10. ENGINE OIL (CHANGE)

M1001002600401

1. Start the engine and allow it to warm up until the

temperature of the coolant reaches 80

°C (176°F) to 90°C

(194

°F).

WARNING

Use care as oil could be hot.

2. Remove the engine oil filler cap.
3. Remove the drain plug to drain oil.
4. Install a new drain plug gasket so that it faces in the

direction shown in the illustration, and then tighten the drain
plug to the specified torque.

Tightening torque: 39 N

⋅m (29 ft-lb)

5. Refill the specified quantity of oil.

Specified Engine Oil: Engine oils displaying ILSAC

certification symbol or conforming to the API clas-
sification SL, SL/CF

Total quantity: 4.3 dm

(4.5 quarts) [add 0.3 dm

(0.32

quart) if replacing the oil filter

6. Install the engine oil filler cap.
7. Start the engine and run it at idle for a few minutes.

11. ENGINE OIL FILTER (REPLACE)

M1001002700389

The quality of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient service.
Genuine oil filters require that the filter is capable of withstand-
ing a pressure of 1,765 kPa (256 psi) are high quality filters and
are recommended as follows:

Mitsubishi Oil Filter Part Number: MD352626 or equiv-
alent

ENGINE OIL FILTER SELECTION
This vehicle is equipped with a full-flow, throw-away oil filter.
The same type of filter is recommended as a replacement filter
for this vehicle. It is possible, particularly in cold weather, that
this vehicle may develop high oil pressure for a short duration.
Make sure that any replacement filter used on this vehicle is a
high-quality filter. The filter can withstand a pressure of 1,765
kPa (256 psi) [manufacturer's specifications] to avoid the filter
and engine damage. The following is a high-quality filter and is
strongly recommended for use on this vehicle: Mitsubishi
Engine Oil Filter Part number MD136790.
Any replacement oil filter should be installed in accordance with
the oil filter manufacturer's installation instructions.
1. Remove the under cover.
2. Drain the engine oil by removing the oil drain plug.
3. Use an oil filter wrench to remove the engine oil filter.
4. Clean the contacting surface of the filter bracket.
5. Lubricate the O-ring of the new oil filter with a small amount

of new engine oil.

12. TRANSMISSION FLUID (CHECK THE FLUID
LEVEL)

M1001002900372

1. Drive the vehicle until the transmission fluid temperature

rises to the normal temperature [70

− 80°C (158 − 176°F)].

NOTE: The transmission fluid temperature is measured with
scan tool (MUT-III sub assembly).
NOTE: If it takes some amount of time until the transmission
fluid reaches its normal operating temperature [70

−

(158

−

176

F)], check the transmission fluid level by refer-

ring to the left diagram.

2. Park the vehicle on a level surface.
3. Move the selector lever through all positions to fill the torque

converter and the hydraulic circuits with fluid, and then move
the selector lever to the "N" position.

4. After wiping off any dirt around the dipstick, remove the

dipstick and check the condition of the fluid.
NOTE: If the fluid smells as if it is burnt, it means that the
fluid has been contaminated by fine particles from the bush-
ings and friction materials. A transmission overhaul and
flashing the cooler line flushing may be necessary.

5. Check that the transmission fluid level is at the "HOT" mark

on the dipstick. If the transmission fluid level is lower than
this, pour in more DIAMOND ATF SP-III until the level
reaches the "HOT" mark.
NOTE: If the transmission fluid level is too low, the oil pump
will draw in air along with the transmission fluid, which will
cause bubbles to form. If the transmission fluid level is too
high, rotating components inside the transmission will churn
the transmission fluid and air into a foamy liquid. Both condi-
tions (level too low or too high) will cause the hydraulic
pressure to drop, which will result in late shifting and slipping
of the clutches and brakes.
In either case, air bubbles can interfere with normal valve,
clutch, and brake operation. Foaming can cause transmis-
sion fluid to escape from the transmission vent, in which
case it may be mistaken for a leak.

6. Securely insert the dipstick.

NOTE: The fluid and filter should always be replaced when:

•

When troubleshooting the transmission

•

When overhauling the transmission

•

When the oil is noticeably dirty or burnt (vehicle was
driven under severe conditions)

Further more, the oil filters are special filters which are only
to be used for the automatic transmission.

13. TRANSFER OIL (CHECK OIL LEVEL) <V4A51>

M1001006300071

TRANSFER OIL CHECK
1. Remove the filler plug.
2. Check that the oil level is up to the lower edge of the filler

plug hole.

3. Check that the oil is not noticeably dirty, and that it has a

suitable viscosity.

4. Tighten the filler plug to the specified torque.

Tightening torque: 29

− 34 N⋅m (21 − 25 ft-lb)

14. ENGINE COOLANT (CHANGE)

M1001003100391

Required Special Tools:

• MB991871: LLC changer

Check the cooling system parts such as the radiator, heater
and oil cooler hoses, thermostat and the connections for leak-
age and damage.

CHANGING COOLANT
1. Set the temperature control knob to the "HOT" position.

CAUTION

When removing the radiator cap, use care to avoid contact
with hot coolant or steam. Place a shop towel over the cap
and turn the cap counterclockwise a little to let the pres-
sure escape through the vinyl tube. After relieving the
steam pressure, remove the cap by slowly turning it coun-
terclockwise.
2. Remove the radiator cap, radiator drain plug and cylinder

block drain plug to drain the coolant.

3. Remove the reserve tank and drain the coolant.
4. After completely draining the coolant, reinstall the drain

plugs and flush the engine and radiator using a radiator
cleaning fluid.

5. After the flushing is completed, completely drain the

cleaning fluid.
