the work in that section
is finished.
Maintenance and Servicing Procedures
(1) A diagram of the component parts is provided near the front of each section in
order to give the reader a better under-
standing of the installed condition of
component parts.
(2) The numbers provided within the diagram indicate the sequence for maintenance
and servicing procedures; the symbol
mindicates a non-reusable part; the tighten-
ing torque is provided where applicable. l Removal steps:
The part designation number corres-
ponds to the number in the illustration
to indicate removal steps.
l Disassembly steps: The part designation number corres-
ponds to the number in the illustration
to indicate disassembly steps.
l Installation steps: Specified in case installation is impossi-
ble in reverse order of removal steps.
Omitted if installation is possible in
reverse order of removal steps.
8 Reassembly steps: Specified in case reassembly is im-
possible in reverse order of disassem-
bly steps.
Omitted if reassembly is possible in reverse order of disassembly steps.

MATERIALS ADDED TO FUEL
unleaded gasoline having a octane rating of 87 or
91 RON (Research Octane Number) may be used. Indiscriminate use of fuel system cleaning agents
In this case, the performance and fuel consumption should be avoided. Many of these materials
in-
WIII suffer a little degradatron.tended for gum and varnish removal may contain
highly active
solvents or similar ingredients that can
be harmful to gasket and diaphragm materials used
in fuel system component parts.
Gasolines containing alcohol
Some gasolrnes sold at service stations contain
alcohol, although they may not be SC identified. Use
of fuels containing alcohol is not recommended
unless the nature of the blend can be
determrned
as being satisfactory.
Gasohol
- A mixture of 10% ethanol (grain alcohol)
and 90% unleaded gasoline may be used
In your
car. If
driveability problems are experienced as a
result of using gasohol, it IS recommended that the
car be operated on gasoline. Methanol
- Do not use gasolines containing
methanol (wood alcohol). Use of this type of
alcohol can result in vehicle performance deteriora-
tion and damage critical parts in the fuel system
components. Fuel system damage and performance
problems, resulting from the use of gasolines
containing methanol, may not be covered by the
new car warranty.
Gasolines containing MTBE (Methyl Tertiary Butyl
Ether)
Unleaded gasolrne containrng
15% or less MTBE
may be used in your car. (Fuel containing MTBE
over 15% vol. may cause reduced engine per-
formance and produce vapor lock or hard starting.) RECOMMENDED

ENGINE OIL FILTER SELECTION
This vehicle is equipped with a full-flow, throw-away oilfilter.
The same type of replacement filter is recommended as a replacement filter for this vehicle. It is possible, particularily
in 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 filter
and 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 strongly
recommended for use on this vehicle
: Mitsubishi Engine
Oil Filter Part No. MD1 35737 or MD1 36466.
Any replacement oil filter should be installed in accordance
with 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
(4)
GLr!he oil filter mounting surface of the oil filter
bracket.
OSPOO26 1 09A.0024(5) Coat engine oil to the O-ring of new oil filter.
(6) Screw in the oil filter with hand until it touches the sur-
face of the flange and then tighten it with the filter
wrench, etc.
l For MD135737:
One full turn or 14 Nm
(loft. Ibs.)0For MD136466:3/4 turn or 17 Nm (12 ft. Ibs.)
(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)
MOO66CE
Inspect 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.
I. With the vehicle parked at a level place, remove the filler plug and check to be sure that the oil level is up to
the 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.

4. CHECKING THE VEHICLE-SPEED SENSOR CIRCUIT
Combination meter
E-2
Description of operation
The vehicle-speed sensor is installed within the speedometer; it sends to the control unit pulsesignals that are proportional to the rotation speed
(i.e., the vehicle speed) of the transmission’s
output gear. This vehicle-speed sensor is the reed switch type
of sensor; it generates four pulse signals for eachrotation of the speedometer’s driven gear.

16. REMOVAL OF REAR SUSPENSION ASSEMBLY
(1) Supporting the rear suspension assembly with a trans-
mission jack, move it toward the rear (in the direction of
the fuel tank).
(2)
Graduallyibwer the transmission jack, avoiding contact
with the stabilizer bar and the propeller shaft.
Caution
1. Ensure that the propeller shaft does not bend
greatly.
2.Ensure that the liibro joint does not receive any
shock.
NOTE
The lowering of the rear suspension assembly from the
transmission jack requires three individuals due to the
amount of weight being handled (one on the differen-
tial, and one on either side of the lower arm).
(3) In order to protect the rear suspension assembly dust shield, support the lower arm ball joint with a wooden
block.
