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.

DESCRIPTION
The 5S±FE engine model uses the same S51 manual transaxle as in the previous model.
The 1MZ±FE engine model ahs newly adopted the E153 manual transaxle. The basic construction and operation
of the E153 manual transaxle are the same as those of the '95 MR2. However, the differential gear ratio has been
changed to accommodate the characteristics of the engine.

FUNCTIONS OF ENGINE OIL
Engine oil has the primary functions of
lubricating and cooling the inside of the
engine, and plays a major role in main-
taining the engine in proper working order.
ENGINE OIL CONSUMPTION
It is normal that an engine should con-
sume some engine oil during normal
engine operation. The causes of oil
consumption in a normal engine are as
follows.
Oil is used to lubricate pistons, piston
rings and cylinders. A thin film of oil
is left on the cylinder wall when a pis-
ton moves downwards in the cylinder.
High negative pressure generated when
the vehicle is decelerating sucks some
of this oil into the combustion chamber.
This oil as well as some part of the oil
film left on the cylinder wall is burned
by the high temperature combustion
gases during the combustion process.
Oil is also used to lubricate the stems
of the intake valves. Some of this oil
is sucked into the combustion chamber
together with the intake air and is
burned along with the fuel. High tem-
perature exhaust gases also burn the
oil used to lubricate the exhaust valve
stems.
The amount of engine oil consumed de-
pends on the viscosity of the oil, the
quality of the oil and the conditions the
vehicle is driven under.
More oil is consumed by high±speed driv-
ing and frequent acceleration and decel-
eration.
A new engine consumes more oil, since
its pistons, piston rings and cylinder walls
have not become conditioned.
When judging the amount of oil con-
sumption, note that the oil may become
diluted and make it difficult to judge
the true level accurately.
As an example, if a vehicle is used for
repeated short trips, and consumes a nor-
mal amount of oil, the dipstick may not
show any drop in the oil level at all, even
after 1000 km (600 miles) or more. This
is because the oil is gradually becoming
diluted with fuel or moisture, making it
appear that the oil level has not changed.The diluting ingredients evaporate out
when the vehicle is then driven at high
speeds, as on an express way, making it
appear that oil is excessively consumed
after driving at high speeds.
IMPORTANCE OF ENGINE OIL LEVEL
CHECK
One of the most important points in prop-
er vehicle maintenance is to keep the en-
gine oil at the optimum level so that oil
function will not be impaired. Therefore, it
is essential that the oil level be checked
regularly. Toyota recommends that the oil
level be checked every time you refuel
the vehicle.
NOTICE
Failure to check the oil level regularly
could lead to serious engine trouble
due to insufficient oil.
For detailed information on oil level check,
see ºChecking the engine oil levelº in
Chapter 7±2.

Tire surface and wheel nuts
Check the tires carefully for cuts, damage
or excessive wear. See Chapter 7±2 for
additional information. When checking the
tires, make sure no nuts are missing, and
check the nuts for looseness. Tighten
them if necessary.
Tire rotation
Rotate the tires every 12000 km (7500
miles). See Chapter 7±2 for additional in-
formation.
Fluid leaks
Check underneath for leaking fuel, oil, wa-
ter or other fluid after the vehicle has
been parked for a while. If you smell fuel
fumes or notice any leak, have the cause
found and corrected immediately.
Doors and engine hood
Check that all doors including trunk lid
operate smoothly and all latches lock se-
curely. Make sure the engine hood sec-
ondary latch secures the hood from open-
ing when the primary latch is released.
INSIDE THE VEHICLE
Items listed below should be checked
regularly, e.g. while performing periodic
services, cleaning the vehicle, etc.Lights
Make sure the headlights, stop lights, tail
lights, turn signal lights, and other lights
are all working. Check headlight aim.
Service reminder indicators and warning
buzzers
Check that all service reminder indicators
and warning buzzers function properly.
Steering wheel
Be alert for changes in steering condition,
such as hard steering or strange noise.
Seats
Check that all front seat controls such as
seat adjusters, seatback recliner, etc. op-
erate smoothly and that all latches lock
securely in any position. Check that the
head restraints move up and down
smoothly and that the locks hold securely
in any latched position. For folding±down
rear seatbacks, check that the latches
lock securely.
Seat belts
Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly. Make sure that the
belt webbings not cut, frayed, worn or
damaged.Accelerator pedal
Check the pedal for smooth operation and
uneven pedal effort or catching.
Clutch pedal
Check the pedal for smooth operation.
Brake pedal
Check the pedal for smooth operation and
that the pedal has the proper clearance.
Check the brake booster function.
Brakes
At a safe place, check that the brakes do
not pull to one side when applied.
Parking brake
Check that the lever has the proper travel
and that, on a safe incline, your vehicle
is held securely with only the parking
brake applied.
Automatic transmission ºParkº mecha-
nism
Check the lock release button of the se-
lector lever for proper and smooth opera-
tion. On a safe incline, check that your
vehicle is held securely with the selector
lever in ºPº position and all brakes re-
leased.
