OIL FtLTER SELECTtONThis vehicle is equipped with a full-flow, throw-away oil
,~
filter.The same type of replacement filter is recommended as a
replacement filter for this vehicle. It is possible, particularilyin cold weather, that this vehicle may develop high oil
pressure for a short duration. You should be sure that any
replacement filter used on this vehicle is a high-quality filterand is capable of withstanding a pressure of 256 psi
(manufacturer’s specifications) to avoid filter and engine
damage. The following is a high-quality filter and is stronglyrecommended for use on this vehicle
: Mitsubishi Engine
-Oil Filter Part No. MD031805 or MD084693.
Any replacement oil filter should be installed in accordancewith the oil filter manufacturer’s installation instructions.
(1) Remove the engine oil filler cap.
(2) Remove the engine oil drain plug, and drain out the
engine oil.
(3) Remove the engine oil filter by using the oil filter
wrench.(4) Clean the oil filter mounting surface of the oil filter
bracket.(5) Coat engine oil to the O-ring of new oil filter.
(6) Turn the oil filter by hand to install to the block.
NOTEThe oil filter tightening torque is
11-13 Nm (8-10
ftlbs.).A(7) Supply engine oil.
.(8) Start and run engine and check for engine oil leaks.
(9) After stopping engine, check oil level and replenish as
necessary.9. MANUAL TRANSAXLE (Inspect oil level)
NOOSBCEbInspect each component for evidence of leakage, and
check the oil level by remaining the filler plug. If the oil is
contaminated, it is necessary to replace it with new oil.
1. With the vehicle parked at a level place, remove the
filler plug and check to be sure that the oil level is up tothe lower edge of the filler plug hole.
2. Check to be sure that the transmission oil is not
noticeably dirty, and that it has a suitable viscosity.

L-4GoodOOA0051C9FW1014K512(9) Supply 4 liters (8.5 pints) of specified ATF into case
through dipstick hole. [Total quantity of ATF required is
6.1 liters (12.9 pints).
Actually however, approx. 4.5 liters (9.5 pints) of fluid
can be replaced because rest of fluid remains in torque
converter.]Specified fluid: MOPAR ATF PLUS (Automatic
Transmission Fluid Type 7176) or
Dia ATF SP or Equivalent
(10)Start engine and allow to idle for at least two minutes.
Then, with parking brake on, move selector lever
momentarily to each position, ending in “N” Neutral
position.
(1 l)Add sufficient ATF to bring fluid level to lower mark.
Recheck fluid level after transaxle is at normal operating
temperature.
Fluid level should be between upper and lower marks of“HOT” range. Insert dipstick fully to prevent dirt from
entering transaxle.
11 .ENGINE COOLANT (Change)NOOSBEAcCheck the cooling system parts, such as radiator, heater,
and oil cooler hoses, thermostat and connections for
leakage and damage.
CHANGE COOLANT
1. Remove the radiator cap.
2. Loosen the drain plug to drain the coolant.
3. Drain the coolant from the reserve tank.
4. After draining the coolant, tighten the drain plug
securely.
5.Supply the coolant into the radiator until it is filled up to
its filler neck.
6. Supply the coolant into the reserve tank.
7. After warming the engine until the thermostat opens,
remove the radiator cap and check the coolant level.
8.Supply the coolant into the radiator until it is filled up to
its filler neck, and install the
.radiator, cap securely.
9.Fill the reserve tank with coolant up to the “FULL” line.12DISC BRAKE PADS (Inspect for wear)
NOOSBFA~Check for fluid contamination and wear. Replace complete
set of pads if defective.
Caution
The pads for the right and left wheels should be
replaced at the same time. Never “split” or intermix
brake pad sets.
All four pads must be replace as a complete set.

Symptom
NOTE
1 Probable cause1 Remedy
In addition to a malfunction of the differential carrier components, abnormal noise can also be caused by the universal
joint of the propeller shaft, the axle shafts, the wheel bearings, etc. Before disassembling any parts, take all
possibilities into consideration and confirm the source of the noise.

