cooling MITSUBISHI PAJERO IV 2011 Owners Manual

CAUTION
l
Normally, use the outside position to keep
the windscreen and
side windows clear
and quickly remove fog or frost from the
windscreen.
If high cooling performance is desired, or
if the outside air is dusty or otherwise con-
taminated use the recirculation position.
Switch to the outside position periodically
to increase ventilation so that the win-
dows do not become fogged up.
l Use of the recirculation position for exten-
ded time may cause the windows to fog up.
NOTE l If
you press

the AUTO switch to select auto-
matic control after manually switching be-
tween outside air and recirculated air, the air
selection will also be automatically controlled. AUTO switch

NOTE l If
a problem

is detected in the air condition-
ing compressor, the air conditioning opera-
tion indication lamp (A) blinks. Stop the ve-
hicle in a safe place, turn off the engine, then
restart the engine. If the air conditioning op-
eration indication lamp does not blink, there
is no problem. If it does blink, we recom-
mend you to have it checked.
l Sometimes, for example after using a high-
pressure car wash, the condenser can get wet,
and the operation indication lamp (A) blinks
temporarily. In this case there is nothing
wrong. Stop the vehicle in a safe place, turn
off the engine, then restart the engine. Once
the water evaporates, the blinking will stop. For pleasant driving

Always switch the front air conditioning com-
pressor on before using the rear air condition-
ing. If the front air conditioning compressor
is not operating, the system will just operate
as a blower. Important operation tips for the
air conditioning E00708300889
l Park the vehicle in the shade.
Parking
in
the
hot sun will make the vehicle
inside extremely hot, and it will require more
time to cool the interior.
If it is necessary to park in the sun, open the
windows for the first few minutes of air con-
ditioning operation to expel the hot air.
l Close the windows when the air conditioning
is in use. The entry of outside air through
open windows will reduce the cooling effi-
ciency.
l Too much cooling is not good for the health.
The inside air temperature should only be 5
to 6 °C below the outside air temperature.
l When operating the system, make sure the
air intake, which is located in front of the
windscreen, is free of obstructions such as
leaves and snow. Leaves collected in the air-
intake plenum may reduce air flow and plug
the plenum water drains.
Air conditioning system refrigerant
and lubricant recommendations
If the air conditioning seems less effective than usu-
al, the cause might be a refrigerant leak. We recom-
mend you to have the system inspected.
The air conditioning system in your vehicle must
be charged with the refrigerant HFC-134a and the
lubricant ND-OIL8.
Use of any other refrigerant or lubricant will cause
severe damage which will result in the need to re-
place your vehicle’s entire air conditioning system.
The release of refrigerant into the atmosphere
should be prevented. For pleasant 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
E01000700656
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
