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.

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

* Timing-light.
The choice of a timing fight should be made
carefully. A light which works on the DC current
supplied by the vehicle’s battery is the best choice;
it should have a xenon tube for brightness. On any
vehicle with an electronic ignition system, a timing
light with an inductive pickup that clamps around
the No. 1 spark plug cable is preferred.
In addition to these basic tools, there are several
other tools and gauges you may find useful. These
include:
l Compression gauge. The screw-in type is
slower to use, but eliminates the possibility of a
fauliy reading due to escaping pressure.
l Manifold vacuum gauge. l 12V test light. l A combination volt/ohmmeter l induction Ammeter. This is used for determin-
ing whether or not there is current in a wire. These
are handy for use if a wire is broken somewhere in a
wiring harness.
As a final note, vou will orobablv find a torque
wrench necessary for all but the most basic work.
The beam type models are perfectly adequate, al-
though the newer click types (breakaway) are easier
to use. The click type torque wrenches tend to be
more expensive. Also keep in mind that all types of
torque wrenches should be periodically checked
and/or recalibrated. You will have to decide for your-
self which better fits your pocketbook, and purpose.
ilightly more sophisticated, they need not be outra-
feously expensive. There are several inexpensive
achldwell meters on the market that are every bit as
Toad for the average mechanic as a professional
nodel. Just be sure that it goes to a least 1200-1500
pm on the tach scale and that it works on 4,6 and 8-
:ylinder engines. The key to these purchases is to
nake them with an eye towards adaptability and wide
ange. A basic list of tune-up tools could include:
l Tach/dwell meter. l Spark plug wrench and gapping tool. Normally, the use of special factory tools is
avoided for repair procedures, since these are not
readily available for the do-it-yourself mechanic.
When it is possible to perform the job with more
commonly available tools, it will be pointed out, but
occasionally, a special tool was designed to perform
a specific function and should be used. Before sub-
stituting another tool, you should be convinced that
neither your safety nor the performance of the vehicle
will be compromised.
Special tools can usually be purchased from an
automotive parts store or from your dealer. In some
cases special tools may be available directly from the
tool manufacturer.
p See Figures 16, 17, 16, and 19
It is virtually impossible to anticipate all of the haz-
ards involved with automotive maintenance and ser-
vice, but care and common sense will prevent most
accidents.
The rules of safety for mechanics range from “don’t
smoke around gasoline,” to “use the proper tool(s) for
the job.” The trick to avoiding injuries is to develop
safe work habits and to take every possible precaution.
Do keep a fire extinguisher and first aid kit
l handy.
Do wear safety glasses or goggles when cut- l ting, drilling, grinding or prying, even if you have
20-20 vision. If you wear glasses for the sake of vi-
sion, wear safety goggles over your regular glasses.
l Do shield your eyes whenever you work around
the battery. Batteries contain sulfuric acid. In case of
contact with the eyes or skin, flush the area with water
or a mixture of water and baking soda, then seek im-
mediate medical attention.
l Do use safety stands (jackstands) for any un-
dervehicle service. Jacks are for raising vehicles;
jackstands are for making sure the vehicle stays
raised until you want it to come down. Whenever the
vehicle is raised, block the wheels remaining on the
ground and set the parking brake.
l Do use adequate ventilation when working
with any chemicals or hazardous materials, Like car-
bon monoxide, the asbestos dust resulting from
some brake lining wear can be hazardous in suffi-
cient quantities.
l Do disconnect the negative battery cable when
working on the electrical system. The secondary ig- nition system contains EXTREMELY HIGH VOLT-
AGE. In some cases it can even exceed 50,000 volts.
l Do follow manufacturer’s directions whenever
working with potentially hazardous materials. Most
chemicals and fluids are poisonous if taken inter-
nally.
l Do properly maintain your tools. Loose ham-
merheads, mushroomed punches and chisels, frayed
or poorly grounded electrical cords, excessively
worn screwdrivers, spread wrenches (open end),
cracked sockets, slipping ratchets, or faulty droplight
sockets can cause accidents.
* Likewise, keep your tools clean; a greasy
wrench can slip off a bolt head, ruining the bolt and
often harming your knuckles in the process.
l Do use the proper size and type of tool for the
job at hand. Do select a wrench or socket that fits the
nut or bolt. The wrench or socket should sit straight,
not cocked.

