2016 FIAT FULLBACK coolant temperature

engine coolant temperature is low. In
such a case, the engine revolutions do
not rise to over 5,000 rpm even if the
accelerator pedal is depressed.
Starting the engine (diesel-powered
vehicles)
Except for vehicles equipped with
the keyless operation system
Insert the ignition key and fasten the
seat belt.
Make sure the parking brake is
applied.
Depress and hold the brake pedal.
On vehicles equipped with M/T,
depress the clutch pedal all the way
and place the gearshift lever in the “N”
(Neutral) position. On vehicles equipped
with A/T, make sure the selector lever is
in the “P” (PARK) position.
Turn the ignition key to the “ON”
position. The diesel preheat indicator
lamp will first illuminate, and then after a
short time go out, indicating that
preheating is completed.
Turn the ignition key to the “START”
position without depressing the
accelerator pedal, and release it when
the engine starts.If the engine is cold, the diesel preheat
indicator lamp is on for a longer time.
When the engine has not been started
within about 5 seconds after the diesel
preheat indicator lamp went out, return
the ignition switch to the “LOCK”
position. Then, turn the switch to the
“ON” position to preheat the engine
again.
When the engine is warm, the diesel
preheat indicator lamp does not come
on even if the ignition key is placed in
the “ON” position. Start the engine by
turning the ignition key right to the
“START” position.
Minor noises may be heard on engine
startup. These will disappear as the
engine warms up.For vehicles equipped with the
keyless operation system
Fasten the seat belt.
Make sure the parking brake is
applied.
Press and hold the brake pedal
down firmly with your right foot.
On vehicles equipped with M/T,
depress the clutch pedal all the way
and place the gearshift lever in the “N”

Press the engine switch. The diesel
preheat indicator lamp will first
illuminate, and then after a short time
go out, indicating that preheating is
completed. The engine will start.
When the engine is not started, it may
become hard to depress the brake
pedal and the vehicle may not be able
to detect the pedal operation. Therefore
the engine may not be started. In such
a case, depress the brake pedal more
firmly than usual.
If the engine is cold, the diesel preheat
indicator lamp is on for a longer time.
Putting the operation mode in ON will
also start preheating the engine. When

ENGINE
OVERHEATING
When the engine is overheating,will
blink. If this occurs, take the following
corrective measures:
1. Stop the vehicle in a safe place.
2. Check whether steam is coming from
the engine compartment.
If steam does not come from the engine
compartment: with the engine still
running, raise the bonnet to ventilate
the engine compartment.
If steam is coming from the engine
compartment: stop the engine, and
when the steam stops, raise the bonnet
to ventilate the engine compartment.
Restart the engine.
248) 249) 250)
3. Confirm that the cooling fan (B) is
turning.
If the cooling fan is turning: after the
high coolant temperature warning has
gone off, stop the engine
If the cooling fan is not turning: stop the
engine immediately and contact a Fiat
dealership for assistance.A — Radiator cap
B — Cooling fan
C — Reserve tank
251)
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).
252)
131)
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, have the
problem corrected at a Fiat Dealership.
WARNING
248)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.
249)Be careful of hot steam, which could
be blowing off the reserve tank cap.
250)Do not attempt to remove the radiator
cap while the engine is hot.
251)Be careful not to get your hands or
clothes caught in the cooling fan.
252)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.

PERIODIC CHECKS
Before long journeys, check and, if
necessary, restore:
engine coolant level;
brake fluid level;
windscreen washer fluid level;
operation of lighting system
(headlamps, direction indicators, hazard
warning lights, etc.);
tyre inflation pressure and condition;
tyre alignment;
operation of screen washer/wiper
system and positioning/wear of
windscreen/rear window wiper blades.
To ensure that the vehicle is always
efficient and well maintained, it is
advisable to make sure that you carry
out the above operations regularly
(approximately every 1000 km and
every 3000 km for checking and
topping up engine oil is advisable).
DEMANDING

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.
