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.

LUBRICATION AND MAINTENANCE - Maintenance ServiceO:lllO.AUTOMATIC TRANSAXLE (Inspect fluid
I~~+v~!1. Drive until the fluid temperature reaches the usual
temperature
[70-80°C (160- 18O”F)l.2. Place vehicle on level floor.
3.Move selector lever sequentially to every position to fill
torque converter and hydraulic
circuitwith fluid, then
place lever in“N” Neutral position. This operation is
necessary to be sure that fluid level check is accurate.
4.Before removing dipstick, wipe all dirt from area arounddipstick. Then take out the dipstick and check the
condition of the fluid.
The transaxle should be overhauled under the following
conditions.l If there is a “burning” odor.
l If the fluid color has become noticeably blacker.
l If there is a noticeably great amount of metal
particles in the fluid.
5.Check to see if fluid level is in “HOT” range on dipstick.If fluid level is low, add ATF until level reaches “HOT”
range.Low fluid level can cause a variety of conditions
because it allows pump to take in air along with fluid. Airtrapped in hydraulic circuit forms bubbles which make
fluid spongy. Therefore, pressures will be erratic.
Improper filling can also raise fluid level too high. Whentransaxle has too much fluid, gears churn up foam and
cause same conditions which occur with low fluid level,resulting in accelerated deterioration of ATF.
transmission fluid.
In either case, air bubbles can cause overheating, fluid
oxidation, which can interfere with normal valve, clutch,and servo operation. Foaming can also result in fluid
escaping from transaxle vent where it may be mistakenfor a leak.
6. Be sure to examine fluid on dipstick closely.lO.AUTOMATIC TRANSAXLE (Change fluid)
Drain the fluid and check whether there is any evidence of
contamination.
Replenish with new fluid after the cause of any contamina-tion has been corrected.
(1) Remove drain plugs to let fluid drain.
(2) Remove the oil pan.
(3) Check the oil filter for clogging and damage and replaceif necessary.
(4) Clean the inside of oil pan and 5 magnets.
(5) Attach the five magnets to the concave part of the oil
(6)
Elan both gasket surfaces of transaxle case and oil
pan.(7) Install oil pan with new gasket and tighten oil pan bolts

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.

13.BRAKE HOSES (Check for deteriorati.on or
leaks)NwBBnAs
Inspection of brake hoses and tubing should be included inall brake service operations.
The hoses should be checked for:
1. Correct length, severe surface cracking, pulling, scuf-
fing or worn spots. (If the fabric casing of the hoses is
exposed by cracks of abrasion in the rubber hose cover,
the hoses should be replaced. Eventual deterioration ofhose may occur with possible bursting failure.)
2. Faulty installation, casing twisting or interference with
wheel, tire of chassis.
14.BALL JOINT AND STEERING LINKAGE SEALS
(Inspect for grease leaks and damage)
NWSBJAb1. These components, which are permanently lubricated
at the factory, do not require periodic lubrication.
Damaged seals and boots should be replaced to
prevent leakage or contamination of the grease.
2. Inspect the dust cover and boots for proper sealing,
leakage and damage. Replace them if defective.
15.DRIVE SHAFT BOOTS (Inspect for grease leaksand damage)
NWSBJAc1. These components, which are permanently lubricated
at the factory, do not require periodic lubrication.
Damaged boots should be replaced to prevent leakage
or contamination of the grease.

damage. Replace it if defective.
16.REAR AXLE (CONVENTIONAL DIFFERENTIAL)(Inspect oil level)-AWD
NWSBFCa
Remove the filler plug and inspect the oil level at bottom offiller hole. If the oil level is slightly below the filler hole, it is
in satisfactory condition.
16.REAR AXLE (LIMITED-SLIP DIFFERENTIAL)
(Oil change)-AWD
N66SBFCcBefore changing the rear axle oil, check to make sure that
there is no oil leakage from the rear axle housing.
Remove the drain plug and drain out of the oil.
Put the oil plug back in place, and then pour new oil in
through the filler hole.
17.EXHAUST SYSTEM (CONNECTION PORTION
OF MUFFLER, PIPING AND CONVERTER HEATSHIELDS) (Check and service as
