1-2 GENERALINFORMATIONAND MAINTENANCE
Chitton’s Total Car Care manual for the 199M10
Mitsubishi Mirage, Galant and Diamante is intended
to help you learn more about the inner workings of
your vehicle while saving you money on its upkeep
and operation.
The beginning of the book will likely be referred to
the most, since that is where you will find information
for maintenance and tune-up. The other sections deal
with the more complex systems of your vehicle. Oper-
ating systems from engine through brakes are cov-
ered to the extent that the average do-it-yourselfer be-
comes mechanically involved. This book will not
explain such things as rebuilding a differential for the
simple reason that the expertise required and the in-
vestment in special tools make this task uneconomi-
cal. It will, however, give you detailed instructions to
help you change your own brake pads and shoes, re-
place spark plugs, and perform many more jobs that
can save you money, give you personal satisfaction
and help you avoid expensive problems.
A secondary purpose of this book is a reference for
owners who want to understand their vehicle and/or
their mechanics better. In this case, no tools at all are
required.
Before removing any bolts, read through the entire
procedure. This will give you the overall view of what
tools and supplies will be required. There is nothing
more frustrating than having to walk to the bus stop
on Monday morning because you were short one bolt
on Sunday afternoon. So read ahead and plan ahead.
Each operation should be approached logically and
all procedures thoroughly understood before attempt-
ing any work.
All sections contain adjustments, maintenance, re-
moval and installation procedures, and in some cases,
repair or overhaul procedures. When repair is not con-
sidered practical, we tell you how to remove the part
and then how to install the new or rebuilt replacement.
In this way, you at least save labor costs. “Backyard”
repair of some components is just not practical.
Many procedures in this book require you to “label
and disconnect. . ” a group of lines, hoses or wires.
Don’t be lulled into thinking you can remember where
everything goes-you won’t. If you hook up vacuum
or fuel lines incorrectly, the vehicle may run poorly, if
at all. If you hook up electrical wiring incorrectly, you
may instantly learn a very expensive lesson.
You don’t need to know the official or engineering
name for each hose or line. A piece of masking tape
on the hose and a piece on its fitting will allow you to
assign your own label such as the letter A or a short name. As long as you remember your own code, the
lines can be reconnected by matching similar letters
or names. Do remember that tape will dissolve in
gasolrne or other fluids; if a component is to be
washed or cleaned, use another method of identifica-
tion. A permanent felt-tipped marker or a metal scribe
can be very handy for marking metal parts. Remove
any tape or paper labels after assembly.
It’s necessary to mention the difference between
maintenance and repair Maintenance includes rou-
tine inspections, adjustments, and replacement of
parts which show signs of normal wear Maintenance
compensates for wear or deterioration. Repair implies
that something has broken or is not working. A need
for repair is often caused by lack of maintenance. Ex-
ample, draining and refilling the automatic transaxle
fluid is maintenance recommended by the manufac-
turer at specific mileage intervals. Failure to do this
can shorten the life of the transmission/transaxle, re-
quiring very expensive repairs. While no maintenance
program can prevent items from breaking or wearing
out, a general rule can be stated: MAINTENANCE IS
CHEAPER THAN REPAIR.
Two basic mechanrc’s rules should be mentioned
here. First, whenever the left side of the vehicle or en-
gine is referred to, it is meant to specify the drivers
side. Conversely, the right side of the vehicle means
the passengers side. Second, screws and bolts are
removed by turning counterclockwise, and tightened
by turning clockwrse unless specifically noted.
Safety is always the most important rule. Con-
stantly be aware of the dangers involved in working
on an automobile and take the proper precautions.
See the informatron in this section regarding SER-
VICING YOUR VEHICLE SAFELY and the SAFETY
NOTICE on the acknowledgment page.
Pay attention to the instructions provided. There
are 3 common mistakes in mechanical work:
1. Incorrect order of assembly, disassembly or
adjustment. When taking something apart or putting
it together, performing steps in the wrong order usu-
ally just costs you extra time; however, it CAN break
something. Read the entire procedure before begin-
ning disassembly. Perform everything in the order in
which the instructions say you should, even if you
can’t immedrately see a reason for it. When you’re
taking apart something that is very intricate, you
might want to draw a picture of how it looks when as-
sembled at one point in order to make sure you get everything back in its proper position. We will supply
exploded views whenever possible. When making
adjustments, perform them in the proper order. One
adjustment possibly will affect another.
