To add coolant
N00955900011
Mitsubishi Genuine Coolant provides excellent protection
against corrosion and rust formation on all metals, including
aluminum.
If you need to add coolant often, the cooling system should be
pressure-tested for leaks. Take your vehicle to a certified i-
MiEV dealer for testing.
Reservoir cap
N00955800010
The reservoir cap (E) must be tightly sealed to prevent losing
coolant which may result in electric motor or nearby parts of
the room under the hood damage. Only use a Genuine
Mitsubishi Parts reservoir cap, or an approved equivalent.
Use “Dia Queen Super Long Life Coolant Premium” or an
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
coolants that contain them. Using the wrong anti-
freeze 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 a certified i-
MiEV 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 tap water. It
can cause corrosion and rust.
WARNING
!
Wait for the electric motor to cool down before
opening the reservoir cap. Otherwise hot steam or
boiling coolant could spray up from the reservoir
and scald you.
