (A) to (C) (oil
replacement indication mark) on the
dipstick. If the oil level is beyond the oil
replacement indication mark (C),
replace the oil as soon as possible.
Then, the oil should be refilled to the
maximum level (B).
On vehicle with DPF, the engine oil
will be increased due to a few of the
fuel gets mixed in the engine oil when
the DPF regenerates to burn away the
PM (particulate matter). However, it
does not indicate a malfunction.
The engine oil will deteriorate rapidly ifthe vehicle is subjected to severe
conditions, requiring earlier oil
replacement. Please refer to the
maintenance schedule.
Selection of engine oil —
Petrol-powered and Diesel-
powered vehicles
Refer to “Refill capacities” under
Technical Specifications.
WARNING
315)If the engine oil is being topped up,
wait for the engine to cool down before
loosening the filler cap, particularly for
vehicles with aluminium cap (where
provided). WARNING: risk of burns!

SERVICING AND MAINTENANCE

ENGINE COOLANT
To check the coolant level
A transparent coolant reserve tank (A) is
located in the engine compartment. The
coolant level in this tank should be kept
between the “L” (LOW) and “F” (FULL)
marks when measured while the engine
is cold.
To add coolant
The cooling system is a closed system
and normally the loss of coolant should
be very slight. A noticeable drop in the
coolant level could indicate leakage. If
this occurs, we recommend you to
have the system checked as soon as
possible. If the level should drop below
the “L” (LOW) level on the reserve tank,
open the lid and add coolant.
Also, if the reserve tank is completely
empty, remove the radiator cap (B) andadd coolant until the level reaches the
filler neck.316)
Anti-freeze
The engine coolant contains an
ethylene glycol anti-corrosion agent.
Some parts of the engine are cast
aluminium alloy, and periodic changing
of the engine coolant is necessary to
prevent corrosion of these parts.
Use the recommended coolant by Fiat
or equivalent*. *: similar high quality
ethylene glycol based non-silicate,
non-amine, nonnitrate and nonborate
coolant with long life hybrid organic
acid technology Fiat genuine coolant
has excellent protection against
corrosion and rust formation of all
metals including aluminium and can
avoid blockages in the radiator, heater,
cylinder head, engine block, etc.
Because of the necessity of this
anti-corrosion agent, the coolant must
not be replaced with plain water even in
summer. The required concentration of
anti-freeze differs depending on the
expected ambient temperature.

During cold weather
If the temperatures in your area drop below freezing, there is the danger that the coolant in the engine or radiator could freeze
and cause severe damage to the engine and/or radiator. Add a sufficient amount of antifreeze to the coolant to prevent it from
freezing.
The concentration should be checked before the start of cold weather and anti-freeze added to the system if necessary.
WARNING
316)Do not open the radiator cap (B) while
the engine is hot. The coolant system is
under pressure and any hot coolant
escaping could cause severe burns.
IMPORTANT
148)Do not use alcohol or methanol
anti-freeze or any engine coolants mixed
with alcohol or methanol anti-freeze. The
use of an improper anti-freeze can cause
corrosion of the aluminium components.149)For effective anti-corrosion and
anti-freeze performance, keep the
anti-freeze concentration within the range
of 30 to 60 %. Concentrations exceeding
60 % will result in a reduction of both the
anti-freeze and cooling performance thus
adversely affecting the engine.
150)Do not top up with water only. Water
by itself reduces the rust-protective and
anti-freeze qualities of the coolant and has
a lower boiling point. It can also cause
damage to the cooling system if it should
freeze. Do not use tapwater, as it can
cause corrosion and rust formation.151)PARAFLU UP anti-freeze is used in
the engine cooling system. Use fluid of the
same type as that contained in the cooling
system for any top-ups. PARAFLU UP
cannot be mixed with any other type of
fluid. If this happens, do not start the
engine under any circumstances and
contact a Fiat Dealership.

SERVICING AND MAINTENANCE

WASHER FLUID
Open the washer fluid reservoir cap and
check the level of washer fluid with the
dipstick. If the level is low, replenish the
container with washer fluid.
NOTE The washer fluid container
server serves the windscreen and
headlamps (if so equipped).
During cold weather
To ensure proper operation of the
washers at low temperatures, use a
fluid containing an anti-freezing agent.
317) 318)
WARNING
317)Do not travel if the windscreen
washer reservoir is empty: using the
windscreen washer is essential for
improving visibility. Repeated operation of
the system without fluid could damage or
cause rapid deterioration of some system
components.
318)Some commercial additives for
windscreen washer fluid are flammable.
The engine compartment contains hot
components which may start a fire.
BRAKE FLUID
To check the fluid level
Check the brake fluid level in the
reservoir. The brake fluid level must be
between the “MAX” and “MIN” marks
on the reservoir.
The brake fluid level is monitored by a
float. When the brake fluid level falls
below the “MIN” mark, the brake fluid
warning lamp lights up.
The fluid level falls slightly with wear of
the brake pads, but this does not
indicate any abnormality.
If the brake fluid level falls markedly in a
short length of time, it indicates leaks
from the brake system. If this occurs,
we recommend you to have the vehicle
checked.

To check the fluid level
Check the fluid level in the reservoir
while the engine is idling. Check to
make certain that the power steering
fluid level is always between the “MAX”
and “MIN” level markings on the fluid
reservoir and refill the fluid, if necessary.
WARNING
324)Prevent power steering fluid from
coming into contact with hot engine parts:
it is flammable.
IMPORTANT
3)Power steering fluid consumption is
extremely low; if another top-up is required
after only a short period of time, have the
system checked for leaks at a Fiat
Dealership.

BATTERY
155) 156)
4)
The condition of the battery is very
important for quick starting of the
engine and proper functioning of the
vehicle’s electrical system. Regular
inspection and care are especially
important in cold weather.

Checking battery electrolyte level
The electrolyte level must be between
the specified limit on the outside of the
battery. Replenish with distilled water as
necessary. The inside of the battery is
divided into several compartments;
remove the cap from each
compartment and fill to the upper mark.
Do not top up beyond the upper markbecause spillage during driving could
cause damage.
Check the electrolyte level at least once
every four weeks, depending on the
operating conditions. If the battery is
not used, it will discharge by itself with
time.
Check it once every four weeks and
charge with low current as necessary.
During cold weather
The capacity of the battery is reduced
at low temperatures. This is an
inevitable result of its chemical and
physical properties. This is why a very
cold battery, particularly one that is not
fully charged will only deliver a fraction
of the starter current which is normally
available.
We recommend you to have the battery
checked before the start of cold
weather and, if necessary, have it
charged or replaced. This does not only
ensure reliable starting, but a battery
which is kept fully charged also has a
longer life.
Disconnection and connection
157) 158) 159) 160)
To disconnect the battery cable, stop
the engine, first disconnect the negative
(-) terminal and then the positive (+)
terminal. When connecting the battery,
first connect the positive (+) terminal
and then the negative (-) terminal.NOTE Open the terminal cover (A)
before disconnecting or connecting the
positive (+) terminal of the battery.
NOTE Loosen the nut (B), and then
disconnect the battery cable from the
positive (+) terminal.
NOTE Keep the terminals clean. After
the battery is connected, apply terminal
protection grease. To clean the
terminals, use lukewarm water.
NOTE Check to see if the battery is
securely installed and cannot be moved
during travel. Also check each terminal
for tightness.
NOTE When the vehicle is to be left
unused for a long period of time,
remove the battery and store it in a
place where the battery fluid will not
freeze. The battery should be stored
only in a fully charged condition.