2. Overtorquing (or undertorquing). While it is
more common for overtorquing to cause damage,
undertorquing may allow a fastener to vibrate loose
causing serious damage. Especially when dealing
with aluminum parts, pay attention to torque specifi-
cations and utilize a torque wrench in assembly. If a
torque figure is not available, remember that if you
are using the right tool to perform the job, you will
probably not have to strain yourself to get a fastener
tight enough. The pitch of most threads is so slight
that the tension you put on the wrench will be multi-
plied many times in actual force on what you are
tightening. A good example of how critical torque is
can be seen in the case of spark plug installation, es-
pecially where you are putting the plug into an alu-
minum cylinder head. Too little torque can fail to
crush the gasket, causing leakage of combustion
gases and consequent overheating of the plug and
engine parts. Too much torque can damage the
threads or distort the plug, changing the spark gap.
There are many commercial products available for
ensuring that fasteners won’t come loose, even if they
are not torqued just right (a very common brand is
Loctite? If you’re worried
about getting something
together tight enough to hold, but loose enough to
avoid mechanical damage during assembly, one of
these products might offer substantial insurance. Be-
fore choosing a threadlocking compound, read the
label on the package and make sure the product is
compatible with the materials, fluids, etc. involved.
3. Crossthreading. This occurs when a part such
as a bolt is screwed into a nut or casting at the wrong
angle and forced. Crossthreading is more likely to
occur if access is difficult. It helps to clean and lubri-
cate fasteners, then to start threading the bolt, spark
plug, etc. with your fingers If you encounter resis-
tance, unscrew the part and start over again at a dif-
ferent angle until it can be inserted and turned several
times without much effort. Keep in mind that many
parts, especially spark plugs, have tapered threads,
so that gentle turning will automatically bring the part
you’re threading to the proper angle. Don’t put a
wrench on the part until its been tightened a couple
of turns by hand. If you suddenly encounter resis-
tance, and the part has not seated fully, don’t force it.
Pull it back out to make sure it’s clean and threading
properly.
Be sure to take your time and be patient, and al-
ways plan ahead. Allow yourself ample time to per-
form repairs and maintenance You may find main-
taining your car a satisfying and enjoyable
experience.
b See Figures 1 thru 15
Naturally, without the proper tools and equipment
it is impossible to properly service your vehicle. It
would also be virtually impossible
to catalog every
tool that you would need to perform all of the opera-
tions in this book. Of course, It would be unwise for
the amateur to rush out and buy an expensive set of
tools on the theory that he/she may need one or more
of them at some time, The best approach is to proceed slowly, gathering savings will
be far outweighed by frustration and

The Powertrain Control Module (PCM) is given
responsibrlity for the operation of the emission con-
trol devices, cooling fans, ignition and advance and
in some cases, automatic transaxle functions. Be-
cause the PCM oversees both the ignition timing and
the fuel injection operation, a precise air/fuel ratio
will be maintained under all operating conditions,
The PCM is a microprocessor, or small computer,
which receives electrical inputs from several sensors,
switches and relays on and around the engine.
Based on combinations of these inputs, the PCM
controls outputs to various devices concerned with
engine operation and emissions. The control module
relies on the signals to form a correct picture of cur-
rent vehicle operation. If any of the input signals is
incorrect, the PCM reacts to whatever picture is
painted for it. For example, if the coolant temperature
sensor is inaccurate and reads too low, the PCM may
see a picture of the engine never warming up. Conse-
quently, the engine settings will be maintained as if
the engine were cold. Because so many inputs can
affect one output, correct diagnostic procedures are
essential on these systems,
One part of the PCM is devoted to monitoring
both input and output functions within the system.
This ability forms the core of the self-diagnostic sys-
tem. If a problem is detected within a circuit, the con-
trol module will recognize the fault, assign it a Diag-
nostic Trouble Code (DTC), and store the code in
memory. The stored code(s) may be retrieved during
diagnosis. While the OBD-II system is capable of recognizing
many internal faults, certain faults WIII not be recog-
nized. Because the control module sees only electri-
cal signals, it cannot sense or react to mechanical or
vacuum faults affecting engine operation. Some of
these faults may affect another component which will
set a code. For example, the PCM monitors the out-
put signal to the fuel injectors, but cannot detect a
partially clogged injector. As long as the output dri-
ver responds correctly, the computer will read the
system as functioning correctly. However, the im-
proper flow of fuel may result in a lean mixture. This
would, in turn, be detected by the oxygen sensor and
noticed as a constantly lean signal by the PCM. Once
the signal falls outside the pre-programmed limits,
the control module would notice the fault and set a
trouble code.
Additionally, the OBD-II system employs adaptive
fuel logic. This process is used to compensate for
normal wear and variability within the fuel system.