1-26 GENERALINFORMATIONAND MAINTENANCE
TDC of the compression stroke. If this happens, the
piston WIII be at the beginning of the power stroke
just as the compressed and ignited air/fuel mixture
forces the piston down and turns the crankshaft. Be-
cause it takes a fraction of a second for the spark
plug to ignite the mixture in the cylinder, the spark
plug must fire a little before the piston reaches TDC.
Otherwise, the mixture will not be completely ignited
as the piston passes TDC and the full power of the
explosion will not be used by the engine.
The timing measurement is given in degrees of
crankshaft rotation before the piston reaches TDC
(BTDC). If the setting for the ignition timing is 10”
BTDC, each spark plug must fire 10 degrees before
each piston reaches TDC. This only holds true, how-
ever, when the engine is at idle speed. The combus-
tion process must be complete by 23”ATDC to main-
tain proper engine performance, fuel mileage, and
low emissions.
As the engine speed increases, the pistons go
faster. The spark plugs have to ignite the fuel even
sooner if it IS to be completely ignited when the pis-
ton reaches TDC. If the ignition is set too far ad-
vanced (BTDC), the ignition and expansion of the fuel
in the cylinder wtll occur too soon and tend to force
the piston down while it is still traveling up. Thus
causes pre ignition or “knockmg and pinging”. If the
ignition spark is set too far retarded, or after TDC
(ATDC), the piston will have already started on its
way down when the fuel is ignited. The piston will be
forced down for only a portion of its travel, resulting
in poor engine performance and lack of power.
Timing marks or scales can be found on the rim of
the crankshaft pulley and the timing cover. The marks
on the pulley correspond to the posrtion of the piston
in the No. 1 cylinder. A stroboscopic (dynamic) tim-
ing light is hooked onto the No. 1 cylinder spark plug
wrre. Every time the spark plug fires, the timing light
flashes. By aiming the light at the timing marks while
the engine is running, the exact position of the piston
within the cylinder can be easily read (the flash of
light makes the mark on the pulley appear to be
standing still). Proper timing is indicated when the
mark and scale are in specified alignment.
When checking timing with the engine run-
ning, take care not to get the timing light
wires tangled in the tan blades and/or drive
belts.

Used fluids such as engine oil, transaxle fluid, an-
tifreeze and brake fluid are hazardous wastes and
must be disposed of properly. Before draining any
fluids, consult with your local authorities; in many ar-
eas, waste oil, antifreeze, etc. is being accepted as a
part of recycling programs. A number of service sta-
tions and auto parts stores are also accepting waste
fluids for recycling.
Be sure of the recycling center’s policies before
draining any fluids, as many will not accept different
fluids that have been mixed together.
ENGINE OIL

WMitsubishi recommends that SAE 5W-30
viscosity engine oil should be used for all clia
mate conditions, however, SAE low-30 is ac
ceptable for vehicles operated in moderate-
to-hot climates. the SAE number, the lighter the oil; the lower the vis-
cosity, the easier it is to crank the engine in cold
weather but the less the oil will lubricate and protect
the engine in high temperatures. This number is
marked on every oil container.
Oil viscosity’s should be chosen from those oils
recommended for the lowest anticipated temperatures
during the oil change interval. Due to the need for an
oil that embodies both good lubrication at high tem-
peratures and easy cranking in cold weather, multi-
grade oils have been developed. Basically, a multi-
grade oil is thinner at low temperatures and thicker at
high temperatures. For example, a low-40 oil (the W
stands for winter) exhibits the characteristics of a 10
weight (SAE 10) oil when the car is first started and
the oil is cold. Its lighter weight allows it to travel to
the lubricating surfaces quicker and offer less resis-
tance to starter motor cranking than, say, a straight
30 weight (SAE 30) oil. But atier the ensine reaches
operating temperature, the low-40 oil begins acting
like straight 40 weight (SAE 40) oil, its heavier weight
providing greater lubrication with less chance of
foaming than a straight 30 weight oil. Synthetic oil is not for every car and every type of
driving, so you should consider your engine’s condi-
tion and your type of driving. Also, check your car’s
warranty conditions regarding the use of synthetic oils.
FUEL
All models equipped with a SOHC (Single Over-
head Camshaft) engine are designed to operate using
regular unleaded fuel with a minimum of 87 octane.
All models equipped with a DOHC (Dual Overhead
Camshaft) engine are designed to operate using reg-
ular unleaded fuel with a minimum of 91 octane. Mit-
subishi warns that using gasoline with a lower octane
rating can cause persistent and heavy knocking, and
may cause internal engine damage.
If your vehicle is having problems with rough idle
or hesitation when the enoine is cold, it mav be
caused by low volatility fuel. If this occurs, iry a dif-
ferent grade or brand of fuel.

