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
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.

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.
WA R N I N G
!
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.

3. Unclamp and take out the air cleaner filter.
After replacing the air cleaner filter, install the resonator by fol-
lowing the removal steps in reverse. Fit the resonator with
careful reference to the alignment position (A), and securely
tighten the bolt.NOTE
Genuine Mitsubishi Motors Parts are recommended when
replacing the air cleaner filter.
Automatic transaxle fluid
(if so equipped)
N00938000512
The automatic transaxle should be maintained and serviced by
an authorized Mitsubishi Motors dealer or a repair facility of
your choice to obtain the best performance and longest life. It
is important that the transaxle fluid is kept at the correct level. To check the fluid level The fluid level should be checked when the engine temperature
gauge shows the engine is warmed up and the fluid in the tran-
saxle is heated to its normal working temperature. Driving with
the wrong fluid level will rapidly wear out the transaxle and
destroy the fluid.
CAUTION
!
Take care not to scratch the engine air flow sensor
when removing the air cleaner cover.

Procedure for checking the fluid level 1. With the brake pedal fully depressed and the engine
idling, select each gear momentarily, ending with the
selector lever in the “P” (PARK) position.
2. The fluid level should be at the HOT mark, but never
above the HOT mark when the engine is warmed up. Add
or drain fluid to get to the correct level.
3. Make certain that the dipstick cap is installed properly to
keep dirt and water out of the transaxle.
Fluid typeUse only “DIAMOND ATF SP III” transaxle fluid to ensure
optimum transaxle performance. Special additives Mitsubishi Motors Corporation does not recommend the addi-
tion of any fluid additives to the transaxle.
WA R N I N G
!
Transaxle fluid is extremely flammable and poison-
ous. Do not spill fluid when adding or draining.

The windshield and rear window washer (ECLIPSE only) fluid
reservoir is in the engine compartment.
Check the washer fluid level at regular intervals and add
washer fluid to reservoir if necessary. During cold weatherWhen freezing weather is anticipated, flush out the water in the
reservoir by operating the pump. Fill the reservoir with wind-
shield antifreeze (not radiator antifreeze), and operate the sys-
tem for a few seconds to flush out the residual water.

7 Brake fluid/Clutch fluid
(if so equipped)
N00938700229
The brake fluid and the clutch fluid share the reservoir tank.To check the fluid levelThe fluid level must be between the “MAX” and “MIN” marks
on the reservoir.
The fluid level is monitored by a float. When the brake fluid
level falls below the “MIN” mark, the brake fluid warning
lamp lights up.
The fluid level falls slightly with wear of the brake pads, but
this does not indicate any abnormality.
The fluid in the master cylinder should be checked when doing
other work under the engine hood. The brake system should
also be checked for leaks at the same time.If the fluid level falls markedly in a short length of time, it indi-
cates leaks from the brake system.
If this occurs, have the vehicle checked by an authorized
Mitsubishi Motors dealer or a repair facility of your choice.
Fluid typeUse the brake fluid conforming to DOT 3 or DOT 4. The reser-
voir cap must be tightly sealed to keep dirt and water out.
CAUTION
!
Do not let any petroleum-based fluid touch, mix
with, or get into the brake fluid. This will damage
the seals.
Be careful when handling brake fluid. It can damage
painted surfaces.
Use only the listed brake fluid. Different brands of
brake fluid have different additives, and these can
cause a chemical reaction. Do not mix brands of
brake fluid.
Keep the reservoir tank cap closed to keep the brake
fluid from evaporating.

always between the “MAX” and “MIN” level markings on the
fluid reservoir and refill the fluid, if necessary.Fluid type
Battery
N00939100318
The condition of the battery is very important for quick starting
and to keep the vehicle’s electrical system working properly.
Check the battery regularly.
If battery performance is suspect, have the battery and charging
system tested by an authorized Mitsubishi Motors dealer or a
repair facility of your choice.

Checking battery electrolyte level Use the following procedure to check the battery electrolyte
level.
1. Insert the tip of a screwdriver at the edge of the cap, pry
gently to remove the cap.2. The inside of the battery is divided into several compart-
ments.
Check the electrolyte level (A) in each cell.
The electrolyte level must be within the range (B) shown
in the illustration.
If it is necessary to add fluid, add only distilled water. Do
not overfill above the top of the range because a spill dur-
ing driving could cause damage.
WA R N I N G
!
If the battery goes flat, be sure to check the battery
electrolyte level before connecting booster cables.
After checking the battery electrolyte level, make
sure the caps are fitted securely.
If any of the caps has a loose fit, replace the battery.
