2004 MITSUBISHI L200 radiator cap

FOR EMERGENCIES
2. With the engine still running, raise the
bonnet to ventilate the engine com-
partment.
A - Radiator fan
B - Radiator cap
C - Reserve tank
NOTE
Confirm that the radiator fan is turning. If
the fan is not turning, stop the engine im-
mediately and contact an authorized
MITSUBISHI dealer for assistance.
WARNING
(1) Remember that under the bon-
net, there can be boiling water
gushing out or the support bar
could be burning hot. If the
bonnet is opened suddenly, you
could get burnt.
(2) Be careful of hot steam which
could be blowing off the reserve
tank cap.
(3) Do not attempt to remove the
radiator cap while the engine is
hot.
3. After the engine coolant temperature
has dropped to the normal tempera-
ture, stop the engine.

FOR EMERGENCIES
4. Check the coolant level in the reserve
tank. If there is none, make sure that
the engine has cooled down before
removing the radiator cap, because
hot steam or boiling water otherwise
will gush from the filler port and may
scald you.
5. Add coolant to the radiator and/or
reserve tank if necessary (refer to the
“Maintenance” section).
CAUTIONAdding cold water rapidly when the
engine is hot could cause the cylin-
der head and/or block to crack, add
the water a little at a time while run-
ning the engine.
Bleeding the fuel system
(diesel-powered vehicles
only)
EN07A-La
The fuel system should be bled to remove
air as described below if the fuel supply is
exhausted during travel.
1. Loosen the air plug (A) at the top of
the fuel filter. 6. Examine the radiator hoses for
coolant leakage and the fan belts for
looseness or damage.
If there is anything wrong with the
cooling system or fan belt, have the
problem corrected at an authorized
MITSUBISHI dealer.

Engine coolantEM36A-Gg
A translucent coolant reserve tank is lo-
cated in the engine compartment. The
coolant level in this tank should be kept
between the “LOW” and “FULL” marks
when measured while the engine is cold.
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, have the system checked at an
authorized MITSUBISHI dealer 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, remove the radiator cap and add
coolant until the level reaches the filler
neck.
MAINTENANCE
CAUTION(1) 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 the corrosion of the alu-
minium components.
(2) 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 per-
formance thus adversely affect-
ing the engine.
(3) Do not top up with water only.
Water by itself reduces the rust-
protective and anti-freeze qual-
ities 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, or it causes the
corrosion and rust formation.
CAUTIONDo not open the radiator cap while
the engine is hot. The coolant sys-
tem 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 prevent
corrosion of these parts.
Use MITSUBISHI Genuine Coolant or an
equivalent.
MITSUBISHI Genuine Coolant has excel-
lent protection against corrosion and rust
formation of all metals including alu-
minium and can avoid clogs in the radia-
tor, 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.

MAINTENANCE
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 anti-freeze to the coolant to
prevent it from freezing.
The engine coolant mixture used at the
factory provides protection against freez-
ing for temperatures as low as approxim-
ately –30°C. The concentration should be
checked before the start of cold weather
and anti-freeze added to the system if
necessary.BatteryEM37APD
The condition of the battery is very impor-
tant for quick starting of the engine and
proper functioning of the vehicle’s elec-
trical system. Regular inspection and care
are especially important in cold weather.
NOTE
(1) After replacing the battery, the elec-
tronic control system data for the en-
gine, automatic transmission, etc., will
be erased.
As a result, the engine speed may be-
come unstable and shift shocks may
occur.
If the engine speed becomes unsta-
ble, initial engine adjustments will
need to be performed.
Refer to the section “What to do if the
engine speed becomes unstable after
the battery is replaced” on page 8-30.
Shift shocks will become smoother af-
ter several changes in speed.
(2) Memory data for settings made by the
user may be erased when the battery
is replaced. If this happens, establish
the settings again using the relevant
procedures.
Checking battery electrolyte level
Type 1
The electrolyte level must be between the
specified limit marks stamped on the out-
side 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 up-
per mark. Do not over-replenish beyond
the upper mark because spillage during
driving could cause damage.
Check the electrolyte level at least once
every four weeks, depending on the oper-
ating 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.