Synthetic Oil
There are many excellent synthetic and fuel-effi-
cient oils currently available that can provide better
gas mileage, longer service life and, in some cases,
better engine protection. These benefits do not come
without a few hitches, however; the main one being
the price of synthetic oil, which is significantly more
expensive than conventional oil.

lubrication fittings on lube points on the steering

CAR WASHING
The car should be washed at regular intervals to
remove dirt, dust, insects, and tar and other possibly
damaging stains that can adhere to the paint and may
cause damage. Proper exterior maintenance also
helps in the resale value of the vehicle by maintaining
its like-new appearance.
Mt is particularly important ta frequentiy
wash the car in the wintertime to prevent cor-
rosion, when salt has been used on the roads.
There are many precautions and tips on washing,
including the following:
l When washing the car, do not expose it do di-
rect sunlight.
. Use lukewarm water to soften the dirt before
you wash with a sponge, and plenty of water, to avoid
scratching.
l A detergent can be used to facilitate the soften-
ing of dirt and oil. * A water-soluble grease solvent may be used in
cases of sticky dirt. However, use a washplace with a
drainage separator.
l Dry the car with a clean chamois and remem-
ber to clean the drain holes in the doors and rocker
panels.
l If equipped with a power radio antenna, it must
be dried after washing.
Never clean the bumpers with gasoline or
paint thinner, always use the same agent as
used on the painted surfaces of the vehicle.
l Tar spots can be removed with tar remover or
kerosene after the car has been washed.
l A stiff-bristle brush and lukewarm soapy water
can be used to clean the wiper blades. Frequent
cleaning improves visibility when using the wipers
considerably.
l Wash off the did from the underside (wheel
housings, fenders, etc.).
l In areas of high industrial fallout, more fre-
quent washing is recommended.
During high pressure washing the spray nonle
must never be closer to the vehicle than 13
inches (30cm). Do not spray into the locks.
l When washing or steam cleaning the engine,
avoid spraying water or steam directly on the electri-
cal components or near the distributor or ignition
components. After cleaning the engine, the spark
plug wells should be inspected for water and blown
dry if necessary. Automatic car washing is a simple and quick way
to clean your car, but it is worth remembering that it
is not as thorough as when you yourself clean the
car. Keeping the underbody clean is vitally important,
and some automatic washers do not contain equip-
ment for washing the underside of the car.
When driving into an automatic was, make sure
the following precautions have been taken:
l Make sure all windows are up, and no objects
that you do not want to get wet are exposed.
l In some cases, rotating the side view mirrors
in can help to avoid possible damage.
l If your car is equipped with a power antenna,
lower it. If your vehicle has a solid mounted, non-
power antenna, it is best to remove it, but this is not
always practical. Inspect the surroundings to reduce
the risk of possible damage, and check to see if the
antenna can be manually lowered.
Most manufacturers do not recommend auto-
matic car washing in the first six months due
to the possibility of insufficient paint curing;
a safe bet is to wait until after six months of
ownership (when purchased new) to use an
automatic car wash.
WAXING
eBefore applying wax, the vehicle must be
washed and thoroughly dried.
Waxing a vehicle can help to preserve the appear-
ante of your vehicle. A wide range of polymer-based
car waxes are available today. These waxes are easy
to use and produce a long-lasting, high gloss finish
that protects the body and paint against oxidation,
road dirt, and fading.
Sometimes, waxing a neglected vehicle, or one
that has sustained chemical or natural element dam-
age (such as acid rain) require more than waxing,
and a light-duty compound can be applied. For se-
verely damaged surfaces, it is best to consult a pro-
fessional to see what would be required to repair the
damage.
Waxing procedures differ according to manufac-
turer, type, and ingredients, so it is best to consult
the directions on the wax and/or polish purchased.

