8. DRIVE BELT (FOR GENERATOR AND WATER
PUMP, POWER STEERING PUMP) (CHECK
CONDITION)

M1001002500459

DRIVE BELT TENSION CHECK

Check the drive belt tension by the following procedure.

<When using scan tool MB991958>

Required Special Tools:

• MB991668: Belt Tension Meter Set

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)

• MB991911: MUT-III Main Harness B

CAUTION

To prevent damage to scan tool MB991824, always turn the
ignition switch to the "LOCK" (OFF) position before con-
necting or disconnecting scan tool MB991824.
1. Connect special tool MB991668 to scan tool MB991824.
2. Connect scan tool MB991910 to scan tool MB991824.
3. Connect scan tool MB991910 to the data link connector.
4. Turn the ignition switch to the "ON" position and select "Belt

Tension" from the menu scan tool MB991824 screen.

CAUTION

• The temperature of the surface of the belt should be as

close as possible to underhood temperature.

• Do not let any contaminants such as water or oil get

onto the microphone.

• If strong gusts of wind blow against the microphone or

if there are any loud sources of noise nearby, the val-
ues measured by the microphone may not correspond
to actual values.

• If the microphone is touching the belt while the mea-

surement is being made, the values measured by the
microphone may not correspond to actual values.

• Do not take the measurement while the vehicle's engine

is running.

5. Hold special tool MB991668 (microphone) to the middle of

the drive belt between the pulleys (at the place indicated by
the arrow), about 10

− 20 mm (0.4 − 0.8 inch) away from the

rear surface of the belt and so that it is perpendicular to the
belt (within an angle of

± 15 degree angle).

6. Gently tap the middle of the belt between the pulleys (the

place indicated by the arrow) with your finger as shown in
the illustration, and check that the vibration frequency of the
belt is within the standard value.

Standard value: 88

− 121 Hz

leaks.

3. Check the hanger rubber and brackets for damage.

10. ENGINE OIL (CHANGE)

M1001002600382

P.00-33

1. After warming up the engine, remove the oil filler cap.

WARNING

Use care. Oil could be hot.

2. Remove the drain plug to allow the engine oil to drain.
3. Replace the drain plug gasket with a new one, and then

tighten the drain plug to the specified torque.
NOTE: Install the drain plug gasket so it faces in the direc-
tion shown in the illustration.

Tightening torque: 39

± 5 N⋅m (29 ± 3 ft-lb)

4. Pour new engine oil in through the oil filler tube.

Engine oil capacity: 4.3 dm

(4.5 quarts) [excluding oil

filter 0.3 dm

(0.32 quart), oil cooler 0.3 dm

(0.32

quart)]

5. Start the engine and run it at idle for a few minutes.
6. Stop the engine and check to ensure that the engine oil level

is within the level range indicated on the dip stick.

11. ENGINE OIL FILTER (REPLACE)

M1001002700367

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 MD352626.
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 contact 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

M1001002900350

Checking transmission fluid level

1. Drive the vehicle until the fluid temperature rises to the

normal temperature [70

− 80°C (158 − 176°F)].

If it takes some amount of time until the transmission fluid
reaches its normal operating temperature [70

− 80°C (158 −

176

°F)], check the transmission fluid level by referring to the

diagram at left.
NOTE: The transmission fluid temperature is measured with
scan tool MB991502.

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 from 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 fluid level is at the "HOT" mark on the

dipstick. If the fluid level is lower than this, pour in more
MITSUBISHI GENUINE ATF SP-III or equivalent until the
level reaches the "HOT" mark.
NOTE: If the fluid level is too low, the oil pump will draw in
air along with the fluid, which will cause bubbles to form.
This will in turn cause the hydraulic pressure to drop, which
will result in late shifting and slipping of the clutches and
brakes.
If the fluid level is too high, the gear makes bubbles in trans-
mission fluid. Same phenomena will occur when the trans-
mission fluid volume is little.
In either case, air bubbles can interfere with normal valve,
clutch, and brake operation. Foaming can cause 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 trouble shooting 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.

Change transmission fluid

If you have a fluid changer, replace the fluid by the following
procedure.
1. Disconnect the hose shown in the illustration which

connects the transmission and the oil cooler (inside the
radiator). Place a container under the hose to collect the
transmission fluid.

2. Start the engine and let the fluid drain out.

Running conditions: "N" range with engine idling

CAUTION

The engine should be stopped within one minute after it is
started. If the fluid has all drained out before then, the
engine should be stopped at that point.
3. Remove the drain plug from the bottom of the transmission

case to drain the fluid.

Discharge volume: Approximately 2.0 dm

(2.1 quarts)

4. Install the drain plug with a new gasket, and tighten it to the

specified torque.

Tightening torque: 32

± 2 N⋅m (24 ± 1 ft-lb)

5. Pour new transmission fluid in through the oil filler tube.

Adding volume: Approximately 6.0 dm

(6.3 quarts)
