2018 FIAT FULLBACK radiator

1 – Check depths of a stream and
geographical features before attempting
to cross a stream and ford the stream
where the water is as shallow as
practicable.
2 – Set the drive mode-selector to “4L”
position (Easy Select 4WD), “4LLc”
position (Super Select 4WD II).
3 – Drive slowly at a speed of
approximately 5 km/h to avoid
splashing too much water.

Inspection and maintenance
following rough road operation
After operating the vehicle in rough road
conditions, be sure to perform the
following inspection and maintenance
procedures:
Check that the vehicle has not been
damaged by rocks, gravel, etc.
Carefully wash the vehicle with water.
Drive the vehicle slowly while lightly
depressing the brake pedal in order to
dry out the brakes. If the brakes still do
not function properly, contact a Fiat
Dealership as soon as possible to have
the brakes checked.
Remove the insects, dried grass, etc.
clogging the radiator core and the A/T
oil cooler.
After crossing a stream, be sure to have
the following items inspected at a Fiat
Dealership and take the necessary
measures:
Check the brake system and, if
necessary, have it serviced.
Check the engine, transmission,
transfer, and differential oil or grease
level and turbidity. If the oil or grease is
milky, it indicates water contamination.
Replace it with new oil or grease.
Grease the propeller shaft.
Check the inside of the vehicle. If
ingress of water is found, dry the carpet
etc.
Inspect the headlamps. If the
headlamp bulb is flooded with water,
have the headlamp drained off.
IMPORTANT
144)Selecting “4H” or “4L” position (Easy
Select 4WD), “4HLc” or “4LLc” position
(Super Select 4WD II) to drive on dry paved
road will increase the fuel consumption with
possible noise generation and early tyre
wear. It may also increase the differential oil
temperature, resulting in possible damage
to the driving system. Further, the drive
train will be subjected to excessive loading,
possibly leading to oil leakage, component
seizure, or other serious faults.
145)Avoid sudden braking, sudden
acceleration, and sharp turning; such
operations could cause skidding and
spinouts.146)Do not force the vehicle or drive
recklessly on sandy surfaces. In
comparison with normal road surfaces, the
engine and other drive-system components
are put under excessive strain when driving
on such a surface, and this could lead to
accidents.
147)If any of following conditions occur
while the vehicle is being driven,
immediately park your vehicle in a safe
place and follow these procedures: the
needle in the temperature gauge
approaches the overheating zone. Refer to
“Engine overheating”; automatic
transmission fluid temperature warning
lamp comes on. Refer to “When the A/T
(automatic transmission) fluid temperature
warning lamp comes on”.
148)Never cross a stream where the water
is deep. Do not change gears while
crossing the stream. Frequent crossing of
streams can adversely affect the life span
of the vehicle; we recommend you to take
the necessary measures to prepare,
inspect, and repair the vehicle.
149)After crossing a stream, apply the
brakes to be sure they are functioning
properly. If the brakes are wet and not
functioning properly, dry them out by
driving slowly while lightly depressing the
brake pedal. Inspect each part of the
vehicle carefully.

4. Check the coolant level in the reserve
tank (C).
5. Add coolant to the radiator and/or
reserve tank if necessary (refer to the
“Maintenance” section).

6. Examine the radiator hoses for
coolant leakage and the drive belt for
looseness or damage. If there is
anything wrong with the cooling system
or drive belt, we recommend you to
have it checked and repaired.
WARNING
293)Do not open the bonnet while steam
is coming from the engine compartment. It
could cause steam or hot water to spurt
out, causing burns. Hot water could spurt
out even when there is no steam coming
out, and some parts will be very hot. Be
very careful when opening the bonnet.
294)Be careful of hot steam, which could
be blowing off the reserve tank cap.
295)Do not attempt to remove the radiator
cap while the engine is hot.
296)Be careful not to get your hands or
clothes caught in the cooling fan.
297)Make sure that the engine has cooled
down before removing the radiator cap (A),
because hot steam or boiling water
otherwise will gush from the filler port and
may scald you.
IMPORTANT
165)Do not add coolant while the engine is
hot. Suddenly adding cold coolant could
damage the engine. Wait for the engine to
cool down, then add coolant a little at a
time.
BLEEDING THE FUEL
SYSTEM
The fuel system should be bled to
remove air as described below if the
fuel supply is exhausted during travel.
Pump the hand pump (A) at the top of
the fuel filter until the hand pump
becomes stiff.
Then try again to start the engine. If the
engine does not start, repeat the
process above.
298) 299)
WARNING
298)Do not smoke or have any other open
flame near the vehicle while bleeding the
fuel system.
299)Be sure to carefully clean away any
spilt fuel which could ignite and cause a
fire.

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) and
add coolant until the level reaches the
filler neck.
377) 378)
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.
Above -35 °C: 50 % concentration of
antifreeze
Below -35 °C: 60 % concentration of
antifreeze
183) 184) 185) 186) 187)
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
377)The used engine oil and the filter that
has been replaced contain substances that
are harmful to the environment. To change
the oil and filters, we advise you to contact
a Fiat Dealership.
378)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
183)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.
184)Concentrations exceeding 60 % will
result in a reduction of both the anti-freeze
and cooling performance thus adversely
affecting the engine.
185)Do not top up with water only.
186)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.
187)Do not use water to adjust the
concentration of coolant.
