Engine Oil and Filter Change
WARNING:
New and used engine oil can be hazardous.
Be sure to read “WARNING” in General Precaution in SEC-
TION 0A and observe what in written there.
Use engine oil of SE, SF, SG, SH or SJ grade.
Select the appropriate oil viscosity according to the left chart.
Before draining engine oil, check engine for oil leakage. If any evi-
dence of leakage is found, make sure to correct defective part be-
fore proceeding to following work.
1) Drain engine oil by removing drain plug.
2) After draining oil, wipe drain plug clean. Reinstall drain plug, and
tighten it securely as specified below.

tacts mounting surface.
CAUTION:
To tighten oil filter properly, it is important to accurately
identify the position at which filter O-ring first contacts
mounting surface.

1) Remove radiator cap when engine is cool.
2) Loosen radiator drain plug (1) to drain coolant.
3) Remove reservoir and drain.
4) Tighten drain plug securely. Also install reservoir.
5) Slowly pour specified amount of coolant to the base of radiator
filler neck, and run engine, with radiator cap removed, until ra-
diator upper hose is hot. This drives out any air which may still
be trapped within cooling system. Add coolant as necessary un-
til coolant level reaches filler throat of radiator. Reinstall radiator
cap.
6) Add coolant to reservoir (1) so that its level aligns with Full mark
(2). Then, reinstall cap to reservoir aligning match marks (3) on
reservoir and cap.

Exhaust System Inspection
WARNING:
To avoid danger of being burned, do not touch exhaust sys-
tem when it is still hot.
Any service on exhaust system should be performed when
it is cool.
When carrying out periodic maintenance or vehicle is raised for oth-
er service, check exhaust system as follows:
Check rubber mountings for damage and deterioration.
Check exhaust system for leakage, loose connections, dents,
and damages.
If bolts or nuts are loose, tighten them to specification. Refer to
SECTION 6K for torque specification of bolts and nuts.
Check nearby body areas for damaged, missing or mispositioned
parts, open seams, holes, loose connections or other defects
which could permit exhaust fumes to seep into vehicle.
Make sure that exhaust system components have enough clear-
ance from underbody to avoid overheating and possible damage
to floor carpet.
Any defects should be fixed at once.

Propeller Shaft Inspection (4WD vehicle only)
1) Check propeller shaft connecting bolts for looseness. If loose-
ness is found, tighten to specified torque.
2) Check propeller shaft joints for wear, play and damage.
If any defect is found, replace.
3) Check propeller shaft center support (1) for biting of foreign mat-
ter, crack, abnormal noise and damage. If any defect is found,
replace.
Drive Shaft Boot Inspction
Check drive shaft boots (wheel side and differential side) for leak-
age, detachment, tear or any other damage.
Replace boot as necessary.

Manual Transmission Oil Inspection and Change
[Inspection]
1) Inspect transmission case for evidence of oil leakage.
Repair leaky point if any.
2) Make sure that vehicle is placed level for oil level check.
3) Remove oil level plug of transmission.
4) Check oil level.
Oil level can be checked roughly by means of filler / level plug
hole. That is, if oil flows out of level plug hole or if oil level is found
up to hole when level plug is removed, oil is properly filled.
If oil is found insufficient, pour specified oil up to level hole.
For specified oil, refer to description of oil change under ON-VE-
HICLE SERVICE in SECTION 7A or 7A1.
5) Tighten level plug to specified torque.
[Change]
1) Place the vehicle level and drain oil by removing drain plug.
2) Apply sealant to drain plug and tighten drain plug to specified
torque.
3) Pour specified oil up to level hole.
4) Tighten filler plug to specified torque.
For recommended oil, its amount and tightening torque data, re-
fer to ON-VEHICLE SERVICE of SECTION 7A or 7A1.
ITEM 6-8
Rear Differential Oil Inspection and Change
(4WD vehicle only)
[Inspection]
1) Inspect rear differential case for evidence of oil leakage.
Repair leaky point, if any.
2) Make sure that the vehicle is placed level for oil level check.
3) Remove level plug (1) of differential. Oil level can be checked
roughly by means of level plug hole.
That is, if oil flows out of level plug hole or if oil level is found up
to hole when level plug is removed, oil is properly filled.
If oil is found insufficient, pour specified amount of specified oil
as given in SECTION 7E.
4) Tighten it to specified torque.
[Change]
Place the vehicle level and drain oil by removing drain plug (2). Pour
specified amount of specified oil, tighten drain plug and filler plug
to specified torque, referring to ON-VEHICLE SERVICE in SEC-
TION 7E.

6-4 ENGINE GENERAL INFORMATION AND DIAGNOSIS (TBI FOR G10)
PRECAUTION ON FUEL SYSTEM SERVICE
Work must be done with no smoking, in a well-ventilated area and
away from any open flames.
As fuel feed line (between fuel pump and fuel delivery pipe) is still
under high fuel pressure even after engine was stopped, loosen-
ing or disconnecting fuel feed line directly may cause dangerous
spout of fuel to occur where loosened or disconnected.
Before loosening or disconnecting fuel feed line, make sure to re-
lease fuel pressure according to “FUEL PRESSURE RELIEF
PROCEDURE”. A small amount of fuel may be released after the
fuel line is disconnected. In order to reduce the chance of person-
al injury, cover the fitting to be disconnected with a shop cloth. Put
that cloth in an approved container when disconnection is com-
pleted.
Never run engine with fuel pump relay disconnected when engine
and exhaust system are hot.
Fuel or fuel vapor hose connection varies with each type of pipe.
When reconnecting fuel or fuel vapor hose, be sure to connect
and clamp each hose correctly referring to left figure Hose Con-
nection.
After connecting, make sure that it has no twist or kink.
When installing injector or fuel delivery pipe, lubricate its O-ring
with spindle oil or gasoline.
When connecting fuel pipe flare nut, first tighten flare nut by hand
and then tighten it to specified torque.