2. Pull the jumping vehicle (with the good bat-
tery) into a position so the jumper cables can reach
the dead battery and that vehicle’s engine. Make sure
that the vehicles do NOT touch.
3. Place the transmissions/transaxles of both ve-
hicles in Neutral (MT) or P (AT), as applicable, then
firmly set their parking brakes.
*ff necessary for safety reasons, the hazard
lights on both vehicles may be operated
throughout the entire procedure without sig-
nificantiy increasing the diff icuity of jumping
the dead battery.
4. Turn all lights and accessories OFF on both
vehicles. Make sure the ignition switches on both ve-
hicles are turned to the OFF position.
5. Cover the battery cell caps with a rag, but do
not cover the terminals.
6. Make sure the terminals on both batteries are
clean and free of corrosion or proper electrical con-
nection will be impeded. If necessary, clean the bat-
tery terminals before proceeding.
7. Identify the positive (+) and negative (-) termi-
nals on both batteries.
8. Connect the first jumper cable to the positive
(t) terminal of the dead battery, then connect the
other end of that cable to the positive (t) terminal of
the booster (good) battery.
9. Connect one end of the other jumper cable to
the negative (−) terminal on the booster bat-
tery and the final cable clamp to an engine bolt head,
alternator bracket or other solid, metallic point on the
engine with the dead battery. Try to pick a ground on
the engine that is positioned away from the battery in
order to minimize the possibility of the 2 clamps
touching should one loosen during the procedure.
DO NOT connect this clamp to the negative (-) termi-
nal of the bad battery. cable on the donor battery. Disconnect the positive
cable from the donor battery and finally, disconnect
the positive cable from the formerly dead battery. Be
careful when disconnecting the cables from the posi-
tive terminals not to allow the alligator clips to touch
any metal on either vehicle or a short and sparks will
occur.

Your vehicle was supplied with a jack for emer-
gency road repairs. This jack is fine for changing a
flat tire or other short term procedures not requiring
you to go beneath the vehicle. If it is used in an emergency situation, carefully follow the instructions
provided either with the jack or in your owners man-
ual. Do not attempt to use the jack on any portions of
the vehicle other than specified by the vehicle manu-
facturer. Always block the diagonally opposite wheel
when using a jack.
A more convenient way of jacking is the use of a
garage or floor jack. You may use the floor jack to
raise the front of the vehicle by placing it under the
front subframe. The rear of the vehicle is most easily
raised by using the lift points on the drip rail. All
models are equipped with lift points located on the
mid- crossmember in the front and a bracket located
on the floorpan underneath the trunk.
Never place the jack under the radiator, engine or
transaxle components. Severe and expensive damage
will result when the jack is raised. Additionally, never

Whenever you plan to work under the vehicle, you
must support it on jackstands or ramps. Never use
cinder blocks or stacks of wood to support the vehi-
cle, even if you’re only going to be under it for a few
minutes. Never crawl under the vehicle when it is
supported only by the tire-changing jack or other
*Always position a block of wood or small
rubber pad on top of the jack or jackstand to
protect the lifting point’s finish when lifting
or supporting the vehicle.
Small hydraulic, screw, or scissors jacks are satis-

Be very careful to keep the jumper cables
away from moving parts (cooling fan, belts,
etc.) on both engines.
10. Check to make sure that the cables are routed
away from any moving parts, then start the donor ve-
hicle’s engine. Run the engine at moderate speed for
several minutes to allow the dead battery a chance to
receive some initial charge.
11. With the donor vehicle’s engine still running
slightly above idle, try to start the vehicle with the
dead battery. Crank the engine for no more than 10 &stands also on the

seconds at a time and let the starter cool for at least
20 seconds between tries. If the vehicle does not start
in 3 tries, it is likely thatsomething else is also
wrong or that the battery needs additional time to
charge.
12. Once the vehicle is started, allow it to run at
idle for a few seconds to make sure that it is operat-
ing properly.
13. Turn ON the headlights, heater blower and, if
equipped, the rear defroster of both vehicles in order
to reduce the severity of voltage spikes and subse-
quent risk of damage to the vehicles’ electrical sys-
tems when the cables are disconnected. This step is
especially important to any vehicle equipped with
