radiator MITSUBISHI PAJERO IV 2011 Owners Manual

Inspection and maintenance
following rough road operation E00606700048
After operating the
vehicle in rough road condi-
tions, be sure to perform the following inspection
and maintenance procedures:
l Check that the vehicle has not been damaged
by rocks, gravel, etc.
l Carefully wash the vehicle with water.
After washing, drive the vehicle slowly
while lightly depressing the brake pedal in or-
der to dry out the brakes. If the brakes still
do not function properly, we recommend you
to have the brakes checked as soon as possible
l Remove the insects, dried grass, etc. clog-
ging the radiator core.
l After crossing a stream, be sure to have the
following items inspected at a MITSUBISHI
MOTORS Authorized Service Point 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 tur-
bidity. If the oil or grease is milky, it indi-
cates 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, we recom-
mend you to have it drained. Cautions on handling of 4-wheel
drive vehicles E00606800401
Tyres and wheels
Since the driving
torque can be applied to the 4
wheels, the performance of the vehicle when oper-
ating in 4-wheel drive is greatly affected by the con-
dition of the tyres.

Pay close attention to the tyres.
l Install specified tyres on all wheels. Refer to
“Tyres and wheels” on page 9-12.
l Be sure to fit all 4 tyres and wheels of the
same size and type.
When replacement of any of the tyres or
wheels is necessary, replace all of them.
l All tyres should be rotated whenever the
wear difference between the front and rear
tyres is recognizable.

Good vehicle performance cannot be expected if
there is a difference in wear between tyres. Refer to
“Tyre rotation” on page 8-14. l Check the tyre inflation pressure regularly.
l If the tyre inflation pressure is inappropriate,
the transfer gear may make some noise and
shock while changing the drive mode. CAUTION
l
Always use tyres
of the same size, same
type, and same brand, and which have no
wear differences. Using tyres which differ
in size, type, brand or the degree of wear
will cause excessive loading, resulting in
possible damage to the drive system.
Towing
If towing is

necessary, we recommend you to have
it done by your MITSUBISHI MOTORS Author-
ized Service Point or a commercial tow truck service.
In the following cases, transport the vehicle using a
tow truck.
l The engine runs but the vehicle does not
move or abnormal noise is produced.
l Inspection of the vehicle’s underside reveals
that oil or some other fluid is leaking.
Only when you cannot receive a towing service
from a MITSUBISHI MOTORS Authorized Serv-
ice Point or commercial tow truck service, tow
your vehicle carefully in accordance with the in-
structions given in “Towing” on page 6-15. Starting and driving

CAUTION
l
Take care not to get the jumper cable
caught in the cooling fan or other rotat-
ing part in the engine compartment.
l Use the proper cables suitable for the bat-
tery size to prevent overheating of the ca-
bles.
l Check the jumper cables for damage and
corrosion before use.
7. Start the engine in the vehicle which has the
booster battery,

let the engine idle a few mi-
nutes, then start the engine in the vehicle
with the discharged battery. CAUTION
l
Keep the engine
of the vehicle giving assis-
tance running.
8. After the engine is started, disconnect the ca-
bles in

the reverse order and keep the engine
running for several minutes. WARNING
l If the
battery
has to be charged while fit-
ted in the vehicle, disconnect the vehicle
side negative (-) terminal connected to the
battery.
l Keep sparks, cigarettes and flames away
from the battery because the battery may
produce an explosion.
l Use adequate ventilation when charging
or using the battery in an enclosed space. WARNING
l Remove all the
caps before charging the
battery.
l Electrolyte is corrosive diluted sulphuric
acid. If electrolyte (battery acid) comes in-
to contact with your hands, eyes, clothes
and the painted surface of your vehicle, it
should be thoroughly flushed with water.
If electrolyte gets in your eyes, flush them
with water immediately and thoroughly,
and get prompt medical attention.
NOTE l If
the vehicle

is put in motion without fully
charging the battery, it might cause the loss
of smooth engine operation and the anti-lock
brake warning lamp to illuminate. Refer to
“Anti-lock brake system (ABS)” on page
4-39. Engine overheating
E00800600991
If the water

temperature gauge indication remains
in the overheating zone for a long time, the engine
may be overheating. If this occurs, take the follow-
ing corrective measures: 1. Stop the vehicle in a safe place.
2. Check whether steam is coming from the en-gine compartment.

