OIL PRESSURE CHECK
1. CHECK OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or
thinning.
If oil quality is visibly poor, replace the oil.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ºLº and ºFº marks on the
dipstick.
If low, check for the leakage and add oil up to ºFº mark.
3. REMOVE ENGINE UNDER COVER
4. 2JZ±GTE:
REMOVE NO.2 AIR TUBE
Loosen the 2 hose clamps, and remove 2 bolts and air tube.
5. 2JZ±GTE M/T:
REMOVE DRIVE BELT TENSIONER DAMPER
Remove the 2 nuts and tensioner damper.
6. DISCONNECT A/C COMPRESSOR FROM ENGINE

There are some maintenance and inspection
items which are considered to be the owner's re-
sponsibility. They can be performed by the owner
or be can have them done at a service shop.
These items include those which should be
checked on a daily basis, those which, in most
cases, do not require (special) tools and those
which are considered to be reasonable for the
owner to perform. Items and procedures for gen-
eral maintenance are as follows:
OUTSIDE VEHICLE
1. TIRES
(a) Check the pressure with a gauge. Adjust if
necessary.
(b) Check for cuts, damage, uneven or excessive
wear.
2. WHEEL NUTS
When checking the tires, check the nuts for
looseness or for missing nuts. If necessary,
tighten them.
3. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not
wipe clean. Replace if necessary.
4. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or
other fluid.
(b) If you smell gasoline fumes or notice any leak,
have the cause found and corrected.
5. DOORS AND ENGINE HOOD
(a) Check that all doors including the trunk lid
operate smoothly, and that all latches lock
securely.
(b) Check that the engine hood secondary latch
secures the hood from opening when the
primary latch is released.
INSIDE VEHICLE
6. LIGHTS
(a) C h e c k t h a t t h e headlights, stop lights,
tail±lights, turn signal lights, and other lights
are all working.
(b) Check the headlight aiming.7. WARNING LIGHT AND BUZZERS
Check that all warning lights and buzzers
function properly.
8. HORN
Check that it is working.
9. WINDSHIELD GLASS
Check for scratches, pits or abrasions.
10. WINDSHIELD WIPER AND WASHER
(a) Check operation of the wipers and washer.
(b) Check that the wipers do not streak.
11. WINDSHIELD DEFROSTER
Check that the air comes out from the defrost-
er outlet when operating the heater air condi-
tioner at defroster mode.
12. REAR VIEW MIRROR
Check that it is mounted securely.
13. SUN VISORS
Check that they move freely and are
mounted securely.
14. STEERING WHEEL
Check that it has the specified freeplay. Be
alert for changes in steering condition, such
as excessive steering effort, excessive free-
play or strange noise.
15. SEATS
(a) Check that all front seat controls such as seat
adjusters, seatback recliner, etc. operate
smoothly.
(b) Check that all latches lock securely in any
position.
(c) Check that the locks hold securely in any
latched position.
(d) Check that the head restraints move up and
down smoothly and that the locks hold
securely in any latched position.
(e) For folding±down rear seat backs, check that
the latches lock securely.
16. SEAT BELTS
(a) Check that the seat belt system such as
buckles, retractors and anchors operate
properly and smoothly.
(b) Check that the belt webbing is not cut, frayed,
worn or damaged.
17. ACCELERATOR PEDAL
Check the pedal for smooth operation and
uneven pedal effort or catching.

COMPRESSION CHECK
HINT: If there is lack of power, excessive oil consumption or
poor fuel economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating tempera-
ture.
2. 2JZ±GE:
DISCONNECT DISTRIBUTOR CONNECTOR
3. 2JZ±GTE:
DISCONNECT CAMSHAFT POSITION SENSOR CON-
NECTORS
4. 2JZ±GE:
DISCONNECT HIGH±TENSION CORDS FROM SPARK
PLUGS
(See high±tension cords and cord clamps removal in
Ignition System)
5. 2JZ±GTE:
REMOVE IGNITION COILS ASSEMBLIES
(See ignition coils removal in Ignition System)
6. REMOVE SPARK PLUGS
7. CHECK CYLINDER COMPRESSION
(a) Insert a compression tester into the spark plug hole.
(b) Wh ile cra n kin g th e en g in e , me a su re th e co mp re ssio n
pressure.
HINT: Always use a fully charged battery to obtain engine rev-
olutions of 250 rpm or more.
(c) Repeat steps (a) through (b) for each cylinder.
NOTICE: This measurement must be done in as short a time as
possible.
Standard pressure:
2JZ±GE
1,275 kPa (13.0 kgf/cm
2, 185 psi) or more
2JZ±GTE
1,079 kPa (11.0 kgf/cm
2, 156 psi) or more
Minimum pressure:
2JZ±GE
1,079 kPa (11.0 kgf/cm
2, 156 psi)
2JZ±GTE
883 kPa (9.0 kgf/cm
2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
(d) If the cylinder compression in 1 or more cylinders is low, pour
a small amount of engine oil into the cylinder through the
spark plug hole and repeat steps (a) through (b) for the
cylinder with low compression.
± ENGINEENGINE MECHANICALEG±9

wIf adding oil helps the compression, it is likely that the
piston rings and/or cylinder bore are probably worn or
damaged.
wIf pressure stays low, a valve may be sticking or seating
improper, or there may be leakage past the gasket.
