ice trays (to store parts), ball of twine, electrical tape
for wiring, small rolls of colored tape for tagging lines
or hoses, markers and pens, a note pad, golf tees (for
plugging vacuum lines), metal coat hangers or a roll
of mechanic’s wire (to hold things out of the way),
dental pick or similar long, pointed probe, a strong
magnet, and a small mirror (to see into recesses and
under manifolds).
A more advanced set of tools, suitable for tune-up
work, can be drawn up easily. While the tools are

l Feeler aauoes for valve adiustment
* 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.

l Do be sure that adjustable wrenches are
tightly closed on the nut or bolt and pulled so that
the force is on the side of the fixed jaw.
l Do strike squarely with a hammer; avoid glanc-
ing blows. l Don’t run the engine in a garage or anywhere
else without proper ventilation-EVER! Carbon monoxide is poisonous; it takes a long time to leave
the human body and you can build up a deadly sup-
ply of it in your system by simply breathing in a !ittle
every day. You may not realize you are slowly poi-
soning yourself. Always use power vents, windows,
fans and/or open the garage door.
l Don’t work around moving parts while wearing
loose clothing. Short sleeves are much safer than
long, loose sleeves. Hard-toed shoes with neoprene
soles protect your toes and give a better grip on slip-
pery surfaces. Jewelry such as watches, fancy belt
buckles, beads or body adornment of any kind is not
safe working around a vehicle. Long hair should be
tied back under a hat or cap.
l Don’t use pockets for toolboxes. A fall or bump
can drive a screwdriver deep into your body. Even a
rag hanging from your back pocket can wrap around
a spinning shaft or fan.
l Don’t smoke when working around gasoline,
cleaning solvent or other flammable material.
l Don’t smoke when workrng around the battery.
When the battery is being charged, it gives off explo-
sive hydrogen gas.
l Don’t use gasoline to wash your hands; there
are excellent soaps available. Gasoline contains dan-
gerous additives which can enter the body through a
cut or through your pores. Gasoline also removes all
the natural oils from the skin so that bone dry hands
will suck up oil and grease.
l Don’t service the air conditioning system un-
less you are equipped with the necessary tools and
trainmg. When liquid or compressed gas refrigerant
is released to atmospheric pressure it will absorb
heat from whatever it contacts. This will chill or freeze
anything it touches.
l Don’t use screwdrivers for anything other than
driving screws! A screwdriver used as an prying tool
can snap when you least expect it, causing injuries.
At the very least, you’ll ruin a good screwdriver.
. Don’t use an emergency jack (that little ratchet,
scissors, or pantograph jack supplied with the vehi-
cle) for anything other than changing a flat! These
jacks are only Intended for emergency use out on the
road; they are NOT designed as a maintenance tool. If
you are serious about mamtaining your vehicle your-
self, invest in a hydraulic floor jack of at least a 1%

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.

OFF. 8. Remove the jumper wire from the ignition
timing adjusting terminal and install the water-proof
cover.
9. Start the engine and check the actual timing
(the timing without the terminal grounded). This
reading should be approximately 5 degrees more
than the basic timing. Actual timing may increase ac-
cording to altitude. Also, actual timing may fluctuate
because of slight variation accomplished by the ECU.

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

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-
factory for raising the vehicle. Drive-on trestles or
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
Fig. 225 The most practical place to place
front of the vehicle is
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
computer control modules.

order of connection. Start with the negative cable that
is attached to the engine ground, then the negative Fig. 226 Place the jackstands also
