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 rec-
ommend 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,
remove the radiator cap (C) or the reserve
tank cap (D) and add coolant until the level
reaches the filler neck.
WARNING
l Do not open the radiator cap (C) and the
reserve tank cap (D) while the engine and
the plug-in hybrid EV system are hot. The
coolant system is under pressure and any
hot coolant escaping could cause severe
burns.
Anti-freeze
The engine coolant and the plug-in hybrid
EV system coolant contains an ethylene gly-
col anti-corrosion agent. Some parts of the
engine and the plug-in hybrid EV system are
cast aluminium alloy, and periodic changing
of the engine coolant and the plug-in hybrid
EV system coolant are necessary to prevent
corrosion of these parts.
Use “MITSUBISHI MOTORS GENUINE
SUPER LONG LIFE COOLANT PREMI-
UM” or equivalent
*
.
MITSUBISHI MOTORS GENUINE Coolant
has excellent protection against corrosion and
rust formation of all metals including alumi-
nium and can avoid blockages in the radiator,
heater, cylinder head, engine block, etc.
Because of the necessity of this anti-corro-
sion agent, the coolant must not be replaced
with plain water even in summer. The re-
quired concentration of anti-freeze differs de-
pending on the expected ambient tempera-
ture.
Above -35 °C: 50 % concentration of anti-
freeze
*
similar high quality ethylene glycol based
non-silicate, non-amine, non-nitrate and
non-borate coolant with long life hybrid
organic acid technology
Below -35 °C: 60 % concentration of anti-
freeze
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 im-
proper anti-freeze can cause corrosion of the
aluminium components.
l Do not use water to adjust the concentration
of coolant.
l Concentrations exceeding 60 % will result in
a reduction of both the anti-freeze and cool-
ing performance thus adversely affecting the
engine.
l 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.
During cold weather
If the temperatures in your area drop below
freezing, there is the danger that the coolant
in the engine, plug-in hybrid EV system or
radiator could freeze and cause severe dam-
age to the engine and/or radiator. Add a suffi-
cient amount of anti-freeze to the coolant to
prevent it from freezing.