Once the engine enters steady-state operation, the
control module watches the oxygen sensor signal for
a bias or tendency to run slightly rich or lean. If such
a bias is detected, the adaptive logic corrects the fuel
delivery to bring the air/fuel mixture towards a cen-
tered or 14.7:1 ratio. This compensating shift is
stored In a non-volatile memory which is retained by
battery power even with the ignition switched
OFF. The correction factor is then available the next time
the vehicle is operated.

Reading the control module memory is on of the
first steps in OBD II system diagnostics. This step
should be initially performed to determine the general
nature of the fault. Subsequent readings will deter-
mine if the fault has been cleared.

The automatic transaxle allows engine torque and
power to be transmitted to the front wheels within a
narrow range of engine operating speeds. It will allow
the engine to turn fast enough to produce plenty of
power and torque at very low speeds, while keeping it
at a sensible rpm at high vehicle speeds (and it does
this job without driver assistance). The transaxle uses
a light fluid as the medium for the transmission of
power. This fluid also works in ths operation of vari-
ous hydraulic control circuits and as a lubricant. Be-
cause the transaxle fluid performs all of these func-
tions, trouble within the unit can easily travel from one
part to another For this reason, and because of the
complexity and unusual operating principles of the
transaxle, a very sound understanding of the basic
principles of operation will simplify troubleshooting

REMOVAL &INSTALLATION
# See Figures 1, 2, 3, and 4
1. Park the vehicle on a level surface.
2. Remove the jack, tire iron and, if necessary,
the spare tire from their storage compartments.
3. Check the owners manual, or refer to Section
1 of this manual for the jacking points on your vehi-
cle. Then, place the jack in the proper position,
4. If equipped with lug nut trim caps, remove
them by either unscrewing or pulling them off the lug
nuts, as appropriate. Consult the owners manual, if
necessary.
5. If equipped with a wheel cover or hub cap,
insert the tapered end of the tire iron in the groove
and pry off the cover.
6. Apply the parking brake and block the diago-
nally opposite wheel with a wheel chock or two.
*Wheel chocks may be purchased at your
local auto parts store, or a block of wood cut
into wedges may be used. If possible, keep
one or two of the chocks in your tire storage
compartment, in case any of the tires has to
be removed on the side of the road. 7. If equipped with an automatic
transmission/transaxle, place the selector lever in P
or Park; with a manual transmission/transaxle, place
the shifter in Reverse.
8. With the tires still on the ground, use the tire
iron/wrench to break the lug nuts loose.
*If a nut is stuck, never use heat to loosen it
or damage to the wheel and bearings may
occur. If the nuts are seized, one or two
heavy hammer blows directly on the end of
the bolt usually loosens the rust. Be careful,
as continued pounding will likely damage the
brake drum or rotor.
9. Using the jack, raise the vehicle until the tire
is clear of the ground. Support the vehicle safely us-
ing jackstands.
10. Remove the lug nuts, then remove the tire
and wheel assembly.
To install:
11. Make sure the wheel and hub mating sur-
faces, as well as the wheel lug studs, are clean and
free of all foreign material. Always remove rust from
the wheel mounting surface and the brake rotor or
drum. Failure to do so may cause the lug nuts to
loosen in service.
12. Install the tire and wheel assembly and hand-
tighten the lug nuts. 13. Using the tire wrench, tighten all the lug nuts,
in a crisscross pattern, until they are snug.
14. Raise the vehicle and withdraw the jackstand,
then lower the vehicle.
15. Using a torque wrench, tighten the lug nuts in
a crisscross pattern to 65-80 ft. lbs. ( 90-l 10 Nm).
Check your owners manual or refer to Section 1 of
this manual for the proper tightening sequence.
Do not overtighten the lug nuts, as this may
cause the wheel studs to stretch or the brake
disc (rotor) to warp.
16. If so equipped, install the wheel cover or hub
cap. Make sure the valve stem protrudes through the
proper opening before tapping the wheel cover into
position.
17. If equipped, install the lug nut trim caps by
pushing them or screwing them on, as applicable.
18. Remove the jack from under the vehicle, and
place the jack and tire iron/wrench in their storage
compartments. Remove the wheel chock(s).
19. If you have removed a flat or damaged tire,
place it in the storage compartment of the vehicle and
take it to your local repair station to have it fixed or
replaced as soon as possible.
Inspect the tires for lacerations, puncture marks,
nails and other sharp objects. Repair or replace as
necessary. Also check the tires for treadwear and air
pressure as outlined in Section 1 of this manual.
Check the wheel assemblies for dents, cracks, rust
and metal fatigue. Repair or replace as necessary.
