To add coolant
Mitsubishi Motors Genuine Coolant provides excellent protec-
tion against corrosion and rust formation on all metals, includ-
ing aluminum, and prevents clogs in some parts of the engine.
If you need to add coolant often, or if the level in the reserve
tank does not drop when the engine cools, the cooling system
should be pressure-tested for leaks. Take your vehicle to an
authorized Mitsubishi Motors dealer or a repair facility of your
choice for testing.
Radiator cap
The radiator cap must be tight sealed to prevent losing coolant,
which may result in engine damage. Only use a Genuine
Mitsubishi Parts radiator cap, or an approved equivalent.
Points to remember
●
Do not overfill the reserve tank.
●
Your vehicle uses a special radiator cap that stays sealed
and lets the coolant flow from the reserve tank back to the
radiator when the engine cools down. If you need to
change the cap, use the exact same kind.
●
Check the coolant freeze point in the radiator with the
proper gauge, and only when it is safe. If you add anti-
freeze, the contents of the reserve tank must be protected
against freezing.
Use “Mitsubishi Motors Genuine Super Long Life Coolant Pre-
mium” or equivalent*.
*: similar high quality ethylene glycol based non-silicate, non-
amine, non-nitrate and non-borate coolant with long life
hybrid organic acid technology
CAUTION
!
●
Do not use alcohol or methanol antifreeze or any
engine coolants that contain them. Using the wrong
antifreeze can corrode aluminum parts.
●
The required concentration of anti-freeze differs
depending on the expected ambient temperature.
Above -31
°
F (-35
°
C) : 50 % concentration of anti-
freeze
Below -31
°
F (-35
°
C) : 60 % concentration of anti-
freeze
You can check the concentration level with a gauge
from an automotive supply store, or your authorized
Mitsubishi Motors dealer or service station can
check it for you.
●
Do not use water to adjust the concentration of cool-
ant.
●
Do not top off the tank with plain water only. Water
by itself boils at a lower temperature and does not
stop rust or freezing. If the water freezes, it will
damage your cooling system. Do not use tapwater. It
can cause corrosion and rust.
WARNING
!
●
Wait for the engine to cool down before opening the
radiator cap. Otherwise hot steam or boiling coolant
could spray up from the radiator and scald you.
