ENGINE OIL INSPECTION
1. CHECK OIL QUALITY
Check the oil for deterioration, entry of water, dis±
coloring or thinning.
If oil quality is visibly poor, replace it.
Oil grade:
API grade SG or SH, Energy Conserving II multi±
grade engine oil or ILSAC multigrade engine oil.
Recommended viscosity is as shown in the illustra±
tion.
TUNE±UP
ENGINE COOLANT INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
TANK
The engine coolant level should be between the
ªLOWº and ªFULLº lines at low temperature.
If low, check for leaks and add engine coolant up to
the ªFULLº
2. CHECK ENGINE COOLANT QUALITY
There should be no excessive deposits of rust or
scales around the radiator cap or radiator filler hole,
and the engine coolant should be free from oil.
If excessively dirty, replace the engine coolant.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ªLº and ªFº marks
on the dipstick.
If low, check for leakage and add oil up to the ªFº
mark.

ELECTRONIC CONTROL SYSTEM
1. Before removing MFI/SFI wiring connectors, termi±
nals, etc., first disconnect the power by either turning
the ignition switch OFF or disconnecting the battery
terminals.
HINT: Always check the diagnostic trouble code
before disconnecting the negative (±) terminal cable
from the battery.
2. When installing the battery, be especially careful not
to incorrectly connect the positive (+) and negative
(±) cables.
3. Do not permit parts to receive a severe impact during
removal or installation. Handle all MFI/SFI parts care±
fully, especially the ECM.
4. Do not be careless during troubleshooting as there are
numerous transistor circuits and even slight terminal
contact can further troubles.
5. Do not open the ECM cover.
6. When inspecting during rainy weather, take care to
prevent entry of water. Also, when washing the
engine compartment, prevent water from getting on
the MFI/SFI parts and wiring connectors.
7. Parts should be replaced as an assembly.
AIR INDUCTION SYSTEM
1. Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to run out of tune.
2. Disconnection, looseness or cracks in the parts of the
air induction system between the throttle body and
cylinder head will allow air suction and cause the
engine to run out of tune.
IF VEHICLE IS EQUIPPED WITH MOBILE
RADIO SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communica±
tion system, refer to the precaution in the IN section.

7. CHECK ENGINE OIL LEVEL
The oil level should be between the ªLº and ªFº marks
on the dipstick.
If low, check for leakage and add oil up to ªFº mark. (c) Tighten the oil filter by hand until the rubber gasket
contacts the seat of the filter mounting. Then using
SST, give it an additional 3/4 turn to seat the oil filter.
SST 09228±06500
4. FILL WITH ENGINE OIL
5. FILL WITH ENGINE COOLANT (SEE PAGE EG1±241)
6. START ENGINE AND CHECK FOR LEAKS 3. INSTALL OIL FILTER
(a) Clean the oil filter contact surface on the filter
mounting.
(b) Lubricate the filter rubber gasket with engine oil.
± 5S±FE ENGINECOOLING SYSTEMEG1±249

A pressure feeding lubrication system has been adopted to supply oil to the moving parts of this
engine. The lubrication system consists of an oil pan, oil pump, oil filter and other external parts
which supply oil to the moving parts in the engine block. The oil circuit is shown in the illustration
at the top of the previous page. Oil from the oil pan is pumped up by the oil pump. After it passes
through the oil filter, it is through the various oil holes in the crankshaft and cylinder block. After
passing through the cylinder block and performing its lubricating function, the oil is returned by
gravity to the oil pan. A dipstick on the center left side of the cylinder block is provided to check
the oil level.
OIL PUMP
The oil pump pumps up oil from the oil pan and feeds it under pressure to the various parts of the
engine. An oil strainer is mounted in front of the inlet to the oil pump to remove impurities. The
oil pump itself is a trochoid type pump, inside of which is a drive rotor and a driven rotor. When
the drive rotor rotates, the driven rotor rotates in the same direction, and since the axis of the
drive rotor shaft is different from the center of the driven rotor, the space between the two rotors
changes as they rotate. Oil is drawn in when the space widens and is discharged when the space
becomes narrow.
OIL PRESSURE REGULATOR (RELIEF VALVE)
At high engine speeds, the engine oil supplied by the oil pump exceeds the capacity of the engine
to utilize it. For that reason, the oil pressure regulator works to prevent an oversupply of oil.
During normal oil supply, a coil spring and valve keep the bypass closed, but when too much oil
is being fed, the pressure becomes extremely high, overpowering the force of the spring and
opening the valves. This allows the excess oil to flow through the valve and return to the oil pan.
OIL FILTER
The oil filter is a full flow type filter with a relief valve built into the paper filter element. Particles
of metal from wear, airborne dirt, carbon and other impurities can get into the oil during use and
could cause accelerated wear or seizing if allowed to circulate through the engine. The oil filter,
integrated into the oil line, removes these impurities as the oil passes through it. The filter is
mounted outside the engine to simplify replacement of the filter element. A relief valve is also
included ahead of the filter element to relieve the high oil pressure in case the filter element
becomes clogged with impurities. The relief valve opens when the oil pressure overpowers the
force of the spring. Oil passing through the relief valve bypasses the oil filter and flows directly
into the main oil hole in the engine.

CAUTION
It is dangerous to continue driving
normally when the brake fluid level is
low.
If the brake fluid level is correct...
Have the warning system checked by your
Toyota dealer.
(b) Seat Belt Reminder Light and Buzz-
er
Once the ignition key is turned to ºONº or
ºSTARTº, the reminder light and buzzer
come on if the driver's seat belt is not
fastened. Unless the driver fastens the
belt, the light stays on and the buzzer
stops after about 4 to 8 seconds.
(c) Discharge Warning Light
This light warns that the battery is being
discharged.
If it comes on while you are driving, there
is a problem somewhere in the charging
system.
The engine ignition will continue to oper-
ate, however, until the battery is dis-
charged. Turn off the air conditioning,
blower, radio, etc., and drive directly to
the nearest Toyota dealer or repair shop.
NOTICE
Do not continue driving if the engine
drive belt is broken or loose.
(d) Malfunction Indicator Lamp
This lamp comes on in the following
cases.
a. The fuel tank is completely empty. (See
ºFuel gaugeº in Chapter 1±5 for instruc-
tions.)
b. The fuel tank cap is not tightened se-
curely. (See ºFuel tank capº in Chapter
1±2 for instructions.)
c. There is a problem somewhere in your
engine or automatic transmission electrical
system.
If it comes on while you are driving in
case c, have your vehicle checked/re-
paired by your Toyota dealer as soon as
possible.
(e) Low Fuel Level Warning Light
This light comes on when the fuel level
in the tank becomes nearly empty. Fill up
the tank as soon as possible.
On inclines or curves, due to the move-
ment of fuel in the tank, the low fuel level
warning light may come on earlier than
usual.(f) Low Oil Pressure Warning Light
This light warns that the engine oil pres-
sure is too low.
If it flickers or stays on while you are
driving, pull off the road to a safe place
and stop the engine immediately. Call a
Toyota dealer or qualified repair shop for
assistance.
The light may occasionally flicker when
the engine is idling or it may come on
briefly after a hard stop. There is no
cause for concern if it then goes out when
the engine is accelerated slightly.
The light may come on when the oil level
is extremely low. It is not designed to
indicate low oil level, and the oil level
must be checked using the level dipstick.
NOTICE
Do not drive the vehicle with the
warning light onÐeven for one block.
It may ruin the engine.
