6. When you do not see any more steam or spray, open the
hood. Look for obvious leaks, such as a split radiator
hose. Be careful as components will be hot. Any leak
source must be repaired.
7. If there is no obvious leak source, check the coolant level
in the reserve tank. If there is none, or if it is too low,
slowly add coolant.
8. If the reserve tank needs coolant, you will probably also
need to add coolant to the radiator. Do not loosen or
remove the radiator cap until the engine has cooled down.9. Start the engine, and slowly add coolant, up to the bottom
of the filler neck. Use plain water if you have to (and
replace it with the right coolant as soon as possible).
10. Replace the radiator cap and tighten it fully. Check the
temperature indicator. You can drive when the indicator
returns to the normal zone.
11. Have your vehicle checked by your authorized Mitsubishi
Motors dealer or a repair facility of your choice.

Removing the radiator cap could scald you with
escaping hot water or steam. When checking the
radiator level, cover the cap with a cloth before try-
ing to remove it. Turn it slowly counterclockwise,
without pressing down, to the first notch. The pres-
sure in the system will then be let out. When the
pressure is COMPLETELY LET OUT, press down
and keep turning the cap counterclockwise until it
will come off.

7Engine coolant
N00937800281
To check the coolant level The coolant reserve system provides a quick visual method for
determining the coolant level. When the engine is cold, the
level of the coolant in the reserve tank should be between the
“F” (FULL) and “L” (LOW) marks. The radiator normally
remains completely full so there is no need to remove the radi-
ator cap except for checking the coolant freeze point or replac-
ing the antifreeze coolant.To add coolant Use Mitsubishi Genuine Coolant or an equivalent.
Mitsubishi Genuine Coolant provides excellent protection
against corrosion and rust formation on all metals, including
aluminum, and prevents blockages in the radiator, heater, cyl-
inder head, engine block, etc.
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.
CAUTION
!
Do not use alcohol or methanol antifreeze or any
engine coolants that contain them. Using the wrong
antifreeze can corrode aluminum parts.
When you need to add coolant to the reserve tank,
use at least a 50 % concentration of ethylene-glycol
antifreeze in water. Do not overfill. Use a higher con-
centration (not over 60 %) when the outside temper-
ature is -31 °F (-35 °C) or lower. When the engine is
working very hard (for example, during mountain
driving and/or when the outside temperature is
high), use a 50 % concentration. 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. Use
only high quality ethylene-glycol antifreeze coolant
that is made to prevent corrosion of all cooling sys-
tem metals.
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.

Radiator capThe radiator cap must be tight sealed to prevent losing coolant
which may result in engine damage. Only use a Genuine Mit-
subishi 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.

Keep the front of the radiator and condenser clean.

If the temperature of the engine coolant does not rise after
the engine is warmed-up, take your vehicle to an autho-
rized Mitsubishi Motors dealer or a repair facility of your
choice to have the thermostat checked, and replaced if
necessary.
Air cleaner filter
N00937900165
The air cleaner filter will get dirty and dusty from use and not
filter properly. Replace it with a new filter using the schedule
in the “WARRANTY AND MAINTENANCE MANUAL”. 2.4 liter modelsUnclamp and take out the air cleaner filter.
After replacing the air cleaner filter, put the cover back on in its
original position. 3.8 liter models1. Loosen the bolt of the resonator using a screwdriver.
2. Remove the resonator.

!
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.