Noise from the engine, muffler vibration, transaxle, propeller shaft, wheel bearings, tires, body, etc., is easily mistaken
as being caused by malfunctions in the differential carrier components. Be extremely careful and attentive whenperforming the driving test, etc.
Test methods to confirm the source of the abnormal noise include:coasting acceleration, constant speed driving,
raising the rear wheels on a jack, etc. Use the method most appropriate to the circumstances.

BRAKES - Service Adiustment Procedures5-45I
\\14A0416
2314A04.54
BLEEDINGN65FYAN
When the master cylinder is empty of brake fluid, bleed air
from the master cylinder by proceeding with procedures (1)
thru (6). (Because this master cylinder is not equipped with a
check valve.)
When brake fluid remains in the master cylinder, proceed with
step (6).
(1) -Disconnect the brake tube from the master cylinder.
(2) Two persons should conduct the air bleeding, one person
slowly depressing the brake pedal and holding the pedal
depressed.(3) In this condition, the other person should use a finger to
close the outlet part of the master cylinder, and then the
first person should release the brake pedal.
(4) Steps (2) and (3) should be repeated three or four times,
and then the master cylinder should be filled with brake
fluid to the specified level.
NOTE
The air is completely bled from the master cylinder by steps
(1) to (4).
(5) Connect the brake tube to the master cylinder.
(6) Start the engine; then, in the sequence shown in the
illustration, bleed the air from each wheel cylinder.
Specified brake fluid: MOPAR Brake Fluid/
Conforming to DOT3
Caution
1.Use the specified brake fluid. Avoid using a mixture
of the specified brake fluid and other fluid.2. If brake fluid is exposed to the air, it will absorb
moisture; as water is absorbed from the atmos-phere, the boiling point of the brake fluid will
decrease and the braking performance will be
seriously impaired. For this reason, use a hermeti-
cally sealed 1 lit.
(1.06 qt.) or 0.5 lit. (0.52 qt.) brake
fluid container.3. Firmly close the cap of the brake fluid container
after use.
4. For vehicles with the anti-lock braking system, besure to install a filter to the master cylinder
reservoir tank when supplying brake fluid.
ORDINARY AIR-BLEEDING PROCEDURES(1) Depress the brake pedal several times until resistance is
felt; then, with the pedal depressed, loosen the bleeder
screw
l/3 to l/2 turn and then tighten it before the fluid
pressure is all gone.
(2) Release the brake pedal. Repeat this procedure until there
are no more air bubbles in the brake fluid.

COOLING - Troubleshooting7A7
OPERATION
1. When the output of the air conditioner*--control unit is “LO” (OV)(when the
compressor magnet clutch isdeenergized)
l When the ignition switch is at “ON” , and if
engine coolant temperature rises to
85°C
(185”F), the thermosensor contacts close,
causing current to flow through the radiator
fan motor relay (coil), thermosensor and
ground, causing the radiator fan motor relay
contacts to close.
l Current flows through the radiator fan motor
relay contacts, radiator fan motor and ground,causing the radiator fan motor to rotate.
2. When the output of the air conditioner
control unit is “HI” (approx. 12V)(when the
compressor magnet clutch is
energized)l If the therm0 sensor is “ON” when the
engine coolant temperature exceeds
85°C
(185°F). the condenser fan motor control relay
is also “ON”, thus the condenser fan as well
as the radiator fan start rotating at a high
speed.
TROUBLESHOOTING HINTS
1. Neither the radiator fan nor condenser fanrotate at
all.l Check sub fusible link
No.3.
2. Only the condenser fan does not operate.l Check dedicated fuse
No.5.
3. The radiator fan and condenser fan do notoperate
in the low speed mode, but operateotherwise.
(1)The A/C compressor magnet clutch does not
enter the “ON” state.
l Check whether the output of the air con-
ditioner control unit is available.
NOTEFor troubleshooting of the air conditioner
control unit, refer to GROUP 24.
(2)The A/C compressor magnet clutch enters
the “ON” state.
