CAUTION
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, radiator,
exhaust manifold, power steering
fluid reservoir and spark plug
boots, etc.Ðwill be hot. So be care-
ful 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 flammable.
Be extremely cautious when work-
ing on the battery. It contains poi-
sonous and corrosive sulfuric acid.
Do not get under your vehicle with
just the body jack supporting it. Al-
ways use automotive jack stands or
other solid supports.
Be sure that the ignition is off if
you work near the electric cooling
fan or radiator grille. With the igni-
tion on, the electric cooling fan will
automatically start to run if the en-
gine 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 flying
or falling material, fluid spray, etc.
Used engine oil contains potentially
harmful contaminants which may
cause skin disorders such as in-
flammation or skin cancer, so care
should be taken to avoid prolonged
and repeated contact with it. To re-
move 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 dealer or
a service station for information
concerning recycling or disposal.
NOTICE
Remember that battery and ignition
cables carry high currents or volt-ages. Be careful of accidentallycausing a short circuit.
Add only demineralized or distilled water to fill the radiator. And if youspill some of the coolant, be sure
to wash it off with water to preventit from damaging the parts or paint.
Do not overfill automatic transmis-sion fluid, or the transmission
could be damaged.
Do not drive with the air cleaner filter removed, or excessive engine
wear could result. also backfiringcould cause s fire in the engine compartment.

Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,check to see that you have not for-
gotten any tools, rags, etc.
Parts and tools
Here is a list of parts and tools you will
need on performing do- it- yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
Checking the engine oil level
Parts (if level is low):
Engine oil API grade SH,
ºEnergy- Conserving IIº or SJ,
ºEnergy- Conservingº multigrade or
ILSAC multigrade having viscosity
proper for your climate
Tools:
Rag or paper towel
Funnel (only for adding oil)
Checking the engine coolant level
Parts (if level is low): Ethylene- glycol antifreeze
Demineralized or distilled water
Tools: Funnel (only for adding coolant)
Checking brake fluid
Parts (if level is low):
SAE J1703 or FMVSS No.116 DOT 3
brake fluid Tools:
Rag or paper towel
Funnel (only for adding fluid)
Checking power steering fluid
Parts (if level is low): Automatic transmission fluid DEX- RON II or III
Tools: Rag or paper towel
Funnel (only for adding fluid)
Checking battery condition
Tools:
Warm water
Baking soda
Grease
Conventional wrench (for terminal
clamp bolts)
Checking and replacing fuses
Parts (if replacement is necessary): Fuse with same amperage rating as
original

Checking the engine oil level
60040F11
With the engine at operating tempera-
ture and turned off, check the oil level
on the dipstick. 1. To get a true reading, the vehicle should be on a level spot. After turning
off the engine, wait a few minutes for
the oil to drain back into the bottom of
the engine.
2. Pull out the dipstick, and wipe it clean with a rag.
3. Reinsert the dipstickÐpush it in as far as it will go, or the reading will not be
correct.
4. Pull the dipstick out and look at the oil level on the end. If the oil level is below or only slightly
above the low level, add engine oil of
the same type as already in the engine.
Remove the oil filler cap and add engine
oil in small quantities at a time, checking
the dipstick.
The approximate quantity of oil needed to
fill between the low level and the full level
on the dipstick is indicated below for ref-
erence.
When the level reaches within the correct
range, install the f
iller cap hand- tight.
Oil quantity, L (qt., lmp. qt.): 1.5 (1.6, 1.3)
NOTICE
Avoid overfilling, or the engine could be damaged.
Check the oil level on the dipstickonce again after adding the oil.

ENGINE OIL SELECTION
2JZ- GE engineÐUse API grade SH,
ºEnergy- Conserving IIº or SJ,
ºEnergy- Conservingº multigrade engine oil
or ILSAC multigrade engine oil.
Recommended viscosity (SAE):
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 engine
may become difficult to start, so SAE
5W- 30 engine oil is recommended.
2JZ- GTE engineÐUse API grade SH,
ºEnergy- Conserving IIº or SJ, ºEnergy-
Conservingº multigrade engine oil or
ILSAC multigrade engine oil.
Recommended viscosity (SAE):
If you use SAE 10W- 30 engine oil in
extremely low temperatures, the engine
may become difficult to start, so SAE
5W- 30 engine oil is recommended.
API service symbol
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 SJ. The center
portion of the label shows the SAE viscos-
ity grade such as SAE 5W- 30. ºEnergy-
Conservingº shown in the lower portion,
indicates that the oil has fuel- saving ca-
pabilities.

SUPRA (U)163
ILSAC certification mark
The ILSAC (International Lubricant Stan-
dardization and Approval Committee) Certi-
fication Mark is displayed on the front of
the container. Look at the see- through coolant reser-
voir when the engine is cold. The cool-
ant level is satisfactory if it is between
the ºFULLº and ºLOWº lines on the
reservoir. If the level is low, add ethyl-
ene- glycol type coolant.
The coolant level in the reservoir will vary
with engine temperature. However, if the
level is on or below the ºLOWº line, add
coolant. Bring the level up to the ºFULLº
line.
Use only ethylene- glycol type coolant.
See information in the next column.
If the coolant level drops within a short
time after replenishing, there may be a
leak in the system. Visually check the
radiator, hoses, radiator cap and drain
cock and water pump.
If you can find no leak, have your Toyota
dealer test the cap pressure and check
for leaks in the cooling system.
CAUTION
To prevent burning yourself, do not
remove the radiator cap when the en-
gine is hot.
Coolant type selection
Your coolant must contain ethylene- glycol
antifreeze. In addition to preventing freez-
ing and subsequent damage to the engine,
this will also prevent corrosion. Further
supplemental inhibitors or additives are
neither needed nor recommended.
Read the antifreeze container for informa-
tion on freeze protection. Follow the
manufacturer 's directions for how much to
mix with water. The total capacity of the
cooling system is given in Part 8. We
recommend 50% solution be used for your
Toyota, or a sufficient quantity to provide
protection to about -35
5C (- 31 5F).
NOTICE
Do not use alcohol type antifreeze or
plain water alone.
