your workbench. Some useful household items are: a
large turkey baster or siphon, empty coffee cans and
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
lmvl Fig. 15 Proper information is vital, so at
ways have a Chiiton Total Car Care manua
handy
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%
ton capacity, and at least two sturdy jackstands.

l-14 GENERALINFORMATIONAND MAINTENANCE
Proper maintenance and tune-up is the key to long
and trouble-free vehicle life, and the work can yield
its own rewards. Studies have shown that a properly
tuned and maintained vehicle can achieve better gas
mileage than an out-of-tune vehicle. As a conscien-
tious owner and driver, set aside a Saturday morning,
say once a month, to check or replace items which
could cause major problems later. Keep your own
personal log to jot down which services you per-
formed, how much the parts cost you, the date, and
the exact odometer reading at the time. Keep all re-
selfer, these receipts are the only proof you have that ceipts for such items as engine oil and filters, so that
they may be referred tp in case of related problems or
to determine operating expenses. As a do-it-your- the required maintenance was performed. In the event
of a warranty problem, these receipts will be invalu-
able.
The literature provided with your vehicle when it
was originally delivered includes the factory recom-
mended maintenance schedule. If you no longer have
this literature, replacement copies are usually avail-
able from the dealer. A maintenance schedule is pro-
vided later in this section, in case you do not have
the factory literature. *

ing motion and to maintain proper valve timing.
Some manufacturers schedule periodic timing belt
replacement to assure optimum engine performance,
to make sure the motorist is never stranded should
the belt break (as the engine will stop instantly) and
for some (manufacturers with interference motors) to
prevent the possibility of severe internal engine dam-
age
St10Ula the Delt break. Although the 1.5L and 1.8L engines are not listed
as an interference motors (it is not listed by the man-
ufacturer as a motor whose valves might contact the
pistons if the camshaft was rotated separately from
the crankshaft) the first 2 reasons for periodic re-
placement still apply and the timing belt should be
replaced at 60,000 miles (96,000 km). The 1.6L,
2.01,2.4L, 3.OL, and 35L engines are listed as inter-
ference motors, so the timing belt MUST be replaced
at 60,000 miles (96,000 km) to avoid severe engine
damage if the belt should break.
But whether or not you decide to replace the tim-
ing belt in the manufacturers schedule, you would be
wise to check it periodically to make sure it has not
become damaged or worn. Generally speaking, a se-
verelv worn belt mav cause enaine oerformance to
drop~dramatically, but a damaged belt (which could
give out suddenly) may not give as much warning. In
general, any time the engine timing cover(s) is (are)
removed you should inspect the belt for premature
parting, severe cracks or missing teeth. Also, an ac-
cess plug is provided in the upper portion of the tim-
ing cover so that camshaft timing can be checked
without cover removal. If timing is found to be off,
cover removal and further belt inspection or replace-
ment is necessary.

Upper and lower radiator hoses, along with the
heater hoses, should be checked for deterioration,
leaks and loose hose clamps at least every 30,000
miles (48,000 km). It is also wise to check the hoses
periodically in early spring and at the beginning of
the fall or winter when you are performing other
maintenance. A quick visual inspection could dis-
cover a weakened hose which might have left you
stranded if it had remained unrepaired.
Whenever you are checking the hoses, make sure
the engine and cooling system are cold. Visually in-
spect for cracking, rotting or collapsed hoses, and w-
place as necessary. Run your hand along the length
of the hose. If a weak or swollen spot is noted when
squeezing the hose wall, the hose should be re- Fig. 78 Foreign materials can get in be- Fig. 79 Inspect the timing belt for c

IEMOVAL &,INSTALLATION '
1. Remove the radiator pressure cap. her of the sorina tension tvoe (which reouire oliers
3 squeeze the 6bs and loosenj or of the’screw ten-
ion type (which require screw or hex drivers to
oosen). Pull the clamps back on the hose away from
he connection. Never remove the pressure cap while the en-
gine is running, or personal injury from
scalding hot coolant or steam may result. If
possible, wait until the engine has cooled to
remove the pressure cap. If this is not possi-
ble, wrap a thick cloth around the pressure
cap and turn it slowly to the stop. Step back
while the pressure is released from the cool-
ing system. When you are sure all the pres-
sure has been released, use the cloth to turn
and remove the cao.
2. Position a clean container under the radiator
and/or engine draincock or plug, then open the drain
and allow the cooling system to drain to an appropri-
ate level. For some upper hoses, only a little coolant
must be drained. To remove hoses positioned lower
on the engine, such as a lower radiator hose, the en-
tire cooling system must be emptied.
When draining coolant, keep in mind that
cats and dogs are attracted by ethylene gly-
col antifreeze, and are quite likely to drink
any that is left in an uncovered container or
in puddles on the ground. This will prove fa-
tal in sufficient quantity. Always drain
coolant into a sealable container. Coolant
may be reused unless it is contaminated or
several years old. 9. Close the radiator or engine drains and prop-
erly refill the cooling system with the clean drained
engine coolant or a suitable mixture of ethylene gly-
cot coolant and water.
10. If available, install a pressure tester and check
for leaks. If a pressure tester is not available, run the
engine until normal operating temperature is reached
(allowing the system to naturally pressurize), then
check for leaks.
If you are checking for leaks with the system
at normal operating temperature, BE EX-
TREMELY CAREFUL not to touch any moving
or hot engine parts. Once temperature has
been reached. shut the enaine OFF. and

odically flushed check for leaks around the-hose fittings and
connections which were removed earlier.
INSPECTION
b See Figures 88 and 87
The CV (Constant Velocity) boots should be
checked for damage each time the oil is changed and
any other time the vehicle is raised for service. These
boots keep water, grime, dirt and other damaging
matter from entering the CV-joints. Any of these
could cause early CV-joint failure which can be ex-
pensive to repair. Heavy grease thrown around the in-
side of the front wheel(s) and on the brake
caliper/drum can be an indication of a torn boot.
Thorouahlv check the boots for missina clamos and 3. Loosen the hose clamps at each end of the

4. Twist, pull and slide the hose off the fitting,
sking care not to damage the neck of the component
rom which the hose is being removed.
*If the hose is stuck at the connection, do
lot try to insert a screwdriver or other sharp
ool under the hose end in an eff art to free it,
IS the connection and/or hose may become
lamaged. Heater connections especially
nay be easily damaged by such a procedure.
f the hose is to be replaced, use a single-
!dged razor blade to make a slice along the
lortion of the hose which is stuck on the con-
section, perpendicular to the end of the
