A translucent 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.
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 authorised
MITSUBISHI MOTORS dealer 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.
The engine coolant contains an ethylene gly-
col 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.
MITSUBISHI MOTORS GENUINE Coolant
has excellent protection against corrosion and
rust formation of all metals including alumin-
ium 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.

WARNING
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.

CAUTION
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 alu-
minium components.
Do not use water to adjust the concentration
of coolant.
Concentrations exceeding 60 % will result in
a reduction of both the anti-freeze and cool-
ing performance thus adversely affecting the
engine.
