1996 TOYOTA SUPRA service

144You can be confident that your Toyota
dealer's service department performs the
best
job to meet the maintenance require-
ments on your vehicleÐreliably and eco-
nomically.
Your copy of the repair order is proof that
all required maintenance has been per-
formed for warranty coverage. And if any
problems should arise with your vehicle
while under warranty, your Toyota dealer
will promptly take care of it. Again, be sure
to keep a copy of the repair order for any
service performed on your Toyota.
What about do-it-yourself mainte- nance?
Many of the maintenance items are easy
to do yourself if you have a little mechani-
cal ability and a few basic automotive
tools. Simple instructions for how to per-
form them are presented in Part 7.
If you are a skilled do-it-yourself me-
chanic, the Toyota service manuals are recommended. Please be aware that do-
it-yourself maintenance can affect your
warranty coverage. See Owner's Guide,
Owner 's Manual Supplement or W arranty
Booklet for the details. Listed
below are the general maintenance
items that should be performed as fre- quently as specified. In addition to check-
ing the items listed, if you notice any un-
usual noise, smell or vibration, you should
investigate the cause or take your vehicle
to your T oyota dealer or a qualified service
shop immediately. It is recommended thatany problem you notice be brought to theattention of your dealer or the qualified service shop for their advice.
Make these checks only where
adequate ventilation can be ob-
tained if you run the engine. CAUTION

evel on the dipstick with the en-
gine turned off and the vehicle parked on
a level spot. See Chapter 7-2 for addition-
al information. Power steering fluid level Check the level on the dipstick. The level
should be in the HOTº or COLDº range
depending on the fluid temperature. See Chapter 7-2 for additional information. Exhaust system
If you notice any change in the sound of
the exhaust or smell exhaust fumes, have the cause located and corrected immedi-
ately. (See engine exhaust cautions in
Part 2.)

146Be on the alert for changes in perfor-
mance, sounds, and visual tip-offs
that in-
dicate service is needed. Some important
clues are as follows: Engine missing, stumbling, or pinging
Appreciable loss of power
Strange engine noises
A leak under the vehicle (however, wa-
ter dripping from the air conditioning
after use is normal.)
Change in exhaust sound (This may
indicate a dangerous carbon monox-
ide leak. Drive with the windows open
and have the exhaust system checked
immediately.)
Flat-looking tire; excessive tire squeal
when cornering; uneven tire wear
Vehicle pulls to one side when driving straight on a level road
Strange noises related to suspensionmovement
Loss of brake effectiveness; spongy
feeling brake or clutch pedal; pedal al-
most touches floor; vehicle pulls to one
side when braking
Engine coolant temperature continual-
ly higher than normal If you notice any of these clues, take your
vehicle to your Toyota dealer as soon as
possible. It probably needs adjustment or
repair.
Do not continue driving with the
vehicle unchecked. It could result
in serious vehicle damage and
pos-
sibly personal injury. CAUTION

If you perform maintenance by your-
self, be sure to follow the correct pro- cedure given in this part.
You should be aware that improper or in- complete servicing may result in operat-
ing problems.
Performing do-it-yourself maintenance
during the warranty period may affect your warranty coverage. Read the sepa-
rate Toyota Warranty statement for details
and suggestions.
This part gives instructions only for those
items that are relatively easy for an owner
to perform. As explained in Part 6, there
are still a number of items that must be
done by a qualified technician with special
tools.
For information on tools and parts for do-
it-yourself maintenance, see Parts andtoolsº.
Utmost care should be taken when work-
ing on your vehicle to prevent accidental
injury. Here are a few pr ecautions that you
should be especially careful to observe:
Do-it-yourself service precautions
Fuse locations

151
When the engine is running, keep
hands, clothing, and tools away
from the moving fan and engine
drive belts. (Removing rings,
watches, and ties is advisable.)
Right after driving, the engine
compartmentÐthe engine, radia-
tor, exhaust manifold, power
steering fluid reservoir and spark
plug boots, etc.Ðwill be hot. So be
careful not to touch them. Oil,
fluids and spark plugs may also be
hot.
If the engine is hot, do not remove
the radiator cap or loosen the
drain plugs to prevent burning yourself.
Do not smoke, cause sparks or al-
low open flames around fuel or
the battery. Their fumes are flam- mable.
Be extremely cautious when
working on the battery. It contains
poisonous and corrosive sulfuricacid.
Do not get under your vehicle with
just the body jack supporting it.
Always use automotive jack
stands or other solid supports. CAUTION
!
Be sure that the ignition is off if you
work near the electric cooling fans
or radiator grille. With the ignition
on, the electric cooling fan will au-
tomatically start to run if the engine
coolant temperature is high and/or
the air conditioning is on.
Use eye protection whenever you
work on or under your vehicle
where you may be exposed to fly-
ing or falling material, fluid spray,etc.
Used engine oil contains potential-
ly harmful contaminants which
may cause skin disorders such as
inflammation or skin cancer, so
care should be taken to avoid pro-
longed and repeated contact with
it. To remove used engine oil from
your skin, wash thoroughly with
soap and water.
Do not leave used oil within the reach of children.
Dispose of used oil and filter only
in a safe and acceptable manner.
Do not dispose of used oil and fil-
ter in household trash, in sewers
or onto the ground. Call your deal-
er or a service station for informa-
tion concerning recycling or dis- posal.
Remember that battery and igni-
tion cables carry high currents or
voltages. Be careful of accidental-
ly causing a short circuit.
Add only demineralized or dis-tilled water to fill the radiator. And
if you spill some of the coolant, besure to wash it off with water to
prevent it from damaging the
parts or paint.
Do not overfill automatic trans-mission fluid, or the transmission
could be damaged.
Do not drive with the air cleaner fil-ter removed, or excessive enginewear could result. Also backfiringcould cause a fire in the engine
compartment.
Be careful not to scratch the glasssurface with the wiper frame.
When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.
NOTICE

154ENGINE OIL SELECTION 2JZ-GE engineÐUse API SH, Energy-
Conserving IIº multigrade engine oil or
IL SAC multigrade engine oil.
SAE 5W-30 is the best choice for your
vehicle, for good fuel economy, and
good starting in cold weather.
If you use SAE 10W-30 engine oil in
extremely low temperatures, the en-
gine may become difficult to start, so
SAE 5W-30 engine oil is recom-mended.
2JZ-GTE
engineÐUse API SH, Energy-
Conserving IIº multigrade engine oil or
IL SAC multigrade engine oil.If you use SAE 10W-30 engine oil in
extremely low temperatures, the en-
gine may become difficult to start, so
SAE 5W-30 engine oil is recom-mended.
Oil identification marks
Either or both API registered marks are
added to some oil containers to help
you select the oil you should use.
The API Service Symbol is located any-
where on the outside of the container. The top portion of the label shows the oil
quality by API (American Petroleum Insti-
tute) designations such as SH. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W-30. Energy-
Conserving IIº shown in the lower portion,
indicates that the oil has fuel-saving capa-
bilities. Oils marked Energy-Conserving
IIº will have higher fuel-saving capabilities than oil marked Energy-Conservingº.
