72A0044Oil Identification Symbol
A standard symbol appears on the top of oil containers and hasthree district areas for identifying various aspects of the oil.
The top portion will indicate the quality of the oil. The center
portion will show the SAE viscosity grade, such as SAE
IOW-30. “Energy Conserving” shown in the lower portion,
indicates that the oil has fuel-saving capabilities.

concentration
ExampleThe safe operating temperature is
- 15°C (5°F) when the measured specific gravity is 1.058 at the coolant
temperature of
20°C (68°F).
Cautions1. If the concentration of the coolant is below 30%, the anti-corrosion property will be adversely
affected. In addition, if the concentration is above 60%, both the anti-freeze and engine cooling
properties will decrease, affecting the engine adversely. For these reasons, be sure to maintain theconcentration level within the specified range.
2. Do not use a mixture of different brands of anti-freeze.

LUBRICATION AND MAINTENANCE - Maintenance Service
MAINTENANCE SERVICE1. FUEL SYSTEM (Tank, Lines,
Connect%ms and
Fuel Filler Cap) (Check for
leaks)/2. FUEL
HOSE (Check for leaks or
damage)1 NSOSAGtib1. Check for damage or leakage in the fuet
lines and
connections and looseness of the fuel
fi!:ler cap.
2.Inspect the surface of fuel hoses for heat and mecha-
nical damage. Hard and brittle rubber, cracking, check-
ing, tears, cuts, abrasions and excessive swelling
indicate deterioration of the rubber.
3. If the fabric casing of the rubber hose is exposed by
cracks and abrasions in the fuel system, the hoses
should be changed.
3. AIR CLEANER ELEMENT (Replace)
NOOSAKBbThe air cleaner element will become dirty and loaded with
dust during use, and the filtering effect will be substantially
reduced. Replace it with a new one.
<1.8L Engine, 2.0L DOHC Engine (Non-Turbo)>
(1) Disconnect the air-flow sensor connector.
(2) Remove the air intake hose.
(3) Unclamp the air cleaner cover.
(4) Push the air intake hose backward, and remove the air
cleaner cover.
Caution
Care must be taken when removing the air cleaner
cover, because the air-flow sensor is ‘attached.
(5) Take out the air cleaner element.
<2.0L DOHC Engine (Turbo)>
(1) Disconnect the air-flow sensor connector.
(2) Disconnect the boost hose.
(3) Disconnect the solenoid valve with hoses.
(4) Disconnect the air intake hose.
(5) Remove the air cleaner retaining bolts.
(6) Remove the air cleaner assembly.
(7) Unclamp the air cleaner cover.
Caution
Care must be taken when removing the air cleaner
cover, because the air-flow sensor is attached.
(8) Take out the air cleaner element.

NOOSAOFa1. Spark plugs must spark properly to assure proper
~engine performance and reduce exhaust emission
level.Therefore, they should be replaced periodically with
new ones.
2. The new plugs should be checked for the proper gap.
Spark plug gap
1.0-1.1 mm (.039-.043 in.)

0.7-0.8 mm (.028-.031 in.)
3.Install the spark plug and tighten to 20-30 Nm (15-21
ft.lbs.).5. TIMING BELT (Replace)
NOOSBACaReplace the belt with a new one periodically to assure
proper engine performance.
For removal and installation procedures, refer to GROUP
g-Timing Belt.
6. DRIVE BELT (For Water
Pump and Alternator)
(Inspect for tension)
NOOSSBN(1) Place straight edge as shown in the illustration.
(2) Measure the deflection with a force of
100 N (22 Ibs.)rzapplied to belt mid-point between water pump pulley
-and alternator pulley. If the standard value is not
obtained, make adjustment.
Standard value:
<1.8L Engine>8.0-11.0 mm (.315-A33 in.)
<2.0L DOHC Engine>
9.0-11.5 mm (.354-.453 in.)
(3) Use a tension gauge to check the belt tension. If the
standard value is not obtained, make adjustment.
When tension gauge is used, the tension may be
measured between any two pulleys.
Standard value:
250-500 N (55-110 Ibs.)

01R03407. ENGINE OIL (Change)
NWSAAFAlways use lubricants which conform to the requirements
of the API classification “For Service SG” or “For Service
SGKD” .when available, and have the proper SAE grade
number for the expected temperature range.
Never use nondetergent or straight mineral oil.
(1) After warming up the engine, remove the oil filler cap.
(2) Remove the drain plug to allow the engine oil to drain.
(3) Replace the drain plug gasket with a new one and
tighten the drain plug.
(4) Supply new engine oil through the oil filler.
Engine oil total capacity:
< 1.8L Engine>3.9 liters (4.1 qts.)
<2.0L DOHC-Non-Turbo>4.4 liters (4.8 qts.)
<2.0L DOHC-Turbo>4.7 liters (5.0 qts.1[including oil filter 0.4 liter
(l/2 qt.)]
(5) Start and run the engine a few minutes.
(6) Stop the engine and check the engine oil level.
8. ENGINE OIL FILTER (Change)
NOO!SABGaThe 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
withstanding a pressure of 256 psi
.are high quality filters
and are recommended as follows:
Oil Filter Part No.
Mitsubishi Genuine Parts: MD031805 or equivalent
NOTEFactory installed Mitsubishi Engine Oil Filter PartNo.MD084693 or MD031805.

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.

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.