[If steam does not come from the engine com-
partment]
With the engine still running, raise the bon-
net to ventilate the engine compartment.

[If steam is coming from the engine compart-
ment]
Stop the engine, and when the steam stops,
raise the bonnet to ventilate the engine com-
partment. Restart the engine. WARNING
l Do not
open
the bonnet while steam is com-
ing 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.
l Be careful of hot steam, which could be
blowing off the reserve tank cap.
l Do not attempt to remove the radiator
cap while the engine is hot. For emergencies

3. Confirm that the cooling fan is turning. If the
fan is not turning, stop the engine immediate-
ly and have it checked.Front A- Radiator cap
B- Cooling fan
C- Reserve tank
* : If so equipped WARNING
l Be careful
not
to get your hands or
clothes caught in the cooling fan. 4. After the engine coolant temperature has drop-
ped to

the normal temperature, stop the engine. 5. Check the coolant level in the reserve tank (A).
WARNING
l If there
is
none, make sure that the en-
gine has cooled down before removing
the radiator cap (B), because hot steam
or boiling water otherwise will gush from
the filler port and may scald you. 6. Add coolant to the radiator and/or reserve
tank if

necessary. (Refer to the “Mainte-
nance” section.) CAUTION
l
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.
7. Examine the radiator hoses for coolant leak-
age 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. For emergencies

NOTE
l Use
of additives
is not recommended since
they may reduce the effectiveness of addi-
tives already included in the engine oil. It
may result in failure of the mechanical assem-
bly.
Vehicles with diesel particulate filter (DPF) l
Select engine
oil
of the proper SAE viscosity
number according to the atmospheric temper-
ature.
l Use engine oil conforming to the following
classification:
• ACEA classification:“For service C1, C2, C3 or C4”
• JASO classification: “For service DL-1”
If those classifications are not available, con-
tact a MITSUBISHI MOTORS Authorized
Service Point. NOTE
l Use
of additives

is not recommended since
they may reduce the effectiveness of addi-
tives already included in the engine oil. It
may result in failure of the mechanical assem-
bly. Engine coolant
E01000501273
To check the coolant level
A translucent
coolant
reserve tank is located in the
engine compartment.
The coolant level in this tank should be kept be-
tween the “LOW” and “FULL” marks when meas-
ured while the engine is cold. To add coolant
The cooling
system

is a closed system and normal-
ly the loss of coolant should be very slight. A no-
ticeable drop in the coolant level could indicate leak-
age. If this occurs, we recommend you to have the
system checked as soon as possible.
If the level should drop below the “LOW” level on
the reserve tank, open the lid and add coolant.
Also, if the reserve tank is completely empty, re-
move the radiator cap and add coolant until the lev-
el reaches the filler neck. Maintenance

WARNING
l Do not open the radiator cap while the en-
gine is hot.
The coolant system is under pressure and
any hot coolant escaping could cause se-
vere burns.
Anti-freeze
The engine coolant

contains an ethylene glycol anti-
corrosion agent. The cylinder head and water pump
housing are cast aluminium alloy, and periodic
changing of the engine coolant is necessary to pre-
vent corrosion of these parts.

Use “DIA QUEEN SUPER LONG LIFE COOL-
ANT” or equivalent.
MITSUBISHI Genuine Coolant has excellent pro-
tection against corrosion and rust formation of all
metals including aluminium and can avoid block-
ages 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 am-
bient temperature. Ambient
temperature (mini-
mum) °C -15 -20 -25 -30 -35 -50 Anti-freeze
concentra- tion % 30 35 40 45 50 60 CAUTION
l
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 cor-
rosion of the aluminium components.
l For effective anti-corrosion and anti-
freeze performance, keep the anti-freeze
concentration within the range of 30 to
60 %.
Concentrations exceeding 60 % will re-
sult in a reduction of both the anti-freeze
and cooling performance thus adversely
affecting the engine.
l Do not top up with water only.
During cold weather
The concentration should

be checked before the
start of cold weather and anti-freeze added to the
system if necessary to prevent damage to engine
and radiator due to freezing. Washer fluid

Windscreen washer fluid
The windscreen washer

fluid reservoir is in the en-
gine compartment.
Check the washer fluid level at regular intervals
and add washer fluid to reservoir if necessary. NOTE
l The
washer fluid

container serves the wind-
screen and headlamps (if so equipped). Maintenance
